Definition of Sertoli-Leydig cell tumor
Sertoli-Leydig cell tumor is a rare cancer of the ovaries. The cancer cells produce and release a male sex hormone.
The Sertoli cells are normally located in the male reproductive glands (the testes). They feed sperm cells. The Leydig cells, also located in the testes, release a male sex hormone called testosterone.
