Two types of hormones are secreted by the ovaries: estrogens and progestogens. Estrogens (follicle hormones) are secreted by the graafian follicles. Progestogens, example progesterone, are secreted by the corpus luteum.
Estrogens
Estrogens stimulate the formation of female secondary characteristics like the development of mammary glands, broader pelvis, increase in adipose (fat) tissue, etc. It prepares the uterine wall for proliferative growth of its lining (endometrium) and promotes the development of fallopian tubes.
Progesterone
The hormone progesterone promotes the development of uterine endometrium for nurturing the embryo. It maintains pregnancy and suppresses ovulation and reproductive cycles during pregnancy.
