Physische Aktivität und Sport bei Kinderwunsch und Kinderwunschtherapie

This selective and narrative literature review discusses the association of physical activity with the incidence of infertility and the outcomes of infertility treatment. Furthermore, studies on mobilization after embryo transfer are summarized and discussed. In obese anovulatory women, moderate physical activity together with weight reduction has been shown to foster normal ovarian function. A more recently published population-based cohort study, however, has indicated that vigorous and frequent training can increase the chance of subfertility and childlessness. In the context of IVF treatment, high level cardiovascular training has been associated with a decrease in pregnancy likelihood and increase in miscarriage rate, respectively. However, some studies indicated that moderate training before and during IVF treatment is rather beneficial. Bed rest after embryo transfer has no association with pregnancy likelihood in women undergoing IVF as evidenced by a number of observational, but also randomized controlled studies.
