BACKGROUND: Melatonin, a hormone found in various bodily fluids and cells, is known for its potent antioxidative, anti-apoptotic, and endocrine regulatory properties. This study aimed to analyze melatonin levels in patients with diminished ovarian reserve (DOR) and its impact on embryo quality.
METHODS: We enrolled 85 women who were undergoing in vitro fertilization or intracytoplasmic sperm injection procedures, including normal ovarian reserve (NOR, n = 27), pathological DOR (DOR-Path, n = 25), and physiological DOR (DOR-Phy, n = 33). Melatonin levels in patient serum and follicular fluid were assessed using ELISA, and correlations between melatonin levels and indicators of embryo quality were examined.
RESULTS: Our findings indicate that melatonin levels in the follicular fluid and basal serum of the DOR-Path and DOR-Phy groups were lower compared to the NOR group (P < 0.05). However, no significant differences in melatonin levels were found between the DOR-Path and DOR-Phy groups (P > 0.05). Additionally, the concentration of melatonin in the follicular fluid of the NOR group was significantly higher than in their serum (P < 0.001). Lastly, a significant correlation was discovered between melatonin levels in serum and follicular fluid and parameters of ovarian reserve and embryonic development (P < 0.05).
CONCLUSIONS: Melatonin levels in DOR patients may impact embryo quality, offering insights into potential DOR pathogenesis and opportunities to enhance treatment outcomes in these patients.
