(Reuters) - Women in Asia are largely ignorant about fertility problems and tend to blame their failure to conceive on "God's will" and bad luck, a survey has found.
The survey, which covered 1,000 women in 10 countries who had been trying to conceive for at least six months, found that 62 percent of them did not suspect they may have a fertility problem.
They were even less likely to point the finger at their husbands, with 80 percent of them not suspecting that their partners may have a problem with fertility.
Infertility is defined by the World Health Organisation as the inability to conceive after a year of regular, unprotected sex. But only 43 percent of the women surveyed knew that.
Only 30 percent of the women, all aged 25-40, recognized that obesity could reduce fertility and only 36 percent knew that chances of getting pregnant declined with age.

Forty-three percent did not know a man may be infertile even if he could achieve an erection and 73 percent were unaware that men who had mumps after puberty could be infertile later on.
Instead of getting treatment, 46 percent of respondents blamed their inability to conceive on "God's will" and 45 percent put it down to bad luck.
Lead researcher P C Wong at the National University Hospital Women's Centre in Singapore said such a lack of understanding could result in couples waiting too long - only to realize when they finally decided to seek help that it may be too late.
"That's a lost opportunity because even if they come for treatment, our success of treatment is higher with younger women," said Wong, who heads the reproductive endocrinology and infertility division at the hospital.
Chances of success with in-vitro fertilization - the best known fertility treatment - is 40-50 percent when a woman is under 30 years old but that drops to 10 percent once the woman is over 40. By 44-45, the chance of success is one percent.
"The reason is because eggs in the ovaries decline in quality and quantity ... as we go along and age, the chances of conceiving is much lower," Wong said by telephone.
The survey, commissioned by Merck KGaA unit Merck Serono, covered China, India, Japan, South Korea, Thailand, Vietnam, Singapore, Hong Kong, Taiwan and Malaysia.
Wong said his team hoped to work on a similar survey targeting men in Asia.
