Recent technological development of penile prosthesis: a literature review.

Background and Objective: In contemporary Urology, the gold standard for treatment of erectile dysfunction refractory to medical therapy has been implantation with a penile prosthesis. The past 40 years has witnessed evolutions in technology and surgical techniques, which have led to increased patient satisfaction rates and decreased complication and infection rates. This review is an update to a prior review article that evaluates these advancements in the context of patient satisfaction and different rates of complications following surgeries. In addition, the review compares malleable and inflatable prostheses with regard to infection rate, mechanical failure rate, and erosion rate. Methods: A literature search was conducted using Medline and Google Scholar to examine papers from 1973 to the present day. Keywords, such as, "penile prosthesis surgery", "malleable penile prosthesis", "inflatable penile prosthesis", "two-piece Inflatable Penile Prosthesis (IPP)", and "three-piece IPP" were utilized during the search. A total of 76 papers were included, and all were in English. Key Content and Findings: Studies on the latest models of each of the three prostheses (malleable, two-piece IPP, three-piece IPP) revealed patient satisfaction ratings at or above 75%. Both types of IPPs were associated with greater satisfaction and lower erosion rates while malleable prostheses were associated with lower mechanical failure rates. Although no significant differences in infection rates were noted between the prosthesis types, a history of diabetes, obesity, and smoking were predictive of infection events. Conclusions: The three-piece IPP, if indicated for a suitable patient, is generally accepted as the best type of prosthesis given its biological mimicry to an erect human penis.

Clomiphene Citrate in the Management of Infertility in Oligospermic Obese Men with Hypogonadism: Retrospective Pilot Study.

Background and Objectives: Obesity is a significant risk factor for hypogonadism and infertility that is further associated with reduced semen quality. The aim of this study is to evaluate the effect of clomiphene citrate (CC), prescribed for treating infertility, on serum testosterone and semen parameters, particularly in oligospermic obese hypogonadal men. Materials and Methods: A retrospective analysis of data related to men (n = 53) who underwent CC treatment for infertility and hypogonadism (testosterone < 300 ng/dL) was performed. Patients with obesity (BMI ≥ 30 kg/m2) and sperm concentration ≤ 15 × 106/mL were included for analysis. Results: The overall results showed that, in oligospermic obese men (n = 31), treatment with CC significantly improved baseline sperm concentration (4.5 ± 6.8 × 106/mL vs. 11.4 ± 15.5 × 106/mL, p < 0.05) and motility (31.5% ± 21.5% vs. 42.6% ± 14.7%, p < 0.05). Furthermore, subsequent examination of oligospermic hypogonadal obese men treated with CC (n = 13) revealed substantial improvements in baseline serum testosterone levels (193.8 ± 59.3 ng/dL vs. 332.7 ± 114.8 ng/dL, p < 0.05) along with an increase in sperm concentration, total motility, and normal morphology. Conclusions: The results of this retrospective study suggest that CC treatment not only improves chances of fertility outcomes by substantially improving semen parameters but also increases total serum testosterone levels in oligospermic obese men without any supplemental and expensive testosterone replacement therapy.

Hyperthyroidism as an Underlying Cause of Premature Ejaculation.

INTRODUCTION: Hormonal imbalances have been associated with various sexual dysfunction disorders. In particular, the connection of hyperthyroidism has been discovered to correlate to premature ejaculation (PE) but has yet to been thoroughly elucidated. As one of the most frequently self-reported sexual dysfunctions, it is imperative for health care professionals to evaluate possible underlying conditions in regard to treatment options for individuals with PE. OBJECTIVES: To review the literature regarding hyperthyroidism effects on sexual dysfunction, with a focus on hyperthyroidism and PE. METHODS: A literature review of articles and clinical studies was performed to define the classification, pathophysiology, diagnostic considerations, and management of hyperthyroidism on PE. Search terms included "hyperthyroidism" and/or "premature ejaculation," "treatment of premature ejaculation," "defining premature ejaculation," and "management of premature ejaculation." RESULTS: To improve the accuracy of diagnosing PE, there needs to be a set definition amongst the different guidelines, as using these guidelines can help determine possible underlying etiologies of PE. The correlation of hyperthyroidism and PE has been described in a limited number of studies. It has been reported that individuals with hyperthyroidism are much more likely to have PE than individuals with euthryoidism. Management of hyperthyroidism has been shown to alleviate the symptoms of PE. CONCLUSION: Further understanding of hyperthyroidism as an underlying cause of PE could lead to increased efficacy of treatment and management of PE. Tannenbaum J, Youssef M, Attia AS, et al.

Do Minimally Invasive Benign Prostatic Hyperplasia Treatments Preserve Sexual Function? A Contemporary Review of the Literature.

PURPOSE OF REVIEW: The aim of this study is to compare the sexual function outcomes related to minimally invasive surgical therapies (MISTs) (UroLift®, Rezum™, Aquablation®, prostate artery embolization, and iTind®) for the treatment of benign prostatic hyperplasia (BPH). RECENT FINDINGS: Clinical trials and retrospective data evaluating MISTs for BPH have demonstrated improved or stable sexual function outcomes when compared to sham control or transurethral resection of the prostate. Outcomes were assessed at baseline and following treatments using patient-reported outcome measures. Rezum and Aquablation demonstrated preservation of overall ejaculatory function and erectile function at 36-month follow-up. Similar outcomes occurred with UroLift after a 60-month follow-up. Erectile function was preserved following prostate artery embolization and iTIND up to 12 months. MIST for the management of BPH has been demonstrated to be effective in improving urinary function and appears to minimize potential collateral damage on sexual function following treatment.

Penile reconstruction: An up-to-date review of the literature.

OBJECTIVE: : To review the literature on adult penile reconstruction due to Peyronie's disease, trauma and cosmesis, while emphasising specific surgical techniques and procedures such as phalloplasty, radial forearm free flap reconstruction, and penile transplant. METHODS: : A comprehensive review of the literature for the years 1992-2020 of the PubMed and SpringerLink databases was performed to identify articles on penile reconstruction. Search terms included 'penile reconstruction', 'penile trauma', 'phalloplasty', 'penile transplant', and 'treatment of Peyronie's'. Relevant articles were selected. All included studies were performed on adults and written in English. RESULTS: : We were able to identify 46 papers from PubMed and SpringerLink that included the research terms. From these, we included technical details of procedures and gleaned photographs of their works. Additionally, we included photographs from our institution's own plication surgery cases. CONCLUSIONS: : The field of adult penile reconstruction is performed for a plethora of reasons. From cosmetic to urgent and from routine to complex, it is most certainly a growing subset of Urology that plays a vital role for the men who need it. To our knowledge, this is the most up-to-date review of adult penile reconstruction.
