The Protective Effects of Aloe Vera Gel Extract on the Sexual Complications Caused by Diabetes in Male Rats

Introduction: Diabetics usually suffer from chronic complications, including microvascular and macrovascular disorders. The capillaries supplying the sexual organs affect normal sexual functions. The erectile process has been shown to be impaired in diabetics. Vascular damage in diabetics may be associated with decreased testosterone production, sperm count, testicular weight, and seminiferous tubule diameter. In this study, we investigated the effects of Aloe vera gel extract (from Sistan and Baluchistan, Iran) on the male genital system in streptozocin-induced diabetic rats. Methods: A total of 24 male Wistar rats were included in the study. Diabetes was induced in 12 rats by intraperitoneal injection of a single dose of streptozotocin (STZ). The rats were divided into four groups. The first and third groups received saline (NaCl) by gavage daily. The second and fourth groups received Aloe vera gel extract daily by gavage. Treatments were continued for 30 days. At the end of the treatment period, blood samples were taken and serum glucose and testosterone levels were measured by photometric methods. Histological examinations were performed on the prostate and testes. Results: Mean weight index, serum levels of glucose and testosterone, mean sperm count, germinal epithelium (GE) thickness, and seminiferous tubule diameter improved significantly in the diabetes+Aloe vera group. Conclusion: We concluded that consumption of Aloe vera gel extract improved sexual complications in diabetic rats.
