Fertility treatment increasing multiple births

The rate of multiple births for mothers who receive fertility treatments is higher than 20 percent in some areas of China, the top health authority said in an exclusive email exchange with China Daily.

The National Health and Family Planning Commission also warned of the potential health risks facing both the mother and babies from a multiple pregnancy and birth.

Experts say the incidence of twins through natural pregnancy is only 1 percent, and triplets or more are much rarer.
