Male infertility is involved in one in three rounds of IVF in 2020, and most of those men don’t know what affected their potency.
About 20% of IVF rounds in 2020 were due to infertile men and another 11.2% were due to both men and women being infertile within a couple, Australia and New Zealand Reproductive 2020 Ancillary technology reports are from the University of New South. Wales (UNSW) found.
Looking for an underlying cause, three-quarters of infertile men remained undiagnosed.
“[It]reflects a lack of understanding of why semen is of poor quality,” said Luke Rombouts, president of the Fertility Association of Australia and New Zealand.
Another 7% resulted from a previous vasectomy, and 2.4% converted to IVF after receiving cancer treatment.
Research on pregnancy used to focus only on women, Rombouts said, but men played an equal role in pregnancy.
As more data has been gathered about the causes of male infertility, scientists have become more likely to understand its effects.
The results indicate that more research and education are needed, and genetic studies are likely to reveal risk factors for infertility.
Overall, 96,000 IVF cycles were performed in Australia and New Zealand in 2020, resulting in 18,462 newborns.
This is up 7.6% from 2019 and means that 1 in 18 babies born in Australia in 2020 were conceived via IVF.
Professor Georgina Chambers, a public health researcher at the University of New South Wales, said the COVID-19 pandemic may have impacted birth numbers as health restrictions restricted in vitro fertilization in some states. says there is
