Can dead sperm be used in test tubes?

Dead sperm is not a condition where normal sperm cannot survive as everyone thinks, but refers to the absence of normal active sperm.

When sperm is not normally active, various problems will occur, resulting in the inability to combine with the egg to form a fertilized egg.

This is a condition that leads to male infertility. If it is found that the infertility is caused by male dead sperm in the absence of pregnancy, it is also important to understand the relevant content of dead sperm in addition to actively cooperating with treatment.

Within 1 hour after the semen is discharged from the body, under normal circumstances, more than 70% of the surviving sperm should be present. If the dead sperm exceeds 40%, then the male may have a very serious case of dead sperm.

The survival time of sperm should be kept at about 6 hours. If the sperm survival rate is less than 20% at this time or there are no viable sperm within 6 hours, it is likely to cause infertility.

It is worth noting that when the sperm is discharged from the body, it does not mean that it is completely exposed.

Necrozoospermia can be divided into two situations: true sperm death or false sperm death. This condition can be diagnosed by eosin, aniline blue staining or hypotonic swelling.

If the sperm are all colored after eosin staining, it means that the sperm are really dead. In this case, IVF is not recommended. Of course, if the couple is well prepared, sperm donation IVF can be performed.

If the sperm does not move due to ciliary dysfunction, it is pseudodeath. In this case, in vitro fertilization is possible.

Before infertile couples undergo in vitro fertilization surgery, they need to undergo a series of examinations. Among them, including sperm examination.

If the male's test results show that the male's sperm density is between 10 million and 20 million, sperm survival is about 20%, and normal-shaped sperm can exceed 4%, then IVF can be performed.

If the sperm is falsely dead, in vitro fertilization can be performed. In most cases, second-generation IVF is recommended. However, the specific implementation still needs to be carried out according to the individual situation.

If the sperm is really dead, sperm donation IVF can be performed.

In order to ensure the activity of sperm, sperm washing and other methods will also be used to eliminate a batch of sperm with insufficient activity.
