MICROANATOMY

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: -Women may make new eggs throughout their reproductive years-challenging a longstanding tenet that females are born with finite supplies, a new study says. The discovery may also lead to new avenues for improving women’s health and fertility. A woman has two ovaries, which release eggs during her monthly ovulation.

Detailed explanation-3: -A girl is born with all the eggs she will ever have. Male: While women are only fertile during a few days in their menstrual cycles, men are constantly fertile from the onset of puberty (usually at 10 years of age) when a surge in testosterone triggers the production of an average of 200 million sperm each day.
