The effects of P. atlantica as a libido booster and sexual enhancer on the reproductive system of male rats

BACKGROUND AND AIM: Alongside the advancement of various modern treatments, attention has recently been focused on finding alternative infertility treatments based on diet and herbal medicine. Pistacia atlantica (wild pistachio; Baneh) is a plant species traditionally known as a libido booster and sexual enhancer. EXPERIMENTAL PROCEDURE: The study aim was to evaluate the effects of a P. atlantica-enriched diet on the functions of the reproductive system of male rats. RESULTS AND CONCLUSION: Results revealed that the diet containing 20% P. atlantica doubled testosterone levels in the treatment group compared to the control. It decreased the total bodyweight, while significantly increased the ratios of the seminal vesicles, testis, and epididymis to the bodyweight of rats. The sperm count in the treatment group was 4.8 × 10(6)/mL, which was significantly more than the control group (4.2 × 10(6)/mL). Furthermore, the utilization of P. atlantica significantly raised HDL levels, though it reduced the LDL and TG levels and the concentration of testis MDA. Concerning other factors, the 20% of P. atlantica considerably increased the serum level of Zinc and vitamin D. Histomorphometric analysis revealed that the diet increased the testicular capsule thickness, whereas it did not cause any significant change in the diameter of the seminiferous tubule, the number of Leydig cells, and Sertoli cells. Additionally, the repopulation index, tubular differentiation index, and spermiogenesis index increased in the treatment group. Molecular analysis showed that the prescribed diet increased the expression of both oxytocin (OXT) and its receptor (OXTR) genes, improving the reproductive system function.
