PATHOLOGY

Detailed explanation-1: -In humans, fewer than 300, 000 of the original pool of about one million healthy oocytes present at birth survive to puberty5, 6. This number continues to decline throughout adulthood to the point of extinction around age 50, thus driving menopause.

Detailed explanation-2: -By the time a woman is born, they have 1-2 million eggs remaining, and by the time they hit puberty, they have around 300, 000-400, 000 eggs. In a woman’s reproductive years, they will lose roughly 1000 eggs but ovulate only one egg each month.

Detailed explanation-3: -Females are born with between one and two million eggs. The number decreases until a person stops ovulating and reaches menopause. At that point, fewer that 1, 000 remain.

Detailed explanation-4: -A woman is born with all her eggs. Once she starts her periods, 1 egg develops and is released during each menstrual cycle.
