The protective effect of cilostazol on experimental ischemia/reperfusion injury in rats ovaries on in vitro fertilization outcomes.

OBJECTIVE

Ovarian torsion decreases ovarian reserve because of ischemic and reperfusion damage it causes. In this study, we investigated the protective effect of cilostazol (CIL) on experimental ischemia (I) and ischemic-reperfusion (I/R) damage in rat ovaries with in vitro fertilization (IVF) results.

MATERIALS AND

METHODS

Forty-eight adult female Sprague-Dawley albino rats were randomly assigned to 6 groups with 8 animals in each group: Sham (S), I, I/R, S + CIL, I + CIL and I/R + CIL. The I groups were subjected to bilateral adnexal torsion for 3 h, while the I/R and I/R + CIL groups received subsequent detorsion for 3 h. Twenty-two mg/kg of CIL was given via oral gavage 30 min before surgery on the I (I+ CIL) or reperfusion (I/R + CIL) groups. Oocytes were collected before the IVF procedure and after ovulation induction with 150-300 IU/kg pregnant mare serum gonadotropin.

RESULTS

The metaphase oocytes reached their highest value of 4.73±0.96 in the S+ CIL group and reached their lowest value of 0.51±0.55 in the I/R group. There were statistically significant differences in the number of second-day embryos among the I, I+ CIL, and I/R and I/R+ CIL groups (p=0.000). When the groups were compared in terms of Anti-Müllerian hormone change, the highest decrease was observed in the I and I/R groups.

CONCLUSION

CIL pretreatment before surgery has a protective effect against I and I/R in rats with ovarian torsion.
