Is it dangerous for a woman to become pregnant at the age of 50?

      One study found that people over the age of 50 female If you receive eggs from a young woman and get pregnant through in vitro fertilization, your risk of pregnancy complications is no higher than that of a young woman. Uterus The normal working time of the ovary is much longer than that of the ovary. As long as the method and conditions are appropriate, elderly pregnant women will not face higher pregnancy risks.

　　Over the past 20 years, the average age of U.S. women getting pregnant has been getting older and older, and there are even cases of pregnancy at age 60. Through in vitro fertilization using eggs donated by young women, even post-menopausal women can successfully conceive and give birth. A study published in the February issue of the American Journal of Perinatology examined 101 women aged 50 or older who had become pregnant using donated eggs from younger women. Research has found that the risks of pregnancy in this age group are similar to those faced by younger women.

　　One of the researchers, Mark Sauer of Columbia University Medical Center, said that women who get pregnant through in vitro fertilization have no problem giving birth despite being 50 years old or older. These women suffer from complications such as diabetes during pregnancy, or develop complications during pregnancy. premature birth The phenomenon of labor pain is no different from that of women under 42 who get pregnant through artificial insemination, but the chance of developing high blood pressure is slightly higher.

　　Sauer also pointed out that it is not easy to find pregnant women over the age of 50. It took 10 years to find the 101 women involved in the study. They are all well-educated and wealthy people who consciously adopt artificial insemination methods to get pregnant at an advanced age. However, in general, since the uterus and ovaries are two completely different organs, pregnancy and egg production are also two completely different situations. The uterus basically does not change with age. As long as the hormone levels are sufficient, the uterus of older women can be raised normally. fetus ； The ovaries are different. A 2009 study concluded that the age of 43 is a watershed for a woman to use her own eggs for in vitro fertilization. Although there are examples of natural pregnancy at older ages, they are extremely rare.
