The impact of obesity on the outcome of assisted reproduction treatments is debatable. Several studies show that obese women have worse outcomes after undergoing fertility treatment. The researches show a worse response to ovulation induction. In the ovarian stimulation stage these women produce fewer follicles. Fertilization rates are poorer and the embryo quality is lower in young women suffering from obesity. According to some studies, pregnancy rates are lower in obese women and there is an increased risk of early pregnancy loss. Weight loss increases the chance of spontaneous ovulation and conception in women that suffer from overweight and obesity.The aim of this study is to describe the different influencing factors related to body mass index in pregnancy rate achieved by artificial insemination in our population.The results of this study show significant results in patients with higher body mass index was positively associated with duration of infertility, lower levels of luteinizing hormone and intrauterine artificial insemination indication increased .It appears more frequently, but without significant result, anovulation and unexplained cause of infertility among obese women, longer cycles, fewer antral follicles and get fewer mature follicles. The average of pregnancy rates was 12.6% but it did not differ significantly among the body mass index categories.
