Background: Despite the common practice of intraarticular corticosteroid injections (ICSIs) for peripheral joint disease, little is known about their systemic effects on the hypothalamic-pituitary-gonadal axis., Objective: To assess the short-term effects of ICSIs on serum testosterone (T), luteinizing hormone (LH), and follicle stimulating hormone (FSH) levels together with changes in Shoulder Pain and Disability Index (SPADI) scores in a veteran population., Design: Prospective pilot study., Setting: Outpatient musculoskeletal clinic., Participants: Thirty male veterans, median age 50 (range 30-69) years., Interventions: Ultrasound-guided glenohumeral joint injection using 3 mL of 1% lidocaine HCl and 1 mL of 40 mg triamcinolone acetonide (Kenalog)., Outcome Measure(s): Serum T, FSH, and LH levels, Quantitative Androgen Deficiency in the Aging Male (qADAM), and SPADI questionnaires at baseline, 1, and 4 week(s) post procedure., Results: At 1 week post injection, serum T levels decreased by 56.8 ng/dL (95% confidence interval (CI): 91.8, 21.7, p = .002) compared with baseline. Between 1 and 4 weeks post injection, serum T levels increased by 63.9 ng/dL (95% CI: 26.5, 101.2, p = .001), recovering to near baseline levels. SPADI scores were reduced at 1 week (-18.3, 95% CI: -24.4, -12.1, p < .001) and 4 weeks (-14.5, 95% CI -21.1, -7.9, p < .001)., Conclusions: A single ICSI can temporarily suppress the male gonadal axis. Future studies are needed to evaluate for long-term effects of multiple injections at a single setting and/or higher corticosteroid doses on male reproductive axis function., (© 2023 American Academy of Physical Medicine and Rehabilitation.)
