An open-label, multicenter, randomized, crossover study comparing sildenafil citrate and tadalafil for treating erectile dysfunction in Chinese men naïve to phosphodiesterase 5 inhibitor therapy.

The study was to compare treatment preference, efficacy, and tolerability of sildenafil citrate (sildenafil) and tadalafil for treating erectile dysfunction (ED) in Chinese men naοve to phosphodiesterase 5 (PDE5) inhibitor therapies. This multicenter, randomized, open-label, crossover study evaluated whether Chinese men with ED preferred 20-mg tadalafil or 100-mg sildenafil. After a 4 weeks baseline assessment, 383 eligible patients were randomized to sequential 20-mg tadalafil per 100-mg sildenafil or vice versa for 8 weeks respectively and then chose which treatment they preferred to take during the 8 weeks extension.

[Clinical efficacy of Yougui capsules and Wuziyanzong pills on oligoasthenospermia].

Objective: To investigate the clinical effects of the Chinese traditional medicine Yougui Capsules and Wuziyanzong Pills on sperm viability and motility in patients with oligoasthenospermia.

Methods: A total of 80 infertile men oligoasthenospermia were equally randomized into a trial and a control group, the former treated with Yougui Capsules at 1.68 g tid, while the latter with Wuziyanzong Pills at 6 g bid, both for a course of 12 weeks.

Tissue engineering penoplasty with biodegradable scaffold Maxpol-T cografted autologous fibroblasts for small penis syndrome.

In this study, we investigated the safety and efficacy of a poly acid-co-glycolide biodegradable scaffold (Maxpol-T) coated by autologous fibroblasts (AF) for penile girth enlargement in small penis syndrome (SPS). Eighty patients with SPS were enrolled in a clinical study at 2 medical centers; 69 patients completed the study protocol. Scrotal skin was harvested under local anesthesia, and AFs were cultured and seeded on a Maxpol-T scaffold; the cografted scaffold was implanted under the Buck's fascia of penile shaft via a circumcising incision.

[Safety and tolerance of tadalafil in the treatment of erectile dysfunction].

The benefit of tadalafil should be justified by its safety and tolerance in the chronic treatment of erectile dysfunction (ED) in general and high-risk population. The main treatment-emergent adverse events, chiefly induced by the interactions of tadalafil with PDE5 and isoforms, are mild or moderate in severity, transient and reversible, which may disappear without drug withdrawal. Tadalafil does not add to the risk and severity of cardiovascular problems, and can be safely co-administered with antihypertensives and selective a-receptor blockers.
