Which organs of the female reproductive system produce hormones?
The primary organs of the female reproductive system that produce hormones are the ovaries, which secrete estrogen and progesterone. The adrenal glands also produce small amounts of sex hormones, including androgens and estrogens. Additionally, the placenta produces hormones during pregnancy, such as human chorionic gonadotropin (hCG) and progesterone, which support fetal development.
Where does the placenta synthesize progesterone from?
The placenta synthesizes progesterone primarily from pregnenolone, which is derived from cholesterol. Maternal cholesterol is converted to pregnenolone in the placenta, and then it undergoes several enzymatic transformations to produce progesterone. This hormone is crucial for maintaining pregnancy by supporting the uterine lining and preventing contractions. Additionally, some progesterone is also produced from maternal and fetal adrenal precursors.
What steroid does the placenta produce during pregnancy?
During pregnancy, the placenta produces several hormones, with progesterone being one of the key steroids. Progesterone helps maintain the uterine lining, supports fetal development, and prevents contractions. Additionally, the placenta also produces estrogens, which play a vital role in regulating various physiological changes during pregnancy. Together, these steroids are crucial for a successful pregnancy.

How is estrogen produced?
Estrogen is produced in the ovaries, primarily the theca (wall) of developing follicles in the ovary, though also to a lesser extent the corpus luteum (remaining outer 'shell' which previously contained an egg) and, during certain stages of pregnancy, the placenta. Some estrogens are produced in smaller quantities by liver, adrenal glands and the breasts.These secondary sources of estrogens are especially important in postmenopausal women. Fat cells produce estrogen as well.
