Question

What happens to the dominant egg in post-pubertal females?

Answer 1

Post-pubertal females:

1. Post-pubertal females are those who have attained the age of puberty/sexual maturity and show cyclic changes in their uterine wall every month, a phenomenon called the menstrual cycle.
2. Such females contain fluid-filled cavities that contain the dominant egg/ovum inside their ovaries. These cavities are called follicles.
3. One such mature fluid-filled cavity is called the Graafian follicle.
4. On maturation, the Graafian follicle bursts and releases a fully mature dominant egg inside the fallopian tube/oviduct towards the uterus.
5. Inside the uterus, the egg remains for about 48 hours.
6. During this time, in the absence of fertilization with a sperm, the egg eventually dies. Following this, a new cycle of egg maturation starts and follows the same cyclic events.
