Explanation: 

Detailed explanation-1: -Current knowledge indicates that females are born with their entire lifetime supply of gametes. At birth, the normal female ovary contains about 1-2 million/oocytes (eggs). Females are not capable of making new eggs, and in fact, there is a continuous decline in the total number of eggs each month.

Detailed explanation-2: -A female is born with all the eggs that she is going to have throughout her lifetime, which is approximately 2 million eggs. No more new eggs are synthesized or added after that. One egg is released from either of the two ovaries in each menstrual cycle.

Detailed explanation-3: -How many eggs are humans with ovaries born with? As a fetus early in development, a baby with ovaries has around 6 million eggs. The number of these eggs (oocytes, to be precise) is steadily reduced so that when the baby is born, they have between 1 and 2 million eggs left.

Detailed explanation-4: -2. How many eggs does a woman produce each month? Normally, a woman produces one egg each month during her ovulation. During fertility treatment, it is possible for women to produce more than one egg each month, as hormone injection increases the production.
