No entry outside the body during ovulation

First, we need to understand what IVF is. In vitro fertilization refers to the direct injection of sperm into a woman's body through a sexual instrument outside the woman's body in order to fertilize the woman's body. While this technique can be very useful in certain situations, it also comes with some risks. One of these is failure of in vitro fertilization.

So why does IVF fail? There are a few factors that can cause IVF to fail. One of the most common causes is insufficient sperm quantity and quality. Although a man releases a high amount of sperm each time, only a small number of them can enter a woman's body and implant. If the quantity and quality of these sperm are insufficient, fertilization may fail even if IVF is performed.

Another factor that may cause IVF to fail is that the woman has an insufficient number of eggs. The number of eggs a woman releases each month is limited, and if the number is insufficient, fertilization may fail even if in vitro fertilization is performed.

In addition, a woman's physical condition may also affect the success of IVF. For example, infection or inflammation in a woman's reproductive organs may reduce the number and quality of eggs she releases, causing IVF to fail.

Finally, there are other factors that may cause IVF to fail. For example, a woman may have experienced certain health problems prior to IVF, which may have affected her fertility, causing fertilization to fail.

Although in vitro fertilization can be very useful in certain situations, there are some risks. If you plan to use IVF, make sure you understand all the risks and take the necessary steps to protect your interests. In addition, for couples who want to have a child, it is best to consider natural pregnancy methods to ensure the health and welfare of the child.
