Question

1. Review the influences of hormones FSH and LH on the male and female reproductive systems?

2. What are the factors that influence the net filtration rat?

Answer 1

Luteinizing hormone (LH) and follicle-stimulating hormone (FSH) are called gonadotropins because stimulate the gonads -the testes in males, and the ovaries in females.

LH EFFECT:

In males, LH stimulates production of the sex hormones (androgens) by the Leydig's cells (Interstitial cells) of the testes and therefore is also called interstitial cell-stimulating hormone.

In females, the ovary theca cells respond to LH stimulation by secretion of testosterone, which gets converted into estrogen by adjacent granulosa cells. It also causes the ovulation from a mature Graffian follicle via preovulatory LH surge. Later this LH is required for continued development and function of corpora luteum.

FSH EFFECTS:

In males, FSH is critical for sperm production i.e. Spermatogenesis by supporting the function of Sertoli cells, which in turn support many aspects of sperm cell maturation. This is inhibited by the hormone inhibin released by the testis.

In female FSH stimulates the maturation of ovarian follicles. It can also cause superovulation when administered in humans or animals.

Hope this helps. Please let me know if you have any query.
