Is it really as easy as some people think to have children at an advanced age? If “natural” doesn’t work, is “in vitro fertilization” sufficient? The best age to have a baby is between the ages of 23 and 30. The best age for women to have children is between 23 and 30 years old. The medical term for those who are over 35 years old is “advanced maternal age”, and from the perspective of eugenics, it is very unscientific to get pregnant at an advanced age. The first thing you need to do is to go to the hospital for the necessary physical examination before you can have a baby. The male partner needs to check: semen test, hepatitis, syphilis, AIDS and other infectious diseases. The female partner needs to check: routine blood, urine, liver and kidney function, blood sugar, six hepatitis tests, TORCH test, thyroid function test, pelvic ultrasound, liquid-based cytology and other tests. In addition, both men and women should start to quit smoking and alcohol at least three to six months before they are ready to get pregnant, so as not to affect conception and embryonic development. In addition, the lifestyle should be regular, combining work and rest, exercising properly, getting enough sleep every day, and making adequate nutritional preparations. At the same time, sexual life should also be regular. Learn to reduce stress and maintain a peaceful state of mind. Excessive stress, depression and anxiety can affect endocrine secretion and thus conception. Many couples of advanced age have the misconception that with IVF technology, they can postpone childbirth indefinitely. IVF is mainly suitable for couples with tubal infertility, unexplained infertility, endometriosis, ovulation abnormalities, severe oligospermia and chromosomal abnormalities in men, and for couples with serious hereditary disease risks and chromosomal abnormalities. The one condition of advanced age is by no means an indication for IVF. As a woman ages, the number of follicles in her ovaries decreases and the quality of oocytes decreases. Data show that the percentage of oocyte abnormalities is 50% for women older than 35 years old and 80% for women older than 40 years old. Moreover, the percentage of age-related infertility is gradually increasing and even IVF cannot fully compensate for this loss of fertility. Because of the low success rate of IVF in advanced age patients, it is often necessary to do several procedures before conception is possible. Therefore, regardless of the reason for IVF, the earlier the better.
