Randomized Controlled TrialEffect of operative local anesthesia on postoperative pain outcomes of inflatable penile prosthesis: prospective comparison of two medications.
Few studies have examined the roles of dorsal penile nerve block (DPNB) and penile ring block (PRB) in surgery of inflatable penile prosthesis (IPP) placement. We sought to compare the postoperative pain outcomes of two different medications used in DPNB plus PRB. We thus carried out a prospective study of patients with erectile dysfunction who underwent "de novo" IPP placement between January 2013 and June 2013. ⋯ Two hours postoperatively, mean VAS was significantly different (p < 0.0001) between medicated patients and the control group, however, no significant differences were observed between medication groups. Mean VAS was not significantly different among the groups from post-surgical day 2 thru 7. In conclusion, DPNB plus PRB during IPP provided effective analgesia in the immediate post-operative recovery.

Quality analysis of randomized controlled trials in the International Journal of Impotence Research: quality assessment and relevant clinical impact.
The quality of randomized controlled trials (RCTs) reported in the International Journal of Impotence Research (IJIR) was analyzed. The original articles that reported RCTs and were published in the IJIR in 1997-2014 were identified by PubMed. Their methodological quality was assessed using the Jadad scale, van Tulder scale and Cochrane Collaboration Risk of Bias Tool. ⋯ Intervention and funding significantly influenced RCT quality. Thus, the number of RCTs published in the IJIR over time has remained constant while their quality has improved. Ongoing efforts to expand the numbers of RCTs and further improve the quality of research published by the IJIR will improve clinical practice.

Ejaculatory training lengthens the ejaculation latency and facilitates the functioning of the spinal generator for ejaculation of rats with rapid ejaculation.
A spinal pattern generator controls the ejaculatory response. Central pattern generators (CPGs) may be entrained to improve the motor patterns under their control. ⋯ The data obtained show that intense ejaculatory training of rats with rapid ejaculation lengthens the ejaculation latency during copulation and augments the ejaculatory capacity of the SGE in this population when spinalized. Thus, present data reveal that like other CPGs, the SGE can be trained and put forward that training of the SGE by daily copulation to ejaculation might be a promising alternative that should be taken into consideration for the treatment of premature ejaculation.

Chronic antidepressant treatment is associated with sexual side effects, particularly affecting the ejaculatory response. Bupropion (BP), an antidepressant inhibiting dopamine/noradrenaline reuptake, seems to have a low impact upon male sexual function. Ejaculation is regulated both at the brain and spinal cord by the spinal generator for ejaculation (SGE). ⋯ Chronic treatment with the low dose of BP produced deficits in the functioning of the SGE that were restored by activation of the SGE through afferent stimulation. Conversely, chronic treatment with the high-dose of BP disrupted the functioning of the SGE, as the deficits were not compensated by activating the SGE through sensory stimulation. It is concluded that chronic BP at high doses alters the functioning of the SGE.

The relationship between age and brain response to visual erotic stimuli in healthy heterosexual males.
The various changes of sexuality, including decreased sexual desire and erectile dysfunction, are also accompanied with aging. To understand the effect of aging on sexuality, we explored the relationship between age and the visual erotic stimulation-related brain response in sexually active male subjects. ⋯ Our results showed age was positively correlated with the activation of right occipital fusiform gyrus and amygdala, and negatively correlated with the activation of right insula and inferior frontal gyrus. These findings suggest age might be related with functional decline in brain regions being involved in both interoceptive sensation and prefrontal modulation while it is related with the incremental activity of the brain region for early processing of visual emotional stimuli in sexually healthy men.
