Question

Enumerate the events in the ovary of a human female during follicular phase of menstrual cycle.

Answer 1

This phase also begins on the first day of menstruation, but it lasts till the 13th day of the menstrual cycle. The following events occur during this phase:

• The pituitary gland secretes a hormone that stimulates the egg cells in the ovaries to grow.

• One of these egg cells begins to mature in a sac-like-structure called follicle. It takes 13 days for the egg cell to reach maturity.

• While the egg cell matures, its follicle secretes a hormone that stimulates the uterus to develop a lining of blood vessels and soft tissue called endometrium.
