High Stress Reduces Woman’s Chance of Pregnancy

Researchers have finally confirmed that a women’s high stress reduces their probability of conception.

Investigators from the University of Louisville and Emory University found that women who reported feeling more stressed during their ovulatory window were approximately 40 percent less likely to conceive during that month than other less stressful months.

Similarly, women who generally reported feeling more stressed than other women, were about 45 percent less likely to conceive, says study leader, Kira Taylor.

The research results appear in the journalĀ Annals of Epidemiology.

In the study, 400 women 40-years-old and younger who were sexually active recorded their daily stress levels measured on a scale from one to four (low to high).

The diaries also contained information regarding menstruation, intercourse, contraception, alcohol, caffeine, and smoking.

Urine samples also were collected throughout the study, and women were followed until they became pregnant or until the study ended, for an average of eight menstrual cycles.

Researchers calculated mean stress levels during each phase of the menstrual cycle, with day 14 as the estimated time of ovulation.

They found the negative effect of stress on fertility was only observed during the ovulatory window, and was true after adjustments for other factors like age, body mass index, alcohol use, and frequency of intercourse.

“These findings add more evidence to a very limited body of research investigating whether perceived stress can affect fertility,” Taylor said.

“The results imply that women who wish to conceive may increase their chances by taking active steps towards stress reduction such as exercising, enrolling in a stress management program, or talking to a health professional.”

The study also found that women who did conceive experienced an increase in stress at the end of the month in which they became pregnant.

Taylor believes this observation could be the result of two factors.

One scenario is that women became stressed after taking a home pregnancy test and learning they were pregnant. However, the most likely reason for the increased stress is hormonal changes caused by pregnancy itself.

“Some individuals are skeptical that emotional and psychological attributes may be instrumental in affecting fertility,” Taylor said.

“I hope the results of this study serve a wake-up call for both physicians and the general public that psychological health and well-being is just as important as other more commonly accepted risk factors such as smoking, drinking alcohol, or obesity when trying to conceive.”
