Current research interests 

Clinical research on erectile dysfunction and hypogonadism: 1) organic and psycho-relational correlates of male sexual dysfunction, 2) cardiovascular risk factors in men with erectile dysfunction, 3) clinical and metabolic correlates of low testosterone, 4) cardiovascular risk associated with low testosterone levels and with testosterone replacement therapy.

Ultrasound: 1) male genital tract and penile color-Doppler ultrasound evaluation in infertile and fertile subjects and in patients with sexual dysfunctions; 2) association of ultrasound features with clinical, seminal and biochemical parameters. In particular, the Unit mainly focuses on the investigation of ultrasound correlates of male infertility, sexual dysfunctions, chronic pelvic pain and on the impact of obesity and metabolic syndrome on sonographic, seminal and sexual parameters.

Female Sexual Dysfunction: organic and psycho-relational determinants of female sexual desire; sexual and psychological symptoms in patients with eating disorders (e.g. anorexia nervosa), metabolic alterations (e.g. obesity) and history of sexual trauma; effects of oral contraceptives containing androgenic progestins compared with other contraceptives on sexuality; effects of sex steroids on clitoral Doppler parameters; effect of alterations of thyroid function on female sexuality; organic and psycho-relational correlates of genito-pelvic pain/penetration disorder.

Gender Dysphoria in adulthood and adolescence: effects of CHT on hormonal and metabolic parameters, bone density, anthropometric characteristics, as well as physical well-being of GD persons (European Network for the Investigation of Gender Incongruence, ENIGI); psychobiological correlates of gender dysphoria, particularly in terms of body uneasiness and psychopathological symptoms; psychobiological effects of gender transition; transphobia and homophobia levels in general population and healthcare providers; Psychobiological correlates of gender dysphoria in adolescence.

Basic research of hypogonadism and sexual medicine: The laboratory basic research activities focused mainly on:

•             Pathophysiology of the erectile function and investigation of the urogenital tract derangements induced by metabolic syndrome (MetS), diabetes and hypertension, by means of ex-vivo and in-vitro studies in rabbit and rat animal models

•             Bladder, prostate and corpora cavernosa dysfunction in animal models, with particular focus on the effects of PDE5 inhibitors and sexual hormones on the underlying pathogenetic mechanisms

•             Effect of physical activity on penile erection and peripheral vascular districts functional alterations induced by high-fat diet in an animal model of MetS

•             Effect of the changing sex-steroid milieu on clitoris function in a rat model of ovariectomy

•             Studies on adipose tissue dysregulation and liver dysfunction associated with MetS features, including LUTS and inflammation, focusing on the role of androgen/estrogen ratio in pre-adipocytes from visceral adipose tissue in the rabbit animal model of MetS

•             Mechanisms regulating differentiation and function of gonadotropin-releasing hormone neurons in humans and MetS animal models
