Question

A human female is born with a million of eggs(primary oocyte) at the time of birth, only some $500$ eggs get a chance of maturity. What is the destiny of rest of the eggs?

• A. Rest of the eggs differentiate back to thecal and granulosa cells
• B. Rest of the eggs nurture the dominant follicular cell
• C. Rest of the eggs move out of the ovary and are destroyed by leucocytes
• D. Rest of the eggs break down and are absorbed i.e., degenerative follicular atresia

Answer 1

The correct option is D Rest of the eggs break down and are absorbed i.e., degenerative follicular atresia

Women are born with approximately two million eggs in their ovaries. From birth on, they decrease in number by a process called atresia. As a teenager, a woman has only 300 to 400 thousand remaining eggs and that point on, approximately one thousand eggs are destined to die each month. Hence the correct answer is option D, Rest of the eggs break down and are absorbed i.e., degenerative follicular atresia.
