Incidence of prostate, colorectal and male breast cancers in relation with statins and testosterone replacement therapy: SEER-Medicare 2007-2015.

Introduction: Statins and testosterone replacement therapy (TTh) have been inconsistently associated with a reduced risk of hormone-related cancers (HRCs, prostate [PCa], colorectal [CRC], and male breast cancers [BrCa]). Yet, the joint association of statins and TTh with the incidence of these cancers, and whether these associations vary by race, remains poorly understood. The objective of this retrospective cohort study is to examine the independent and joint effects of pre-diagnostic use of statins and TTh on the risk of HRCs, including PCa, CRC, and male BrCa.

A population analysis of delayed ejaculation using a claims database: characteristics and national trends in prevalence, incidence, and pharmacotherapy.

We investigated the prevalence, incidence, and rates of pharmacological treatment of delayed ejaculation using the TriNetX Diamond Network. We included all men evaluated in the inpatient, outpatient, and emergency settings. Prevalence was determined by comparing the number of men diagnosed with delayed ejaculation to the entire population.

Hard-Flaccid syndrome: a survey of sexual medicine practitioners' knowledge and experience.

Hard-flaccid syndrome (HFS) is a poorly understood condition of male sexual dysfunction (MSD) that has more recently become a new topic of discussion in online forums and sexual medicine conferences. There has been limited research looking into HFS and consequently there are no evidence-based guidelines for its work-up and management. In order to identify the current level of understanding of HFS in the sexual medicine community, a survey was distributed at a national urologic conference focusing on pertinent management strategies employed by practitioners, and their own thoughts on HFS.

Prescribing semaglutide for weight loss in non-diabetic, obese patients is associated with an increased risk of erectile dysfunction: a TriNetX database study.

Semaglutide was approved in June 2021 for weight loss in non-diabetic, obese patients. While package inserts include sexual dysfunction as a side effect, no study has assessed the degree of this risk. The objective of our study is to assess the risk of developing erectile dysfunction after semaglutide is prescribed for weight loss in obese, non-diabetic men.

Evaluating the impact of pre-diagnostic use of statins and testosterone replacement therapy on mortality outcomes in older men with hormone-related cancers: Surveillance, Epidemiology, and End Results-Medicare 2007-2015.

Background: The link between the pre-diagnostic use of statins and testosterone replacement therapy and their impact on hormone-related cancers, prostate cancer, colorectal cancer, and male breast cancer survival remains a topic of controversy. Further, there is a knowledge gap concerning the joint effects of statins and testosterone replacement therapy on hormone-related cancer survival outcomes.

Objective: To examine the independent and joint effects of pre-diagnostic use of statins and testosterone replacement therapy on the risk of all-cause and cause-specific mortality among older men diagnosed with hormone-related cancers, including prostate cancer, colorectal cancer, and male breast cancer.

Analysis of sexual dysfunction development among male and female living kidney donors.

Introduction: Living kidney donations (LKDs) face a persistent demand for patients with end-stage renal disease, emphasizing the importance of LKDs' growth and success. Although living kidney donors generally exhibit excellent survival rates, little research has explored the development of long-term sexual dysfunction following LKD.

Objectives: This study aimed to analyze differences in 5-year sexual dysfunction outcomes between male and female living kidney donors, utilizing the TriNetX database, a federated network of electronic medical records from multiple U.

A propensity score-matched analysis of intra- and postoperative penile prosthetic complications in the solid organ transplant population.

Introduction: Solid organ transplant (SOT) has an anticipated higher risk of penile prosthesis (PP) complications related to immunosuppression and surgical approach post-SOT. It is still not determined if PP surgery in the SOT population incurs these same higher risks.

Objectives: To observe differences in intra- and postoperative PP complications between SOT and non-SOT cases from the TriNetX US Collaborative Network, a large real-world database of deidentified patient data from 56 health care organizations within the United States.

Association of serum testosterone with chronic obstructive pulmonary disease (COPD) in a nationally representative sample of White, Black, and Hispanic men.

Background: The association between total testosterone (T) and chronic obstructive pulmonary disease (COPD), remains poorly understood. We aim to investigate this association and how it varies by smoking status, body fatness, and race/ethnicity in a nationally representative sample of American men.

Methods: Data included a full sample (NHANES 1988-1991, 1999-2004, 2011-2012) and subset sample (excluding 2011-2012, no estradiol and SHBG levels available) of 2748 and 906 men (≥20 years), respectively.

Association of total and free testosterone with cardiovascular disease in a nationally representative sample of white, black, and Mexican American men.

Grower or shower? Predictors of change in penile length from the flaccid to erect state.

In colloquial English, a "grower" is a man whose phallus expands significantly in length from the flaccid  to the erect state; a "shower" is a man whose phallus does not demonstrate such expansion. We sought to investigate various factors that might predict a man being either a grower or a shower. A retrospective review of 274 patients who underwent penile duplex Doppler ultrasound (PDDU) for erectile dysfunction between 2011 and 2013 was performed.

Objective: To compare in a prospective nonrandomized fashion, the outcomes of collagenase clostridium histolyticum (CCH) and surgical interventions (tunical plication [TP] and partial plaque excision and grafting [PEG]) in patients with Peyronie's disease (PD). Intralesional injection of CCH is the only Food and Drug Administration-approved nonsurgical intervention for PD.

Materials And Methods: Between June 2015 and January 2017, 57 patients with PD and dorsal, dorsolateral, and/or lateral penile curvatures 30°-90° were included in this study.

Penile Prosthesis Complications: Planning, Prevention, and Decision Making.

Introduction: Inflatable penile prosthesis (IPP) is an established treatment option for men with erectile dysfunction (ED) refractory to medical therapy. Standardization of surgical technique and improvements in device construction have reduced all-cause complication rates to less than 5% in recent reports. Nonetheless, complications do exist, and can strongly impact morbidity and the quality of life of patients.

Andrianne Mini-Jupette Graft at the Time of Inflatable Penile Prosthesis Placement for the Management of Post-Prostatectomy Climacturia and Minimal Urinary Incontinence.

Background: After radical prostatectomy (RP), erectile dysfunction, often necessitating the need for inflatable penile prosthesis (IPP) insertion, and urinary incontinence and climacturia can ensue.

Aim: To assess the efficacy and safety of the mini-jupette, a mesh used to approximate the medial aspects of the 2 corporotomies at the time of IPP insertion, for the management of climacturia and urine leakage in patients with minimal incontinence.

Methods: We conducted a pilot multicenter study of patients with post-RP erectile dysfunction and climacturia and/or mild urinary incontinence (≤2 pads/day [ppd]) undergoing IPP insertion with concomitant placement of a mini-jupette graft.

Role of Penile Prosthesis in Priapism: A Review.

Ischemic priapism is a urological emergency that has been associated with long-standing and irreversible adverse effects on erectile function. Studies have demonstrated a linear relationship between the duration of critically ischemic episodes and the subsequent development of corporal fibrosis and irreversible erectile function loss. Placement of a penile prosthesis is a well-established therapeutic option for the management of erectile dysfunction secondary to ischemic priapism, and will be the focus of this review.

Collagenase Clostridium Histolyticum in the Treatment of Peyronie's Disease: Review of a Minimally Invasive Treatment Option.

Peyronie's disease (PD) is an inflammatory disorder characterized by an abnormal collagen deposition in the tunica albuginea of the penis, leading to fibrous and non-compliant plaques that can impede normal erection. Although pharmacological treatments are available, only intralesional injection therapy and surgical reconstruction have demonstrated tangible clinical efficacy in the management of this condition. Intralesional injection of collagenase clostridium histolyticum (CCH) has come to the forefront of minimally invasive treatment of PD.

Penile Calciphylaxis: The Use of Radiological Investigations in the Management of a Rare and Challenging Condition.

Penile calciphylaxis is a rare phenomenon of penile necrosis observed in patients with hemodialysis-dependent end-stage renal failure. Multiple treatments have been proposed including conservative management, surgical debridement and penectomy; yet, the prognosis remains extremely poor. Here, we describe a patient with protracted resolution of dry gangrene of the glans, which failed conservative management of wound care and pain management.
