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? That will remove any doubt.
