What is the survival rate of sperm in air?

There are many factors that affect men's sperm survival rate, such as sexual life, estrogen in the body, and men's prostaglandin levels. In short, if men find that their sperm survival rate is low through examination, they should find out the cause and solve it accordingly. Improving sperm survival rate is an effective measure to treat infertility. So what is the survival rate of men's sperm in the air?

How long can sperm survive in air?

Sperm is the most important substance in men's reproductive organs, and its main function is to carry the great mission of passing on the family line. The survival of sperm is also limited by time. Its survival time will be different in different environments. So let’s find out today, how long can sperm survive in the air?

After a man ejaculates, if the sperm stays in the vagina for too long, the acidic environment in the vagina will shorten the survival time of the sperm. Therefore, sperm can generally not survive outside the body for more than 24 hours. If the sperm is in the air, it will generally die within two hours. Its usual survival time is 15 to 30 minutes.

Sperm is a substance produced by the male reproductive organs, so its initial living space is of course in the male body. If sperm is in the male reproductive tract, it can survive for several weeks. But after a man ejaculates, semen can only survive in his semen for 24 to 72 hours at most. Of course, if the temperature is low enough at this time, semen can be stored for several weeks. If semen is frozen in liquid nitrogen, it can be stored for a long time.

Under normal circumstances, when semen is discharged from the body, the survival rate of sperm should be more than 70% within one hour. If the dead sperm exceeds 40%, it will affect conception. The sperm survival time should be maintained at more than 20% for 6 hours. If there are no viable sperm within 6 hours, it may cause infertility. Dead sperm also lose their activity and fertilization ability, which can cause infertility. Therefore, it is very necessary to understand the sperm survival time. This is directly related to male fertility.

Of course, through the above understanding, we can already understand that sperm generally survives a very short time in the air, in fact, not even a few minutes. The sperm will lose its activity and will no longer be able to conceive. Young men and women nowadays are always concerned about whether sperm living in the air will cause pregnancy when it enters the vagina again. In fact, this possibility is basically non-existent.
