There are a number of reasons that IVF and Assisted Reproductive Technology (ART) are becoming more common. These include the overall decline in the global fertility rate (decline in both male fertility, and female fertility as women postpone the age they try to conceive); the rising number of fertility clinics worldwide; technological advancements; and increasing public-private investments, funds, and grants.
The world is experiencing a major fertility crisis, caused by both sociological and environmental circumstances. If the current rate of male infertility decline continues, researchers predict that 50% of men will be infertile by 2045.
