Penile size is closely concerned and short penis contributes serious sexual dysfunction and tremendous psychological problems to couples. Androgen is essential for penile development and testosterone replacement is recommended to patients with micropenis. We previously proved that inhibiting activity of lysyl oxidase (Anti-lysyl oxidase, Anti-LOX) combined with vacuum erectile device (VED) lengthened penis by remodeling tunica albuginea. We thus explored whether HCG supplement could accelerate tunica albuginea remodeling (induced by Anti-LOX + VED) to promote penile growth. Forty-two SD male rats (4 weeks old) were purchased and divided into 7 groups: control, Anti-LOX, HCG, VED (with a negative aspirated pressure of - 300 mmHg), Anti-LOX + VED, HCG + VED, and Anti-LOX + HCG + VED. After an intervention for 4 weeks, all rats' penile length, exposed penile length, and erectile function were measured. Serum samples were collected to detect hormone levels and penile corpus cavernosum were harvested for histo-pathological analysis. All intervention groups showed significantly longer penis than controlled rats. Anti-LOX sharply increased penile length and exposed length by 15% and 9% respectively, this lengthening effect was more obvious in Anti-LOX + VED group (26% and 19%, respectively). Although HCG promoted penile length by 8%, this effect was slight for exposed length (3%). Moreover, Anti-LOX + HCG + VED dramatically increased penile length and exposed length by 22% and 18%, respectively, which was similar with that in Anti-LOX + VED (26% and 19%, respectively). HCG dramatically stimulated testosterone and dihydrotestosterone secretions than control group, whether with or without Anti-LOX and VED; while it induced more AR expression than other groups. Finally, all procedures did not improve or deteriorate normal erectile function. Although we verified that Anti-LOX + VED lengthened penis by inducing tunica albuginea remodeling, however, HCG supplement did not synergize with Anti-LOX + VED to accelerate albuginea remodeling to facilitate penile growth.

KEY CLINICAL MESSAGE
High-flow priapism in pediatric population is rare, yet comprehensive clinical evaluation, along with penile Doppler ultrasound, and cavernosal blood analysis are crucial for accurate diagnosis. Conservative therapy is effective as an initial treatment.
ABSTRACT
High-flow priapism is considerably rare in the pediatric age group. We report a four-month-old infant presented with a prolonged penile erection. Diagnostic confirmation was achieved through the utilization of Doppler ultrasound and cavernous blood gas analysis. We also review published data on the management of this condition.

Review
Genital gender affirmation surgery (gGAS) for individuals assigned female at birth (AFAB) is complex and requires the staged insertion of an erectile device to permit penetrative intercourse. This final stage of gGAS is challenging, owing to the variable anatomy and lack of supportive structures within the neophallus when compared with erectile device insertion for individuals assigned male at birth. There is a paucity in the literature at present regarding erectile device insertion in trans-sex AFAB patients. Hence, a narrative review following a literature review and supplemented by expert opinion from a high-volume centre of expertise is presented. The choices available for erectile device in this patient cohort are discussed. Principle surgical steps required for this complex surgery is outlined along with the recommended postoperative management of the patient. Postoperative outcomes and complications are also summarised in this fast-developing surgical procedure.

BACKGROUND
Penoscrotal constriction devices are either used as autoerotic stimuli or to increase sexual pleasure or performance by maintaining an erection for a longer period, and a variety of metallic and non-metallic objects are used. On the other hand, penile strangulation is a rare urologic emergency that requires prompt evaluation and intervention to prevent long-term complications. The goal of treating penile incarceration is to remove the foreign object as soon as possible. On the other hand, removal can be very challenging, and often requires resourcefulness and a multidisciplinary approach.
CASE SUMMARY
A 47-year-old man who has sex with men was transferred to our hospital for persistent phallodynia and scrotal pain, accompanying swelling due to strangulation by stainless steel rings. His medical history included acquired immunodeficiency syndrome. One day prior, he had put three stainless steel rings on his penis and scrotum before sexual intercourse. After sexual intercourse, he was unable to remove them, due to swelling of his penis and scrotum. The swelling persisted, and he felt pain in the affected area the next day, then he was transferred to our hospital by ambulance. The emergency department found that his penis and scrotum were markedly engorged and swollen. We established a diagnosis of penile and scrotal strangulation by stainless steel rings. We unsuccessfully attempted to cut the rings using a cutter, then requested a rescue team emergency medical service. They cut through each ring in two places, using an electric-powered angle grinder, and successfully removed all of the pieces. Finally, he was discharged and went home.
CONCLUSION
We report the first case of penile and scrotal strangulation by stainless steel rings in an human immunodeficiency virus positive person.

Penile rings have been used to help sustain erection and enhance sexual pleasure for centuries. Constriction of the penis reduces the outflow of blood from the cavernosal tissue. However, if left for an extended time period, a condition called penile ring entrapment can occur. This may result in severe edema, gangrene, necrosis, and even penile amputation. Penile ring entrapment is a very rare condition; complete urinary obstruction with concomitant bladder rupture as a result renders this case even more extraordinary. We discuss our experience in the management of a 64-year-old man, who presented with altered mental status and inability to urinate, found to have penile ring entrapment and intraperitoneal bladder rupture. Removal of the constricting ring was performed in the ED, and bladder injury and penile necrosis were subsequently repaired with robot-assisted laparoscopic cystorrhaphy, penectomy, and perineal urethrostomy.

Malignant priapism (MP) is defined as a condition of persistent erection of the penile without sexual stimulation due to malignant cell invasion to the cavernous sinus and the efferent veins. We present a case of a man, 63 years old, with previous history of high-grade renal carcinoma pT3N0M0 had been through radical nephrectomy, diagnosed with MP secondary from metastatic renal carcinoma. The management of this case was aspiration of corpora cavernosa and distal shunting with the Al-Ghorab procedure, then continued to total penectomy and perineostomy.

This study aimed to investigate the impact of the coronavirus disease 2019 (COVID-19) pandemic on erectile function in Chinese patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). A retrospective study was conducted on 657 CP/CPPS patients who visited The Third Xiangya Hospital of Central South University (Changsha, China) from November 2018 to November 2022. Patients were divided into two groups based on the timeline before and after the COVID-19 outbreak in China. The severity of CP/CPPS, penile erection status, anxiety, and depression was evaluated using the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI), International Index of Erectile Function-5 (IIEF-5), Generalized Anxiety Disorder-7 (GAD-7), and Patient Health Questionnaire-9 (PHQ-9) scales, respectively. Compared with patients before the COVID-19 outbreak, more CP/CPPS patients developed severe erectile dysfunction (ED) due to depression and anxiety caused by the pandemic. After developing moderate-to-severe ED, mild and moderate-to-severe CP/CPPS patients exhibited more apparent symptoms of anxiety and depression ( P < 0.001 and P = 0.001, respectively), forming a vicious cycle. The COVID-19 pandemic has adversely affected the psychological status of CP/CPPS patients, exacerbating their clinical symptoms and complicating ED. The exacerbation of clinical symptoms further worsens the anxiety and depression status of patients, forming a vicious cycle. During the COVID-19 pandemic, paying more attention to the mental health of CP/CPPS patients, strengthening psychological interventions, and achieving better treatment outcomes are necessary.

Erectile dysfunction (ED) caused by cavernous nerve injury (CNI) is refractory to heal mainly ascribed to the adverse remodeling of the penis induced by ineffectual microvascular perfusion, fibrosis, and neurotrophins scarcity in cavernosum. Phosphodiesterase type V inhibitors (PDE5i) have been regarded as an alternative candidate drug for avoiding penile neuropathy. However, the therapeutic efficacy is severely limited due to poor accumulation under systemic medication and endogenous nitric oxide (NO) deficiency in cavernosum. Herein, an innovative liposomal microbubble (MB) loaded with both Sildenafil (one of PDE5i) and NO was designed. Ultrasound-targeted MB destruction (UTMD)-mediated efficient release and integration erectogenic agents into corpus cavernosum with high biosafety. On a bilateral CNI rat model, the multifunctional MB-cooperated UTMD improved microvascular perfusion in penis, simultaneously, alleviated hypoxia and oxidative stress, indicating successful activation of NO-cyclic guanosine monophosphate pathway. Also, evaluation of the endothelial/muscular composition, intracavernosal pressure, and neural integrity in the penis proved that coordinated intervention reversed the abnormal structural remodeling and promoted the recovery of functional erection. Our work demonstrates that MB loading Sildenafil and NO combined with UTMD hold great promise to "awaken" the efficacy of PDE5i in neurogenic ED, which provided a superior option for ensuring penile rehabilitation.

The traditional use of L. roots to enhance male sexual performance prompted us to assess the in silico, in vitro, and in vivo aphrodisiac activities of its hydroethanolic extract using normal male rats. Spectroscopic characterization indicated the presence of ß-D-glucopyranoside, methyl-1,9-benzyl-2,6-dichloro-9H-purine, and Bis-(2-ethylhexyl)-phthalate; these compounds have a significant inhibitory effect on the phosphodiesterase-5 (PDE-5) enzyme in silico evaluation and minerals (including zinc, cadmium, and magnesium). Other phytochemical analyses revealed the presence of phenolic compounds and flavonoids. These phytochemicals and minerals may contribute to the aphrodisiac activities of the extract. Additionally, the in vivo study revealed that the administration of root extract (300 mg/kg) significantly enhanced ( < 0.01, < 0.03) mount, intromission, and ejaculation frequencies while significantly ( < 0.05) decreasing the mount and intromission latencies, as well as the post-ejaculatory interval time, in comparison with the standard drugs sildenafil and ginseng, resulting in enhanced erection and sexual performance in the rats. Furthermore, the extract significantly ( < 0.05) increased penile reflexes and also elevated the levels of testosterone and luteinizing hormones. Extract (300 mg/kg) significantly ( < 0.05) inhibited the PDE-5 enzyme in an in vitro study. Concludingly, the comprehensive findings of this study suggest that a standardized herbal extract derived from roots alleviates erectile dysfunction and premature ejaculation in male rats. root extract proved to be an alternative treatment for erectile dysfunction and premature ejaculation.
