The long-term use of cyproterone acetate in pedophilia: a case study.
This investigation reports the long-term use of the antiandrogen cyproterone acetate (CPA) in a pedophile, who was studied continuously over 38 months. Measures of sexual arousal, serum testosterone, and gonadotropin levels were significantly reduced by the drug as compared with placebo and no treatment; prolactin levels were significantly elevated. Some workers have observed that long-term administration of CPA (more than one year, which was then discontinued) produced enduring (in some cases apparently permanent) anti-libidinal effects; however, in the case described, within three weeks of stopping the drug, all measures had returned to pretrial levels. The importance of continuous long-term monitoring in sex offenders receiving an antiandrogen is discussed.

Hormonal contraceptives, one of the most widely used contraceptive methods, are associated with the development of thromboembolism. Purinergic mediators such as soluble agonists, ectonucleotidases, and receptors play a prominent role in regulating hemostasis. This study aimed to evaluate E-NTPDase, E-5'-NT, and E-ADA activities in lymphocytes and platelets from women using combined oral contraceptives.

Background: Low-dose sublingual estradiol gender-affirming hormone therapy (GAHT) in treatment-naive transgender women effectively suppresses testosterone and initiates breast development, comparable to oral estradiol with cyproterone acetate; however, its impact on body composition remains unstudied.
Aim: To assess early body composition changes with low-dose estradiol, compare sublingual versus oral administration efficacy, and evaluate bioelectrical impedance analysis (BIA) and dual-energy X-ray absorptiometry (DXA) agreement in transgender women undergoing GAHT.
Methods: In this 6-month prospective study, 22 treatment-naïve transgender women received either 2 mg/day sublingual estradiol (SLE) or combined oral (CO)-2 mg/day oral estradiol plus 10 mg/day cyproterone acetate.

Objective: No studies have investigated muscle strength and thickness in adolescents with polycystic ovary syndrome (PCOS). We investigated whether there were changes in quadriceps muscle thickness and strength between adolescents with PCOS and controls. Secondly, we evaluated the effects of six months of combined oral contraceptive (COC) treatment on the quadriceps muscle.

Transgender (TG) people are individuals whose gender identity and sex assigned at birth do not match. They often undergo gender-affirming hormone therapy (GAHT), a medical intervention that allows the acquisition of secondary sex characteristics more aligned with their individual gender identity, providing consistent results in the improvement of numerous socio-psychological variables. However, GAHT targets different body systems, and some side effects are recorded, although not yet fully identified and characterized.

Flow chemistry has many advantages over batch synthesis of organic small-molecules in terms of environmental compatibility, safety and synthetic efficiency when scale-up is considered. Herein, we report the 10-step chemo-biocatalytic continuous flow asymmetric synthesis of cyproterone acetate (4) in which 10 transformations are combined into a telescoped flow linear sequence from commercially available 4-androstene-3, 17-dione (11). This integrated one-flow synthesis features an engineered 3-ketosteroid-Δ-dehydrogenase (ReM2)-catalyzed Δ-dehydrogenation to form the C1, C2-double bond of A ring, a substrate-controlled Co-catalyzed Mukaiyama hydration of 9 to forge the crucial chiral C17α-OH group of D ring with excellent stereoselectivity, and a rapid flow Corey-Chaykovsky cyclopropanation of 7 to build the cyclopropyl core of A ring.
