If you want to get pregnant, don't stress too much in today's lifestyle. A new study says stressed-out women are less likely to conceive by around 30 percent.
Director of reproductive epidemiology Courtney Denning-Johnson Lynch at The Ohio State University Wexner Medical Center said those women having high levels of alpha-amylase are at an increased risk of infertility.
Alpha-amylase is a protein enzyme and is a biological indicator of stress which is measured in saliva.
Lynch and colleagues studied more than 500 women in the US between the age group of 18 and 40 years who were not having such known fertility problems and had started trying to conceive. The team tracked these subjects for twelve months or until they became pregnant. Saliva samples were collected from all of them.
In the study the researchers found 373 women had presence of alpha-amylase and cortisol in their saliva.
Lynch said the psychological stress leads to lower probability of becoming pregnant in women and the risk is more than two-fold.
Lynch was also the principal investigator of the study and added the new research should encourage women manage their stress using stress reduction techniques if experiencing difficulty in getting pregnant.
The finding is published in the Human Reproduction journal.
There are different reasons too of not getting pregnant apart from the stress like decline in number of healthy eggs and also the health status of partner.
