Trouble Conceiving? Stress Could Be to Blame Published: March 24, 2014

Stress may affect some women's chances of becoming pregnant, according to LiveScience.

Researchers found that women who had higher levels of an enzyme in their saliva called alpha-amylase, an indicator of stress, took longer to conceive. The study is the first to show a link between infertility in women and stress levels measured in saliva.

"We showed that women who had the highest levels of alpha-amylase were more than twice as likely to not become pregnant after 12 months as women who had the lowest amounts," said study author Courtney Lynch, a reproductive epidemiologist at The Ohio State University College of Medicine.
