You can be sure that no woman has sperm because only men has that.
Most likely if a man's penis has been in or around a vagina there is sperm inside.
a sperm is A male gamete or reproductive cell or in a way that we all can understand...the cell thing from a man's penis that is in cum. when the cum goes into the vagina it releases sperm cells causing pregnancy
From what I know, all the guys have to do is release the sperm inside a women and it goes into their womb.
Short Answer:If the sperm is from a healthy individual there should be no Ill effects from it.More than you really wanted to know!Sperm is the cause of the Human body, we are made when a man & a woman have sex & the male ejaculates sperm inside a woman & the egg is fertilized, so with out the sperm there would be no you or me!Sperm is natural and a part of life. if you get it on your skin, it isn't an irritant or corrosive. If consumed it contains proteins & sugars & no bad effect.

To know if conception occured you have to wait until the woman misses her period and takes a pregnancy test to confirm.
You would need to undergo tests to know for sure - but most men have no problems in that regard. Tests would count the average number of sperm present - which is important - and wouldsee how healthy they are.
