Advances in superenzyme gene therapy in penile rehabilitation / 中华男科学杂志

Erectile dysfunction (ED) is an almost unavoidable complication of radical prostatectomy. At present, though the concept of penile rehabilitation (PR) is accepted by most clinicians, the outcomes of erectile function recovery vary widely. Prostacyclin (PGI2) is a prostanoid and a main vasoprotectant which induces smooth muscle relaxation, but not used for replacement therapy because of its high unstability. SuperEnzyme is capable of continuous, specific and targeted promotion of PGI2 synthesis, and helps PR in ED patients after radical prostatectomy. SuperEnzyme gene therapy has a promising prospect for PR and the management of ED. This review updates SuperEnzyme gene therapy in PR.

Missed testicular torsion presenting with male infertility and erectile dysfunction / 中华男科学杂志

Testicular torsion has been estimated to affect 1 in every 4 000 males younger than the age of 25 years and has peaks of incidence occurring in the neonate and the adolescent entering puberty. The incidence of missed testicular torsion was about was 4%. The incidence of missed non-simultaneous bilateral torsion was unknown. We presented a case of missed bilateral testicular torsion with resulting primary testicular failure and hypogonadism with erectile dysfunction. The patient was seen for infertility and erectile dysfunction 10 years after the testicular torsion. Semen analysis revealed azoospermia. Serum total testosterone was at the castration level (0.14 nmol/L). His infertility was irreversible. His erectile dysfunction was managed successfully with testosterone replacement and use of sildenafil.
