Once they are inside the vagina there is only one thing she can do and that is to take the morning after pill. If it's on your hand wash it off or it will die when dry. Someone wrote urine kills sperm and that is a myth.
Warm water does not help sperm. If it is cool enough it will have no effect, but if it is warm enough it can damage the sperm in the testicles. Sperm are pretty sensitive to increased temperatures, and this is why they reside in the scrotum. The job of the scrotum is to keep the testicles a few degrees cooler than the rest of the body.
Use warm, soapy water (or shampoo).
Sperm cells can be killed instantly upon contact with soap or soapy water. The chemicals in soap disrupt the sperm cell membrane, leading to their rapid destruction.
Yes, but it is better to use soap and warm water
If the water is only warm, quite a while because sperm prefer an alkaline[soap] environment.
doubtable, because heat kills the "swimmers" in the sperm. It is noted mean shouldn't wear regular briefs because the heat against the testicles can greatly reduce their sperm count. If he touched the warm water with it, then fingered you the heat more than likely killed the impregnating swimmers.
Not in my experience! It's very sticky. Even with warm water and soap, it can take a really good latering to get it off the skin. I can't comment on it's potency after watering it down with cold or warm water; just the clean up effort. Yes, soap and water will rinse it away. Water alone will also do the job. I hope you're asking about sperm on your skin and not inside of you - because water will not wash enough sperm out of you to be effective.
Sperm whales -like all whales - are warm blooded
Generally, no. Germs are best killed by very warm or hot water.
Yes, some whale species live in warm water environments. For example, species like humpback whales, Bryde's whales, and sperm whales can be found in tropical and subtropical regions where the water is warm. These whales have adaptations to thrive in these environments.
No, it will not. The sperm are housed outside of the body because it is too warm inside. If it becomes too warm, the sperm will die. If it is way too cold, it will die as well.
Sperm can be killed by spermicidal agents, such as nonoxynol-9.
