The level of melatonin in the blood and follicular fluid in women with infertility in the program of assisted reproductive technologies and the effectiveness of its application

Abstract

Objective was to investigate the level of melatonin in the blood and follicular fluid in women treated with infertility by ART method and evaluate the effectiveness of melatonin in their preparation for programs.Material and methods. 89 women were examined. The first (control) group included 13 healthy women oocyte donors who gave birth to their own healthy children, the second group - 33 women with infertility, who two weeks before and during ovulation stimulation were taken simultaneously at the same time before bedtime 3 mg of the drug "Vita-melatonin" produced by "Kyiv Vitamin Plant", the third group - 43 women with infertility who did not take the drug melatonin during ovulation stimulation. ELISA (Germany) reagent kits were used to determine melatonin levels. Melatonin levels were determined in blood plasma, and follicular fluid obtained during the puncture at 9:00 am.Results. The level of melatonin in the blood of female donor oocytes was 130.85 ± 16.91 pg/ml. This rate in the blood of women who used the drug melatonin before and during ovulation stimulation was significantly higher than in the blood of women who did not take the drug (respectively, 143.06 ± 14.87 pg/ml and 123.40 ± 12.65 pg / ml, p <0.05), and in the follicular fluid there was an inverse relationship: the level of melatonin in women of the first group was 97.15 ± 8.69 pg / ml, the second group - 39.46 ± 4.52 pg/ml, which is significantly less (p <0.05), the third group - 62.34 ± 3.94 pg / ml, which is almost twice more (p <0.05) compared with women who took melatonin, but less (p <0.05) compared with the first group. The frequency of pregnancy on transfer in patients of the first group was 80.0 ± 11.01%, in women of the second group probably less - 60.6 ± 8.25% (p <0.05), but also probably higher compared to women in the third group - 45.0 ± 7.62% (p <0.05). A similar pattern was observed by us on the onset of pregnancy in general: in the first group - 100.0%, in the second - 68.9 ± 8.05% (p <0.05), in the third - 60.5 ± 7.47% (p> 0.05).Conclusions. The low level of melatonin in the follicular fluid obtained by us in women who underwent ovulation stimulation in ART programs in the treatment of infertility requires further scientific interpretation. At the same time, the best results of pregnancy in women in ART programs who took melatonin in preparation are encouraging.
