Intramuscular testosterone cypionate (IM-TC) is known to cause significant rises in estradiol (E2), hematocrit (HCT), and prostate-specific antigen (PSA) due to its supraphysiologic testosterone peaks, whereas a novel subcutaneous testosterone enanthate-autoinjector (SCTE-AI) was designed with a lower testosterone peak-to-trough ratio to mitigate these reactions. We compare the total testosterone (TT), E2, HCT, and PSA response to treatment with IM-TC versus SCTE-AI.

肌内注射环戊丙酸睾酮与皮下庚酸睾酮治疗性腺功能减退男性的结果比较。

众所周知，肌肉注射环戊丙酸睾酮 (IM-TC) 会导致雌二醇 (E2)、红细胞比容 (HCT) 和前列腺特异性抗原 (PSA) 显着升高，因为它具有超生理性睾酮峰值，而一种新型皮下庚酸睾酮自动注射器 (SCTE) -AI) 的设计具有较低的睾酮峰谷比以减轻这些反应。我们比较了 IM-TC 与 SCTE-AI 治疗对总睾酮 (TT)、E2、HCT 和 PSA 的反应。
