How many eggs does a woman lay in her lifetime?

Although they are women, many people still do not know their reproductive status. How many eggs does a woman produce in her lifetime?

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

Women ovulate regularly every month, but how many eggs will be released in a lifetime? Let's do the math!

Women go through two growth stages from birth to old age, namely infancy, adolescence, and middle-aged and old age, and one decline stage. Female ovulation is when the female organ begins to grow and develop during the second menstrual period, which is about 13 years old. Usually, one egg is released during each menstrual period. In special circumstances, 2 or more eggs may be released, which is quite rare. The menstrual cycle is generally 28 days, but can be longer or shorter. When women are around 50 years old, their female organs gradually decline, the uterus and ovaries stop ovulating, and menopause begins. There are about 500 ovulation periods in a lifetime. There are hundreds of millions of eggs in the ovaries, and there is almost no chance for them to be expelled and die inside. The better ones will be successfully excreted and have the chance to combine with sperm to create new life.

According to scientific observations and various statistical analyses, a woman produces 400-500 perfect eggs in her lifetime. Normal women usually release one egg cell in one menstrual cycle, and some women release two eggs during menstruation. Normal female children have their first menstruation at the age of twelve or thirteen, and reach menopause when they are nearly fifty years old. I have my menstrual period every month, and I usually release one egg each time, sometimes two. That's about 12 a year, or about 400 in a lifetime. In other words, a woman's ovulation period lasts about 30 years. With the end of ovulation and the arrival of menopause, women will enter the elderly stage.

2. How long can a woman's egg survive in her body?

A normal growing woman ovulates once a month, which is approximately 12-16 days before the next menstruation. The fertilization ability of the egg is strongest within 6 hours after being released from the ovary, and can maintain the fertilization ability for about 30 hours. After that, the egg begins to change, and the fertilization ability quickly weakens and disappears. Although sperm ejaculated into the female reproductive system can survive for up to 4 to 5 days, it only has a strong fertilization ability for 1 to 2 days. In other words, pregnancy is only possible if you have sex within 1 to 2 days before and after the female ovulation period. When a normal man ejaculates, the sperm can survive in the uterus for about 2 to 3 days, but its reproductive function can only be maintained for 1 to 2 days. Male sperm that does not enter the uterus and remains in the female vagina will not survive for more than 1 day.

The egg cell can be matured and released at any time. Although there are 300,000 to 600,000 primordial eggs in the ovaries that can produce egg cells, only 400 to 500 of them can fully develop and release egg cells in a lifetime. Under normal circumstances, only one egg cell can be produced in one ovary each month. After being released, it quickly enters the fallopian tubes to prepare for fertilization. If no sperm is met, the woman will lose the ability to get pregnant and even die.
