RESUMEN

Men are particularly sensitive to penis size, especially those with a deformed or injured penis. This can lead to a strong desire for penis enlargement surgery. Given the ethical sensitivities of the penis, penile implants need to be developed with both efficacy and safety. In this study, a polyvinyl alcohol (PVA) patch for penile enlargement prepared via cyclic freeze‒thaw cycles and alkaline treatment. The PVA hydrogels treated with 5 M NaOH had the best mechanical properties and stability. A negative Poisson's ratio structure is incorporated into the design of the enlargement patch, which allows it to conform well to the deformation of the penis. In rabbit models, the enlarged patches can effectively enlarge the penis without degradation or fibrosis while maintaining long-term stability in vivo. This innovation not only provides a safe option for patients in need of penile enlargement but also promises to make a broader contribution to the field of dynamic tissue repair.

RESUMEN

In this study, we formally examine the association between penis size dissatisfaction and gun ownership in America. The primary hypothesis, derived from the psychosexual theory of gun ownership, asserts that men who are more dissatisfied with the size of their penises will be more likely to personally own guns. To test this hypothesis, we used data collected from the 2023 Masculinity, Sexual Health, and Politics (MSHAP) survey, a national probability sample of 1,840 men, and regression analyses to model personal gun ownership as a function of penis size dissatisfaction, experiences with penis enlargement, social desirability, masculinity, body mass, mental health, and a range of sociodemographic characteristics. We find that men who are more dissatisfied with the size of their penises are less likely to personally own guns across outcomes, including any gun ownership, military-style rifle ownership, and total number of guns owned. The inverse association between penis size dissatisfaction and gun ownership is linear; however, the association is weakest among men ages 60 and older. With these findings in mind, we failed to observe any differences in personal gun ownership between men who have and have not attempted penis enlargement. To our knowledge, this is the first study to formally examine the association between penis size and personal gun ownership in America. Our findings fail to support the psychosexual theory of gun ownership. Alternative theories are posited for the apparent inverse association between penis size dissatisfaction and personal gun ownership, including higher levels of testosterone and constructionist explanations.

RESUMEN

Introducción y objetivo: La cirugía de alargamiento y engrosamiento de pene supone un reto técnico para el cirujano, puesto que las técnicas clásicas han demostrado resultados insuficientes para los pacientes. Nuestro objetivo es presentar nuestra experiencia con una técnica reproducible que permite evitar el empleo de extensores y las complicaciones de la infiltración de grasa. Material y método: Analizamos de forma retrospectiva 750 casos de alargamiento y engrosamiento de pene primarios realizados con la técnica NEF (No Extenders No Fat) - No Extensores No Grasa), analizando la técnica quirúrgica, sus resultados y complicaciones. Esta técnica se basa en la creación de un colgajo de avance cutáneo junto con un colgajo de fascia de Scarpa y un nanofat infiltrado en las fascias profundas del pene. Resultados: La ganancia media en longitud en el grupo de pacientes estudiados fue de 4.8cm en reposo, con un espectro de 2 hasta 8.1cm. En el engrosamiento, se alcanzó un incremento medio de 1.17 cm (mínimo de 0.5 y máximo de 1.8 cm). Conclusiones: La tasa de satisfacción de pacientes, de complicaciones y retoques en nuestro grupo de estudio nos hablan de una cirugía que mejora las técnicas previas, más invasivas y con mayor tasa de complicaciones. El apoyo psicológico y la ayuda profesional preoperatoria es imperativa, y se debe ofrecer especialmente en casos de dismorfofobia. El trabajo pre y postoperatorio es esencial en estos pacientes. Conseguir pacientes con expectativas reales es la primera barrera que debemos franquear. Solo cuando el paciente haya entendido la cirugía y sus resultados, debemos avanzar hacia ella. (AU)

Background and objective: Penis lengthening and thickening surgery is a technical challenge for the surgeon, since classical techniques have shown insufficient results for patients. Our objective is to present our experience in the develop of a a reproducible technique that avoids the use of extensors and the complications of fat infiltration. Methods: Retrospectiv análisis of 750 cases of primary penis enlargement and thickening performed with the NEF (No Extenders No Fat) technique, analyzing the surgical technique, its results and complications. This technique is based on the creation of a skin advancement flap, together with a Scarpa fascia flap and a nanofat infiltrated at the deep fascia of the penis. Results: Mean gain in length in the group of patients studied was 4.8 cm at rest with a spectrum from 2 to 8.1 cm. In thickening, the measurement reached an average increase of 1.17 cm (minimum of 0.5 and a maximum of 1.8 cm). Conclusions: Rates of patient satisfaction, complications and retouching in our group tell us about a surgery that improves previous more invasive techniques with a higher rate of complications. Psychological support and professional pre-surgery help is imperative and should be offered especially in those cases of dysmorphophobia. Pre and postoperative work is essential in these patients. Getting patients with real expectations is the first barrier we must overcome. Only when the patient has understood the surgery and its results, should we move towards it. (AU)

RESUMEN

Appearance of the male genitalia is linked with self-esteem and sexual identity. Aesthetic surgery of the male genitalia serves to correct perceived deficiencies as well as physical deformities, which may cause psychological distress. Attention to patient motivation for surgery and to surgical technique is key to achieving optimal results. In this review, the authors describe aesthetic surgical techniques for treatment of penile and scrotal deficiencies. They also discuss techniques for revision in patients with previous surgery.
