Implantation of erectile prosthesis is complicated
The final step in the multidisciplinary approach of gender reassignment therapy in female-to-male transsexuals consists of the construction of a neophallus to allow the patient to void while standing and to have sexual experience after he is accustomed to his new voiding abilities.
The main limiting factor is that there is no good substitute for the unique erectile tissue of the penis. The largest retrospective study by Hoebeke et al. evaluates the outcome in 129 female-to-male transsexuals after implantation of a hydraulic erectile prosthesis.
The article is the largest retrospective study of female-to-male transsexuals with implantation of inflatable prosthesis into neophallus.
Use of 185 implants in 129 neopenises clearly reflects that we are far from a perfect solution that enables the sexual lives of transgender patients. Different techniques have been used to obtain rigidity in the neophallus, but often they resulted in complications and failure. For all types of prostheses, there is a higher rate of infection than in studies with men; mechanical failure is also higher. The article by Hoebeke et al tries to provide explanations for these phenomena.
Despite these high complication rates, implantation of a hydraulic erectile prosthesis remains the best option for achieving the possibility of voiding while standing as well as sexual intercourse in female-to-male transsexuals after phalloplasty. The choice of device cannot be decided based on the data presented in this study; however, trends seem to reflect that two-piece devices are better than three-piece devices.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Mapping the interaction of a single atom with a single photon may inform design of quantum devices
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
