Along with the prevalence of overweight women, there is an increase in women with anovulatory infertility. Thus, we carried out a bibliographic research in the PubMed, Lilacs and SciELO databases, using the combinations in Portuguese, Spanish and English of the following descriptors: "Body Mass Index", "obesity", "overweight", "female infertility" and "anovulation". The aim of this study was to assess the effects of obesity on the ovulatory profile of infertile women in the available literature.

Controlled ovarian stimulation has become an integral part of a high complexity infertility treatment. Treatment options with recombinant gonadotrophins add more to knowledge on folliculogenesis and ovarian steroidogenesis. Therefore, a literature search was conducted in the following data bases: Medline, Scielo and PubMed. The descriptors/key words used were ovarian stimulation, in vitro fertilization, recombinant luteinizing hormone, supplementation LH. The aim of this study was to review the available literature and to assess the benefits of using recombinant luteinizing hormone associated with recombinant follicle stimulating hormone in different populations who have undergone assisted reproduction procedures.
