 Objectives: The aim of this study was to evaluate the relationship between in vitro fertilization (IVF) cycle outcomes, serum and follicular fluid (FF) levels of leptin and ghrelin.

Material and methods: Forty-four women who underwent intracytoplasmic sperm injection cycles (ICSI) were enrolled in the study. On the third day (D3) of the menstrual cycle, venous blood samples were drawn for serum measurements of leptin and ghrelin. The follicular fluid (FF) and the corresponding oocyte were obtained from a single dominant preovulatory follicle at the time of oocyte pick-up. The FF and D3 serum leptin and ghrelin concentrations were measured by enzyme-linked immunosorbent assay. The relationship between pregnancy rate and serum, follicular fluid levels of leptin and ghrelin were analyzed.

Results: Of the 44 cases included, nineteen achieved clinical pregnancy (43.18%). Follicular fluid ghrelin levels were significantly lower in the pregnant group than non-pregnant group (p < 0.05) With respect to FF leptin, there was no statistically significant differences between the pregnant and non-pregnant women (p > 0.05). There was no statistically significant difference in D3 serum ghrelin between pregnant and non-pregnant groups (p > 0.05). However, D3 serum leptin levels were significantly lower in pregnant women than non-pregnant women (p < 0.05).

Conclusions: Lower ghrelin levels in the follicular fluid were associated with higher pregnancy rates. Also, D3 serum leptin levels were inversely correlated with clinical pregnancy rates. These findings support the potential role of these molecules on IVF outcomes.
