Non-invasive and surgical penile enhancement interventions for aesthetic or therapeutic purposes: a systematic review

Techniques for Penile Augmentation Surgery: A Systematic Review of Surgical Outcomes, Complications, and Quality of Life

The increase in practices related to enhancing penile size can be attributed to the belief that an improved genital appearance contributes to a man's virility, coupled with an altered self-perception of his body. It is crucial to tailor interventions to meet the genuine needs of patients by thoroughly assessing their history, psychological state, and potential surgical benefits, all while considering the associated risks of complications. This systematic review aims to summarize the available evidence on outcomes, complications, and quality of life after penile augmentation surgery, examining both minimally invasive and more radical techniques. A search of the PubMed and Scopus databases, focusing on English-language papers published in the last 15 years, was performed in December 2023. Papers discussing surgery in animal models and case reports were excluded from the present study unless further evaluated in a follow-up case series. The primary outcomes were changes in penile dimensions, specifically in terms of length and girth, as well as the incidence of surgical complications and the impact on quality of life. A total of 1670 articles were retrieved from the search and 46 were included for analysis. Procedures for penile length perceived enhancements include lipoplasty, skin reconstruction plasty, V-Y and Z plasty, flap reconstruction, scrotoplasty, ventral phalloplasty, and suspensory ligament release; techniques for increasing corporal penile length include penile disassembly, total phalloplasty, and sliding elongation. Finally, penile girth enhancement may be performed using soft tissue fillers, grafting procedures, biodegradable scaffolds, and Penuma®. In conclusion, while penile augmentation surgeries offer potential solutions for individuals concerned about genital size, the risks and complexities need to be accounted for.

#Penisenlargement on Instagram: a mixed-methods study

This study aims to analyze the reliability of #penisenlargement hashtag on Instagram and to investigate how young adult men perceive their penis size in real-world settings after being exposed to #penisenlargement Instagram postings. In the first phase, the credibility of the 100 most recent publicly accessible postings with the #penisenlargement hashtag was evaluated. Also, the last 1000 posts related to the same hashtag were evaluated to determine follower reach and engagement impacts. In the second phase, men were exposed to the #penisenlargement hashtag for 6 months and completed an online questionnaire examining their motives to undergo augmentation. Only a few (n = 6, 1%) posts had reliable information. At the time of questionnaire completion, participants reported a substantial drop in their genital self-image (22.3 ± 3.6 to 17.8 ± 3.0, p < 0.001) and a significant increase in their media exposure (1.24 ± 1.05 to 2.3 ± 0.74, p < 0.001) compared to their pre-Instagram exposure levels. The most prevalent reason for pursuing penis enlargement following Instagram exposure was to enhance self-perception and confidence. Our findings indicate that penis enlargement methods on Instagram are mostly unreliable. In addition, being exposed to posts pertaining to "penis enlargement" the hashtag can encourage men to seek penis augmentation surgery.

Intraplaque injections of hyaluronic acid for the treatment of stable-phase Peyronie's disease: a retrospective single-center experience

ABSTRACT

Peyronie's disease (PD) is a condition of penile connective tissue affecting up to 10% of men worldwide. In the complexity of its management, nonsurgical treatments, such as intraplaque injections, are gaining attention. The current literature shows data on the efficacy of intraplaque injections of hyaluronic acid (HA) mainly in acute-phase PD. However, data on injections of HA in stable-phase PD are lacking. Data for this retrospective study were derived from a prospectively maintained database of private patients presenting at a private medical practice affiliated to the University of Naples "Federico II" (Naples, Italy) with stable-phase PD between January 2020 and March 2023. Patients underwent a standard protocol of three injections, each administered at a two-week interval. During the intervals, patients performed vacuum device therapy, penile stretching, and modeling exercises. All patients compiled the Peyronie's Disease Questionnaire (PDQ) and Global Assessment of Peyronie's Disease (GAPD) at baseline and 2 weeks after the third injection. A penile Doppler ultrasound was performed 2 weeks after the last injection to record the final curvature. Overall, we recruited 62 patients with stable-phase PD and a mean (±standard deviation [s.d.]) curvature of 52.7° (±9.7°). After 6 weeks, eight (12.9%) patients did not experience any curvature improvement. The remaining 54 patients had a final mean (±s.d.) curvature of 40.3° (±9.1°) with P < 0.001, compared to that before treatment. We found improvement in all PDQ domains (all P ≤ 0.01), and 50 (80.6%) patients reported subjective improvement of the penile curvature according to the GAPD. In conclusion, we demonstrated that after three injections of HA administered according to the adopted protocol, patients with stable-phase PD could experience significant improvements in penile curvature, and physical and psychological consequences of the disease without significantly relevant side effects.

The Efficacy of Injection Penile Girth Enhancement as an Option for Small Penis Syndrome Management

BACKGROUND

In recent years aesthetic injection techniques with soft tissue fillers have become popular worldwide due to their effectiveness, safety, and low cost. There is no standard approach to the management and follow-up of patients seeking penile enlargement procedures described in the literature, and the surgical penile enlargement methods are controversial.

OBJECTIVES

The goals of this study were to assess the effect of injection penile girth enlargement on sexual relationship satisfaction, confidence, and self-esteem, and to evaluate the clinical efficacy and safety of this procedure for the management of men with small penis syndrome (SPS).

METHODS

This was a single-center, clinical case series study executed from January 2019 to February 2021, which involved 148 men who were unsatisfied with the shape of their normal-size penises and requested penis girth correction.

RESULTS

A total of 132 patients completed full treatment and follow-up. Mean girth enlargement was 1.7 ± 0.32 cm for the midshaft and 1.5 ± 0.32 cm for the glans of the penis. Satisfaction with sexual life improved. Mean scores increased by 17.9 ± 3.04 points for sexual relationship satisfaction and by 12.2 ± 3.17 points for confidence. The mean score for self-esteem increased by 8 ± 2.8 and by 4.3 ± 0.97 points for overall relationship satisfaction.

CONCLUSIONS

Penile enlargement with hyaluronic acid injection positively affects sexual relationship satisfaction, confidence, and self-esteem of men with SPS. The rate of psychosocial improvement does not correlate with penile size changes. It is a simple, safe, and effective technique that can be used in daily clinical practice.

Reconstruction Using a Scrotal Flap with Autologous Augmentation for Delayed Infection Caused by Penile Filler Injection: A Case Report

Penile augmentation using filler injections is gaining popularity; however, complications such as foreign body reactions can arise, leading to issues like penile ulceration and necrosis, subsequently necessitating reconstruction. The existing method of the reconstruction of the penis is primarily aimed at filling the deficit. In this paper, we describe a case in which a scrotal flap and autologous augmentation were utilized to treat a soft tissue defect caused by a delayed infection following a penile filler injection. The patient, a 41-year-old male, had received an Aquafilling® (Biomedica, Prague, Czech Republic) filler injection seven years earlier and later developed a delayed infection. After debridement, the penile defect spanned the entire shaft, and the circumference of the flaccid penis was 7.5 cm. Using a bilateral scrotal flap technique, the lower margins of both flaps were rolled inward after de-epithelialization to achieve autologous augmentation. Over the three-month post-surgery follow-up, neither infections nor flap necrosis were observed. The penile circumference increased to 12 cm, and the patient reported high satisfaction with the outcome. This new surgical technique can be widely applied as treatment for a variety of penile defects.

Size matters: characterizing penile augmentation content from the 100 most popular YouTube videos

Aesthetic penile augmentation is considered investigational and not shown to be safe or efficacious. This study sought to characterize the quality and reliability of YouTube videos on the topic of penile augmentation. A systematic search identifying the 100 most viewed YouTube videos on penile augmentation was conducted. The videos were then evaluated by two independent urologists for reliability and quality using a modified DISCERN scoring system and Global Quality Scale (GQS). The median total views were 530,612 (range 123,478-32,914,713). The median DISCERN and GQS scores for all 100 videos were generally poor at 1.75 (IQR 1-2.63) and 2.5 (IQR 1.5-3.5), respectively. A little under half of the videos had a physician present (44.7%). DISCERN and GQS scores were significantly higher in videos with physicians compared to those without one (p < 0.001 for both). The majority of videos discussed nonsurgical methods of penile augmentation (65.1%) with penile traction devices being the most frequently discussed (19.2%). Urologists and medical organizations should strive to have more of a presence in this space to ensure patients are appropriately educated and counseled before pursuing potentially ineffective or harmful treatments.

Complications and outcomes following injection of foreign material into the male external genitalia for augmentation: a single-centre experience and systematic review

Injection of exogenous material into the penis and scrotum has been performed for augmentation purposes. Complications include cosmetic dissatisfaction, penile necrosis and lymphoedema. We report the complications and outcomes from a single centre with an updated systematic review of the literature. A retrospective review of all cases presenting with foreign substance injection into the genitalia, over a 10-year period was performed. Thirty-five patients with a mean (standard deviation (SD); range) age of 36.9 (±9.1; 22-61) years at presentation were included. The mean (SD; range) time between injection and presentation was 7.8 (±5.8; 1 day-20 years) years. The most common injected substance was silicone (n = 16, 45.7%) and liquid paraffin (n = 8, 22.9%). The penile shaft (94.3%) was the most injected site. The most common presentations were cosmetic dissatisfaction (57.1%) and pain and/or swelling (45.7%). Surgery was required in 32 (91.4%) cases. Primary procedures included local excision and primary closure (n = 19, 59.4%), circumcision (n = 5, 15.6%), excision with a split skin graft or a scrotal flap reconstruction (n = 5, 15.6%). Three (8.6%) patients presented with necrosis and required acute debridement. Overall, 18 patients had more than 1 procedure, and 8 patients required 3 or more procedures. A systematic search of the literature identified 887 articles of which 68 studies were included for analysis. The most common substance injected was paraffin (47.7%), followed by silicone (15.8%). The majority of patients (77.9%) presented with pain, swelling or penile deformity. 78.8% of the patients underwent surgical treatment, which included excision and primary closure with or without the use of skin grafts (85.1% of all procedures), the use of flaps (12.3%) and penile amputation (n = 2). Complications of foreign body injection into the male genitalia can be serious resulting in necrosis and autoamputation. Surgical intervention is often required to excise abnormal tissue to manage pain and improve cosmesis.

Voice Assistants as Consultants for Male Patients with Sexual Dysfunction: A Reliable Option?

The aim of this study was to evaluate the ability of Google Assistant, Alexa, and Siri to recognize and answer questions about male sexual health. Each VA was tested on a smart speaker: Alexa on Amazon Echo Dot 4th Gen., Google Assistant on Google Home Mini, and Siri on Apple HomePod. A pool of patients' frequently asked questions regarding erectile dysfunction (ED), premature ejaculation (PE), Peyronie's disease (PD), male infertility, and other aspects of male sexual health were identified by authors. The recognition of question was evaluated ("yes" or "not"). For each recognized question, the response characteristics (domains) were rated on a scale from 0 to 10 (according to the quality). We chose the recognition rate of the questions as the primary outcome and the quality of the answers as the secondary outcome. Overall, the best VA in recognizing questions was Siri, with a total of 83.3% questions compared with 64.0% for Alexa (p = 0.024) and 74.0% for Google Assistant (p = 0.061). Siri was associated with a significantly higher recognition rate than Alexa for PE (80% vs. 40%; p = 0.002) and PD (66.7% vs. 33.3%; p = 0.010). The quality of the responses was classified as low in 57 out of 105 cases (54.3%), intermediate in 46 cases (43.8%), and high in only 2 cases (1.9%), highlighting an overall intermediate-low quality of the answers. Male infertility was the condition associated with the highest mean scores in "Targeted response to the problem" (7.32 ± 2.57), "Scientific correctness of the answer", (5.9 ± 2.76) "Completeness of the answer" (5.14 ± 2.56), and "Understandability of the response for a patient" (5.3 ± 2.51) domains. Siri was associated with significantly higher scores than Alexa (p < 0.05) in several domains of all conditions evaluated. The question recognition rate of VAs is quite high; however, the quality of the answers is still intermediate-low. Siri seems superior to Alexa in both question recognition and response quality. Male infertility appears to be the sexual dysfunction best addressed by VAs.

Aesthetic Penile Augmentation Procedures: A Comprehensive and Current Perspective

PURPOSE OF REVIEW

Some men experience small penis syndrome (SPS), a body dysmorphic disorder in which a patient believes their penis to be small even when it is clinically average. As cosmetic surgery becomes more widely accepted, management of SPS may present a challenge for urologists. We aim to provide an updated review of aesthetic penile augmentation procedures.

RECENT FINDINGS

Augmentation procedures range from invasive to noninvasive. Surgical solutions include grafts and flaps, suspensory ligament release, and suprapubic lipectomy. Minimally invasive solutions include injections of fillers (hyaluronic acid, polylactic acid, and polymethyl methacrylate). Noninvasive solutions include external devices such as vacuum pumps and traction devices. In the current climate, aesthetic penile augmentation is becoming a desirable option for many patients but remains clinically controversial. Our review summarizes recent and relevant studies and demonstrates the need for further research and consensus on penile augmentation procedures.

Men's Experiences and Psychological Outcomes of Nonsurgical Medical Penile Girth Augmentation: A Preliminary Prospective Study

BACKGROUND

The popularity of penile augmentation procedures is increasing, but investigation into men's experiences with these procedures and their impact on psychological well-being is lacking.

OBJECTIVES

The aim of this study was to investigate men's experiences with nonsurgical medical penile girth augmentation and assess, based on valid psychological measures, the impacts these procedures have on psychological well-being.

METHODS

Men seeking to undergo a girth augmentation (n = 19) completed an online questionnaire prior to their procedure and 6 months later that contained standardized measures assessing impacts of the procedure, penile size self-discrepancy, body dysmorphic disorder, psychological distress, self-esteem, and body image-related quality of life. Girth size was also measured preprocedure and 6 months postprocedure for a subsample of men.

RESULTS

Almost half of the men reported positive impacts of "increased self-confidence" and "increased sexual pleasure" after their procedure. Despite an average girth increase of 3.29 cm, the men still perceived that their penile girth and length was less than what they should be or less than the ideal size after their augmentation procedure. However, this perceived discrepancy was significantly smaller than before their procedures. Prior to the procedure, the men who met diagnostic criteria for body dysmorphic disorder according to self-reported questionnaire (11%, n = 2/19) and clinical interview (7%, n = 1/15) lost this diagnosis at 6 months. There were no changes in psychological distress, self-esteem, or body image-related quality of life from pre- to postprocedure.

CONCLUSIONS

Men report positive impacts on their lives after penile girth augmentation, but impacts on broader psychological well-being are mixed.

The relationship between obstructive sleep apnoea and erectile dysfunction: An underdiagnosed link? A prospective cross-sectional study

This cross‐sectional study aimed to investigate the prevalence and clinical characteristics of erectile dysfunction in patients with obstructive sleep apnoea. We enrolled 133 male patients with suspected obstructive sleep apnoea. Ear, nose and throat evaluation, laboratory tests, body mass index, Epworth sleepiness scale, 5‐international index of erectile function, overnight ambulatory polygraphy and drug‐induced sleep endoscopy patterns were assessed. Eighty patients reported obstructive sleep apnoea. 60% (n = 48) reported erectile dysfunction. Statistically significant correlations were found between 5‐International Index of Erectile Function and age, hypertension, diabetes, Epworth sleepiness scale, apnoea‐hypopnea index score, O₂ saturation‐nadir, and oxygen desaturation index. Age, diabetes and O₂ saturation‐nadir were independent predictors of erectile function. Epworth sleepiness scale, apnoea‐hypopnea index score, O₂ saturation‐nadir, oxygen desaturation index and albumin were higher compared to patients without erectile dysfunction. No statistically significant differences were reported for drug‐induced sleep endoscopy patterns and erectile dysfunction. Patients with obstructive sleep apnoea were at significant risk of having erectile dysfunction. Males with obstructive sleep apnoea should be investigated for erectile dysfunction.

Psychological Factors Related to Impotence as a Sexual Dysfunction in Young Men: A Literature Scan for Noteworthy Research Frameworks

Despite the increasing interest in clinical practice in sexual dysfunction (SD) and the related relevance of psychological outcomes for young people, this area has been neglected in scientific scenarios. This study aims to draw on recent scientific findings and propose future research perspectives on the risk factors, diagnostic issues, and therapies that address SD for the under-40 age category, with particular attention paid to various psychological aspects. A literature search was conducted on studies published between March 2011 and March 2021. Anxiety, depression, and relational conflicts can both cause and affect sexual dysfunction. Psychological interventions have also proved to be important to organic causes; however, no review has found either sex education programs or multidisciplinary therapies. A multidisciplinary approach involving medical doctors and psychologists (trained in psychosexology) would improve not only the recognition of disorders through organic and psychogenic symptoms, but also treatment effectiveness.

Use of Cosmetic Facial Injectables After Facial Aesthetic Surgery

BACKGROUND

Over the last two decades, both invasive and minimally-invasive aesthetic procedures have proliferated. Aesthetic surgeons often recommend injectable treatments after cosmetic facial surgery for multiple reasons. Yet, literature is lacking on how cosmetic surgery affects post-operative facial injectable use.

OBJECTIVES

The authors aim to identify predictors of facial injectable use after cosmetic facial surgery.

METHODS

All adult patients operated on by a single surgeon between 2013 and 2021 were retrospectively reviewed. Patients who had any of the following cosmetic facial surgeries were included: rhytidectomy, blepharoplasty, rhinoplasty, or genioplasty. Patient demographics, clinical history, intraoperative factors, and use of cosmetic facial injectables (neurotoxin, facial fillers, deoxycholic acid, poly-L-lactic acid) were recorded.

RESULTS

A total of 227 patients who underwent facial cosmetic surgery were reviewed, of which 158 were included. 89 patients had rhytidectomy (56.3%), 112 had blepharoplasty (70.9%), 28 had rhinoplasty (17.7%), and 7 had genioplasty (4.4%). 44.3% patients received injectables after their surgery (n=73), compared to only 17.7% before surgery (n=28) (p<0.001). The most common post-operative injectables were neurotoxins (48.5%) and facial fillers (46.0%), followed by deoxycholic acid (2.7%) and poly-L-lactic acid (2.7%). Multivariate regression revealed factors positively correlated with future injectable use were index blepharoplasty or rhinoplasty, and history of pre-operative neurotoxin injection (p<0.05).

CONCLUSIONS

Cosmetic facial injectables are an important consideration in achieving and maintaining optimal facial aesthetics. Their use, especially neurotoxins and facial fillers, increases among patients post-operatively. These results highlight the contribution of injectable procedures in the context of multidimensional care for augmenting facial aesthetics.

History and future perspectives of male aesthetic genital surgery

Since ancient times, men have tried to change the size and shape of their genitals. Bites from insects or poisonous snakes and weights were among the first methods used for this purpose. In the first half of the 1900s, the scientific push regarding male genital aesthetic surgery began. Scrotoplasty, penile suspensory ligament release, injection of hyaluronic acid as filler, use of several types of grafts, lipofilling, and liposuction are techniques currently used. The Penuma® implant has recently been described with promising results. We are living in the era of tailored surgery and regenerative medicine. Shortly the surgeons will have to know several surgical techniques and adapt them to the patient. New fillers with ideal characteristics, innovative prosthetic devices, and stem cells will probably be the protagonists of future aesthetic surgery. The main effort of the scientific community should be directed towards the design of new randomized controlled trials to increase the evidence on the efficacy and safety of the topic, with the ultimate aim of allowing clear recommendations from scientific societies.

Penile length augmentation surgical and non-surgical approaches for aesthetical purposes

The aim of this review is to describe reported techniques and to provide available scientific data on the success of penis length procedures for cosmetic purposes. Penis lengthening methods remain a controversial issue. Penis size is a matter of great interest among men who are affected by 'small penis anxiety'' or just believe themselves to have a small penis, even though the dimensions of the organ fall within the normal range. We performed a narrative review of the literature based on a comprehensive search in the MEDLINE database for original articles published until March 2021, referring to lengthening approaches exclusively for aesthetical reasons. Abstracts, opinion papers and case series ≤10 patients were not considered. We included the results of 14 papers in the review that gathered the experience obtained in a total of 1661 patients. Four of the studies referred to non-surgical procedures for penile length augmentation (PLA) and the remaining 10 analyzed the results of invasive (surgical) procedures. Both invasive and non-invasive techniques achieve similar improvements in penis length. These procedures vary in complexity and require specialized training and experience. However, the low scientific quality of the analyzed papers makes it difficult to establish recommendations to choose one technique over any other. However, it seems reasonable that, if possible, non-invasive techniques should be proposed as a first-line treatment. Before deciding the procedure, we must carry out a correct psychological evaluation of our patients, discuss with them the technique of choice, and adjust their expectations.

Genital Self-Image and Aesthetic Genital Surgeries: Novel Perspectives Across the Cisgender and Transgender Spectrum

Genital-focused body image concerns or negative genital self-image are a common experience across the gender spectrum, including among cisgender and transgender populations. Such concerns can result in lower psychological and sexual well-being. In this article, it is proposed that the development of genital self-image concerns may be partly explained by the theoretical framework of cisgenderism. This theory proposes that there are only 2 genders-men and women-and these are dictated solely by the appearance of the genitals. Any deviation from these 2 categories can result in discrimination, which particularly impacts transgender individuals. An increasing number of cisgender and transgender people are seeking out aesthetic genital procedures to alleviate genital self-image concerns (and gender dysphoria in transgender populations). The growing body of research suggests that cisgender and transgender men and women are relatively satisfied with the results of their genital procedures. However, this research is limited by a lack of standardized and validated patient-reported measures to evaluate surgical outcomes. Furthermore, despite negative genital self-image being a key motivator for surgery, it is often not included as an outcome measure. In this article, recommendations are proposed for conducting higher-quality evaluation studies of aesthetic genital procedures in cisgender and transgender populations. Moreover, future research and clinical directions are suggested to assist transgender men and women who choose not to undergo genital gender-confirming surgery. The vast majority of transgender individuals do not have this surgery and so are in great need of support in managing their gender dysphoria and negative genital self-image.

Penile Girth Injection Complications: A Case Report

Introduction

Penile enhancement procedures are becoming more common in men looking to achieve a more desirable penile aesthetic. We describe a case of post-procedural dermatitis after receiving penile girth enhancement injections in an adult male and discuss management of penile girth injection side effects.

Materials and Methods

We review and present our case alongside a discussion of girth injection complications.

Results

Patient's exam and symptoms improved after treatment.

Conclusion

Post-procedural complications after penile girth injections seem to be under-reported and unfortunately can result in severe deformity and dysfunction of the penis.

Penile girth enhancement procedures for aesthetic purposes

The present study aimed to describe and critically discuss the current evidence regarding the penile girth enhancement procedures for aesthetic purposes. We designed a narrative review of the literature. A comprehensive search in the MEDLINE database was performed. Original articles in English-language, published until March 2021, were selected. A total of 29 studies were included (3 reporting non-invasive approaches, 11 injection therapies, and 15 surgical procedures). The vast majority of articles (26, 89.7%) were not randomized controlled trials, with overall low quality and limited level of evidence. Only 1 (33.3%) paper regarding non-invasive approaches reported a minimal (+0.03 cm) but a significant increase of penile girth (p = 0.034). A low rate (11.2-14.4%) of mild, temporary adverse events and poor-to-moderate patient satisfaction were found. Eight (72.7%) articles concerning injection therapies showed a significant increase in penile girth (p < 0.05). A low rate of mild complications, generally at the injection site, and a high patient satisfaction rate (75-100%) were highlighted. Nine (60%) papers on surgical treatments found a significant increase in penile girth (p < 0.05), while the other 6 (40%) studies reported a generic improvement in penile circumference. Skin necrosis or ulcers, wound infections, or need for reoperation were reported in 8 (53.3%) studies. A high patient satisfaction rate (60-100%) was reported. Our review highlighted the overall positive results of injection procedures, the poor outcomes associated with non-invasive techniques, and the good efficacy and satisfaction with a non-negligible risk of complications in patients undergoing surgical treatments. However, the adverse events are probably largely under-reported and these procedures should still be considered under investigation due to the limited evidence available and the lack of guidelines.

Efficacy and Safety of Penile Girth Enhancement Using Hyaluronic Acid Filler and the Clinical Impact on Ejaculation: A Multi-Center, Patient/Evaluator-Blinded, Randomized Active-Controlled Trial

Purpose

We aimed to evaluate the efficacy and safety of penile girth enhancement (PGE) using hyaluronic acid (HA) filler with different physical properties from previous studies. Additionally, we evaluated the clinical impact on ejaculation after PGE.

Materials and Methods

This was a prospective, patient/evaluator-blinded, randomized, active-controlled, multicenter trial. Patients recruited between December 2017 and March 2018 were randomly assigned to the HA filler or control group (polylactic acid [PLA] filler). Penile girth, satisfaction level, Premature Ejaculation Profile (PEP), and self-estimated intravaginal ejaculation latency time (IELT) were assessed at baseline and at 24 weeks post-injection.

Results

Sixty-four subjects (32 in each group) completed the trial. The mean increase in girth was 22.74±12.60 mm and 20.23±8.73 mm in the HA and control groups, respectively. Satisfaction level regarding penile appearance and sexual life significantly increased in both groups. There was no statistically significant difference between the groups in terms of increase in penile girth or change in satisfaction level. Both groups showed significant improvements in PEP index scores. Self-estimated IELT also significantly increased in the HA group (from 5.36±3.51 to 7.86±4.73 minutes, p=0.0001) and control group (from 5.23±3.55 to 6.43±4.22 minutes, p=0.021). No serious adverse events (AEs) were reported.

Conclusions

PGE with HA and PLA fillers resulted in significant enhancement of girth without serious AEs with no significant differences. Furthermore, PGE using filler improved clinical symptoms related to ejaculation.
