How many eggs does a woman lay in her lifetime?

Menarche is an important sign of female maturity. It is of great significance to women. As we all know, women start to ovulate when menstruation appears. So how many eggs can a woman produce in her lifetime? Most women don’t fully understand this issue. In fact, a woman ovulates 400-500 mature eggs in her lifetime, and a woman ovulates approximately every 30 years.

1. How many eggs does a woman lay in her lifetime?

Women ovulate regularly every month, but how many eggs will they ovulate in their lifetime? Let’s do the math together!

Women experience two growth periods and one weak period from birth to old age, namely infancy, adolescence and old age. Female ovulation begins at the age of about 13 when the female organs begin to develop during the second menstrual period. Usually one egg is ovulated during each menstruation. In special circumstances, two or more eggs may be ovulated, which is rare. The menstrual cycle is generally 28 days, but it may be longer or shorter. When women reach around 50 years old, their organs gradually age and their ovaries stop ovulating, and menopause begins. A woman ovulates about 500 times in her lifetime. There are hundreds of millions of follicles in the ovaries, and basically there is no chance for them to be discharged and die inside. The better ones will be successfully discharged and have the chance to combine with sperm to give birth to new life.

According to scientific research, observation and statistics, a woman releases 400-500 mature eggs in her lifetime. Normal women usually release one egg in one menstrual cycle, but some women may release two eggs in one menstrual cycle. Normal girls start menstruating at the age of twelve or thirteen and reach menopause when they are nearly fifty years old. I have my period once a month, and I usually release one egg each time, but occasionally two. So that’s about 12 per year, and more than 400 in a lifetime. That is to say, a woman's ovulation period is about 30 years. With the cessation of ovulation and the arrival of menopause, women will enter old age.

2. Egg survival time

The egg does not exist forever after it is released; it has a survival time. So how long does the egg survive? Let’s take a look.

For a woman, the possibility of pregnancy begins with the two ovaries, small, oval-shaped organs attached to either side of the uterus that are filled with eggs. Women of normal reproductive age ovulate once a month, approximately 12-16 days before the next menstruation. The egg has the strongest fertilization ability within 6 hours after being released from the ovary, and can maintain fertilization ability for about 30 hours. After that, the egg begins to degenerate, and the fertilization ability rapidly weakens and disappears. Although sperm ejaculated into the female reproductive tract can survive for up to 4 to 5 days, its strong fertilization ability lasts only for 1 to 2 days. In other words, conception is only possible if sexual intercourse occurs within 1 to 2 days before or after a woman's ovulation. After a normal person ejaculates, sperm enters the uterine cavity and can survive for about 2 to 3 days, but its fertility can only be maintained for 1 to 2 days. Sperm that does not enter the uterine cavity and remains in the vagina will not survive for more than 1 day.

The eggs can mature and be released at any time. Although there are 300,000 to 600,000 primordial follicles in the ovaries that can produce eggs, only 400 to 500 follicles will mature and release eggs in a lifetime. In principle, only one ovary produces one egg per month. After being released, it quickly enters the fallopian tube to prepare for fertilization. If it does not meet sperm, it will lose the ability to conceive and die.
