If only it were that easy! The fact is, the vast majority of individuals who have infertility have a medical reason, not a stress-related one. Upwards of 90% of all infertility cases are caused by physical problems. In the female partner, the major causes of infertility are absent or irregular ovulation, blocked fallopian tubes, abnormalities in the uterus, and endometriosis (a chronic painful condition where tissue from the lining of the uterus migrates into the pelvis and attaches to the reproductive organs). The male partner can have issues with sperm production which can lead to too few sperm, sperm which can’t swim correctly, and abnormally shaped sperm.
Where the stress/infertility connection may come in tends to be after one has been trying for a while, and the stress of not conceiving easily may then contribute to the problem. But there has never been a study which shows that simply relaxing increases pregnancy rates. Research does show that infertility patients who learn and practice a wide variety of stress reduction techniques can have higher pregnancy rates than patients who don’t learn those techniques.
My side: I have relaxed, I have stressed. I have tried, I have tried harder, I have given up. None of that made any difference in my husband's sperm. And guess what? Timing sex is the only way to ensure you even have a chance, so unless you are committed to sex at LEAST every other day, you need to chart/use OPK's/use a fertility monitor. If you miss your fertile window, you go from a snowball's chance in hell to no chance at all. So maybe relaxing is NOT the answer. If you tend to say this, please stop. If you have a friend or family member that says this you, please share this with them.
