Official title
A Multiple Dose, Pharmacokinetic Study Comparing Different Regimens of Testosterone Given as Intranasal NASOBOL® in Hypogonadal Men in Comparison to Testosterone Levels in Normal Healthy Male Volunteers
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
In this study the serum concentration of testosterone and its main metabolite DHT will be measured in hypogonadal men using intranasal testosterone (Nasobol). Different treatment regimens (once and twice daily) and administration times will be tested. The serum levels obtained will be compared with those of healthy men. It is expected that intranasal administration of Nasobol will restore testosterone and DHT levels to nearly normal.
