Physiology_Flashback:
Hypothalamus produce
Gonado-
Trophin Releasing Hormone ( GnRH) which in turn stimulate the Pituitary gland to release, the
Follicular Stimulating Hormone (FSH) & Leutenizing Hormone (LH). FSH & LH influences the gonads (The testis and the ovaries).
#Notes:
F
SH stimulate
Sertoli cells(S forS) .
LH stimulate
Leydig cells(L for L) .
Leydig cells is an endocrine cells that produces
Testesteron.
Sertoli cells produces Androgen binding protien to keep Tetstesteron concentration high within the testis.
Leydig cell tumor is the commonest Stromal Tumors.
Stromal tumor present with painless testicular mass and excessive androgen(estrogen and testesteron).
Gynecomastia, acne and precious puberty are the classical symptoms.
It is not an unusual for leydig cell tumor to secrete #Estrogen.
Tetstesteron important in spermatogenesis, male genital organ development and secondary male sex characteristics.
