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

In a developed ovary, a female fetus typically has around 1-2 million primordial follicles. These follicles contain immature eggs (oocytes). As the individual matures, the number of primordial follicles decreases, and only about 300,000 to 500,000 primordial follicles remain at puberty. By the time of menopause, the number is further reduced. Thus, the correct answer is 1-2 million.
