I've read that watery semen isn't a great sign when it comes to male fertility. My partner and I are having some trouble conceiving and I've noticed this might be a thing for us. Is it true? What can we do?


The cloudiness of semen is affected by how often you ejaculate, how hydrated you are, whether you’ve been drinking alcohol and whether you’re looking at your ejaculate or vaginal discharge after sex.

The concentration of sperm is what makes the semen cloudy and thick, so if your ejaculate is watery it is possible that you have a low sperm count. This doesn’t mean you’re infertile (so precautions to prevent pregnancy still need to be taken for couples that don’t want to get pregnant). Your GP can arrange for you to have your semen tested but you need to wait at least two days after your last ejaculation before you produce the specimen.
