Psychotherapy aimed at dealing with stress, greatly increase the chances of conceiving a child in women with infertility. These conclusions were American scientists who have submitted a report on the study on European Society of Human Reproduction and Embryology. The study, which had a staff of Emory University in Atlanta, attended by 18 women aged 25 to 35 years with a diagnosis of secondary amenorrhea – chronic disruption of the menstrual cycle. All participants experienced a lack of gonadotropin-releasing hormone (GnRH), which plays an important role in regulating ovulation, combined with high levels of the hormone cortisol, responsible for stress. Length of menstrual cycle in women is not less than six months. Study participants were divided into two equal groups. Woman in the first group for 20 weeks went to courses of cognitive-behavioral therapy aimed at increasing self-esteem of patients and learning to cope with stress. Women are the second group received no treatment. By the end of the 20 th week of the menstrual cycle bounced back from 80% of women attending psychotherapy. In the control group, the restoration of the menstrual cycle was observed in only 25% of participants. "It's hard to believe that infertility can cause a simple stress, but the proof is the fact that lowering the level of the hormone cortisol leads to increased production of gonadotropin-releasing hormone "- said project coordinator Professor Sarah Berga.
