`Abstract
`We undertook a prospective survey of the tolerability of deep i.m. injections of testosterone
`enanthate in a castor oil vehicle, the most widely used form of androgen replacement therapy. Over
`a period of 8 months, 26 men received 551 weekly injections into the gluteal, deltoid or thigh muscle
`and side-effects were recorded immediately and 1 week after each injection by the same nurse using
`a standardized questionnaire. Most injections caused no complaints [389/551, 70.6%> (95%>
`confidence interval66.6-74.4%>)] but minor local side-effects, mostly pain and bleeding, were
`common [162/551, 29.4%> (25.6-33.4%)]; no serious side-effects were observed. Considering all
`side-effects, the gluteal site had fewer complaints and was less prone to bleeding but was painful
`more often than deltoid or thigh injection sites. The laterality of injection at any site had no significant
`effect on side-effects. The only systemic side-effect was episodes of sudden-onset, non-productive
`cough associated with faintness following eight injections [1.5% (0.6-2.9%)] which we speculate may
`have been due to pulmonary oil microembolism. We conclude that, when administered by an
`experienced nurse, deep i.m. injection of testosterone enanthate in a castor oil vehicle is generally
`safe and well tolerated but causes relatively frequent minor side-effects, including pain and bleeding.
`An improved depot form of testosterone would be highly desirable for androgen replacement therapy
`and hormonal male contraception.
