Does IVF have requirements for parents' age?
IVF refers to the process that fertilized eggs are cultured in vitro and implanted into the mother's uterus through artificial assisted reproductive technology (ART) to achieve pregnancy and delivery. With the increasing demand for the time and method of childbearing, IVF has gradually become a choice to solve the problem of infertility. However, due to the particularity of fertility technology, IVF also has certain requirements on the age of parents.
1. Female age requirements
Women's fertility will gradually decline with age. Generally speaking, women are more likely to have children before the age of 30, while those aged 35 and above, especially after the age of 40, are prone to infertility. Therefore, most IVF centers recommend that women have IVF before the age of 35.
First, the quality of female eggs is one of the key factors that determine the success rate of pregnancy. With the growth of age, the quality and quantity of eggs will gradually decline, which will easily lead to poor quality or abnormal development of fertilized eggs, thus affecting the success rate of pregnancy.
Secondly, in the process of in vitro fertilization and embryo transfer, women's uterine environment also has a certain impact on the success rate of pregnancy. With the increase of age, the thickness and function of female endometrium will also decline, thus reducing the chances of embryo implantation.
2. Male age requirements
Compared with women, the age of men has less influence on the success rate of IVF. However, male fertility will also decline with age. Some studies have found that after the age of 35, the quality and quantity of sperm will decrease, and the proportion of deformed sperm will increase.
Increasing male age may also increase the risk of chromosomal abnormalities and genetic defects. These abnormalities often lead to poor development of fertilized eggs or spontaneous abortion of early embryos.
3. Hospital restrictions on age
The age limit of IVF varies with hospitals and national policies. Generally speaking, the hospital will make appropriate plans based on the results of various examinations and the professional judgment of doctors. If the age of women or men exceeds the age limit of the hospital, they may be recommended to use donated eggs or sperm for IVF.
In addition, different hospitals may have different suggestions and requirements for age. Some hospitals may pay more attention to women's age, while others may pay more attention to men's sperm quality. Therefore, selecting the right hospital and professional team is crucial to the success of IVF.
4. Summary
In general, IVF has certain requirements for parents' age. The age of women is an important factor affecting the success rate of IVF. It is recommended that treatment be carried out before the age of 35. Although the influence of male age is small, its influence on sperm quality and genetic defects cannot be ignored. Different hospitals may have different age restrictions, so it is important to select appropriate hospitals and professional teams to improve the success rate of IVF.
Finally, regardless of age, we hope that every couple who want to have children can find their own solutions to achieve the happiness and integrity of their families.
