BACKGROUND: About 75% of urothelial bladder cancers are non-muscle invasive (NMIBC), and limited to mucosa (Ta or CIS) or sub-mucosa (T1). An increase of androgen expression and androgen receptors has a positive effect on oncogenic expression. We aimed to evaluate whether 5-alpha reductase inhibitors (5-ARI) have a role in NMIBC. METHODS: We retrospectively evaluated the clinical and pathological data of 423 patients with NMIBC who underwent transurethral bladder resection. We analysed the number of resections, number of total recurrences, time of recurrences, and histopathology details.

Neural Progenitor Cells (NPCs) are multipotent cells that are able to self-renew and differentiate into neurons. The size of the initial pool of NPCs during the brain development strongly affects the number of neurons that compose cortical multi-layer during development. Gonadal hormones can influence the balance between self-renewal and differentiation processes. Herein, we investigated the role of dihydrotestosterone (DHT), the active metabolite of testosterone, in the regulation of NPC stemness and differentiation.

androgen receptor variant 7 (AR-V7) has been suggested as potential marker for treatment selection in men with metastatic castration-resistant prostate cancer (mCRPC). The aim of the present review is to critically analyze: frequency of the AR-V7 expression in mCRPC cases-impact of AR-V7 expression on abiraterone, enzalutamide, and taxane therapy.

Context: Hirsutism often occurs in women with polycystic ovary syndrome (PCOS). The efficacy of oral contraceptive pill (OCP) plus antiandrogens in the treatment of its severe expression is controversial due to the lack of randomized, double-blind, long-term studies. Objective: The primary outcome was the reduction of hirsutism in PCOS women objectively measured by videodermoscopy on the androgen-sensitive skin areas assessed by the modified Ferriman and Gallwey (mF&G) total score, after 12 months of therapy with OCP + bicalutamide (BC) vs OCP plus placebo (P).
