The regulation of clitoral vascularization by sex steroids is still under-investigated. We aimed to explore the effects of 6 months transdermal Testosterone (T) therapy on clitoral color Doppler ultrasound (CDU) parameters in pre- and postmenopausal women with female sexual dysfunction (FSD). In order to do that, we retrospectively recruited n=81 women with FSD, divided into 4 groups according to different treatments followed as per clinical practice, for 6 months: transdermal systemic 2% T gel; local estradiol ovules; local non-hormonal moisturizers; transdermal T plus local estrogens.
Our main hypothesis is that systemic T treatment is able to positively modulate clitoral blood flow in basal conditions, specifically to increase clitoral artery Peak systolic velocity (PSV).
Strong clinical evidence supports the use of transdermal systemic testosterone (T) treatment for Hypoactive Sexual Desire Disorder (HSDD) in menopausal women. According to preclinical studies, T is necessary to maintain the functional machinery underlying clitoral arousal response. In hypogonadal men with erectile dysfunction, T replacement therapy is able to improve penile vasodilation as assessed by using color Doppler ultrasound (CDU). On the other hand, the regulation of clitoral vascularization by sex steroids is still under-investigated.
We aimed to explore the effects of 6 months T therapy on clitoral CDU parameters and sexual function in pre- and postmenopausal women with female sexual dysfunction (FSD).
Adult heterosexual women attending our clinic for sexual concerns were retrospectively recruited. A subgroup of sexually active patients with FSD (n=81) was divided into 4 different groups according to different treatments followed as per clinical practice: women with Hypoactive Sexual Desire Disorder (HSDD) treated with off-label transdermal 2% T gel once daily (300 mcg T per day, n=23); women with dyspareunia due to moderate to severe vulvovaginal atrophy (VVA), treated with local estrogens (estradiol ovules) taken daily for 2 weeks and afterwards twice a week (n=12); women with dyspareunia due to mild to moderate VVA, treated with non-hormonal moisturizers every 2-3 days (n=37); women with HSDD reporting also significant dyspareunia due to moderate to severe VVA, treated with combined therapy (transdermal T and local estrogens) (n=9). Patients underwent physical, laboratory, uterine and genital (clitoral and uterine arteries) CDU examinations, and completed the Female Sexual Function Index (FSFI). at baseline and after 6 months.
Our main hypothesis is that systemic T treatment is able to positively modulate clitoral blood flow in basal conditions, specifically to increase clitoral artery Peak systolic velocity (PSV).
