More often than not when we think about fertility, we immediately start thinking about women. Yes, we are the ones who have menstrual cycles and get pregnant and grow babies, but if it wasn’t for male sperm pregnancy would never be possible. And if a couple is struggling to conceive, it’s about an even 50-50 split about whether it is a male or female cause.

In this episode, we’re talking about what makes up an individual sperm cell; how the male reproductive system works to maximise chances of fertilising a female egg and we’re also talking about sperm count – how this is actually measured, how it’s changed over the past 100 years and some advice for couples who are trying to conceive with potentially low sperm counts.
