New research by Australian fertility experts has shown that IVF success rates drop as men age, debunking the myth that only women experience declining fertility as they get older.
The new study by researchers from Monash University and Monash IVF[1]found that in couples with unexplained infertility, increasing male age is associated with falling rates of live birth, clinical pregnancy and embryo implantation, while the miscarriage rates increase.
The male study participants' chance of live birth decreased by 4.1 per cent with each year of increased age, with outcomes significantly worse for men in their fifties.
In the study, the men's chance of conceiving halved from the age of 50, compared to those under 40.
