Question

Name the endocrine structure found in empty Graafian follicle. What role

does it play during pregnancy?

Answer 1

The empty graafian follicle or tertiary follicle collapses. The ruptured vessels bleed into antrum and remaining granulosa cells then invade area and proliferate to create an endocrine structure known as corpus luteum. Corpus luteum secrets hormone progesterone. Progesterone is important for maintaining pregnancy as it makes the uterus ready for implantation.
