how long should i wait to build up sperm
Â· just now. Report Abuse. You should give the sperm at least 24 hours to re-build. However during ovulation if you are worried that you will miss it then have sex everyday at the same time then that gives the sperm 24 hours.Remember it takes only 1 swimmer to get the egg. Having sex every second day is sufficient though.lso to much sperm can just kill eachothers off and everyday can also give you a lower count/ Me and my husband made a schedual and had sex every other night. I know it sounds awful to have a schedual but It WORKED =))) ..........
