estrogens

progesteron + estrogens

36
Q

Estrogens:

A

A

(from the ovary)

  • regulate menstrual cycle
  • maintain pregnancy in presence of developing embryo or fetus
38
Q

Testes hormones:

A

testosterone

39
Q

Testosterone:

A

(from the testes)
stimulate development of male sex organs, secondary sexual characteristics, and behavioral features
-functions of testosterone and its secretion is tied to secretion of LH from anterior pituitary gland
