The hormonal mechanism of the effects of meperidine, sertraline, tianeptine, and their combinations on reproductive functions in female rats

Abstract

Background: Infertility caused by drugs that inhibit serotonin reuptake has been attributed to serotonin toxicity. Serotonin has been linked to cause a rise in prolactin and cortisol. This study examined the effects of meperidine, sertraline, tianeptine and combinations on female rat reproductive function. Methods: Female rats were split into 8 groups (n=7): healthy control (HG), meperidine (MG), sertraline (SG), tianeptine (TG), meperidine+sertraline (MSG), meperidine+tianeptine (MTG), sertraline+tianeptine (STG), meperidine+sertraline+tianeptine (MSTG). Meperidine (20 mg/kg, 2×1) was injected intramuscularly. Sertraline (30 mg/kg, 1×1) and tianeptine (5 mg/kg, 1×1) were given orally. The HG received distilled water as solvent. Treatments continued for 20 days. Then, adult males were added to the rat groups and drug treatment continued for another five days. Blood samples were collected on day 26 for biochemical tests. Results: Total oxidant status (TOS) and total antioxidant status (TAS) were not statistically significant between groups (p>0.05). Meperidine (p0.05). Number of infertile animals was 6 for meperidine, 3 for sertraline, and none for tianeptine. While the duration of pregnancy in MG (15 days) and SG (15 days) was longer compared to HG (2.86 days), no change was observed in TG (2.5 days). Conclusion: Tianeptine and other serotonin re-uptake stimulants may be useful in the treatment of reproductive dysfunction and infertility due to serotonin re-uptake inhibitor treatment.
