Female patients should be observed for signs of virilization. Women should be instructed to report any hoarseness, acne, changes in menstrual periods, or increases in facial hair.

Dosages used to treat delayed puberty are generally started at the lower end of the dosing range and titrated according to patient response and tolerance. The duration of therapy should be limited to 4 to 6 months. Serum concentrations of testosterone should be determined following 3 to 4 weeks of daily use. If desired results have not been achieved at 6 to 8 weeks an alternative testosterone regimen should be considered.
Wrist and hand bone age should be assessed prior to initiation of testosterone therapy and every 6 months to monitor bone maturation. Exogenous androgen therapy can accelerate bone maturation without producing a compensatory gain in linear growth. Use over long periods can result in fusion of the epiphyseal growth centers and termination of the growth process.
