(Males)Gonadotropin Releasing Hormone(GnRH)

Answer 1

Produced by the hypothalamus

Question 2

FSH(males)

Answer 2

Produced in the Anterior pituitary, stimulates sperm production in seminiferous tubules

Question 3

LH(males)

Answer 3

Produced in the anterior pituitary, stimulates interstitial cells to produce testosterone

Question 4

Inhibin

Answer 4

Produced in steroli cells, inhibits FSH production to regulate sperm production

Question 5

Testosterone

Answer 5

Produced in the Testes(interstitial cells), developes sperm, male traits and sex drive

Question 6

Hormonal feedback loop in males

Answer 6

Release of GnRH from hypothalamus triggers release of FSH and LH from A.pituitary. FSH stimulates sperm production and LH stimulates the release of testosterone from interstitial cells

Question 7

Andropause

-Fatigue, depression, muscle loss, prostate growth

Question 8

GnRH(female)

Answer 8

Produced in hypothalamus, activates the pituitaru to release FSH and LH

Question 10

LH

Question 12

Progesterone

Answer 12

produced in ovaries(corpus luteum), Maintains pregnancy, inhibits ovulation and prevents uterine contractions

Question 13

Inhibin

Answer 13
