What does the IVF success rate depend on?

With the advancement of medical technology, some couples who have difficulty conceiving can realize their dream of becoming parents through assisted reproductive methods. Among them, in vitro fertilization is a very common means of assisted reproductive technology. With the development of technology in recent years, the success rate of in vitro fertilization can be said to be getting higher and higher. Of course, there are also some failed cases. So what does the success rate of in vitro fertilization relate to? Let's take a look at this aspect.

What does the IVF success rate depend on?

1. Ability to obtain more high-quality eggs

As long as you can get high-quality eggs, you can cultivate high-quality embryos for transplantation. However, if there are more than 25 eggs or polycystic ovaries, the ovaries will be over-stimulated, and the body will also increase the burden accordingly. At this time, the body is not in the best state for conception, so you should go back to rest and adjust for a period of time before transplanting frozen embryos. The success rate will be improved.

2. The woman is under 35 years old

If the woman is over 35 years old or has a low ovarian reserve, the number of eggs retrieved will be relatively reduced, and there may be only two or three embryos that can be transplanted. The range of embryos to choose from will be smaller and the success rate will be lower. To increase the success rate, first of all, you should ensure that the woman is under 35 years old, has good physical fitness and no serious chronic diseases.

What else should we pay attention to in order to improve the success rate of IVF?

1. Chromosome screening. If one of the spouses has a chromosomal problem, then chromosome screening is necessary to increase the success rate of in vitro fertilization.

2. Ensure that your body is free of illness or pain. If a hysteroscopy is performed after egg retrieval, it will take more than a month after the surgery for the body to fully recover before the frozen embryos can be transplanted.
