What is the role of LH in spermatogenesis? What is the role of FSH in spermatogenesis?...

What is the role of LH in spermatogenesis? What is the role of FSH in spermatogenesis? Suppose a male had a dysregulation of the interstitial endocrine cells and secreted an excessive amount of testosterone. What would happen to blood levels of LH and FSH?

Answer #1

Spermatogenesis is the process in which haploid spermatozoa is formed from gem cells in the seminiferous tubules.

LH is the luteinizing hormone which is secreted from anterior pituitary acts on gonads

LH has little role in spermatogenesis, it stimulates production of testosterone from the leydig cells. Intern this testosterone helps in spermatogenesis.

FSH is the follicular stimulating hormone secreted from anterior pituitary acts on sertoli cells to produce androgen binding protein and formation of blood testis barrier.

FSH indirectly produces testosterone which helps in spermatogenesis.

When there is increased testosterone levels in the blood it gives negative feedback mechanism.

Acts on hypothalamus ang inhibits production of GnRH, LH, FSH from anterior pituitary. So that blood levels of LH, FSH reduces.
