Question

Which hormone is secreted in large amounts by the corpus luteum to maintain the endometrium?

Answer 1

Corpus luteum:

1. The ruptured Graafian follicle ( present in the ovary) is transformed into the corpus luteum after ovulation.
2. The corpus luteum secretes mostly progesterone.

Progesterone:

1. It is vital for the endometrium's maintenance, which is required for the implantation of the fertilized ovum and subsequent pregnancy events.
2. Progesterone is a hormone that helps with pregnancy.
3. Progesterone also stimulates the formation of alveoli (milk-storing sac-like structures) and milk secretion in the mammary glands.
