"Initial testing typically consists of a hormonal panel (LH, FSH, E2, T, free T, SHBG, and PRL), complete blood cell count, lipid profile, prostate-specific antigen, and a comprehensive metabolic profile...For the severely symptomatic patients, a 4-week tapered course of transdermal or injectable TRT may provide immediate symptom improvement. Simultaneous administration of a SERM (such as clomiphene citrate, 25 mg every other day) will interact at the hypothalamus causing stimulation of LH and ultimately increase intratesticular T. For patients with ASIH-induced gynecomastia, 20 mg tamoxifen daily will block the breast estrogen receptors and stimulate HPG axis recovery.
After 4 weeks of treatment with TRT and/or a SERM, repeated hormone panels should be obtained. If the patient has had either a poor gonadotropin response or a poor T response, the authors commence a 4-week course of hCG (1,000–3,000 IU, 3 times per week) while continuing daily treatment with a SERM at the initial starting dose. If a patient develops gynecomastia while on hCG, tamoxifen (10 mg b.i.d.) or anastrazole may be commenced. After 8 weeks of hCG and adjunctive treatment, hormone levels should once again be assessed. At this point, if the total serum T remains low and the patient continues to be symptomatic, primary testicular failure is likely. These patients will require a longer duration of TRT to avoid permanent ASIH. If appropriately increased serum T and gonadotropin levels are observed, the SERM may be reduced to 50% of its starting dose at 10 weeks of treatment and continued through weeks 12–16 or until target serum T level is achieved."
