Physical Effects of Stress on Fertility
When the body feels stress, it immediately goes into protection mode. Life preservation ranks higher than reproduction, so getting pregnant when stress levels are high can be difficult. This has nothing to do with a physical inability to conceive, but with genetic wiring. Stress was once defined as physical threat. Today, we react to emotional and perceived stressors in the same way we react to physical stressors. The body does not know the difference and thus reacts the same in both situations. With stress levels high, menstrual cycles can be thrown off cycle or cease all together. This can make ovulation prediction and conception extremely difficult.

The idea that stress causes infertility is an old one. Couples struggling to conceive hear it all the time: "Just relax!" "Have a glass of wine!" "Take the pressure off by adopting a child, and you'll get pregnant in no time!"
Today's researchers, however, believe that psychological factors--while important--are secondary to biological ones. They know that the interaction between factors is complex. And while some studies support the idea that stress-reducing interventions boost pregnancy, the jury is still out.
