Penis Size Defined

A baby boy's penis size at birth can be a concern for parents. Too big? Too small? In this Q&A penis size defined for normal and multiple conditions.

Question

Dr. Greene, my 14-month-old son has a recessed penis. Ever since we had him circumcised, the penis has recessed into a pad of fat surrounding it. In order for it to emerge, we have to push on either side of the pad. Our pediatrician assured us that as he thinned out, it would emerge on its own. This has not occurred and we are worried that part of the circumcision has re-adhered. We have concerns about social, urinary, and erection issues. Please help us. We are having difficulty finding information on this topic. Is there a surgical procedure that would fix this?
Thank you

Dr. Greene's Answer

“It’s a boy!”

When we first glimpse our children in the delivery room, their sex is one of the immediate things we notice. It’s also one of the first things we report to family and friends. In the last generation, many of us have seen evidence of our children’s sex on ultrasound even before they were born, but still at the birth, we look to see.

How disconcerting to parents when a boy’s penis seems to disappear, either at birth or shortly thereafter. The good news is that the outlook is bright. Sometimes surgery is needed, sometimes medical treatments, and often nothing at all.

When a penis appears absent or too small, we call the condition inconspicuous penis (Walsh: Campbell’s Urology, 7th ed., W. B. Saunders Company, 1998). I’ve seen this in a great many boys. Several very different situations are lumped into this category. I will describe webbed penis, concealed penis, trapped penis, micropenis, and absent penis.

A webbed penis is a normal-sized penis where the skin of the scrotal sack extends part way up the shaft of the penis. Boys can be born this way, or the condition can result from an over-exuberant circumcision where adhesions form between the scrotal skin and the penile skin. Webbed penis usually causes no problems (unless a routine circumcision is later performed). It is unlikely to get better as the child grows. Results with surgery, however, are excellent. (Casale AJ – Concealed penis in childhood: a spectrum of etiology and treatment. J Urol – 1999 Sep; 162(3 Pt 2): 1165-8).

A concealed penis is a normal-sized penis that lays hidden in the pubic fat pad. This condition is also called buried penis or hidden penis. Some children are born this way, and for some it happens after circumcision. It is common in infants and toddlers, and occasionally seen in older children and obese adolescents. If the penis can be easily exposed by gently pulling on it or by pressing down on the surrounding fat pad, then the situation will usually correct itself over time. Sometimes surgery is needed for concealed penis. Either way, “social, urinary and erection” results are excellent.

A trapped penis is a normal-sized penis that is partially stuck in the pubic fat pad. Children are not born with trapped penis; circumcision causes it. Routine circumcision of a webbed penis or circumcision when there is significant scrotal swelling (from a hydrocele or hernia) can lead to trapped penis. Scarring or adhesions trap the recessed penis in the fat pad. This condition can predispose children to urinary tract infections or urinary retention. Surgery is usually wise.

 

All of the above conditions have a penis of normal size. In determining size, the “stretched penile length” is far more important than the “relaxed length.” To evaluate penis size, stretch the penis gently and measure from the bone at the base all the way to the tip. Be sure to depress the surrounding fat pad to get all the way to the base. Here are the normal values:

Average Penis Size – Stretched Penile Length 
(Adapted from Feldman KW, Smith DW. Journal of Pediatrics. 1975; 86:395):

Age
Normal: Mean +/- 1 SD (inches)
Abnormal: Mean – 2.5 SD (inches)
0-5 months

Micropenis is a penis that is more than 2.5 standard deviations below the average size for age. In a newborn, a stretched penile length less than ¾ inch (1.9 cm) is micropenis.

Micropenis is a hormonal problem that takes place sometime after 14 weeks gestation when the penis has already formed. Hormone levels need to be checked. A boy’s chromosomes should also be checked to see if there is an underlying genetic syndrome. An MRI may be needed to look at the hormone secreting glands. If the penis grows when a 3 month-trial of testosterone is given, the outlook is good for normal adult penis size and function.

If micropenis does not respond to testosterone stimulation, the difficult question of re-assigning gender arises. This decision has been made even more difficult by conflicting and changing recommendations of experts in the field. (Van Wyk JJ, Calikoglu AS, Should boys with micropenis be reared as girls? Journal of Pediatrics, 1999; 134(5)) At one time, gender re-assignment was the routine choice, even though it involves castration, surgical reconstruction, estrogen supplements, and huge emotional issues for the child and family. (Many people based their opinions on the case of a baby boy whose penis was accidentally amputated during circumcision. When he was 22 months old, he was castrated and reassigned a female sex. He had surgery to make his genitals appear female. He was raised as a girl. At puberty, he was given estrogens to promote breast growth. Reports said that he had a very good adjustment to the female sex, but it later became clear that from an early age he had rejected the idea that he was a girl. During his teen years, he insisted on switching back to living as a man. He later married as a man. (Diamond M, Sigmundson HK. Sex reassignment at birth. Long-term review and clinical implications. Arch Pediatr Adolesc Med 1997;151:298-304.) Recent long-term studies of micropenis, though, have found that even if the penis remains small, most boys-raised-as-boys end up as sexually active, heterosexual males who stand to urinate, have a strong male identity, normal erectile function, and who enjoy sex. (Reilly JM, Woodhouse CR. Small penis and the male sexual role. J Urol 1989;142:569-71.) Their partners also report sexual satisfaction. (van Seters AP, Slob AK. Mutually gratifying heterosexual relationship with micropenis of husband. J Sex Marital Ther 1988;14:98-107.) Teasing from peers can be a real problem, though. A penile prosthesis may help.

Adults who have themselves had intersex issues argue strongly against reassignment before the child is old enough to choose. (Van Wyk JJ, Calikoglu AS, Should boys with micropenis be reared as girls? Journal of Pediatrics, May 1999. 134(5).) Their opinion should be listened to carefully.

Absent penis, or penile agenesis, is very rare, occurring in fewer than 1 in 20 million boys. (Gillenwater JW. Adult and Pediatric Urology. Mosby Year Book. 1991.) The scrotum and testicles usually form normally, but the penis doesn’t form at all. A team including a geneticist, endocrinologist, urologist, pediatrician, and mental health experts should be involved.

Many times, I have looked into parents’ worried faces over their son’s inconspicuous penis. When a boy has an inconspicuous penis, the parents’ concerns are quite understandable. The penis should be promptly examined and measured, and the parents should be clearly told whether it is normally formed and of normal size. Whenever any question remains, a pediatric urologist is the best person to evaluate the penis and recommend a plan. Consulting a urologist is all the more appropriate when new concerns arise as the boy grows.

My question is when you say “stretched penile” too see how long it is do you mean you have to pull it gentle from the head of the penile? My son is 7 months old has a severe hypospadias and i’m curious of the length
Thanks

Hi Matt,

That is correct. Also, press the ruler down gently in the fat pad at the base of the penis so it rests against the bone. Do both very gently.

I hope that helps.

Hello, I have an 11 year old son who will turn 12 in January. He is 5 feet 3 inches tall. He is very slim and doesn’t have a large fat pad surrounding his penis. He was born premature at 35.5 weeks. I had preeclampsia. I was given medication to help his lungs and was then induced. He stayed in the NICU for a little over 2 weeks. He was jaundiced and on a C-Pap for only a short time. During his NICU stay, he was circumcised. We weren’t aware it was happening. Prior to the circumcision his penis looked normal. As odd as it is to say, as a premie, his penis looked larger than it does now. He is a big boy – much taller than most boys his age. The current size of his penis is slightly over 2.5 inches. The size of his penis in relation to his physical size seems wrong. We’ve talked to multiple pediatricians who say he’s perfectly normal. However, his peers, even younger relatives are double his size and width. We finally got a referral for a geneticist who literally looked at him without tests or measurements and said “he’s fine”. Our pediatrician measured him, and stated his within the limit, however when looking at the scale – he’s at the end. He’s the period at the end of a sentence. He didn’t walk until 18 months. Once he began to walk, and after months and numerous appointments requesting tests or info on why he couldn’t walk up steps, wasn’t strong, needed arch support, we were told he was “low tone”. He then saw an endocrinologist who said “he’s fine”. Am I crazy in thinking his penis is abnormal. He urinates fine and looks normal with the exception of the penis size. Is it wrong for me to continue to pursue this? I don’t want to make him self conscious but, I can tell he already is. Is there anything that can be done at his age/size to help him. I’m so concerned with social stigma. He’s already had such a hard time. With low-tone and athletics which he loves. We recently switched to a new hospital and pediatrician. I’d like to contact the doctor prior to the appointment. What I’d like is for him to bypass the pediatrician and see a specialist. Even if he’s within the normal range he’s squeaking by a hair to be in it and I’m not ok with it. Can you please provide advice.

Oh… my…. God…

Leave the child alone. Y’all are the one giving him a complex about his privates. Y’all have taken him to numerous doctors… who constantly measure his penis…. think about this. Really think about what you are doing here. How would you feel if your parents kept doing this to you as a young child? Leave the boy alone, before you end up with a suicidal teen from this crazy nonsense.

“Is it wrong for me to continue to pursue this?”
Yes. Let it go. He’s been told by a number of physicians that he is within the normal limits, and it’s a perfectly functioning penis. Any further pursuit in comparing size will make him more self conscious and create lifelong issues. Boys’ penises grow during puberty and the *average* size for an adult male (erect) penis is a little over 5 inches. Let it go and reassure him that he is everything he should be and penis size isn’t what makes a man a man.

A trapped penis is a normal-sized penis that is partially stuck in the pubic fat pad. Children are not born with trapped penis; circumcision causes it. Routine circumcision of a webbed penis or circumcision when there is significant scrotal swelling this is what happen to my son he is 10 years old and it is really small his brothers are 10 time more then my 10 year old. Before the circumcision it was fine after circumcision Every Retrieve in-and-it hasn’t grown much sense an infant. I am very worried this is the most important part of a man And I don’t know what to do. The Doctors kept telling me it will come out as he lose weight my son lost a lot of weight and it never showed up He often ask me and dad why do it go inside and why is it so small. My main concern is why isn’t it growing.to me this is an Estimate 1.2 for a 10 yrs old. I don’t think its right. I have 3 boys My youngest is the only one with this problem. I have seen similar Situations With a couple of my family members and one friend. my family member Grew over time but I have a friend his never grew and its still retrieves and very small. I don’t want this To happen to my son. I need to fix it while hes young. This can lead to many problems depression low self esteem. I want to fix it while hes unaware of what’s really happening.

I am 11 and I have a [redacted] penis it has hair on it. did I hit puberty?

I’m 11 years old and I can’t pull my foreskin back at all. Is there something wrong with me

Hi Anonymous,

In an article about cleaning an uncircumcised penis, Dr. Greene says, “If urine can flow freely, the hole in the foreskin is big enough. As long as the foreskin doesn’t easily retract (even in a ten-year-old), only the outside needs to be washed.” Since he called out “even in a ten-year-old” it is logical to think that is the upper limit of normal.

It’s likely time to discuss this with your doctor. Of course, the first step is to talk to your parents about it if you haven’t already.

I hope that helps.

My 5 year old son penis is 1.7 inches. Is that abnormal?

I am 15 years old and my penis is [redacted]. It is also noticeably smaller than my 3-year-old brother’s. What should I do?

I been that way my whole life and I’ve had good relationships with women I have three grandchildren at this point.I wasn’t going to add this but I am because I think it’s crucial make sure that you stand to go to the bathroom don’t be afraid to urinate in front of other men. I didn’t enter the military because I knew that I couldn’t go to the bathroom in front of other men .Trust me it’s no laughing matter as it has complicated sporting events as well as just going into a public restroom and wanting to stand .I have effectively kept secret for over 50 years now not even my son knows.Be a good man and you follow through with the things you need to in life you will be like any other man and maybe even better! Treat women with courtesy and respect. Always protect women.

Jack,

From the info you provided, I’m guessing your size is smaller than your younger brother when it is soft. The size you stated when hard would be extremely large for a 3-year-old.

Depending on your stage of development, your size when hard is likely normal and there’s nothing to worry about.

I hope that helps.

Hi Dr.Gre.

Im an Asian Mom,
Im worried on my Son’s penis, He is now 4yrs of Age and i have 1yr old son also,

Im noticing something about the size of his penis because my 1yr old son is a bit bigger/ i mean the legnth of his penis is different,

Im comparing it to my 1yr old son is really look small, it this can be a issue for us? I mean where asian Its common that our partners doesnt have that size as the other nationality, but it gives me concern while im comparing it to my 1yr old son to his Older brother size as 4yrs old already.

The penis of my son 4yrs
Old is a bit smaller that to my son 1yr old..

Can you please give us a feedback about my concern so we can know the right person to give our concern. ( i mean a doctor to contact with or specific person to give our concern.)

Im currently in Kuwait rightnow.

my penis size is small. what I have todo

My bf is 17 yrs old, though he has small penis. Is he reqire any checkup? Is this effect in having a baby?

Natural selection has not eliminated small penis. I think you will be fine. Just experiment with different positions. There are at least 4 ways to get in there. 5 including ivf

Dear Dr.

My question could be unusual perhaps. I am 38 year old male who recently got circumcised due to several reasons (medical).

It’s only been a little over three weeks, and all the sutures are gone and I generally feel good and comfortable. However, I have noticed a significant shortening in the erect state. I have not measure anything precisely, but my guess would be at least 1 to 1.5 inches.

One more thing is that the size is reaching more pre-circumcised state as the time is passing by. In other words, the first few erections after circumcision were much more shorter, and now the penis size has come up a bit. Is this possibly due to the skin stretching with more erections? I did talk to my surgeon who said, I will get back to my full size with time once the skin gets a chance to keep stretching.

I have read a lot about tight (high, low) styles etc. I want your opinion on this, if I will be able to get back to my full size or will the shortening be permanent?

Thanks a lot!

My son is 7 years old. His penis is too small and even his testicles are not very visible. i have not measured his penis but i looks small. he was circumcised at the age of 4. i have 2 younger boys and both’s penis size looks normal.

Should i consult pediatrician or urologist?

My son is 2.5 years old. We had issues with his foreskin reattaching between 12 months and 24 months of age. It is no longer stuck but he seems much smaller than our 3 week old son. May I add, my 2.5 year old has retracting testicles where sometimes they’re in the scrotum and sometimes they aren’t. Can undesended testicles make the penis appear smaller?

I’m so glad I found your site read everything, and all comments. Learned alot for the fear of my grandsons very small penis. After reading all I now think I know what he has and have nothing worry about.
Thank you, Dr. Greene.

I am 50 now and was born with a Micropenis, my penis has hardly grown since I was around 8 years old.
you should keep a growth chart and really keep up with your son’s penis size. I wish mother would have, and maybe the doctors could have done something. If anyone is interested I started a Micropenis journal. I hope someday an affliction like Micropenis won’t be joked about or even laughed at.

Pls provide journal

The obgyn told me my sons penis is too small for her to circumcise it. We took him to his pediatrician at his first newborn appointment and was told it’s not too small and she sent us to a pediatric urologist. She performed the circumcision but never commented on the size being too small but now , my son is 3 months and I feel like it’s too small. He’s border line Micropenis. Not sure if I should worry.

My son is 12 and his penis hasn’t grown since birth, he is tiny. He had issues with his foreskin being stuck and ended up getting circumcised. Could this be why he isn’t growing?

Hi
My son age is 13 years I am worried for him because his penis is to small and skin is loose to down side still we r not consulted Gp so please help me .

Dimple

Get his hormone test done, T3,T4 and TCH. Based on report ur doc should able to give u treatment. It’s usually intra muscular testrone injection for 3 months 1 each month or if the TH level is too low Thn it will be 1 weekly fr 3 weeks

My kids 10. When we want to know the normal health penis size according to the chart are we looking at a erected penis ora normal penis. He is overweight 60 kilos.

Ashna,

In medicine, the penis is measured as in the stretched length. Dr. Greene describes how to do that: To evaluate size, simply stretch the penis gently and measure from the bone at the base all the way to the tip. Be sure to depress the surrounding fat pad to get all the way to the base.

I hope that helps.

My son is 4. He is very slight in build and is 99cm tall.
His penis is just over 1.5”. Should I take him to gp?.

Hi, my son 6 weeks old, has a penis length of 2.5cm measured by doc. He has a hydrocele so you cannot see his penis shaft. He has been given testosterone to promote growth. How long until we see results?

My wife is worried about my 8 month son panis i am far from them she saying our son panis is not like other same age kids what should we do plz

Hi !
I just saw a pediatric doctor for the penis of my 8months baby.
His penis is hidden… but we only get 3cm mesurement.
She said that its not a micropenis…. but i have a doubt….. what you think :(?

(My baby still have galactorhea too!!!)

Hi Dr Greene
Im really worried im not normal as wikipdia states Tanner scale 5 penis is 15cm mine flaccid is about 3.5 inches in 18 and am v depressed about this. I went to the Doctor she just said stop worrying and prescribed 2mg Diazepam please help

The medical literature is comparing stretched length. Are you measuring the stretched length?

Here are the instructions: In determining size, the “stretched penile length” is far more important than the “relaxed length.” To evaluate penis size, stretch the penis gently and measure from the bone at the base all the way to the tip. Be sure to depress the surrounding fat pad to get all the way to the base.

I hope that helps.

I don’t think wikipedia is right on this one. Look at what this article says.

My grandson aged 14 years is having penis size of around 5.5 inches in unerected condition.
Is it not a concern? will it keep on growing?
When he was 10 years old I noticed the penis bit long I took him to an endocronogilist who said he was attaining early puberty & he administered injection every month till the age of 13 What should I do?

My 8-year old has a very small penis compared to other boys his age. I’m worried if it is true that soy-based formula feed baby will have genital abnormalities before reaching puberty due to a compound called genisteins produced by soy which act in the body to mimic the effect of estrogen. When my son was still a baby he was allergic to cow-based formula so his pedi gave him soy-based formula. Is it really hormonal issue why he’s having small penis? Should I bring him to a specialist? His pedi before didn’t mention any negative effects of soy formula. My daughter also was soy-based formula fed and she started having an underam odor at the age of 5 which is too early, she’s now 7. They said it was because of the milk she had when she was a baby. Now, I have a one month old baby who’s also a soy-based formula feed, I’m too worried for he might be like his older brother when he grows up. Please help. Thank you.

Don’t give them soy at all. It’s not good for us.

Hi there. My son was also given soy based formula as a baby due to allergies and seems to be experiencing the same issue as your son. Could you please tell me what information you have learned since your post. Thank you

hello doctor
my son is 6 and half years old, his penis size is smaller, if compare to the boys of his age, he didn’t had any complications after his birth. is it normal? should I wait for some more time?

When one testicle seems bigger than the other, it’s important to consider the possibility of a hernia or a hydrocele (a collection of fluid). The two articles linked here describe both conditions and what to do. If possible to have someone knowledgeable examine your son, that would be great. Best, DrGreene

When they say stretched penis is this the same as an erect penis?

Hi Lee,

Thanks for writing in.

A stretched penis and an erect penis are NOT the same thing. Here are Dr. Greene’s directions for measuring the stretched penis: “To evaluate penis size, stretch the penis gently and measure from the bone at the base all the way to the tip.

My son is 10 and his penis has not grown his penis look like it hides he say that it out when he wakes up then it hides it look k s like a baby should I be worried but he is a big boy he pushing 170 is a that part of the problem

As an old boarding school hand I can tell you that pre-pubertal boys do display a range of penis sizes,(not as much as adults obviously), that as a rule they don’t grow incrementally, they stay infant size until suddenly growing as puberty kicks in and that a three year old could be better endowed than his pre-pubescent 15 year old brother……I know this from sharing a beach hut and an eagle-eyed, loud-mouthed sister with said three year old!

Pre-pubescent at 15?? That’s called delayed puberty… I was bigger than most adults at 15…

Hi Dr Green, my son is 10 years old and l have noticed recently that he is hiding his penis and we believe that it’s due to his size, he is a Botton sized while his 4 year old brother is around the 2inches. He had a small cyst removed at 7 months old from his right testical. Could this have effected his penis growth. He is a bigger boy at 150cm in height and weights 56kg but very active. Please help as we don’t want him to suffer growing up and is there anything that you recommend we do for him.

Hi Natasha,
Thanks for writing in!It would be wise to have your son examined by a pediatrician or pediatric urologist. He will be able to tell you and your son if he is on track for his age and stage of development. If he’s not, the doctor will be able to help you with next steps.

My sons 2 and has a 4 inch penis!
Is that normal for a kid his age?

No

depends on how big your husbands penis is and your fathers
but when I was a 2 I was like the same as yours but this is really big for his age

I am worried about the size of my 10 year old son.His penis length is obviously less than 2inches. I have taken him to a doctor and I was reassured that all is normal.I continously and unconsciously compare him with his 8 year old brother whose penis appears relatively more in girth and length.I hope am not unnecessarily agitated but for sure I need to allay my fears.

My son is the same and l compare him to our4 year old who already has a 2inch penis. I also have just posted and asked for recommendations. Hope all works out for your boy.

My son is days away from being six years old and his penis is tiny. He was circumsized at birth and again at age 4, because something wasn’t done right the first time. I have never seen it “get hard” or even move. Is this normal? I don’t understand any of this seeming as I am a female. What size should a six year old be? My boyfriend’s son is turning 3 in February and he has a large penis that gets to about 2 inches when he is errect (peeing). It’s just big in all aspects. Why is my son(a 6 yr old) so small compared to a 3 year old?

AJ,

Dr. Greene says it would be wise to have a doctor examine your son. Sometimes the penis is hidden in a fat pad and is perfectly normal. Other times there may be an issue. Either way, having him checked is a good idea.

I hope that helps.

Folks, Don’t give your kid a complex!
If you are going to measure his penis, measure other things at the same time. Measure his height, the length of his fingers, the girth of his ankle, etc. Make measuring his penis just part of something that makes it seem routine. If you just lay him down and slap a ruler against his penis, he’s going to remember that and start worrying.
Sure, if he’s come to you and said he thinks his penis is smaller than his friends, you can say, “Well, maybe there’s a problem. Let’s see how long it is so we can check with a doctor if it’s not developing as it should.” But if he’s not raised the issue – and is over 5 or so – don’t plant the concern in his head.
Guys worry about size too much already. Having mom or dad slap a ruler on an 8 to 11-year old is only going to make things worse.
I really don’t understand why the doctor hasn’t mentioned this.

Thanks for this advice. I’ve been worried about how do I begin to measure my little boy without making him aware as he is already a shy boy.

I’m glad I read your post. I didn’t think about that. Very smart.
Thank you.

Hi Dr Green, what is the side effects of testosterone injection for 5 year old boys?

Maybe not circumcising would solve a lot of these issues.

Does the penis grow every year until puberty begins?

Hi Dr.Greene.com,

I just got back from the pediatrician with my 4yo son, and while based on your chart here he doesn’t quite have a micropenis, he is almost half the size of what he should be and only a hare’s breath away from a micropenis.
I’m planning to take him to an endocrinologist, and wanted to know what treatment options (aside from testosterone) we can expect, and how are the outcomes for these boys if testosterone doesn’t work? Also, does their penile growth pattern generally follow their childhood size into adulthood? As in, if he is about half size now, and nothing works, is it likely he’ll remain about half the normal size into adulthood?
Sorry for the awkward questions, I’m just concerned for him. Thank you for the help!

My Son’s penis is very very small compared to his friends & they give him grief over it. What should I do?

How do you know what your sons friends dicks look like

Belinda,

It would be wise to have your son examined by a pediatrician or pediatric urologist. He will be able to tell you and your son if he is on track for his age and stage of development. If he’s not, the doctor will be able to help you with next steps.

For more information about stages of development, see Penis Size During Puberty.

Hope that helps,

My boy is 10 years old and his penis is less then 2.4 inch. His 1.3 m and weight 34 kg it never bother him before but have asked me about it why his is smaller then his class mates. His healthy boy, no smoking or drinking or any rare diseases in the family history

My penis is that small hard and I’m 16 soo he’s lucky

My Son’s penis is very very small compared to his friends & they give him grief over it. What should I do?He is 10 & healthy.

My 11 year old son is circumcised since the first week after birth. His penis always looks like it is sticking straight out and he is constantly adjusting himself because it is uncomfortable. It never hangs or dangles. He is not over weight and very athletic. What should we do if anything?

Start out by talking with your pediatrician. He or she will likely do a physical exam and give you suggestions. If your pediatrician hasn’t been helpful, you could see a urologist.

Hope that helps,

i am worried that my 11 year old son has a problem with his penis, you can’t see it unless you pull the skin back BUT he is circumcised. My husband reckons it will correct itself but I can’t help but think there’s more to it……I also feel that his circumcision wasn’t done correctly as he still has a bit of skin around his penis and when it’s pulled back you can then see his penis.

To ‘Worried mam’:
With all due respect to Dr. Greene (& this wonderful forum of advice), I wouldn’t give my business to any doctor who asked a mother to leave the room so he/she could examine her 11 year old son.
You brought this child in the world & you have every right to be there for that full examination. If there’s something wrong with you (his mother) seeing your sons penis than there should be something wrong with a doctor seeing it too. In actuality, our society should stop shaming the innocence out of kids concerning nudity.

While I don’t feel it would be appropriate for a father to be in an exam room with his daughter beyond this age, a mother being with her son even into his early teens shouldn’t be a problem. It’s important for boys to not be shamed into self conscience bashfulness. That’s medical knowledge that goes way back. Sadly, in recent years some of this knowledge has been set aside

I’d schedule an appointment for a physical exam with his pediatrician. At his age, the pediatrician will likely ask you to leave the room for the exam. Be sure to mention your concern before you go, or better yet, talk to your pediatrician before the appointment and tell him your concern when your son is not able to hear the conversation. There’s no need to suggest your concern to your son, but he deserves to be checked. If your current pediatrician isn’t concerned, get a second opinion just to be sure.

Good Day,

Is it possible for my baby’s penis to grow closed. When he was smaller nurses told me not to pull back the foreskin and now I see that the tip of the penis is not a very pinkish colour. Its hard to pull the skin away and expose the penis. Is surgery needed or can I help him at home?

Greetings, Simone

My son had a similar issue, but when his penis started to grow in puberty the skin around it developed normally and all is fine with him now.

I hope this was helpful.
With best regards, Alex

Hi there,

I am very worried mom. My elder son is 4.8 years old and weighs about 22kg. His penis size before erection is half inch and after erection is 1.1 inch. I know this is small Is it micro-penis? Will face difficulty in his sex life?

Dr. Greene,

My son is 7 months old and when I push the skin back, his penis is still less than an inch. It’s maybe 2 cm. :/ I switched pediatricians because the first one told me he had a small penis and joked about it. I was mortified. I want to make sure my son is okay and make sure he does not need hormone therapy or anything like that. Could you please direct me to a doctor in the New York area. I live in Nassau County on Long Island. Thank you in advance for any advice you can provide.

Best regards,
Lisa

My son is almost 5 months old. He has a big penis. Its like the size of a 3 yrs old. I noticed it after circumcision. Should I be worried?
