Infertility is a growing problem of modern world. Endometriosis, polycystic ovary syndrome and tubal abnormalities are most common gynaecological disorders that lead in female infertility. Because of more and more couples needing in vitro fertilization (IVF), this problem is very interesting for research (diagnosis, monitoring and treatment of infertility).IVF requires many diagnostic tests. One of them is the measurement of the concentration of Anti-Müllerian hormone (AMH) in serum. AMH is produced in ovary and regulates development of primary follicles, therefore it is an excellent marker of ovarian reserve. Decreased concentration of AMH in a biological sample, reflects lower quantity and quality of ovarian follicles. Quality of ovarian follicles can also be assessed by measurement of total antioxidative status (TAS). The purpose of our work was to investigate the association between concentration of AMH in the follicular fluid and serum in three groups of female patients with various diagnoses of infertility. We also studied the association between the TAS and concentration of AMH in follicular fluid. Female patients with first time IVF were included in this study. From these women we collected follicular fluid in the process of ovum biopsy. At the same time we also collected blood for determination AMH and TAS. The patients were divided into three groups: group with tubal abnormalities (control) (40 patients), group with endometriosis (70 patients) and group with polycystic ovarian syndrome (37 patients). We determined concentration of AMH in serum and follicular fluid with ELISA principle and concentration of TAS in follicular fluid with colorimetric method. We found that concentration of AMH in serum (S – AMH) and AMH in follicular fluid (FT – AMH) are not statistically different within each of the groups. The value of S - AMH reflects the value of FT - AMH. On the other hand we found no significant difference between S - AMH between group with tubal abnormalities and group with endometriosis. We also found no significant difference between FT - AMH between group with tubal abnormalities and group with polycystic ovarian syndrome. Furthermore, level of TAS in follicular fluid (FT – TAS) does not affect concentration of FT – AMH. There is a significant difference between concentrations of FT – TAS in all three groups. Based on these results, we can conclude that serum and follicular fluid can be used for measurement of concentration of AMH. It also can be concluded that concentrations of AMH are not different between all three groups of female patients. The presence of FT - TAS also has no effect on concentration of FT - AMH.
