INTRODUCTION: Penile cancer is a rare urological malignancy with an age-standardised incidence of 0.8 per 100,000 person-years [1]. Given this low incidence it has been suggested that centralised care may improve patient outcomes in relation to phallus sparing surgery and nodal assessment [2]. We aim to assess the outcomes after 5-years of national centralisation of penile cancer care. METHODS: A retrospective analysis of prospectively collected data was performed...

Four yeast strains, representing a novel anamorphic species, were isolated in Thailand. The two strains (ST-3660T and ST-3647) were obtained from two different estuarine water samples in a mangrove forest. Strain DMKU-FW1-37 was derived from a grease sample, and another strain (TSU57) was isolated from a fruiting body of Phallus sp. Pairwise sequence analysis showed that the four strains had identical or differed by only one nucleotide substitution in the D1/D2 domains of the large subunit (LSU) rRNA gene, and differed by one to three nucleotide substitutions in the internal transcribed spacer (ITS) regions...

Identifying the molecular origins by which new morphological structures evolve is one of the long standing problems in evolutionary biology. To date, vanishingly few examples provide a compelling account of how new morphologies were initially formed, thereby limiting our understanding of how diverse forms of life derived their complex features. Here, we provide evidence that the large projections on the Drosophila eugracilis phallus that are implicated in sexual conflict have evolved through co-option of the trichome genetic network...

BACKGROUND: Aphallia is a rare congenital anomaly often associated with other urogenital anomalies. The management of aphallia cases for both the immediate and long-term treatment of patients with aphallia pose a major dilemma. Patients are at risk for psychosocial and psychosexual challenges throughout life. METHODS: A systematic review was conducted on aphallia cases. We searched online databases until March 2023 for relevant articles and performed according to the PRISMA-P guidelines...

Composition and content of volatiles, the important factors in flavor formation of edible fungi, are affected by growth process. GC-MS was performed and a total of 102 volatiles were identified in Phallus impudicus . Almost all identified volatile compounds showed an obvious upward trend at four growth period, and reached the maximum at fourth stage (PIII), of which the transition from first stage (ZP) to second stage (PI) achieved a breakthrough for 88 volatile compounds from scratch. The PCA and HCA results showed that the four stages were completely separated and appeared different, among which third stage (PII) and PIII might be the two dramatic change nodes in aroma quality...

Coronaviruses (CoV) are among the major viruses that cause common cold in humans. Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is a high-risk human pathogen that derived from bat coronaviruses, although several other animals serve as CoV hosts, contributing to human infection. As the human activity area expanded, viruses previously prevalent only in animals mutated and became threats to humans as well, leading to worldwide epidemics. Therefore, controlling CoV infections in animals is essential to prevent CoV-related human infections...

INTRODUCTION: Severe or proximal hypospadias is associated with inadequate local tissue and small phallus size. Pre-operative androgens have been used to increase phallus size, but there are very few studies on its role in proximal hypospadias. AIM AND OBJECTIVE: This study aimed to assess the effects of pre-operative intramuscular (IM) testosterone on proximal penile hypospadias in terms of penile morphology and tissue characteristics of penile skin. MATERIALS AND METHODS: This prospective observational study was conducted on 27 patients of proximal hypospadias over a period from June 2017 to July 2018...

A novel endemic pest of clove tree, Cryptophasa warouwi sp. nov., has been discovered on Sangihe Island. This new species can be distinguished from its closest relative species, C. watungi Sutrisno & Suwito, 2015 which is found in North Sulawesi, by its dark brown straw-coloured wings in both males and females. The most distinctive diagnostic characters of this new species are observed in its genitalia structure: a bent-downward uncus with a strongly sclerotized finger-shaped apex, a bent phallus gradually widened towards coecum, and a double, membranous corpus bursae branching off at mid-ductus corpus bursae of female genitalia...

Precocious puberty, characterised by the early appearance of secondary sexual characteristics, poses challenges in diagnosis and management. Here, we describe a case of precocious puberty diagnosed in a boy in middle childhood, who presented with progressive phallus enlargement, pubic hair development and increased aggressive behaviour. Hormonal evaluation confirmed the diagnosis of congenital adrenal hyperplasia (CAH), complicated by gonadotropin-dependent precocious puberty. The case highlights the importance of assessment of testicular volume in a patient presenting with precocious puberty...

Introduction: During early development in most male mammals the testes move from a position near the kidneys through the abdomen to eventually reside in the scrotum. The transabdominal phase of this migration is driven by insulin-like peptide 3 (INSL3) which stimulates growth of the gubernaculum, a key ligament connecting the testes with the abdominal wall. While all marsupials, except the marsupial mole ( Notoryctes typhlops ), have a scrotum and fully descended testes, it is unclear if INSL3 drives this process in marsupials especially given that marsupials have a different mechanism of scrotum determination and position relative to the phallus compared to eutherian mammals...

OBJECTIVE: To describe phalloplasty subunits and determine the preferred crowdsourced aesthetics. Aesthetic ideals are often used to guide reconstruction, and there has been an increase in the number of gender-affirming surgeries and reconstructive phalloplasties performed1,2 . However, there is a paucity of literature describing ideal phalloplasty aesthetics. METHODS: Phallus aesthetic subunits were defined, and a split testing-based survey was used. Subjects were solicited via Craigslist, Amazon Mechanical Turk, and Reddit and distributed amongst healthcare co-workers...

BACKGROUND: Anal sex remains the greatest HIV transmission risk for men who have sex with men and carries substantial population attributable risk among women. Despite a growing array of HIV pre-exposure prophylaxis (PrEP) options, rectal microbicides remain desirable as on demand, non-systemic PrEP. Rectal microbicide product development for PrEP requires understanding the spatiotemporal distribution of HIV infectious elements in the rectosigmoid to optimize formulation development. SETTING: Outpatient setting with healthy research participants...

The antiviral activity of aqueous and ethanol extracts from the fruiting bodies of gasteroid Basidiomy-cetes of Western Siberia: Lycoperdon pyriforme, Lycoperdon perlatum, and Phallus impudicus, as well as an aqueous extract from cultivated mycelium of P. impudicus and total polysaccharides from it, on MDCK cell culture against influenza A virus, was studied. Aqueous and ethanol extracts from the fruiting bodies of all studied gasteroid fungi showed antiviral activity against human influenza virus A/Aichi/2/68 (H3N2) and bird A/chicken/Kurgan/05/2005 virus (H5N1)...

BACKGROUND: Partial phalloplasty flap loss presents an evolving challenge, largely due to the complex demands required for both aesthetics and function. We describe our novel experience using the superficial circumflex iliac perforator (SCIP) propeller flap for neophallus salvage when skin grafting alone provides insufficient soft tissue bulk or coverage. METHODS: We retrospectively reviewed patients who underwent SCIP propeller flap reconstruction after phalloplasty partial flap loss...

Primary vaginal calculi are uncommon in children. Urethral duplication in females is seen to occur in association with complex congenital malformations. We report the case of perianal persistent urogenital sinus with a hypertrophied clitoris with phallic urethra, scrotum-like pouch, uterus didelphys with obstructed hemivagina, and giant colpolithiasis in 46XX female. A 16-year-old presented with pain abdomen and cyclic passage of blood clots per rectum. She had a tender lump in left iliac region, a phallus like protrusion and a ruggous sac below it...

The nominate subgenus Lyponia Waterhouse, 1878 from China is reviewed, with two new species described and named L. (s. str.) ruficeps sp. n. (China, Yunnan) and L. (s. str.) zayuana sp. n. (China, Xizang). A distribution map and a key to all species of Lyponia s. str. are provided. Moreover, the phenotypic relationships among the species of Lyponia s. str. are investigated based on phallus shapes using geometric morphometric and phylogenetic morphometric analyses. The topologies demonstrate that the species are divided into two clades...

INTRODUCTION AND IMPORTANCE: Circumcision is the most common surgical procedure done in boys. Its complication varies from minor to severe. In most of African countries circumcision is often performed by traditional circumcisers. The management of penile glans amputation depends on the duration before presentation with auto-transplantation being the favorable management in acute phase of presentation. The amputation of the glans is a serious complication of circumcision because it can derange the urinary and sexual functions of a patient and may lead into psychological instability and low self-esteem...

BACKGROUND: Musculocutaneous latissimus dorsi (MLD) phalloplasty is a gender-affirming surgical option for transmen which permits penile prosthesis, glansplasty, and urethral extension at later stages. This surgery allows for a neophallus of adequate length and girth, and minimal donor site morbidity, but is technically complex. OBJECTIVE: This video demonstrates a step-by-step technique and tips to optimize outcomes and simplify the operation for the MLD phalloplasty...

Morphological polymorphism offers rich opportunities for studying the eco-evolutionary mechanisms that drive the adaptations of local populations to heterogeneous and changing environments. In this study, I explore the association between pollution load, abundance of large fruit-tree tortrix Archips podana and its within-species diversity (expressed in the presence of apical and/or lateral prongs on the phallus in male genitalia) across 26 study sites located 0.5 to 31 km from the industrial city of Lipetsk in central Russia...
