Hi my name is Amanda. Me and my wife are looking into having a child and we were wondering about something. We have our own friend that is willing to be our sperm donor. We wanted to know how long after he ejaculates in a cup how long do we have to use his sperm?
Hi, Thanks for writing to Chat Doctor. I hope you must have got your semen analysis twice or thrice in different laboratory and confirmed that count is low. After ejaculation into container within 30 mins it should be given to laboratory for processing.  If delayed sperms start dying. And the fluid part Chat Doctor.  It should be processed within 30 mins. Hope I have been helpful. Regards
