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 non-functioning 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 post-operative 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.

We performed a successful penis allotransplantation on 11 December 2014. Sharing the lessons learned might help more patients in need to be treated this way. We divided the project into manageable segments that was each overseen by an expert. The ethical review and conduct paved the way for a publically acceptable and successful project. Screening for a psychological stable recipient is important. The most difficult part of the project was finding a donor penis. This was successfully negotiated with the family of a brain dead donor by creating a neo-phallus for the donor, thereby maintaining the dignity of the donor...

Flap failure from microvascular thrombotic occlusion is a rare but significant cause for unsuccessful reconstructive surgery. We encountered thrombosis of arteriovenous loop in a patient undergoing phallus reconstruction. Further investigations revealed underlying previously asymptomatic hypercoagulable state due to protein-S deficiency in addition to long-term exogenous testosterone administration. Role of thrombophilia testing, thrombogenic potential of testosterone and the need for therapeutic perioperative anti-coagulation in such situations are described here...

Marsupials are born with undifferentiated gonads, and their reproductive organs differentiate consecutively, not simultaneously as in eutherian mammals. Thus, in the main marsupial model, the tammar wallaby, Macropus eugenii, the testis forms cords 2 days after birth, the ovary develops cortex and medulla about 8 days after birth, the Wolffian duct enlarges from day 10, the prostate begins to form prostatic buds about 25 days after birth, and the phallus does not become sexually dimorphic until after 50 days postpartum (pp)...

BACKGROUND: Acquired or congenital absence of the penis can lead to severe physical limitations and psychological outcomes. Phallic reconstruction can restore various functional aspects of the penis and reduce psychosocial sequelae. Moreover, some female-to-male transsexuals desire creation of a phallus as part of their gender transition. Because of the complexity of phalloplasty, there is not an ideal technique for every patient. This review sets out to identify and critically appraise the current literature on phalloplasty techniques and outcomes...

An intromittent phallus is used for sperm transfer in most amniote taxa; however, there is extensive variation in external genital morphology within and among the major amniote clades. Amniote phalluses vary in number (paired, single, or rudimentary), spermatic canal morphology (closed tube or open sulcus), and mode of transition between resting and tumescent states (inflation, rotation, eversion, or muscle relaxation). In a phylogenetic context, these varying adult anatomies preclude a clear interpretation for the evolutionary history of amniote external genitalia; as such, multiple hypotheses have been presented for the origin(s) of the amniote phallus...

In brief Most injuries to the penis and scrotum in sports result from direct blows and require prompt evaluation. Bicycler's penis is a paresthesia and numbness in the perineum and phallus that resolve spontaneously. A direct blow to the scrotum usually causes a testicular contusion that responds to elevation of the scrotum and bed rest. Athletes wear athletic supporters and plastic cups for scrotal protection. Sexually transmitted diseases-nongonococcal urethritis, condyloma acuminatum, and herpes progenitalis-are common urologic problems in athletes...

In April 2014, poor fertility in a major commercial goose breeder operation in California triggered the submission of six live affected Toulouse ganders ( Anser anser ) to the California Animal Health and Food Safety Laboratory, Turlock branch (University of California-Davis). Toulouse were principally affected among all breeds, and their egg fertility dropped from 65.7% to less than 33.9% in the first 40 days of the 2014 breeding season. The flock consisted of 410 adult birds, 90 males and 320 females, between 2 and 5 yr of age...

A 6½ years Indian boy was brought by his parents, who were anxious about the excessive increase in the size of the boy's phallus, from the age of 2 years. On physical examination, the child had a penis length greater than the 97th centile for age, a sexual maturity rating of gonads at stage 2 and pubic hair at stage 3, with height in the high normal range (90-97th centile). The bone age was 12 years. Laboratory evaluation showed pubertal levels of testosterone and pubertal gonadotropin response to stimulation, confirming central precocious puberty (CPP)...

The distal part of the crocodilian phallus consists of a bulbous glans containing well-developed vascular tissues that can inflate before or during sexual activity, enlarging and elaborating the glans into a complex, though still functionally undefined, copulatory structure. An enlarged glans putatively interacts with the female cloaca and may change the shape of her reproductive tract to facilitate insemination and increase the probability of fertilization. Here, we investigated the cellular-level properties of the glans and other inflatable phallic tissues associated with the sperm-conducting sulcus spermaticus in the American alligator (Alligator mississippiensis)...
