Precise spatiotemporal control of physiological processes by optogenetic devices inspired by synthetic biology may provide novel treatment opportunities for gene- and cell-based therapies. An erectile optogenetic stimulator (EROS), a synthetic designer guanylate cyclase producing a blue-light-inducible surge of the second messenger cyclic guanosine monophosphate (cGMP) in mammalian cells, enabled blue-light-dependent penile erection associated with occasional ejaculation after illumination of EROS-transfected corpus cavernosum in male rats. Photostimulated short-circuiting of complex psychological, neural, vascular, and endocrine factors to stimulate penile erection in the absence of sexual arousal may foster novel advances in the treatment of erectile dysfunction.

Purpose: To investigate the therapeutic potential of eliminating insulin-like growth factor-binding protein 5 (IGFBP5) expression in improving erectile function in mice with cavernous nerve injury (CNI)-induced erectile dysfunction (ED).

Materials And Methods: Eight-week-old male C57BL/6 mice were divided into four groups: a sham-operated group and three CNI-induced ED groups. The CNI-induced ED groups were treated with intracavernous injections 3 days before the CNI procedure.

LN18178 is a standardized, synergistic combination of fruit rind and seed extracts, which has been reported to increase serum testosterone levels in young and aging males. The present 84-day randomized, double-blind, placebo-controlled study assessed the efficacy of LN18178 on the sexual function of aging male volunteers (age: 40-70 years; serum total testosterone: ≥ 300 ng/dL). The subjects with mild to moderate erectile dysfunction [5-item version of the International Index of Erectile Function (IIEF-5) scores 17-25] and low sexual desire (score < 3 on items 11 and 12 of IIEF) participated in this investigation.

Erectile dysfunction (ED) is a pathophysiological condition in which the patients cannot achieve an erection during sexual activity, and it is often overlooked yet prevalent among diabetic men, globally affecting approximately 35-75% of diabetic individuals. The precise mechanisms through which diabetes contributes to ED remain elusive, but the existing literature suggests the potential involvement of nerve and vascular damage that affects the penile supply. In the present review, we reanalyze the existing human single-cell transcriptomic data from patients having diabetes mellitus-associated ED with normal erections.

The reliable engraftment of skin grafts into areas with complex shapes can be challenging. Here, we report a case of successful fixation of a genital skin graft using negative pressure wound therapy (NPWT) with RENASYS Cotton Filler. A 44-year-old male with no relevant medical history underwent split-thickness skin grafting for a genital skin defect caused by Fournier's gangrene.

Background: The penile suspensory ligament (PSL) plays a significant role in penile support and erection and its injury or congenital absence may result in functional impairment of erectile function.

Aim: To describe the diagnosis and surgical repair technique for PSL abnormalities and overall outcomes.

Methods: A comprehensive review of the literature was performed to understand the anatomic relevance of the PSL and historical management of PSL defects.
