Question

Select ALL options that APPLY regarding reproductive physiology:

(a) A large decrease in the circulating levels of human chorionic somatomammotropin in a pregnant woman will affect the mother and her fetus

(b) Anti-Müllerian hormone (AMH) is synthesized in males and females

(c) Testosterone is sometimes involved in positive feedback with anterior pituitary hormones

(d) Progesterone can be produced by granulosa cells and the corpus luteum

(e) Males have thecal cells in their gonads

Answer 1

a] Human chorionic somatomammotropin is produced by the placenta and plays an important role in regulating metabolism in the pregnant mother and the fetus which is necessary for normal fetal development.

b] AMH is made in the reproductive tissues of both males and females.AMH is synthesized by the Sertoli cells and plays a key role in the development of internal male genitalia in the developing male fetus. In the absence of AMH, the female sex organs develop.

c] Raising levels of testosterone work as negative feedback on the hypothalamus and anterior pituitary

d] Progesterone is needed to sustain pregnancy and is produced by the ovaries and the placenta in pregnant women.

e] Thecal cells care endocrine cells associated with ovarian follicles and help in ovarian estrogen biosynthesis.They are not found in male gonads.
