Life of Sperm

[debpac]

I am confused about something hope someone can help! I have read so many different articles on this subject, that I don’t know which is correct. I have read that sperm can survive for up to 7 days, but that it can only fertilize for 3 days. Does anyone know????? ❓

According to what I know, sperm can survive for approximately 2-5 days in the female body. but in the open-air, it just survive for a few hours.

It is all depends on the medium where they are. If the condition is suitable (temperature, pH, nutrients, etc.) they could live longer. Female reproductive system is acidic, sperms need basic pH (8 or more). External environment (open air) is impossible. However if we culture them in a proper medium, they able to live well, but still as no longer as in natural medium 🙂

The survival of spermatozoa, or sperm, depends on the conditions under which they are being held:

Sperm exposed to air, deposited on clothing, bed linens, or toilet seats, for example, dry out very quickly and die, usually within minutes after ejaculation.
A sperm sample collected in a sterile container at body temperature may remain alive for several hours, but the sperms’ fertilizing capability drops dramatically within 60 minutes after ejaculation.
Sperm deposited inside the vagina usually die within 20-30 minutes after ejaculation.
Sperm that move from the vagina into the uterus can survive longer. Studies have shown that conception is possible up to five to six days after intercourse. So it is possible for some sperm to survive that long in the uterus, usually in the cervical mucus or the fallopian tubes. But that is not typical. Most sperm die in the uterus within 24-48 hours after ejaculation, and the more time has passed after ejaculation, the less likely is the fertilization of the egg.
In excellent laboratory conditions and in a nutrient medium they can remain alive for up to seven days.

I feel sorry for sperm… They live for like three days and 99.9999% of them die for nothing…
