Effect of Testosterone Treatment on Clitoral Arteries' Hemodynamic Parameters.

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).
