Genital gender affirmation surgery (gGAS) for individuals assigned female at birth (AFAB) is complex and requires the staged insertion of an erectile device to permit penetrative intercourse. This final stage of gGAS is challenging, owing to the variable anatomy and lack of supportive structures within the neophallus when compared with erectile device insertion for individuals assigned male at birth. There is a paucity in the literature at present regarding erectile device insertion in trans-sex AFAB patients.

Background: Total phallic reconstruction (TPR) is a reconstructive challenge.

Objective: To report both surgical outcomes and patient-reported outcomes (PROs) of genetic male patients undergoing TPR utilising a radial artery forearm free flap (RAFFF).

Design, Setting, And Participants: A retrospective tertiary referral centre analysis of a series of genetic male patients with penile insufficiency (PI) either due to congenital micropenis, or from traumatic or surgical amputation was conducted.

Introduction: To date, several aspects of inflatable penile prosthesis (IPP) surgical procedure have been poorly studied.

Aim: The aim of this study was to review the evidence associated with IPP implantation and provide clinical recommendations on behalf of the European Society for Sexual Medicine (ESSM). Overall, 130 peer-reviewed studies and systematic reviews, which were published from 2007-2018 in the English language, were included.

Objectives: To assess the oucomes of penile prosthesis (PP) implantation after total phallic reconstruction secondary to gender dysphoria.

Patients And Methods: We conducted a retrospective single-centre analysis of 247 consecutive patients. The recruitment period was January 2001 to October 2015.

Objective: To assess the prevalence of obstructive sleep apnoea (OSA) in men presenting with erectile dysfunction (ED) at a single centre.

Patients And Methods: All men attending a specialised andrology outpatient department with a new diagnosis of ED were included in this prospective study. All patients completed three questionnaires: the International Index of Erectile Function (IIEF) and two sleep questionnaires [the Obstructive Sleep Apnoea Screening questionnaire and the Insomnia Severity Index (ISI)].

Objectives: To evaluate the efficacy and safety of collagenase clostridium histolyticum (CCH; Xiapex , Xiaflex ) in the treatment of Peyronie's disease (PD) using a new modified treatment protocol that aims at reducing the number of injections needed and reducing patient visits, thus reducing the duration and cost of treatment.

Patients And Methods: A prospective study of 53 patients with PD who had treatment with CCH at a single centre using a new modified protocol. The angle of curvature assessment after an intracavernosal injection of prostaglandin E1, the International Index of Erectile Function (IIEF) and Peyronie's Disease Questionnaire (PDQ) were completed at baseline and at week 12 (4 weeks after the last injection).

Objective: To compare the long-term results of early and delayed insertion of a penile prosthesis (PP) in men with refractory ischaemic priapism (IP).

Patients And Methods: Early insertion of a PP was carried out in 68 men with IP within a median of 7 days from the onset of priapism, while 27 had delayed insertion after a median of 5 months. The results for sexual ability, satisfaction and subjective penile shortening were assessed by questioning at follow-up visits.

Purpose: The current management of ischemic priapism that is refractory to conventional medical therapy is a form of shunt procedure that diverts blood away from the corpus cavernosum. We assessed the outcome of the T-shunt and intracavernous tunneling for the management of ischemic priapism.

Materials And Methods: During a 36-month period 45 patients presented with prolonged ischemic priapism.

Background: Ischaemic priapism (IP), which is refractory to conventional medical and surgical intervention, results in necrosis of the corpus cavernosum smooth muscle. These patients eventually develop a variable degree of corporal smooth muscle fibrosis that presents as erectile dysfunction and penile shortening.

Objectives: To evaluate the long-term outcome of patients who have undergone the immediate insertion of a penile prosthesis as a treatment for an acute episode of IP refractory to medical therapy or shunt surgery.

In this study, 185 British and 143 American undergraduates completed a battery of tests that measured attitudes toward animal testing and various individual difference variables. Attitudes toward animal testing factored into two interpretable factors: general attitudes toward animal testing, and animal welfare and conditions of testing. Overall, there was support for animal testing under the right conditions, although there was also concern for the welfare of animals and the conditions under which testing takes place.

To assess how different facets of aging anxiety contributed to the prediction of tangible and existential death anxiety, 167 Americans of various Christian denominations completed a battery of questionnaires. Multiple regression analyses, controlling for demographic variables and previously demonstrated predictors of death anxiety, revealed that the aging anxiety dimensions of physical appearance concern and fear of losses each positively predicted tangible death anxiety. In addition, the aging anxiety dimension of fear of losses predicted existential death anxiety.
