About this episode

The episode discusses the concept of the biological clock in relation to fertility for both women and men, featuring insights from Dr Theresa Larkin.

For years women and people with eggs have been told they have a ‘biological clock’ when it comes to their fertility, but how true is that really? And does sperm have the same ‘clock’? In this ep, Dee chats to associate professor Dr Theresa Larkin on the latest research on infertility and why it’s been so gendered. SHOW NOTES: Yes, men have a biological clock too. But it’s not just age that affects male fertility What’s the difference between sperm and semen? And can pre-ejaculate get you pregnant?
