Question

The hormone that maintains the endometrium of the uterus is secreted by______

• A. ovary
• B. hypothalamus
• C. uterus
• D. anterior pituitary

Answer 1

The correct option is A ovary

The hormone that maintains the endometrium of the uterus is progesterone. It is secreted by the corpus luteum of the ovary which is a temporary endocrine gland.
The Graafian follicle gets ruptured to release the secondary oocyte. The ruptured Graafian follicle converts into a yellow coloured body called corpus luteum.

Maintenance of a thick endometrium is necessary during pregnancy as the embryo gets implanted in the endometrium.
