Question

the major source of estradiol and progesterone in a non - pregnant woman is the

multiple choice

thyroid gland.

adrenal gland.

testis.

ovary.

uterus.

Explanation:

• The thyroid gland produces thyroid hormones like thyroxine and tri - iodothyronine, not estradiol and progesterone.
• The adrenal gland produces hormones such as cortisol, aldosterone, and some androgens, not the main source of estradiol and progesterone in non - pregnant women.
• The testis is a male reproductive organ and not relevant to hormone production in women.
• The uterus is mainly involved in pregnancy (implantation, gestation) and menstruation, not a major source of estradiol and progesterone.
• The ovary is the primary female reproductive organ. In the menstrual cycle, the ovarian follicles (before ovulation) produce estradiol, and the corpus luteum (after ovulation) produces progesterone.

Answer:

ovary.
