Interesting article on Yoga and fertility. I am not sure that any activity that helps reduce your stress is better than any other. If yoga works for you then I highly recommend it.
A couple of quotes Below:
“We will never promise that you will get pregnant by doing yoga,” Ms. Quinn said. “We can tell you many women who have done yoga have gotten pregnant. But there’s no clinical data supporting the fact that yoga increases conception rates. The last thing we would want to do is give false hope.”
Some infertility clinics advise patients not to do vigorous exercise like running for fear of twisting their drug-stimulated enlarged ovaries. (This excruciating condition, called torsion, is rare, but surgery is often required if it happens with the possibility of losing the ovary, said Dr. Brian Kaplan, a partner at the Fertility Centers of Illinois, who advises his patients to limit exercise while taking stimulating drugs.)
But Dr. Domar, the executive director of a namesake center for mind-body health in Waltham, Mass., has found that some women are loath to give up their daily anxiety-relieving run during infertility treatments, or are “freaked out about gaining weight on fertility drugs.” In some cases, yoga is her bargaining chip. She tells those patients, “you can do hatha yoga and stay fit and toned, and give up your run.”
Ms. Spencer explained in an e-mail that for many patients, “There is a feeling of walking on eggshells and also that one false move may throw off the chances of success.” A class like hers lets them move and blow off steam, students said. “It’s like a can of worms,” she said in an interview. “You can’t stop women from talking to one another.”
