Question

How long does sperm lasts in the uterus?

Answer 1

I believe it can survive for up to 72 hours...  

Answer 2

up to about 5 days, depending on the conditions of your v****a.

Answer 3

The life span of sperm after they're ejaculated depends on the environmental conditions. Sperm ejaculated into a woman's v****a remain alive in the mucus of the cervix and are able to fertilize an egg for three to five days. Sperm ejaculated outside the body usually live only a few hours.

Answer 4

I was told by my doctor that it can live inside you for up to 6 days and if I missed a pill I would need to use other protection for that long.
