Country's infertility rate 'on the rise'

Factors behind increase include women's ages, previous abortions

NANNING: The country appears to be suffering from rising infertility levels, with a number of regional surveys showing up to 10 percent of couples who have regular sex being unable to conceive within a year, reproduction experts have said.

No nationwide epidemiology surveys on infertility have been conducted yet, but experts have estimated that the infertility rate stood at 3 percent in the early 1980s.
