Al-Beltagi M, Saeed NK, Bediwy AS, Shaikh MA, Elbeltagi R. Microphallus early management in infancy saves adulthood sensual life: A comprehensive review. World J Clin Pediatr 2024; 13:89224. [PMID: 38947989 PMCID: PMC11212752 DOI: 10.5409/wjcp.v13.i2.89224] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Revised: 01/30/2024] [Accepted: 03/20/2024] [Indexed: 06/07/2024] Open
Abstract
Microphallus/Micropenis is a rare condition with significant physical and psychological implications for affected individuals. This article comprehensively reviews micropenis, its etiology, epidemiology, and various treatment options. We conducted a thorough literature review to collect relevant information on micropenis and microphallus, as well as related disorders. Our primary databases were PubMed, Medline, and Google Scholar. We searched for articles published in English between 2000 and 2023. Our analysis included 67 review articles, 56 research studies, 11 case reports, one guideline, and one editorial. Our search terms included "microphallus", "micropenis", "congenital hypogonadotropic hypogonadism", "androgen insensitivity syndrome", "pediatric management of micropenis", "testosterone therapy", and "psychosocial implications of micropenis". We focused on diagnosing micropenis and related conditions, including hormonal assessments, medical and surgical treatment options, psychosocial and psychological well-being, sexual development of adolescents, and sociocultural influences on men's perceptions of penile size. Additionally, we explored parenting and family dynamics in cases of micropenis and disorders of sex development, implications of hormonal treatment in neonates, and studies related to penile augmentation procedures and their effectiveness. The article highlights the importance of early diagnosis and intervention in addressing the physical and psychological well-being of individuals with micropenis. Surgical procedures, such as penile lengthening and girth enhancement, and non-surgical approaches like hormonal therapy are explored. The significance of psychological support, education, and lifestyle modifications is emphasized. Early management and comprehensive care are crucial for individuals with micropenis, from infancy to adolescence and beyond. A multidisciplinary approach involving urologists, endocrinologists, and mental health professionals is recommended. Regular assessment of treatment effectiveness and the need for updated guidelines are essential to provide the best possible care. Healthcare professionals should prioritize early diagnosis, and neonatologists should measure stretched penile length in neonates. A collaborative effort is needed among professionals, parents, and affected individuals to create a supportive environment that recognizes worth beyond physical differences. Continuous research and evidence-based updates are crucial for improving care standards.

Abstract
INTRODUCTION Division of the suspensory ligament of the penis has emerged as a popular surgical approach for penile lengthening, but accurate preoperative predictions of lengthening outcomes remain elusive. This study aimed to identify readily measurable anatomical parameters associated with post-ligamentolysis penile length gain, facilitating more reliable preoperative estimations. METHODS An experimental cross-sectional study was performed on 16 adult cadavers. Data collected before dissection included: age at death, ethnicity, height, length of the penis before dissection and width of the suspensory ligament of penis. Following the complete dissection of the suspensory ligament of penis, the depth of the pubic symphysis and the penile length after the procedure were measured. The absolute and relative length differences pre- and post-ligamentolysis were calculated. Correlation coefficients were used to study relations between these variables. RESULTS Penile length increased uniformly after complete division of the suspensory ligament (average gain: 26.38 mm, SD = 14.83 mm; range 4-60 mm). Pearson correlation revealed a significant negative correlation between pre-ligamentolysis penile length and post-ligamentolysis increase (r = - 0.601; p = 0.014), suggesting greater gains in individuals with shorter pre-ligamentolysis lengths. Age, ligament width, and pubic arch depth showed no significant correlations. Ethnicity did not impact post-ligamentolysis length increase (t = - 0.135; p = 0.894). CONCLUSIONS This study highlights the potential to predict penile length gain post-ligamentolysis through measurable anatomical parameters. The ability to anticipate the outcome of this procedure could empower surgeons to provide informed counseling, potentially elevating patient satisfaction. An experimental cross-sectional study was performed to investigate the outcomes of penile lengthening surgery Penile lengthening was achieved in all subjects via complete dissection of the suspensory ligament of the penis Penile length increase may be predicted preoperatively using easily measurable anatomical parameters NO LEVEL ASSIGNED: This journal requires that authors assign a level of evidence to each submission to which Evidence-Based Medicine rankings are applicable.

Gendered genital modifications in critical anthropology: from discourses on FGM/C to new technologies in the sex/gender system. Int J Impot Res 2023; 35:6-15. [PMID: 35246630 PMCID: PMC9935393 DOI: 10.1038/s41443-022-00542-y] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2021] [Revised: 01/31/2022] [Accepted: 02/04/2022] [Indexed: 11/08/2022]
Abstract
Since the late 19th century, genital modifications (female and male) have been an important research subject in anthropology. According to a comparative and constructivist perspective, they were first interpreted as rites of passage, then as rites of institutions. In a complex dialogue with feminist movements, 20th-century scholars recognised that the cultural meanings of these modifications are multiple and changing in time and space. Conversely, according to WHO, since the 1950s, Female Genital Mutilation or Cutting (FGM/C) has been considered a form of Violence Against Women and Girls (VAWG). Interpreted as VAWG, FGM/C has progressively been isolated from its complementary male rite, selected for special condemnation, and banned. An order of discourse has been built by WHO and other international organisations. This article provides a genealogic deconstruction of the order of discourse lexicon, highlighting dislocations between anthropology and the human rights agenda. Today, genital modifications encompass FGM/C, male circumcision, clitoral reconstruction after FGM/C, gender reassignment surgery, and intersex and 'cosmetic' genital surgery. I propose to call these procedures Gendered Genital Modifications (GGMo). GGMo implicates public health, well-being, potential harm, sexuality, moral and social norms, gender empowerment, gender violence, and prohibitive and permissive policies and laws. The selective production of knowledge on FGM/C has reinforced the social and political polarisation between practices labelled as barbaric and others considered modern, accessible, and empowering. I suggest an anthropological interpretation for the socio-cultural meanings of health, sexuality, purity and beauty. I propose future interdisciplinary studies of how consent, bodily integrity and personal autonomy bear on concepts of agency and subjectivity in the sex/gender system.

Abstract
Penile enlargement surgery is the second most desired cosmetic procedure in men worldwide. The mainstay of penile lengthening procedures is a partial release of the penile suspensory ligament system. Concerns regarding erect penis stability after this procedure have been raised by the surgical community. This study describes the anatomical features of the penile suspensory ligament system and explores the stability mechanisms of the penis. Methods This study is subdivided in two parts: an anatomical analysis and a clinical analysis. The anatomical part consists of a dissection of eight male cadavers to describe the anatomy and test the stability after sectioning successively the suspensory ligaments. The clinical part consists of an analysis of 30 patients with micropenis operated on for penile lengthening by a penile suspensory ligament release and lipofilling. Results The suspensory apparatus consists of four distinct ligamentous structures: fundiform, suspensory, dense vertical, and arcuate ligaments. These different structures are lax superficially but become firm and tense posteriorly. The section of the fundiform and suspensory ligaments did not destabilize the penis. Conclusion Penile lengthening by way of cautious suspensory ligament release can be performed without erection instability.

Long term results from a series of over 200 patients. Arch Ital Urol Androl 2022; 94:339-344.

Abstract
Introduction: We report our long experience in the surgical treatment of patients requesting penile lengthening by suspensory ligament release and placement of a custom-made soft silicone pubo-cavernous spacer. The aim was to show that with this surgical technique the results obtained are maintained over time. It is crucial to achieve postoperative satisfaction of these patients who show fragility and self-esteem problems. Methods: From 1999 to 2020, we treated 245 patients with congenital or acquired penile brevity. We carefully analysed the preoperative and postoperative (at 6, 12, 24 and 48 months) penile size of the patients to evaluate whether this technique could allow the long-term maintenance of aesthetic results. We also assessed preoperative erectile function and we focused on the psychological aspects to avoid surgery in patients with dysmorphophobia. This original technique involves the section of the suspensory ligament and the implantation of a silicone spacer between the pubic symphysis and the corpora cavernosa. This spacer is conformed to the patient anatomy and maintains the relationship between the anatomical structures unchanged over time. Sexual self-esteem and patient satisfaction were assessed with the APPSSI questionnaire. Results: The mean increase in penile length was about 2.5 cm in flaccid state and 1.9 cm in stretched state. There were no injuries of the neurovascular bundle or urethra, and no erectile dysfunction was noted. These results persisted at 6, 12, 24 and 48 months without significant differences. Over 80% of patients stated that they were completely satisfied with the results obtained. This satisfaction remained stable along follow up. Conclusion: The section of the suspensory ligament and the implant of the soft silicone spacer provide real penis elongation with satisfactory results that persist over time. This technique avoids the frequent complication of short-term shortening due to the scar adhesions of the edges of the dissected ligament. The high aesthetic satisfaction of patients is stable at controls at 6, 12, 24 and 48 months.

Abstract
In the newborn, penile length is determined by a number of androgen dependent and independent factors. The current literature suggests that there are interracial differences in stretched penile length in the newborn and although congenital micropenis should be defined as a stretched penile length of less than 2.5 SDS of the mean for the corresponding population and gestation, a pragmatic approach would be to evaluate all boys with a stretched penile length below 2 cm, as congenital micropenis can be a marker for a wide range of endocrine conditions. However, it remains unclear as to whether the state of micropenis, itself, is associated with any long-term consequences. There is a lack of systematic studies comparing the impact of different therapeutic options on long-term outcomes, in terms of genital appearance, quality of life, and sexual satisfaction. To date, research has been hampered by a small sample size and inclusion of a wide range of heterogeneous diagnoses; for these reasons, condition-specific outcomes have been difficult to compare between studies. Lastly, there is a need for a greater collaborative effort in collecting standardized data so that all real-world or experimental interventions performed at an early age can be studied systematically into adulthood.

Abstract
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.

Abstract
INTRODUCTION There are limited options for cosmetic penile enhancement and the correction of structural penile deformities. AIM We present the Augmenta, an innovative, technologically advanced subcutaneous elastomer-silicone cosmetic penile implant (CPI), as evaluated by objective structural changes in a cadaveric model. METHODS Five fresh male cadaver pelves were utilized in this preclinical setting. Placement of a subcutaneous elastomer-silicone CPI was performed via a penoscrotal approach. Penile circumference was measured at the base and distal shaft before and after implant placement. Penile length was measured from the pubic bone to the tip of the glans penis before and after implantation of Augmenta. MAIN OUTCOME MEASURE Objective outcomes included changes in penile circumference and shaft length in both the flaccid and erect state, both before and after CPI placement. RESULTS In 5 cadaver models, implantation of the Augmenta CPI increased flaccid penile shaft base circumference from an average of 8.7 cm to 12.0 cm after implantation (39.1% increase, P < .001). Flaccid distal circumference increased from 7.3 cm to 10.3 cm (41.8% increase, P = .020). During the erect state, penile base circumference increased from an average of 12.5 cm to 13.7 cm (6.3% increase, P = .273), while distal erect circumference changed from an average of 11.3 cm to 12.4 cm (9.7% increase, P = .298). Nonstretched flaccid shaft length increased from an average of 12.1 cm to 14 cm (15.2% increase, P = .073). CLINICAL IMPLICATIONS The Augmenta CPI could serve as alternative option for men seeking cosmetic penile enhancement. STRENGTHS AND LIMITATIONS Limitations include a small number of cadavers which do not completely reproduce living physiologic function and the use of a single technical approach. However, a consistent and standardized surgical approach reduces operator-dependent outcomes. Another strength is the use of fresh human cadavers that most closely represent live models. CONCLUSION In a cadaveric model, the Augmenta CPI demonstrates enhancements in penile girth in both the flaccid and erect state. The unique honeycomb technology, the embedded polyester mesh, and the antimicrobial hydrophilic coating of the Augmenta CPI may provide an advantage to currently available CPIs. Clinical trials will be needed to demonstrate both the safety and feasibility. Clavell-Hernández J, Tatem AJ, Lipshultz LI, et al.

Abstract
Background With the increasing prevalence of overweight and obesity, adult-acquired buried penis is more common in recent years. Many surgical techniques have been reported. However, none is the gold standard. Objective To evaluate the safety and efficacy of combining suprapubic liposuction and modified Devine's technique for penile lengthening in adult patients with buried penis due to obesity. Methods From September 2015 to June 2018, 26 consecutive suitable patients (mean age: 33 ± 5.7 years, mean body mass index: 29 ± 5.4 kg/m2) with a buried penis received suprapubic liposuction and modified Devine's technique for penis release in our medical centre. A retrospective study was conducted. Their penile length from tip to the skin (flaccid) was measured pre- and post-operatively. The amount of liposuction was also recorded accordingly. Results The mean length of the follow-up on the 26 patients is 18 ± 7.1 months (range 3-33 months). The average amount of liposuction is 450 ± 90.2 mL. The average penile length measured preoperatively, post-operatively (on table), and 3 months after the operation is 2.9 ± 1.3, 7.4 ± 2.1, and 5.3 ± 1.8 cm, respectively. The post-operative penile length had significantly increased by 4.5 ± 1.6 cm (on table) and 2.4 ± 0.7 cm (3 months post-operation) with a P value <.05. No patient had difficulties in sexual intercourse or urination post-operatively. None of the patients were dissatisfied with their surgical outcomes. Conclusions The combination of suprapubic liposuction and modified Devine's technique is a safe and effective method for releasing the buried penis of adults with satisfying outcomes.

Abstract
BACKGROUND Myths, misconceptions, and taboos about sexual anatomy and physiology are common and can affect sexual health and maintain harmful practices and beliefs. AIM To construct a female and a preliminary male 3-dimensional (3D) pelvic model on the basis of in vivo imaging, which could be studied in sex education and clinical practice. METHODS We retrospectively studied the images of 200 female pelvic magnetic resonance examinations and reviewed the literature to choose the optimum magnetic resonance imaging (MRI) protocol for the study of the clitoris and surrounding organs. We also conducted a cross-sectional study of 30 women who were undergoing a pelvic MRI. 15 women had undergone female genital mutilation/cutting involving the clitoris and 15 had not. The best-quality MRI images of 3 uncut and 1 cut clitoris, together with the principal surrounding pelvic organs, were selected to generate 3D reconstructions using dedicated software. The same software was used to reconstruct the anatomy of the penis and the principal surrounding pelvic organs, based on contrast-enhanced computer tomography images. Images of both models were exported in .stl format and cleaned to obtain single manifold objects in free, open source software. Each organ model was sliced and 3D printed. A preliminary feedback was collected from 13 potential users working in urology, gynaecology, sexual medicine, physiotherapy, and education. OUTCOMES The main outcomes of this study are a kit of 3D pelvic models, 2-dimensional figures of female and male sexual anatomy, and files for 3D printing. RESULTS We present a kit containing 3D models and 2-dimensional figures of female and male sexual anatomy, based on in vivo imaging and, feedbacks and suggestions received from potential users. CLINICAL TRANSLATION Our kit can be used in anatomy and sex education among and by health professionals, teachers, sex educators, students, and the general population. STRENGTHS & LIMITATIONS The strengths are that the models were based on in vivo imaging, can be dismantled/reassembled, and show analogous anatomic structures of the clitoris and the penis. The female models represent diversity, including women with female genital mutilation/cutting. The limitations are that the male model is preliminary and can be improved if based on an MRI; that imaging-based anatomic representations can differ from anatomic dissections; and that the models represent the sexual organs at rest or during an unknown state of arousal only. CONCLUSION Our kit can be studied in anatomy, biology, and sex education, as well as in clinical practice. Abdulcadir J, Dewaele R, Firmenich N, et al.

Abstract
Purpose To evaluate the efficacy and safety of penile elongation featuring simple scrotal septum detachment from the penile base to compensate for the loss of penile length during penile plication in patients with Peyronie's disease compared with conventional penile plication. Materials and Methods We conducted a retrospective analysis of 38 patients (24–75 years of age) with Peyronie's disease who underwent penile plication with or without our novel technique from January 2009 to May 2018. Penile elongation was achieved by release and detachment of the scrotal septum from the penile base to the level of the scrotal fat tissue. The objective outcome of change in stretched penile length (SPL) and the subjective outcome of patient perception of postoperative penile length were compared between groups. Any postoperative complications were recorded. Results Of the 38 patients, 16 underwent penile plication with scrotal septum detachment (elongation group) and 22 underwent penile plication only (conventional group). The postoperative mean SPL was increased in the elongation group and decreased in the conventional group (1.2±1.3 cm vs. −0.5±0.3 cm, p<0.001). Fourteen of 16 patients (87.5%) in the elongation group reported perceived penile lengthening after surgery, whereas 17/22 patients (77.3%) in the conventional group complained of penile shortening. We encountered no procedure-related complications such as hematoma, infection, or necrosis in either group. Conclusions Simple detachment of the scrotal septum from the penile base afforded both objective and subjective penile elongation without any severe complications compared with conventional penile plication.

Abstract
INTRODUCTION Although an infrequent cause of small penile size in adult men, acquired penile shortening represents a particular reconstructive challenge due to preexisting penile anatomic deformities. AIM With numerous techniques being performed, the purpose of our study is to assess available literature on length enhancement procedures used for acquired penile shortening deformities. METHODS A systematic review was performed using the guidelines outlined in the Preferred Reporting Items for Systematic reviews and Meta-analyses. Medline/PubMed, Scopus, and Cochrane Databases were used to identify papers on augmentation Phalloplasty in non-transgender males with acquired penile shortening from 1990 to 2018. MAIN OUTCOME MEASURE Outcomes, complications, and patient-reported satisfaction were analyzed. RESULTS 12 articles, involving 931 patients and 8 primary procedures, met our inclusion criteria. The majority of articles had level of evidence of 4 (83%) and Newcastle Ottawa Scale score of 6 (92%, moderate risk of bias). All studies reported mean penile length gain; however, inconsistent methodology was used when measuring penile dimensions. Mean length gain ranged from 0.6 to 6.4 cm. Overall, the mean complication rate for all techniques ranged from 0% to 50%. Post-operative satisfaction was reported in 10 (83%) studies, 7 of which used a validated scale. Patients were generally satisfied, with reported satisfaction rates ranging from 77% to 100%. CLINICAL IMPLICATIONS While numerous procedures have been described, the significant limitations in the available data preclude identifying a single superior procedure. STRENGTHS & LIMITATIONS The significant heterogeneity in the reported literature is a limitation of this study and highlights the need for standardized reporting. However, this study is the first to analyze augmentation phalloplasty literature in the setting of acquired penile shortening. CONCLUSION Augmentation phalloplasty techniques for acquired penile shortening are evolving and are continuously being modified; best-practice guidelines are crucial to achieve safe and satisfactory outcomes in this population.

Abstract
Steroid 5α-reductase type 2 deficiency (5αRD2) is a congenital disorder of sex development caused by impairment of conversion from testosterone (T) to 5α-dihydrotestosterone (DHT). DHT deficiency leads to various degrees of undervirilized external genitalia including micropenis, primarily correlated with mutations of the SRD5A2 gene that encodes 5α-reductase type 2. Four Japanese boys with isolated micropenis were diagnosed as 5αRD2 by elevated ratios of serum T/DHT, and decreased ratios of urinary 5α/5β-reduced steroid metabolites. Genetic analyses for SRD5A2 identified that the four patients shared a hypomorphic mutation R227Q that has a residual activity related to the mild-form of 5αRD2. For prepubertal micropenis, DHT was transdermally applied to the four patients at the ages of 4-11 year, increasing a median of stretched penile lengths (SPLs) from 2.6 cm (-2.5 SD) to 4.4 cm (-0.2 SD). Nevertheless, the post-pubertal penile growth was apparently retarded, despite normal levels of T secreted from well-developed testes. The second course of DHT treatment underwent at ages of 12-18 year, but unable to normalize SPLs at a range of 6.0 to 7.0 cm (-3.4 to -2.4 SD). The prostate volumes of two patients were variable at 8.1 and 21 cm3, and a sperm cell count of one patient was normal as young adult. DHT treatment contributes to development of the penis and prostate, which are favorable for the potential fertility of 5αRD2 adults. Meanwhile, the retarded penile growth and a risk of prostate overgrowth may complicate the post-pubertal management with DHT for 5αRD2 males.

Abstract
Humanacellular dermal matrix (HADM) is widely used in the field of burn wound repair and tissue engineering plastic surgery. HADM is manufactored by physical and chemical decellular process to remove the antigenic components that might cause immune rejection in dermis.The extracellular matrix of three-dimensional cell scaffold structure with collagen fibers had been used for wound repair and tissue regeneration, while HADM characterized with low absorption rate after implantation and strong ability to induce angiogenesis in host tissue. Studies reported that after the HADM was implanted into the patient, the host cells, such as fibroblasts and myofibroblasts, as well as lymphocytes, macrophages, granulocytes and mast cells, rapidly infiltrated the graft. The connective tissue and neovascularization were then formed within the HADM three-dimensional cell scaffold, the lymphatic system also appears after vascular reconstruction. Traditional urethral reconstruction using autologous skin flaps has some defects, such as complexity of the technology, risk of necrosis of the skin flaps after transplantation, and failure to achieve functional repair of the urethral epithelium. It has been reported that using HADM to reconstruct the urethra in patients with urethral stricture, hypospadias and bladder-vaginal fistula, showed promising results. Others have reported the experience of using HADM to repair and reconstruct congenital classic bladder exstrophy. HADM has also been used for tissue repair in patients with penile skin defect caused by Fonier's gangrene and hidradenitis suppurativa, and implanted under Bucks' fascia to enlarge the penis. The report of HADM implantation for treating premature ejaculation also deserves attention. Researchers found that HADM implantation can form a tissue barrier between the skin and corpus cavernosum, which can effectively reduce penile sensitivity and treat premature ejaculation. The safety and effectiveness of HADM implantation in the treatment of premature ejaculation need to be further standardized by data from multi-center, large-sample clinical studies. In summary, HADM is the extracellular matrix and three-dimensional cell scaffold of human dermis. As a new type of tissue repair material, new blood vessels are formed actively after implantation, which shows good histocompatibility. HADM has shown increasingly broad application prospects in treatment of genitourinary diseases including penis, urethra and bladder diseases. HADM has also been used in the treatment of premature ejaculation in recent clinical studies, and its long-term safety and efficacy need to be further investigated.

Abstract
The present paper addresses the psychological impact of body modifications (e.g. tattoos, body piercing and esthetic genital plastic surgery) on the sexual health of individuals and refers to past and present research insights. Body modifications are understood as invasive interventions on the human body, especially interventions on the human skin which result in (semi-)permanent changes. Tattoos and body piercing (in particular genital piercing) positively affect the sexual satisfaction and the sexual appeal of men and women but there is a controversial association with high risk sexual behavior. Moreover, this article focuses on esthetic genital plastic surgery based on the increasing interest and insights of the impact on female genital self-perception and sexual behavior.
