Background and Objective: Morphine can induce PCOS (Polycystic ovary syndrome) probably by changing glutamate level at the hypothalamic nuclei. This study used low doses of ketamine to survey the interaction of ketamine with morphine-induced PCOS.
Materials and Methods: 48 female Wistar rats were selected as virgins in the weight range of 220-250 g, and categorized randomly into eight groups. The first group received morphine (5 mg/kg) intraperitoneally. The second to fourth groups received ketamine (1, 2, and 4 mg/kg). In groups 5 to 7, the ketamine (1, 2, and 4 mg/kg) was pre-injected to morphine (5 mg/kg) over a period of 20 min. Control group received only saline (1 ml/kg). After 48 h, the blood and serum specimens were provided to record hormone levels, and the animals’ ovaries and uteri were biometrically examined and stained by H & E. Statistical analysis was performed by analysis of variance (ANOVA) under α=0.05.
Results: The morphine as well as single ketamine induced the PCOS. However, taking ketamine prior to morphine caused a meaningful reduction in the number of cysts in the ovary. There was also a relative increase in uterine diameter in the group receiving morphine, which was stopped due to ketamine pre-treatment. These effects showed correlation with decreased levels of FSH, and change in estrogen, and prolactin amounts.
Conclusion: The interference effect of ketamine with morphine is completely dependent on changes in gonadotropin level.
