There is often a saying about [the best age for childbearing].
The basis for this statement is that with the increase of age, the total number of women’s eggs gradually decreases, the eggs also gradually age, and the percentage of eggs with normal genes gradually decreases.
At the same time, with the increase of age, the fertility rate of women will decrease, the abortion rate will increase, and the probability of birth defects such as Down’s syndrome will also increase.
In theory, women can become pregnant and have children when their menstrual cramps enter the stage of sexual maturity.
In the old society, girls began to marry and have children around the age of 13-15. However, girls at puberty are not yet mature physically and mentally and it is not appropriate to have children.

From a physiological point of view, it is best for women to have children around the age of 20: it is easy to get pregnant, give birth quickly and smoothly, recover quickly after delivery, and have fewer birth defects. Having children at this age is really like bearing fruit on a tree, falling off when ripe.
However, the psychological age of women at this age is often not mature enough, they may not have completed their studies and have no stable job, and it is not appropriate to have children so early.
On a comprehensive balance, the more suitable age for giving birth is about 25-28 years old. If it is for career development, it is OK to postpone it for a few more years, but try not to postpone it until after 35 years old.
During the intrauterine period, all the eggs of the female fetus have completed their first meiosis, so they are born with all the eggs in her life. Her birthday is the [date of birth] of all her eggs.
Like food, eggs have a shelf life. The quality of eggs that have been manufactured for 20 years is different from that of eggs that have been manufactured for 35 years. Eggs that have been manufactured for 45 years have basically passed their shelf life.
Pregnant in their twenties
Women in their twenties have normal ovarian function and more healthy eggs in their ovaries, so they are more likely to get pregnant. Their chances of getting pregnant every month are about 20-25%. Women in this age group should seek the help of reproductive experts if they still fail after 12 months of active attempts to get pregnant.
The rate of spontaneous abortion after pregnancy is only 5-10% for women in their twenties, and the incidence rate of Down’s syndrome is about 1/1200.
Pregnant in early 30s
After being over 30 years old, women’s fertility will decline, and their monthly pregnancy rate is about 15%. If women of this age group fail after actively trying to get pregnant for 9 months, they should seek the help of reproductive experts.
The probability of miscarriage after pregnancy for 30-year-old women is about 20%, and the risk of Down’s syndrome is about 1/952.
Pregnant over 35 years old
Women over 35 will face many problems if they want to become pregnant.
Women over the age of 35 have a significantly lower monthly pregnancy rate, only about 10%. Women of this age group should seek the help of reproductive experts if they still fail after actively trying to conceive for 6 months.
After 35-year-old women become pregnant, the abortion rate is 25%, and the risk of Down’s syndrome becomes about 1/378.
To sum up:
If you want to have a baby, you have to do it early. It’s really good to be in your twenties.
