Careful insight into the complete state of health of women and men can reveal the causes of sterility. Some problems require treatment that will ensure spontaneous conception. The gynecologist conducts precise analyzes of the complete reproductive system, examination and treatment of specific infections, determination of hormonal imbalances and therapies, checking of the patency of the fallopian tubes as well as the appearance and quality of the interior of the uterus where the embryo should “nest”. In addition, a gynecologist must, like any medical professional, have the power to look at the body as a whole. With an individual approach to each patient, respect for modern approaches to medicine. Along with examining the condition of the woman, it is also necessary to examine the partner. Only with this approach can the success of a possible and spontaneous conception be ensured, as well as the right choice of the type and method of in vitro fertilization.
