Nowadays, with the effectiveness of IVF technology in the treatment of infertility, this technology has become the choice of more and more infertile families, but due to the particularity of IVF technology, the technology has higher requirements for the age and physical fitness of IVF patients, therefore, not everyone can do IVF fertility, nor can it guarantee that everyone can succeed in doing IVF once.
Hengjian Overseas pointed out that experts introduced that IVF is a series of technologies that use artificial methods to retrieve sperm and eggs, cultivate embryos in the laboratory, and then transfer embryos into women's uterus to help infertile couples have children.
However, IVF technology is high-end and complex, in addition to its own physical conditions, there are many factors that affect the success rate of IVF clinical treatment, such as patient choice, clinical treatment methods, laboratory technology, doctor technology and hospital strength.
Hengjian Overseas said that the common factors that affect the success rate of IVF are usually the following:
1. Age factor
Women have the optimal age to have children: 25-35 years old. Whether it is natural birth or IVF during a woman's fertility process, age affects the success of pregnancy. During IVF, the older the woman, the worse the egg quality. After the age of 35, the quality of the eggs in women begins to age, and the risk of chromosomal variation increases. As women age, their physical function gradually weakens, and the miscarriage rate increases accordingly.
2. Embryo quality
Embryo quality is determined by sperm and eggs. The quality of the embryo is a key factor related to the success rate of IVF, and high-quality embryos are easy to succeed, and inferior embryos have a high failure rate. The above introduction can be seen that age affects egg quality, and female ovarian function also affects egg quality. Sperm quality is affected by the man's habits and living environment.
3. Uterine environment
The uterus is the place where the embryo implants and develops, and it is the soil where the embryo survives, and the fertile soil can affect the growth of seeds. If the endometrium is thick enough, the blood flow is abundant, and the cells divide well, it will increase the implantation rate of the embryo. At the same time, if you have endometrial diseases, such as endometritis, endometriosis, endometrial cancer, etc., it will affect the implantation of the embryo and reduce the success rate of IVF.
4. Influence of infertility factors
Women with infertility due to some diseases, such as uterine malformations, endometriosis, egg abnormalities or oligospermia, weak sperm, etc., will affect the success rate of test tubes, resulting in a decline in the success rate of test tubes. In addition, if both husband and wife or one of them has chromosomal abnormalities, it will affect the success rate of doing test tubes, and the failure rate and miscarriage rate of chromosomal abnormal couples are significantly higher than those of normal couples.
5. Effect of hydrosalpinx
Hydrosalpinx can cause tubal inflammation and kill embryos, and the entry of hydrospinning into the uterine cavity will destroy the endometrial environment of women, affecting the success rate of embryo transfer and embryo implantation rate. According to clinical statistics, the pregnancy rate of patients with hydrosalpinx without surgery is only about 25%, while the pregnancy rate of patients who have undergone tubal surgery can reach more than 50%. Therefore, women with hydrosalpinx should have their hydrosalpinx tubes removed before performing IVF.
