Infertility is the inability to get pregnant after a year of unprotected intercourse.
About 10% of couples in the United States are affected by infertility. Both men and women can be infertile. According to the Centers for Disease Control, 1/3 of the time the diagnosis is due to female infertility, 1/3 of the time it is linked to male infertility, and the remaining cases of infertility are due to a combination of factors from both partners. For approximately 20% of couples, the cause cannot...
"You've got to calm down and let nature take its course."
If you've been trying six months or more to get pregnant, you've probably
lost count of the number of times well-meaning friends and family offered this
or similar advice.
Though the idea that "trying too hard" was once a popular notion,
dramatic advances in infertility treatments -- particularly in the past decade
-- all but did away with that idea.
Now, however, the wheel has turned yet again, and doctors are once more
looking to the idea that stress -- and sometimes "trying too hard" --
may actually play a role in up to 30% of all infertility problems.
"It's becoming more and more important, in terms of what studies we do,
to focus our efforts on the physiological effects of stress and how they may
play a role in conception," says Margareta D. Pisarska, MD, co-director of
Center for Reproductive Medicine at Cedars Sinai Medical Center in Los Angeles
and editor-in-chief of the American Society for Reproductive Medicine
While doctors say that right now there aren't enough data to draw a clear
and obvious link, many believe it's only a matter of time before we connect all
the dots and see the bigger picture.
"What we do know now is that when stress-reduction techniques are
employed, something happens in some women that allows them to get pregnant when
they couldn't get pregnant before," says Allen Morgan, MD, director of
Shore Institute for Reproductive Medicine in Lakewood, N.J.
While the exact pathways between fertility and stress remain a mystery,
Morgan believes hormones like cortisol or epinephrine -- which rise and often
remain high during times of chronic stress -- play a key role.
Morgan says that it's also possible that reducing stress may help enhance
proteins within the uterine lining that are involved in implantation. She says
that stress reduction may increase blood flow to the uterus, which also affects

Pisarska tells WebMD that the effects of stress may be different for each
"Stress may cause one set of reactions in one woman, and something else
in another, so ultimately the reasons behind how or why stress impacts
fertility may also be very individual," says Pisarska.
While doctors may not know the exact links between stress and fertility, a
series of studies shows the impact is hard to ignore.
In research published in the journal Human Reproduction, doctors
compared pregnancy rates in couples that reported being stressed and those who
What they found: Pregnancy was much more likely to occur during months when
couples reported feeling "good" -- happy and relaxed. It was less
likely to occur during the months they reported feeling tense or anxious.
