Women with sleep disorders other than sleep apnea may be more than three times as likely to experience infertility as their counterparts who don’t have trouble sleeping, reports Deccan Chronicle.

When insomnia was to blame for women’s sleeping difficulties, they were more than four times as likely as peers who slept well to experience infertility, the study also found.

Previous research has linked what’s known as apnea, or disrupted breathing during sleep, with infertility. But the current study looked only at women with other types of sleep disorders, offering fresh evidence of the need for women to pay close attention to healthy habits that can help with sleep if they’re trying to conceive, said lead study author Dr. I-Duo Wang of the Tri-Service General Hospital and National Defense Medical Center in Taipei, Taiwan.
