The number of couples suffering from infertility is high and on the increase in China, and it is also a worldwide problem. Over the past 20 years, there have been two significant changes in the clinical practice of infertility: 1. In vitro fertilization (IVF) and other assisted reproduction techniques have provided greater possibilities for successful treatment of infertility, making the public aware of the possibility of successful infertility treatment, and therefore more infertility visits. 2. Increase in the number of infertility visits over the age of 35. In the United States, 20% of women have their first child after the age of 35, and women in our country are getting married and having children later. So is age related to fertility? The most classic research is on the fertility of Hutterites living in the U.S. states of Montana and Dakota, which border Canada. Among Hutterites, contraception is penalized, there are no restrictions on family size, and every family has equal rights. A study of such a healthy, stable, non-contraceptive group showed that the infertility rate was 2.4%, the mean age at last pregnancy was 40.9 years, and fertility declined with age. 11% of women stopped having children after age 34, 33% after age 40, and 87% after age 45. Therefore, women’s fertility is closely related to age, with the rise of age fertility decline, which shows that women should seize the golden age of their own fertility, do not miss the preservation of fertility! In modern society, the public is faced with tremendous pressure from school, life and work, and many people postpone marriage and childbearing for this reason. It is better not to exceed 35 years old, as age is too old, not only the eggs are easy to aging, the probability of embryonic dysplasia increases, and the fetus is easy to be affected by the teratogenic factors, meanwhile, the rate of congenital stupid children born is higher. It is recommended that women arrange their studies, work and life properly, and give birth to healthy babies at the optimal age for childbearing, so that the happiness index of the family will rise, and the future generations of our country will be stronger than the previous generation!
