Abstract:
Background: Melatonin is a hormone mainly synthesized and secreted from the pineal gland. The daily rhythm of circulatory melatonin is released in very low concentrations during the day and high levels at night. Melatonin has many functions beside regulation of circadian rhythm including immune system and autonomic cardiovascular regulation but the main melatonin function is antioxidant action and detoxification of free radicals.
Patients and method: This cross sectional study was conducted during the period starting from November 2018 to May 2019. Eighty infertile female aged range 18–46 years were enrolled in the present study, the patients were undergoing controlled ovarian induction for IVF /ICSI treatment. All patents were divided into 3 groups according to age, FSH, E2, AMH and ovarian respond to controlled ovarian stimulation (COS) protocols. The follicular fluid melatonin measured at oocyte retrieval day using enzyme linked immunosorbent assay (ELISA).
Results: There was significant difference in follicular fluid melatonin level between the three studied groups (p=0.031). There was also a positive significant correlation between follicular fluid melatonin with MII oocytes (r=0.343; p= 0.024), grade I embryo (r=0.375; p= 0.003) and AMH (r = 0.279; p= 0.027), on the other hand there was a negative significant correlation between follicular fluid melatonin and serum FSH (r = - 0.331; p= 0.016). There was also no significant difference of follicular fluid melatonin levels between pregnant and non-pregnant females (p=0.083).
Conclusion: Melatonin levels in follicular fluid improve the oocytes and embryo qualities but have no effect in positive pregnancy rate.
