A health ministry panel plans to limit public aid for in vitro fertilization to women up to 42 years old, given that its success rate diminishes for those approaching 40.

It also said Monday it will provide aid for only up to six treatments, compared with the current 10, as more than 90 percent of successful fertilizations come within six attempts.

For those aged 40 to 42, the upper limit is set at three treatments, as the success rate is lower for this age group. While the decision was based on clinical data, it may come under fire as demand for IVF increases amid a growing tendency to put off marriage.
