Randomized Controlled TrialTransdermal testosterone gel increases serum testosterone levels in hypogonadal men in Taiwan with improvements in sexual function.
A randomized, double-blind, placebo-controlled trial was conducted to (1) evaluate efficacy and safety of transdermal testosterone gel (AndroGel) for hypogonadal men in Taiwan, and (2) observe improvements in sexual function through international index of erectile function (IIEF) scores. Eligible hypogonadal men were randomized to receive 50 mg/day transdermal testosterone gel (TTG) or placebo for 3 months. Primary end point was change from baseline in total testosterone (TT) and free testosterone (FT). ⋯ TTG group IIEF scores were significantly increased at month 3 (P=0.01), compared with a decline in placebo scores. No drug-related AEs occurred in the TTG group; the placebo group had 2 AEs (mild skin rash). In conclusion, TTG effectively restores serum TT and FT levels to a normal physiological range for hypogonadal men in Taiwan and improves sexual function.

Physician perceptions of sexual dysfunction related to benign prostatic hyperplasia (BPH) symptoms and sexual side effects related to BPH medications.
In a large-scale epidemiology study, 50% of aging men reported erectile dysfunction (ED) or ejaculatory dysfunction (EjD), with lower urinary tract symptoms (LUTS) an independent risk factor for each of these conditions. In light of the shift from urologists (UROs) to primary care/internal medicine physicians (PCPs) for the initial management of men with LUTS associated with benign prostatic hyperplasia (BPH), a survey was conducted to assess the perceptions of UROs and PCPs regarding sexual dysfunction (SD) in men with LUTS/BPH and the effects of BPH treatments (alpha(1)-adrenergic receptor antagonists (alpha-blockers) and 5alpha-reductase inhibitors (5ARIs)) on sexual function. The survey was mailed to 7500 UROs and 2500 PCPs, with 1275 (13%) surveys returned (1087 by UROs, 177 by PCPs and 11 by other specialty). ⋯ UROs were more aware than PCPs of the specific sexual side effects caused by alpha-blockers versus 5ARIs. These results suggest that physicians are underestimating the prevalence of SD in men with LUTS/BPH. As men with LUTS/BPH are at increased risk for SD, physicians should be especially cognizant of BPH treatment-related sexual side effects.

Influence of demographic factors and biochemical characteristics on the prostate-specific antigen (PSA) response to testosterone replacement therapy.
A retrospective study was performed to evaluate how the prostate-specific antigen (PSA) response to testosterone replacement therapy (TRT) varies with age, mode of testosterone treatment, and baseline levels of PSA and testosterone. In total, 48 consecutive hypogonadal men who completed 1 year of TRT were evaluated. All men had a negative prostate biopsy obtained prior to initiating TRT. ⋯ Only 24% of the entire group demonstrated a PSA increase of 0.5 ng/ml or greater. No statistical difference was found in the change in PSA based on patient age, baseline PSA levels, or baseline levels of TT or FT. TRT causes only a mild increase in PSA in most hypogonadal men, and does not appear to be influenced by the mode of TRT, age, or baseline levels of PSA or testosterone.

Pelvic surgeries are among the most common causes of organic sexual dysfunction in men and women. The impact of nerve-sparing surgery on potency has been well documented in radical prostatectomy. However, its impact on potency needs to be evaluated in other pelvic surgeries. ⋯ Currently available treatment options for the female sexual dysfunction include estrogens, androgens, phosphodiesterase inhibitors, and dopamine receptor antagonists. Initial reports regarding the role of early rehabilitation are encouraging and may become the part of routine practice in the management of ED after pelvic surgery. In this article, we summarize the sexual dysfunction following pelvic surgeries and their management.

Randomized Controlled Trial Clinical TrialOral terbutaline in the management of pharmacologically induced prolonged erection.
Prolonged erection and priapism are common complications following intracavernosal injection of vasoactive agents in the management of erectile dysfunction. It is usually treated by intracorporeal drainage and irrigation with sympathomimetic agents. ⋯ Detumescence was achieved in 42 and 15% of the cases with oral terbutaline and placebo, respectively. Results of this study suggest that an initial trial with oral terbutaline for pharmacologically induced prolonged erection may be successful.
