Question 1

would washing hands with soap and pretty hot water along with hydrogen peroxide kill any sperm on hand?

Accepted Answer

I wouldn't go so far: as to recommend this (hydrogen peroxide is not completely benign if used frequently on the hands), but here is a reference that suggests spermatoa are fairly susceptible to H2O2.  I would expect soap and water to do the trick.  http://www.ncbi.nlm.nih.gov/pubmed/12384208

Question 2

can applying hand sanitizer (70% alcohol based) and wiping with sanitizing towels works as well to kill sperm in hands as washing them with soap and water?

Accepted Answer

: Yes they are fragile. They like body temperature &amp; the moisture/mucus lining the inside of the female genital tract. Once  they are exposed to drying/water/sanitizer/soaps they become incapacitated quickly.

Question 3

does water kill sperm due to osmotic shock?

Accepted Answer

Osmotic shock: Sperm could not live in water for a prolonged period of time. But having sex under water does not prevent pregnancy.

Question 4

will hot water and soap kill sperm?  how long can sperm live?

Accepted Answer

Hot H2O kills sperm.: Hi Karina 0626
Yes, sperm cells are quite delicate and need to be ejaculated IN the vagina, as close to the cervical os (opening) as possible for them to work. When guys do a sperm test and ejaculate into a container, there is a large amount of the sperm that are not motile. Anything below 50% motility is not normal and below 25% could be problematic. Sperm on your clothing will not make you preg.

Question 5

which of the following can kill sperm?
a.water
b.soap
c.ethanol?

Accepted Answer

: Sperm does not survive long outside of biological conditions, so all the things mentioned will kill sperm. They should not be used vaginally, and ethanol, would irritate the penile head. Soap and water can be used to wash yourself after sex. It might be wise for you and your partner to get sex education regarding pregnancy avoidance techniques to avoid unexpected surprises.

Question 6

i got sperm on my finger, and washed it off almost immediately with just water, does this kill sperm?

Accepted Answer

: Sperms are quite weak outside of their usual environment or in the vaginal/uterus areas. They die off very quickly in water --they swell up. They also die off quickly when exposed to air/drying conditions. So, washing off your hands certainly did the job...especially if you washed it well. Good luck

Question 7

will cold tap water (with or without soap) very quickly or even instantly kill sperm, owing to osmotic shock?

Accepted Answer

Spermicide ?: Tap water is definitely going to create an osmotic deficit when contacting living cells, but it is not sufficient to kill sperm effectively, so pregnancy is always a possibility. 
The only way to resolve this is to wait until the receiver of the sperm has a period.  Obtain a serum (HCG) pregnancy test if she is "late".

Question 8

i know a towel and handsoap without water. is enough to kill sperm but would it clean it off the penis as well? does killing mean that its cleaned off? i read somewhere that it was enough but wanted to make sure? like the penis is clean right?

Accepted Answer

: Not sure why you're worried but it appears you are perfectly clean.

Question 9

if i wash sperm off my hands with water, can the sperms die ? and can exposed air kill sperm ?

Accepted Answer

Eventually: Sperm don't last long outside the warm moist environment of the male &amp;female genital tract. When they dry out, they are no linger effective. When washed/diluted with soap &amp; water they  can no longer function.

Question 10

if you wash your hands with water only will it kill any sperm on your hands or atleast can wash it off completely?

Accepted Answer

: Thorough washing with water only will remove the sperm or render in capable of impregnating a woman. However, it will not get rid of all microbial pathogens and you may still transmit STDs.
