Question

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

Answer 1

This phase begins on the 15th day and lasts till the end of the cycle. The following events occur during this phase:

• The egg cell released during the ovulation phase stays in the fallopian tube for 24 hours.

• If a sperm cell does not impregnate the egg cell within that time, the egg cell disintegrates.

• The hormone that causes the uterus to retain its endometrium gets used up by the end of the menstrual cycle. This causes the menstrual phase of the next cycle to begin.
