Giving birth at an older age is actually bad for both the baby and the mother. With the increase of age, the quality of sperm eggs decreases, which not only reduces the probability of successful pregnancy, but also increases the chromosome abnormality rate, abortion rate and fetal malformation rate of fertilized eggs.

For example, Down's syndrome, which should be checked in pregnancy test, is a disease with three abnormal chromosomes, and its incidence rate is closely related to the mother's age.

Women rarely get sick after 35 years old, and the incidence rate increases obviously after 35 years old. After the age of 45, the incidence rate can reach 1/50.

The risk of giving birth at an older age is high. How to prepare for pregnancy and eugenics?

1 Pre-pregnancy examination is very important.

Older couples should have a complete pre-pregnancy examination, including general physical examination for women, reproductive and genetic examination, routine semen examination, sperm morphological analysis and chromosome examination for men.

2 measure ovulation and try to hit it with one blow.

Older couples can monitor ovulation by using ovulation test paper combined with basic temperature measurement, and lock the ovulation time at 4-7 hours, so that women's reproductive tract has enough "vitality" sperm to share the same room, waiting for the emergence of eggs, so that the freshest eggs can be combined with the strongest sperm, thus improving the pregnancy rate.

3. Appropriate nutrition supplement

Women can properly supplement phytoestrogens, vitamin E and coenzyme Q 10, which is beneficial to maintaining ovarian function and follicular development. Men can pay attention to supplement zinc and selenium to make vitamin E, improve spermatogenic function and reduce sperm DNA damage.
