Age requirements for IVF infants
In vitro fertilization is a reproductive method that combines sperm and eggs in the laboratory, cultivates them into embryos, and then transfers the embryos back to the mother's womb for pregnancy. The age requirement of IVF is based on the medical consideration of the safety and success rate of mother and embryo. The following is a detailed description of embryo quality, uterine health, pregnancy complications and postpartum health from the age.
1. Embryo quality
For IVF, the quality of embryo is one of the key factors affecting the success rate. The increasing age of women will lead to the decline of egg quality. Therefore, doctors usually recommend women under 35 years old to have IVF to ensure the quality of eggs. In addition, with the growth of age, women's endocrine function changes, which may lead to ovarian dysfunction, which is not conducive to follicular development and embryo formation. Therefore, the success rate of IVF for women over 35 years old may be reduced.
In addition, the age of men also affects the quality of embryos. The old age of men may lead to the decline of sperm quality. Research shows that over 40 years of age, the morphology and motility of men's sperm will decline, thus affecting the quality of embryos.
Therefore, the age requirement for IVF is below 35 years for women and 40 years for men.
2. Uterine health
The health of the uterus is critical to the success of IVF. The increase of age will cause changes in the endometrium, such as decreased thickness, decreased blood flow, etc. These factors will affect the implantation and growth of embryos. In addition, the aging of uterine fascia will also affect the contractile function of the uterus, increasing the risk of premature delivery.
Therefore, doctors usually recommend that women carry out IVF at the age of good uterine health, and the best age is below 45 years old.
3. Pregnancy complications
With the growth of age, women are prone to some pregnancy complications, such as hypertension, diabetes, abortion, etc. These diseases will affect the safety of IVF and the health of mothers. Therefore, when choosing IVF, doctors will comprehensively consider women's physical condition and age to assess the risk of pregnancy.
Generally speaking, women under 40 years of age have a lower risk of pregnancy complications and are suitable for IVF.
4. Postnatal health
The postpartum recovery of IVF is very important for women's physical and mental health. Age increase will lead to women's weakened physical function, slow recovery after childbirth, and prone to postpartum depression and other problems.
Therefore, in order to ensure postpartum health, doctors usually advise women to carry out IVF under the age of 35.
summary
In conclusion, IVF has certain requirements for age. In view of embryo quality, uterus health, pregnancy complications, postpartum health and other aspects, generally speaking, the best age for women is below 35 years old, and the best age for men is below 40 years old. At the same time, doctors also need to make a comprehensive assessment based on women's physical condition, pregnancy risk and other factors to ensure the safety and success rate of IVF.
