Question

In developed ovary, how many primordial cells are present?

• A. 1-2 million
• B. 500,000
• C. 10,000
• D. 50,000

Hint:

The depletion of primordial follicles over time is a key factor in fertility and reproductive health, with fewer eggs being available as a woman ages.

Answer 1

The Correct Option is A

A developed ovary in a female fetus typically contains approximately 1-2 million primordial follicles, which house immature oocytes. This number declines significantly with age, leaving an estimated 300,000 to 500,000 primordial follicles at puberty. Further reductions occur by menopause. Therefore, the initial count is 1-2 million.
