Monitoring testosterone replacement therapy with transdermal gel: when and how?
Purpose: Testosterone replacement therapy (TRT) is recommended for the treatment of most cases of male hypogonadism. Transdermal testosterone (T) gels are commonly used in clinical practice; however, there is little evidence concerning how to monitor dosage to bring and maintain serum T levels in the normal physiologic range. Methods: We examined 30 hypogonadal patients undergoing treatment with 40 mg/day transdermal 2% testosterone gel.
