Purpose: We investigated the clinical and physiological effect of low intensity extracorporeal shock wave therapy on men with organic erectile dysfunction who are phosphodiesterase type 5 inhibitor responders. Materials and Methods: After a 1-month phosphodiesterase type 5 inhibitor washout period, 67 men were randomized in a 2:1 ratio to receive 12 sessions of low intensity extracorporeal shock wave therapy or sham therapy. Erectile function and penile hemodynamics were assessed before the first treatment (visit 1) and 1 month after the final treatment (followup 1) using validated sexual function questionnaires and venoocclusive strain gauge plethysmography. Results: Clinically we found a significantly greater increase in the International Index of Erectile Function-Erectile Function domain score from visit 1 to follow up 1 in the treated group than in the sham treated group (mean SEM 6.7 0.9 vs 3.0 1.4, p 0.0322). There were 19 men in the treated group who were initially unable to achieve erections hard enough for penetration (Erection Hardness Score 2 or less) who were able to achieve erections sufficiently firm for penetration (Erection Hardness Score 3 or greater) after low intensity extracorporeal shock wave therapy, compared to none in the sham group. Physiologically penile hemodynamics significantly improved in the treated group but not in the sham group (maximal post-ischemic penile blood flow 8.2 vs 0.1 ml per minute per dl,p 0.0001). None of the men experienced discomfort or reported any adverse effects from the treatment. Conclusions: This is the first randomized, double-blind, sham controlled study to our knowledge that shows that low intensity extracorporeal shock wave therapy has a positive short-term clinical and physiological effect on the erectile function of men who respond to oral phosphodiesterase type 5 inhibitor therapy. The feasibility and tolerability of this treatment, coupled with its potential rehabilitative characteristics, make it an attractive new therapeutic option for men with erectile dysfunction

Women's Sexuality Post Spinal Cord Injury

Women's Sexuality Post Spinal Cord Injury

Spinal Cord Injury (SCI) is a traumatic event that results in a sudden life change that is difficult to conceptualise. No one can truly be prepared for such a huge shock. It impacts a person not just physically and neurologically, but also socially, emotionally and psychologically. Recovering from SCI has been likened to a “rebirth”. A person needs to reconstruct even the most basic activities of daily living. Sexuality, being an integral part of every person’s life, is also part of this reconstruction process. 

Sexual Orientation Identity Development: Implications for the Psychological Adjustment of Gay and Bisexual Young Males in Japan

Sexual Orientation Identity Development: Implications for the Psychological Adjustment of Gay and Bisexual Young Males in Japan

According to previous studies, lesbian, gay, and bisexual (LGB) people report lower levels of mental health relative to heterosexuals. Young LGB people especially suffer from poorer psychological adjustment. However, it remains unclear whether different developmental identity patterns have implications for the psychological adjustment of LGB youths. There is a possibility that the development of sexual orientation identity is related to the better mental health among young LGB people. This study examines whether different patterns of LGB identity formation and integration are associated with psychological adjustment.
