Spermageddon: Could men be infertile by 2045?

Men are becoming increasingly less fertile. A study found that sperm counts in the West had dropped by nearly 60% in the past 40 years. According to that study, if sperm counts continue to decrease at this rate, they are set to reach zero by 2045. <br /><br />What is hijacking our fertility, and could we be on the brink of extinction? <br /><br />In this episode, host Dermot Murnaghan is joined by Shanna Swan, an environmental and reproductive epidemiologist who explains the causes of this reproductive crisis; Kate Brian from Fertility Network UK talks through the effects that infertility can have on people; and sperm donor Kyle Gordy describes the increase in demand for his services.
