Although Wang Xia has a successful career as a university lecturer in Henan province, life isn't perfect. She cannot bear a child.
"I really want to have a child, and I've tried several hospitals for treatment but failed," Wang said, adding that she ended up divorced from her husband because they could not have a child.
Wang became pregnant after she got married but went for an induced abortion because she wanted to pursue her career.
A surgical infection caused her reproductive difficulties.
According to the China Population Association, more than 40 million Chinese people are diagnosed with infertility, 12.5 percent of those of childbearing age. The rate was only 3 percent 20 years ago.
The first test tube baby on the Chinese mainland was born in 1988 at the Center of Reproductive Medicine of the Third School of Clinical Medicine of Peking University, where every day about 1,500 patients wait to see reproductive experts.
Qiao Jie, director of the center, said many professional women postpone marriage and having a child.
"Their reproductive ability deteriorates when they eventually want a child," Qiao added.
