A woman in her prime reproductive years – 20s – has as 26 percent chance of getting pregnant with the one natural egg her body produces each month. Don’t despair if you are in your 30s or early 40s. Your quality eggs can still make a healthy baby. A woman is born with between 1 and 2 million eggs – however – she only releases 300 to 400 eggs through each natural ovulation cycle during her lifetime. Typically, a woman only releases one egg per month during her natural cycle. New Hope Fertility NYC’s policy: It only takes one good quality egg to have a healthy baby.
