Testosterone (Testosterone Cypionate) - Summary

TESTOSTERONE SUMMARY

Testosterone gel is a clear, colorless hydroalcoholic gel containing testosterone. The active pharmacologic ingredient in testosterone gel is testosterone, an androgen.

Testosterone is an androgen indicated for replacement therapy in adult males for conditions associated with a deficiency or absence of endogenous testosterone:

• •Primary Hypogonadism (congenital or acquired) - testicular failure due to conditions such as cryptorchidism, bilateral torsion, orchitis, vanishing testis syndrome, orchiectomy, Klinefelter’s syndrome, chemotherapy, or toxic damage from alcohol or heavy metals. These men usually have low serum testosterone concentrations and gonadotropins (follicle stimulating hormone (FSH), luteinizing hormone (LH)) above the normal range.
• •Hypogonadotropic hypogonadism (congenital or acquired) - idiopathic gonadotropin or luteinizing hormone-releasing hormone (LHRH) deficiency or pituitary-hypothalamic injury from tumors, trauma, or radiation. These men have low testosterone serum concentrations but have gonadotropins in the normal or low range.

Important limitations of use:

• •Safety and efficacy of testosterone gel in males less than 18 years old have not been established [ see Use in Specific Populations (8.4) ].
• •Topical testosterone products may have different doses, strengths, or application instructions that may result in different systemic exposure. (1, 12.3)

Testosterone replacement therapy in older male subjective memory complainers: double-blind randomized crossover placebo-controlled clinical trial of physiological assessment and safety. [2015]
Testosterone replacement therapy (TRT) has been investigated in older men as a preventative treatment against Alzheimer's disease and dementia. However, previous studies have been contradictory... Our study suggests TRT is safe and well-tolerated in this Indonesian cohort, yet longitudinal studies with larger cohorts are needed to assess TRT further, and to establish whether TRT reduces dementia risk.

Testosterone induces erythrocytosis via increased erythropoietin and suppressed hepcidin: evidence for a new erythropoietin/hemoglobin set point. [2014]
hematocrit remain unclear... CONCLUSIONS: Testosterone-induced increase in hemoglobin and hematocrit is
