If a man ejaculates into the water, it is highly unlikely that a woman will get pregnant
. There are many explanations as to why women
cannot get pregnant
just by swimming in a pool where sperm may be present. If ejaculation takes place in hot water (like a hot tub or Jacuzzi), or water filled with pool chemicals, bubbles, chlorine, or other substances, sperm would not be able to survive for more than a few seconds. Also, the water in a pool is too cold for sperm to live.
