Question

The total number of eggs produced by a healthy human female during life time

Answer 1

approximately 640 to 665

Answer 2

Normally only one egg matures in each ovary every alternate month.
So for a year, a healthy human female produces 12 eggs.
The reproductive period is from 13 to 45 years (average).
45 - 13 = 32 years is a healthy female's reproductive period.
The total number of eggs produced by a healthy female in her lifetime.
                                                           = 12*32 = 384 eggs(on an average)
