Yes but it is ineffective as a contraceptive. Alcohol will kill any sperm out in the open, or in liquids, but if you have unprotected sex and expect using alcohol as a contraceptive afterward, that is a very uneducated idea. It would most likely burn and cause discomfort, and won't kill sperm already past the cervix.
Absolutely - but don't try to use it as a contraceptive. It's too voltile (evaporates too quickly) and isn;t good for the mucous membranes.
Because male sperms are alot more fragile than femal sperms
Not well enough to protect against pregnancy - no.
Alcohol does not kill brain cells.
Dose tadalafil tablets /dapoxetine hydrochloride tablets kill the sperms?
No, though sperm formation benefit from the lower temperature in the testes, increased temperature will not kill them.
Alcohol does not kill pubic lice. They must be killed with insecticide.
You be better off with someone like a condom, the pill etc. Salt can kill slugs though (and its not very nice when they die)!
Absolutely not! You can get pregnant and also give the guy the yeast infection.
No
Yes, it can kill a plant within weeks. Do no try to water a plant with rubbing alcohol unless you expect to kill it.
Rubbing alcohol will kill just about anything it comes in contact with. Apply liberally.
