  • This summary is based on the review of two randomized controlled trial(s). [1-2]
  • Triptorelin 22.5 mg/24 week depot injections reduced testosterone levels by 29% (95% CI (confidence interval) 17.2-41.7) compared to subcapsular orchiectomy, with a higher proportion of men reaching testosterone levels below 20 ng/dL at both 12 weeks (97% vs 79%) and 48 weeks (100% vs 87%) (p <0.05).
  • No other drugs were included for direct comparison in effectiveness against triptorelin, and no specific population subgroups were highlighted in relation to effectiveness outcomes.
  • No significant differences were observed in fasting plasma glucose changes between triptorelin and orchiectomy groups (0.2 mmol/L, 95% CI -0.1, 0.4; P = 0.32). However, the orchiectomy group exhibited greater increases in total fat mass (+2.06 kg, 95% CI 0.55, 3.56), SAT (+133 cm³, 95% CI 22, 243), and weight (+3.30 kg, 95% CI 0.74, 5.87) at 48 weeks, with increases in fat mass linked to higher insulin resistance (P < 0.001).
  • ADT, including both triptorelin and orchiectomy, resulted in increased fat mass, SAT, VAT, serum cholesterols (total, HDL, LDL), and insulin resistance measures, alongside a reduction in LBM over time (all P < 0.05).
  • There is no population types or subgroups information available in the reviewed studies.
