Hi Dr. Yvonne, Does water act like a spermicide if you have sex in it? Stevie

Water is not a spermicide. While chlorine makes for a hostile environment for sperm (and latex), it will not kill sperm right away. While men who spend a lot of time in hot tubs tend to have lower sperm counts, the hot water cannot be relied upon as birth control. The general rule is - in or out of water - anytime semen is emitted in the vagina or on the vulva, there is the chance of pregnancy.
