Testosterone propionate and Swarna Bhasma treatment modulated D-galactose induced reproductive alterations in male Wistar rats: An experimental study.

Background: The male reproductive system undergoes several adverse age-related changes like decreased hormone synthesis, sperm count, and testicular alteration that can impact on fertility.

Objective: The study aims to investigate the effects of testosterone propionate (TP), and ayurvedic formulation Swarna Bhasma (SB) on D-galactose (D-gal) induced reproductive aging in male Wistar rats.

Materials and methods: 60 male Wistar rats were divided into 10 groups of 6 animals. Reproductive aging was induced by D-gal (150 mg/kg Bwt) exposure for 60 days. The rats were then treated by post and combination treatment with TP (2 mg/kg Bwt) and SB (6.75 mg/kg Bwt). Then sperm parameters, reproductive hormones, inflammatory markers, testicular antioxidant enzymes, steroidogenic enzymes, and histological manifestation of testis were evaluated.

Results: Exposure of D-gal caused significant (p $<$ 0.001) decrease in serum testosterone (T), testicular steroidogenic, and antioxidant enzymes. Administration of TP increased the serum T level, testicular antioxidant enzymes, and spermatogenic profile at a significant level of (p $<$ 0.001) compared to D-gal. Further, the SB treatment significantly (p $<$ 0.001) elevated the serum T level, sperm count, testicular antioxidant enzymes, steroidogenic enzymes, when compared to D-gal.

Conclusion: Both the treatment of TP and SB treatments recovered the reproductive impairments caused by D-gal. However, exogenous T supplementation via TP administration is associated with various side effects during long-term use. SB is an Ayurvedic formulation having a long history of usage in India. The current findings suggest that the SB may be used as a good alternative for potentiating reproductive function in aging males.
