A better understanding of fertility should help raise the success rate of IVF, bringing down its emotional and financial costs. That is why it needs investment and regulation
In a world where one person in six suffers from infertility, such successes are rightly celebrated. Less discussed are. Most courses of treatment fail. That subjects women and couples to cycles of dreaming and dejection—and gives the fertility industry an incentive to sell false hope. The obstacle is a lack of progress in understanding
Yet the process remains gruelling and costly. It is physically painful for women, and emotionally draining for both sexes. For many, fertility treatment is an unaffordable luxury; in America, for instance, a cycle can cost $20,000. Some countries ration treatment according to a conservative moral code. Until 2021 French law permittedonly for married heterosexual couples. Many countries including China forbid egg freezing, which extends reproductive years.
“add-ons” that do not demonstrably raise the chances of success, and may even reduce them. They can charge hundreds to thousands of dollars for a treatment. Little is known about how a woman’s stock of eggs is set before she is even born; or why they fade in number and quality until menopause, which among mammals is known to occur only in humans and five species of whale. The intricacies of how an embryo buries into the womb and connects to the blood supply are also mysterious. Infertility is often classed as “women’s health”, yet male factors play at least some role in roughly half of heterosexual infertile couples—though how is often unclear.
