London - Working long hours may be good for a woman's career but it could make it difficult for her to conceive, Thai researchers said yesterday.
Dr Pitchaya Tuntiseranee and colleagues at Prince of Songkla University in Thailand found that women who worked more than 71 hours a week took longer to get pregnant. "Our findings imply that long working hours could have an adverse effect on fecundity of the couple which goes beyond the effect on libido and sexual activity," the researchers said in a report in the journal Occupational and Environmental Medicine.
