Ayhan Verit
It was more recently announced by archeological society that cave art about human being dated back to 8,000 years ago had been discovered at southern Asia Minor. The primitive human figures involved the phallus pointing the ground almost the same size with legs. The cave artists represented their masterpiece without any exaggeration with the exception of extraordinary phallus. The erected penis is regarded as the symbol of giver of life and linked with the creator of the Universe in the initial period of art...

REVIEW
Mayer N Fishman
Squamous penile cancer may be localized to the phallus, metastatic to regional lymph nodes, or metastatic to distant lymph nodes or other organs. In the clinical situation of regional lymph node metastasis, a multimodality approach can have a big impact on outcomes. In particular, use of systemic chemotherapy as a neoadjuvant treatment is discussed, with several examples illustrating instances of regression and of resistance, and contrasting with adjuvant timing for use of chemotherapy. Radiation with coordinated combined chemotherapy is another complementary, locally directed approach that can be considered for men with squamous penile cancer with regional lymph node spread...

BACKGROUND: In our practice we have encountered 4 female-to-male transgender patients seeking neophallus revision surgery for girth precluding penetrative vaginal or anal intercourse. Despite this, there is little evidence available to guide transitioning patients in neophallus sizing. In this work we examined the dimensions of bestselling realistic dildos, presuming that the most popular dimensions would reflect population preferences for penetrative toys and phalluses. AIM: To determine a maximal upper limit for girth compatible with penetrative intercourse based on measurements of bestselling realistic dildos and published erect penile dimensions...

Among squamate reptiles, dozens of lineages have independently evolved complete or partial limb reduction. This remarkable convergence of limbless and limb-reduced phenotypes provides multiple natural replicates of different ages to explore the evolution and development of the vertebrate limb and the gene regulatory network that controls its formation. The most successful and best known of the limb-reduced squamates are snakes, which evolved a limb-reduced body form more than 100 million years ago. Recent studies have revealed the unexpected finding that many ancient limb enhancers are conserved in the genomes of snakes...

The Helicoverpa/Heliothis complex can cause serious damage to agricultural crops. Phenotypic similarity makes it difficult to discriminate between closely related Helicoverpa species. Currently, morphology of the male genitalia complemented with molecular techniques constitutes the best approach for species identification. In this work, a broad microscopic examination of adult Helicoverpa zea (Boddie) males (n = 200) captured in central Argentina was carried out in order to provide a detailed description of the valvae and the phallus...

BACKGROUND: Phalloplasty with urethral lengthening is the procedure of choice for female-to-male transgender patients who desire an aesthetic phallus and standing micturition, but is associated with complications, including urethral stricture and fistula formation. Horizontal urethra construction can be accomplished with labia minora flaps covered with additional vascularized layers of vestibular tissue when vaginectomy is performed concomitantly with phalloplasty. However, vaginectomy is not a requisite step in phalloplasty, and some individuals may choose to retain their vagina...

PURPOSE: Phalloplasty is a critical step in female-to-male (transmale) gender confirming genital surgery. We examined outcomes between transmales who underwent phalloplasty with vaginectomy and full-length urethroplasty using the anterolateral thigh pedicled flap or the radial forearm free flap. MATERIALS AND METHODS: We performed a single center, retrospective study of patients who underwent phalloplasty with vaginectomy and full-length urethroplasty using an anterolateral thigh pedicled flap or a radial forearm free flap from April 2013 to July 2016...

PURPOSE OF REVIEW: Genitourinary vascularized allotransplantation (GUVCA) is gaining interest as a treatment option for patients with functional and aesthetic urogenital tissue loss. Only three cases have been done worldwide and research on the implementation and feasibility of this procedure is in an elementary state. RECENT FINDINGS: The psychosocial impact and ethical considerations with GUVCA are remote, particularly because of the intimate and personal nature of genital tissue...

Deficiency of the 5-α-reductase enzyme has been found to affect male sexual development. We report an 18-year-old patient who was referred to an endocrinology clinic in Jizan, Saudi Arabia, in April 2014 with primary amenorrhoea, virilisation and a lack of secondary sex characteristics. As female external genitalia were present at birth, she had been raised as a female. Magnetic resonance imaging revealed no uterine or ovarian tissue in the pelvis and the presence of a scrotal sac. She was diagnosed with 5-α-reductase type 2 deficiency, a 46,XY disorder of sexual development...

There are very few reported cases of traumatic amputation of the male genitalia due to animal bite. The management involves thorough washout of the wounds, debridement, antibiotic prophylaxis, tetanus and rabies immunization followed by immediate reconstruction or primary wound closure with delayed reconstruction, when immediate reconstruction is not feasible. When immediate reconstruction is not feasible, long-term good functional and cosmetic results are still possible in the majority of cases by performing total phallic reconstruction...

Given the rising HIV incidence in men who have sex with men (MSM) despite repeatedly proven effectiveness of oral HIV pre-exposure prophylaxis, behaviorally congruent periodic dosing strategies, such as dosing microbicides as lubricants, are now in demand. Rectal microbicide gel studies largely administer gels using vaginal applicators, which have not been well received and do not mimic lubricant use. We compared rectal gel manually dosed as lubricant with applicator dosing in five healthy, HIV-negative MSM who received 10 or 3...

Species of Belostoma in the dentatum and subspinosum groups are large and closely related, and have been combined by some authors into a single group, the dentatum group, comprising 15 species. This group is recognized by the scutellum reaching the nodal line and the ventral diverticulum of the phallus with distinct dorsal caudal and ventroapical protuberances. Previously, each group included five and 10 species, respectively; members of the dentatum group ranged in length from 38.0 to 52.0 mm, whereas those of the subspinosum group ranged from 26...

Gender dysphoria is estimated to occur in approximately 25 million people worldwide, and can have severe psychosocial sequelae. Medical and surgical gender transition can substantially improve quality-of-life outcomes for individuals with gender dysphoria. Individuals seeking to undergo female-to-male (FtM) transition have various surgical options available for gender confirmation, including facial and chest masculinization, body contouring, and genital surgery. The World Professional Association for Transgender Health guidelines should be met before the patient undergoes surgery, to ensure that gender-confirming surgery is appropriate and indicated...

Rather than migrating, mallard ducks may choose to overwinter in northern cities on open-water thermal refuges, such as municipal wastewater treatment ponds, which in Edmonton, Canada, stay ≥10°C during frigid winter months. Refuging mallards spend appreciable time daily on these ponds and hydrate using secondary clarified municipal wastewater (SCEW). We aimed to determine if SCEW ingestion affected mallard health. To this end, we gavaged newly hatched mallards (domesticated Pekin strain) over their first month with SCEW, as well as water representing negative and positive controls (municipal tap water, and the primary active ingredient from birth control pills, 17α-ethinyl estradiol (EE2), respectively)...

Hypospadiology is a rapidly evolving field. Progress in the understanding of how hormonal therapy affects the growth of the phallus has allowed surgeons to optimize the tissues for surgery. But conflicting data from a number of studies and a lack of consensus on drugs, their dosing, mode of delivery and timing of use means that the creation of protocols is unlikely to happen in the near future. Nonetheless, there is a hope and the standardization of scientific reporting will make it easier to compare data at the global level...

Phallic reconstruction is an important part of management for congenital aphallia. Scrotal flap phalloplasty has been described in pediatric patients to create the appearance of a nonfunctioning phallus. We describe a modified scrotal flap technique with the addition of an acellular dermal matrix patch (AlloDerm) to provide additional girth and support to the phallus. The postoperative cosmetic outcome has been satisfactory and there is no documented complication over a 12-month follow-up. AlloDerm dermal matrix can be a safe addition to phallic reconstruction and its overall application needs to be further studied...

A 50-year-old male with past medical history of diabetes mellitus presented with extensive Fournier's Gangrene. He had a wide-spread area of involvement and the wound vacuum placement involved the entirety of the phallus. We describe a surgical technique where the penis can be diverted from the site of the wound to allow for more secure wound vacuum placement and future reconstructive options.

A new genus of Tortricinae, Zebraodes Heppner & Bae, n. gen., is described for the new species Zebraodes lucidalis Heppner & Bae, n. sp., from Vietnam (Tortricidae: Tortricinae: Archipini). The new genus is anomalous among archipines, resembling some Ceracini, but with genital features more similar to those of Archipini, notably the strongly convex phallus in the male genitalia, together with the strong uncus; however, the absence of a signum in the female genitalia is unusual for the tribe.
