Background: Daily (once a day [OaD]) tadalafil intake is a valuable option for men favoring spontaneous over scheduled sexual intercourse.

Aim: The study sought to assess the rate of and the clinical factors associated with spontaneous, medication-free erectile function (EF) recovery after discontinuation of tadalafil 5 mg OaD in a cohort of young men seeking first medical help for psychogenic erectile dysfunction (ED) as their primary complaint.

Methods: Data from 96 consecutive patients <50 years of age seeking first medical help for ED and prescribed tadalafil 5 mg OaD were analyzed. Patients completed the International Index of Erectile Function (IIEF) and underwent baseline penile color Doppler ultrasound. Follow-up involved clinical assessments or phone interviews. Spontaneous medication-free EF recovery was defined as IIEF EF domain score >22 after tadalafil discontinuation, prompting cessation of follow-up. Descriptive statistics compared tadalafil OaD responders and nonresponders. Cox regression hazard models explored the association between baseline characteristics and EF recovery risk post-drug discontinuation. Kaplan-Meier analyses estimated EF recovery probability over time.

Outcomes: The primary outcome was EF recovery after discontinuation of tadalafil 5 mg OaD.

Results: Overall, median age was 39 (interquartile range [IQR], 32-45) years. Of all, 82 (85.4%) patients achieved EF recovery after tadalafil OaD discontinuation, while 14 (14.6%) patients were identified as nonresponders. Median tadalafil usage time (from beginning to discontinuation) was 3 (IQR, 2-11) months. The most common treatment-emergent adverse event was headache in 9 (9.4%) patients. Nonresponders were older (43 [IQR, 42-45] years vs 38 [IQR, 31-44] years; P = .03), had higher body mass index (25.5 [IQR, 23.4-29.9] kg/m2 vs 23.6 [IQR, 21.8-25.9] kg/m2; P = .04), and reported lower baseline IIEF EF domain scores (12 [IQR, 7-15] vs 15 [IQR, 10-22]; P = .02) than responders. Nonresponders and responders did not differ in terms of baseline ED severity, Charlson comorbidity index, smoking, alcohol consumption, regular physical exercise, and color Doppler ultrasound parameters. Upon Cox regression analysis, younger age (hazard ratio, 0.95; 95% confidence interval, 0.92-0.99; P = .01) was associated to EF recovery, after adjusting for baseline ED severity, body mass index, smoking, and Charlson comorbidity index ≥1. The Kaplan-Meier analysis displays the probability of EF recovery over time, indicating rates of 43%, 60%, and 72% at 3-, 6-, and 12-month follow-up intervals, respectively.

Clinical implications: Tadalafil 5 mg OaD is an effective short-term treatment for psychogenic ED, allowing its discontinuation after achieving a normal medication-free EF.

Strengths and limitations: The main limitations are the lim

Background: Major ischemic priapism (IP) is defined as a persistent penile erection for >4 hours. IP may cause serious complications, especially if prompt resolution is not achieved. Therefore, selecting the most effective and usable shunt technique is crucial in IP cases that are refractory to medical therapy.

Aim: To compare the effectiveness and complication risks of distal corporoglanular shunt procedures with and without the Burnett "snake" maneuver.

Methods: We conducted a retrospective study of patients who presented with IP and underwent surgical treatment at our institution between 2005 and 2021. The patients were categorized into 2 groups: group 1 (n = 26) underwent distal shunt + Burnett snake maneuver, and group 2 (n = 56) underwent distal shunt-only. Clinical history, parameters of IP, details of medical and surgical treatments, and follow-up information were evaluated.

Outcomes: Outcomes included differences in IP resolution and recurrence, functional erections, and complications between corporoglanular shunt procedures with and without the Burnett snake maneuver.

Results: In group 1, 24 of 26 patients (92.3%) experienced priapism resolution with a single surgical intervention, while this outcome was observed in 30 of 56 patients (53.6%) in group 2 (P < .001). Notably, priapism recurrence was significantly lower in group 1, occurring in 1 of 24 patients (4.2%), as opposed to 8 of 30 patients (26.6%) in group 2 (P < .001). Of the patients with documented sexual function status at follow-up, functional erections (capable of penetration with or without phosphodiesterase 5 inhibitors) were noted in 6 of 14 patients (42.8%) in group 1 and 13 of 26 patients (50%) in group 2 (P = .66).

Clinical implications: This study provides valuable insights regarding technical aspects of distal shunt procedures with and without the Burnett snake maneuver for treating major IP episodes. These results can help surgeons with clinical decision making for patients who present with IP.

Strength and limitations: Limitations include the single-site retrospective design with potential selection bias, inaccuracies in medical record data, challenges in controlling confounding variables, and the lack of validated questionnaire scores for erectile function evaluation.

Conclusion: Our study demonstrates that modifying distal shunt procedures using the Burnett snake maneuver significantly improves priapism resolution and effectively prevents further priapism episodes without introducing additional complications or erectile function loss, thereby distinguishing it from distal shunt-only procedures.

Background: Vasculogenic erectile dysfunction is the most common type of erectile dysfunction, and penile Doppler ultrasound (PDUS) is a useful tool to assess erectile hemodynamics in the clinician's effort to discuss prognosis and management strategies with the patient.

Aim: We herein describe the PDUS protocol used at our center, including indications, technique, and data interpretation.

Methods: We describe our institutional experience with PDUS and discuss it in the context of a contemporary review of the literature for this investigation.

Outcome: Our institutional PDUS protocol.

Results: To perform PDUS properly, adequate training, equipment, setting, technique, and interpretation are critical. The accuracy of PDUS is entirely predicated on achieving complete cavernosal smooth muscle relaxation. A redosing protocol optimizes the reliability and reproducibility of the hemodynamic data acquired during PDUS. A rigidity-based assessment is performed, and patients are scanned according to the erection rigidity achieved (full hardness) or by administration of maximum dose of the vasoactive agent. Peak systolic velocity is considered a measure of arterial inflow (normal, >30 cm/s), while end diastolic velocity evaluates the veno-occlusive mechanism (normal, <5 cm/s). After the procedure, the patient is evaluated to confirm detumescence. If the patient has a persistent penetration rigidity erection, intracavernosal phenylephrine is administered; however, if detumescence is not achieved with intracavernosal phenylephrine injections alone, corporal aspiration is potentially performed.

Conclusion: PDUS is a valuable minimally invasive tool for erectile hemodynamics assessment and an accurate assessment of such, provided that complete cavernosal smooth muscle relaxation is achieved.

Background: Although sexual life and its knowledge are still taboo in many cultures, especially for women, it can negatively affect women's sexual health.

Aim: The aim of this study was to examine the relationship between the frequency and duration of masturbation and the sexual health literacy among young Muslim women of reproductive age between 18 and 25 years living in western Turkey.

Methods: The cross-sectional descriptive study was conducted with 921 young women in western Turkey between March and December 2023. Participants were included in the study per the snowball method. The data consisted of attitudes, beliefs, and behaviors regarding masturbation, sexual life, and sexual health literacy. Data were obtained on an online platform and analyzed with SPSS (version 24; IBM). Difference, correlation, and regression analyses were performed. The significance level for statistical analyses was accepted as P < .05.

Outcomes: The outcomes of the study are the attitudes, beliefs, and behaviors regarding masturbation, orgasm, sexual health literacy, and sexual function in women.

Results: The participants were young Muslim women aged 21.00 ± 1.89 years (mean ± SD). The frequency of masturbation was 5.06 ± 2.03 times per month, and the duration was 3.47 ± 1.77 minutes per day. Masturbation frequency and duration were significantly associated with sexual health literacy and sexual function (P < .001). According to regression analysis, sexual function increased and sexual health literacy increased as masturbation frequency and duration increased (P < .001).

Clinical implications: This study presents results on the current situation regarding the sexual health literacy and sexual lives in women from different geographies and cultures, and it serves as a source for future studies on areas that need to be improved.

Strengths and limitations: The limitation of the study is that it was conducted only with Muslim and Turkish women who use smartphones and are sexually active, so it cannot be generalized to all women. The strengths of the study are that it was conducted with a sample of 921 women, it was based on self-report and addressed many dimensions related to masturbation and female sexuality, and the results were reached through exploratory analysis.

Conclusion: The study found that the higher the duration and frequency of masturbation in young women, the better their sexual function and higher their sexual literacy.

Background: Diabetes mellitus commonly causes endothelial cell and smooth muscle cell death in penile cavernous tissue.

Aim: The study sought to study the mode of cell death in the penile cavernous tissue in type 1 diabetic rats.

Methods: A total of 36 Sprague Dawley rats 10 weeks of age were randomly divided into 2 groups: a normoglycemic group and type 1 diabetic group (intraperitoneal injection of Streptozotocin (STZ), 60 mg/kg). We randomly selected 6 rats from each group for tests at the end of 11, 14, and 18 weeks of age, respectively. All rats were able to eat and drink freely. The ratio of maximum intracavernous pressure to mean arterial pressure, concentration of serum testosterone, level of nitric oxide in the penile cavernosum, and expression of active caspase-1 (pyroptosis) and active caspase-3 (apoptosis) were determined.

Outcomes: At the end of weeks 4 and 8 of type 1 diabetes, the proportions of endothelial cells and smooth muscle cells undergoing apoptosis and pyroptosis in penile cavernous tissue are different.

Results: The ratio of maximum intracavernous pressure to mean arterial pressure and nitric oxide levels were significantly lower in the 4- and 8-week diabetic groups than in the normoglycemic group (P < .01). Penile endothelial cell pyroptosis (5.67 ± 0.81%), smooth muscle cell apoptosis (23.72 ± 0.48%), total cell pyroptosis (9.67 ± 0.73%), and total apoptosis (10.52 ± 1.45%) were significantly greater in the 4-week diabetic group than in the normoglycemic group (P < .01). The proportion of endothelial cell pyroptosis (24.4 ± 3.69%), endothelial cell apoptosis (22.13 ± 2.43%), total cell pyroptosis (14.75 ± 0.93%), and total apoptosis (14.82 ± 1.08%) in the penile tissues of the 8-week diabetic group were significantly greater than those in the normoglycemic group (P < .01).The 8-week survival proportions of diabetic endothelial cells (38.86 ± 8.85%) and smooth muscle cells (44.46 ± 2.94%) was significantly lower than the 4-week survival proportions of endothelial cells (93.17 ± 8.07%) and smooth muscle cells (75.12 ± 4.76%) (P < .05).

Clinical translation: Inhibition of cell death by different methods at different stages may be the key to the treatment of type 1 diabetes-induced erectile dysfunction.

Strengths and limitations: The effect of type 1 diabetes on other types of cell death in penile cavernous tissue needs further study.

Conclusion: The mode of death of endothelial cells in the cavernous tissue of the penis in the early stage in diabetic rats is dominated by pyroptosis, and the death of smooth muscle cells is dominated by apoptosis. Endothelial cell and smooth muscle cell death are not consistent at different stages of diabetes progression.

Background: Vaginal laxity (VL) is a complaint of excessive vaginal looseness with a prevalence ranging from 24% to 38% across studies.

Aim: The study sought to compare the effect of radiofrequency (RF) and pelvic floor muscle training (PFMT) on the treatment of women with VL.

Methods: From February 2020 to December 2021, a prospective, parallel, noninferiority, randomized clinical trial was carried out in women ≥18 years of age and complaining of VL in a tertiary hospital. Two groups (RF and PFMT) were evaluated at the beginning of the study and 30 days and 6 months postintervention. A total of 42 participants per arm was sufficient to demonstrate a difference in sexual function on the Female Sexual Function Index at 90% power, 1-sided type 1 error of 0.025 with a noninferiority margin of 4 on the FSFI total score. Analysis was intention-to-treat and per-protocol based.

Outcomes: The primary endpoint was the change of FSFI score after treatment, and the secondary outcomes were improvement in symptoms of VL and changes in questionnaire scores of sexual distress, vaginal symptoms, and urinary incontinence, in the quantification of pelvic organ prolapse, and pelvic floor muscle (PFM) contraction.

Results: Of 167 participants recruited, 87 were included (RF: n = 42; PFMT: n = 45). All questionnaires improved (P < .05) their total scores and subscales in both groups and during the follow-ups. After 30 days of treatment, RF was noninferior to PFMT to improving FSFI total score (mean difference -0.08 [95% confidence interval, -2.58 to 2.42]) in the per-protocol analysis (mean difference -0.46 [95% confidence interval, -2.92 to 1.99]) and in the intention-to-treat analysis; however, this result was not maintained after 6 months of treatment. PFM contraction improved significantly in both groups (RF: P = .006, 30 days; P = .049, 6 months; PFMT: P < .001, 30 days and 6 months), with better results in the PFMT group.

Clinical implications: Sexual, vaginal, and urinary symptoms were improved after 30 days and 6 months of treatment with RF and PFMT; however, better results were observed in the PFMT group after 6 months.

Strengths & limitations: The present randomized clinical trial used several validated questionnaires evaluating quality of life, sexual function and urinary symptoms, in addition to assessing PFM contraction and classifying the quantification of pelvic organ prolapse aiming at anatomical changes in two follow-up periods. The limitations were the lack of a sham-controlled group (third arm) and the difficulty of blinding researchers to assess treatments due to the COVID-19 pandemic.

Conclusion: After 30 days and 6 months of treatment, sexual, vaginal, and urinary symptoms improved with RF and PFMT; however, better results were observed in the PFMT group after 6 month
