Older fathers linked to ‘significantly’ higher IVF miscarriage risk
Father’s age may impact the success of an IVF pregnancy
- A new international study indicates that a father's age plays a crucial and independent role in fertility outcomes, particularly in IVF.
- The research found that IVF cycles involving male partners over the age of 45 carry significantly increased miscarriage risks and lower live birth rates.
- The study analysed 1,712 IVF cases between 2019 and 2023 in Italy and Spain, using fresh donor oocytes from younger women.
- For older prospective fathers, the miscarriage rate reached 23.8 per cent compared to 16.3 per cent in the younger paternal age group, with live birth rates also lower.
- The findings challenge the traditional focus solely on maternal age and underscore the need for fertility clinics to inform male patients about the impact of their age on fertility potential.
