Testosterone replacement in hypogonadal men improves body composition, mood, and sexual functioning. In this 90-d study, we compared the pharmacokinetics and treatment effectiveness of a topical testosterone gel (AA2500) at two concentrations, 50 mg/d and 100 mg/d, to a testosterone patch and placebo gel in 406 hypogonadal men. Pharmacokinetic profiles were obtained, body composition was measured, and mood and sexual function were monitored. AA2500 treatments resulted in dose-dependent improvements in all pharmacokinetic parameters, compared with testosterone patch and placebo. Mean average concentrations at d 90 T were 13.8, 17.1, 11.9, and 7.3 nmol/liter for 50 mg/d AA2500, 100 mg/d AA2500, testosterone patch, and placebo, respectively. At d 90, the 100 mg/d AA2500 treatment improved lean body mass by 1.7 kg and percentage of body fat by 1.2% to a significantly greater degree than either control treatment. Significant improvements in spontaneous erections, sexual desire, and sexual motivation were also evidenced with the 100 mg/d AA2500 dose in comparison with placebo. Testosterone gel was well tolerated; however, the testosterone patch resulted in a high rate of application site reactions. Overall, AA2500 is an effective, well tolerated treatment for hypogonadism.

In the largest prospective, randomized clinical trial reported to date with intravesical vanilloid therapy, single administration of RTX at doses of 0.01 microM to 0.10 microM was not effective in patients with interstitial cystitis.

This new minimally invasive male sling procedure is safe and efficacious. Adjusting sling tension by measuring urethral resistance results in a low rate of over correction and failure. Further experience is needed to establish this procedure as treatment for post-prostatectomy incontinence.

To our knowledge this study is the first to evaluate rofecoxib versus placebo in patients with prostatitis and the first large multicenter treatment study to use the NIH-CPSI. Subjective assessment with patient global questions may be more sensitive to change than the NIH-CPSI and, therefore, may be a better tool to use in future therapeutic trials. Although 6 weeks of rofecoxib treatment appear to benefit many men diagnosed with chronic prostatitis/chronic pelvic pain syndrome further studies are needed.
