Question

Short answer question

Name the ovarian hormone and give their functions.

Answer 1

Ovaries secrete the following hormones:

i. Progesterone: It is secreted by the corpus luteum of the ovary after ovulation. It is essential for the thickening of the uterine endometrium, thus preparing the uterus for implantation of the fertilized ovum. It is responsible for the development of mammary glands during pregnancy. It inhibits uterine contractions during pregnancy.

ii. Oestrogen: It is secreted by developing follicles. Estradiol is the main oestrogen. It is responsible for the development of secondary sexual characters in females.

iii. Relaxin: It is secreted by the corpus luteum of the ovary at the end of the gestation period. It relaxes the cervix of the pregnant female and the ligaments of the pelvic girdle to ease out the birth process.

iv. Inhibin: It is secreted by the corpus luteum. Inhibin inhibits FSH and GnRH production.
