Pregnancy rate in endometriosis patients according to the severity of the disease after using a combined approach of laparoscopy, GnRH agonist treatment and in vitro fertilization.

AIM: To evaluate the effects of combined treatment approaches on endometriosis-associated infertility in different stages of endometriosis using laparoscopy, gonadotropin-releasing hormone (GnRH) agonist (GnRHa) therapy and in vitro fertilization (IVF). METHODS: This retrospective study was carried out on 179 women with surgically confirmed endometriosis. Patients were divided into subgroups: group 1 (stage I-II, n = 121) and group 2 (stage III-IV, n = 58). Patients eligible for IVF, who were found to have adenomyosis or moderate to severe endometriosis, were also given postoperative GnRHa. Pregnancy and delivery rates were cumulatively calculated during 5 years according to the severity of the disease. RESULTS: The overall pregnancy, delivery and miscarriage rates were 66.5, 56.4 and 15.1%, respectively, for all patients following spontaneous and assisted conception. There were no significant differences in reproductive outcomes between the study groups. The pregnancy and delivery rates were also comparable within group 1 between the patients with and without GnRHa treatment. CONCLUSION: Pregnancy and delivery rates at different stages of endometriosis were not affected by the different approaches used for infertility treatment, with >60 and >50% of patients having conceived and delivered a baby, respectively, in both groups. The usefulness of GnRHa treatment for endometriosis patients with minimal to mild forms is questionable and deserves further studies.

IgG, IgA and IgM antibodies against FSH: serological markers of pathogenic autoimmunity or of normal immunoregulation?

PROBLEM: Autoimmune mechanisms are often involved in causing infertility. Among the possible targets of autoantibodies, the follicle-stimulating hormone (FSH) which regulates the follicular maturation in human ovary is a promising candidate. We aimed to study whether anti-FSH-antibodies might be involved in different clinical types of infertility. METHOD OF STUDY: The study group consisted of 178 patients (75 with polycystic ovary syndrome (PCOS), 103 with endometriosis) and 75 pregnant women. Female blood donors formed the control group (n = 85). Indirect enzyme-linked immunosorbent assay tests were performed using purified FSH as antigens and a synthetic peptide corresponding to the 78-93 region (V14D) of the human FSH beta-chain. CONCLUSION: We showed that anti-FSH-antibodies were present in controls and their production decreased during pregnancy. Endometriosis and PCOS were associated with higher values of anti-FSH-immunoglobulin (Ig)A, anti-V14D-IgA, and endometriosis with anti-V14D-IgG. Our data suggest that anti-FSH-IgA could be a marker of ovarian disorders that cause infertility.
