How long can sperm survive in the air?

Patient's question:

In the air... the longest

Doctor's answer:

Normal sperm motility (37°C) should last for more than 4 to 8 hours.
? Survival days of active sperm in the vagina? 0.5 days.
? Survival time of active sperm in the cervix? 2 to 8 days.
? Survival days of active sperm in the uterus and fallopian tubes? 2 to 2.5 days.
? However, the duration of sperm activity is also related to whether the environment of the female's vagina, cervix, uterus, and fallopian tubes is normal.
