The best age for IVF, age requirement is very important

In vitro fertilization is the process of cultivating fertilized eggs in vitro and then transplanting them into the woman's uterus. It brings hope to infertile families, but there is an age limit for in vitro fertilization. Being too old will increase the chances of spontaneous abortion and fetal malformations after conception.

1. Age requirements: Both men and women who want to undergo in vitro fertilization must be physically and mentally healthy, without hereditary diseases, the woman's age is generally not more than 40 years old, and the man's age is not more than 55 years old. Because the woman is too old, the miscarriage rate after natural conception is high, the possibility of fetal malformations is also greater than that of younger women, and the complications during pregnancy increase, which leads to a lower success rate of in vitro fertilization surgery.

2. People who are suitable for in vitro fertilization: 1. Severe fallopian tube diseases, such as fallopian tube obstruction, hydrops, fallopian tube dysplasia, bilateral fallopian tube removal, etc. 2. Patients with endometriosis who have not responded to treatment. 3. Immune infertility, such as the presence of anti-sperm antibodies, anti-endometrial antibodies, etc. 4. Male factors, namely oligospermia, asthenospermia and teratospermia. 5. Those whose infertility treatment is ineffective. 6. Patients with genetic diseases or failed hysteroscopy and laparoscopy surgeries.

3. People who are not suitable for IVF: 1. Any party providing the egg or sperm suffers from acute infection of the reproductive or urinary system or sexually transmitted diseases. 2. Either party providing the egg or sperm has bad habits such as alcoholism or drug abuse. 3. Either party providing the egg or sperm has been exposed to teratogenic amounts of radiation, poisons, or drugs and is under the effects of these drugs. 4. The woman suffers from a serious genetic disease, serious physical disease, mental or psychological disorder that makes her unsuitable for childbearing. 5. The woman’s uterus is not capable of pregnancy or she has a serious physical illness and cannot sustain pregnancy.
