Doctors See Rise in Second-Birth Infertility
HA NOI — The number of women diagnosed with secondary infertility has risen by 15-20 per cent, according to the director of the National Hospital for Obstetrics and Gynecology,Nguyen Viet Tien.
Secondary infertility is the inability to conceive after already giving birth and, according to Tien, 50 per cent of couples seeking infertility treatments already have one or more children.
HCM City Reproductive Endocrinology and Infertility Association general secretary Ho Manh Tuong said about 60 per cent of female patients diagnosed with secondary infertility had had an abortion or used intra uterine contraceptive devices improperly.
"These activities often result in infections in the uterus, which can cause severe damage," he said.
Tuong said age was another important factor. By 30, the number of eggs produced declines and after 35, the number and quality of eggs decrease precipitously.
"This drop increases the difficulty of conception and the risk of delivering an unhealthy baby," he said.
Tuong explained why secondary infertility was more popular in urban rather than rural areas. "There is a growing trend that women in cities are getting married later as they have to build their career, which means that the second child is probably expected as the woman is on the verge of her mid-thirties. In contrast, most of women in rural areas are still subject to the tradition of early marriage and short birth spacing."
