Question

which of the following secretes progesterone?
a.) theca cell
b.) corpus luteum
c.) granulosa cell
d.) oocyte

Explanation:

The corpus luteum is formed from the remnants of the follicle after ovulation. It secretes progesterone, which is crucial for maintaining the endometrium (lining of the uterus) in case of pregnancy. Theca cells are involved in androgen production (which can be converted to estrogen in granulosa cells). Granulosa cells are more associated with estrogen synthesis (in cooperation with theca cells via the two - cell two - gonadotropin hypothesis). Oocytes are the female germ cells and do not secrete progesterone.

Answer:

B. Corpus luteum
