hi if you did get some of his penicillin the amount in sperm would only be very minute not enough to give you a problem. you need to think of the amount going around his body and the amount that would get into his sperm and take it from there. do hope this helps. good luck
does penicillin go in a mans semen sperm? . my fiance has been taking penicillin vk 500mg for three days and we forgot and made love; i have a sever reaction to penicillin should i be worried?
