Expert Q&A

Can too much vaginal acidity affect or kill sperm?
Keep in mind that the normal, healthy vaginal ecosystem is acidic, but sperm are killed by the acidity. That is why the semen that accompanies the sperm is alkaline. The semen transiently protects the sperm in the vagina until they can move safely past the cervical mucous into the uterus and tubes. Sperm left behind (usually because of poor mobility) are pretty much destroyed by the vaginal acidity in five minutes, so they have to be quick! In fact, the quickest sperm can be found in the tube within 90 seconds of being deposited in the vagina.
