Male infertility common but largely idiopathic, report finds

An annual report on assisted reproduction has, for the first time, listed causes of male infertility

Male infertility is a factor in nearly one-third of Australasian assisted reproductive technology cycles, but the cause in most cases is unknown, epidemiologists say. 

A new report captures data on every assisted reproductive technology (ART) treatment cycle performed in Australia and New Zealand in 2020, including, in a world first, detailed information where the causes of male infertility were known.
