Q: Twelve years ago my husband had his right testicle removed following a sport-related accident when he was 14 years old. I am 24 years old and we have been TTC for two months. I am not worried yet, but can having only one testicle affect a man's fertility?
A: It's unlikely that having one testicle removed can reduce fertility, because the remaining testicle usually takes over the sperm production. But why not make completely sure and test his ejaculate? A semen analysis will remove any doubt.
