Evaluation of sexual function and psychological attitudes in adult women with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase Deficiency (21-HD)

Cozzolino A. , Simeoli C. , Vitale P. , Vignozzi L. , Iacuaniello D. , Grasso L. , Maggi M. , Colao A. , Pivonello R.

Women with CAH have decreased fertility and sexual activity because of psychological aspects and genital status. The aim of this study was to evaluate sexual function and psychological attitudes in 18 women with CAH due to 21-HD (12 with non-classical, four with salt-wasting and two with simple virilizing CAH; 20–48 yrs) under standard treatment, and 18 age-matched healthy women. Sexual function was evaluated by a validated Female Sexual Function Index (FSFI) questionnair...

Testosterone restores diabetes-induced erectile dysfunction and sildenafil responsiveness in two distinct animal models of chemical diabetes

Filippi S , Morelli A , Vignozzi L , Zhang XH , Luconi M , Donati S , Forti G , Maggi M

Objectives: Hypogonadism is often associated with diabetes mellitus and both conditions represent major risk factors for erectile dysfunction (ED). The aim of this study was to evaluate the effect of diabetes-induced hypogonadism on ED using two distinct animal models: alloxan-rabbits and streptozotocin (STZ)-rats.Methods: A subgroup of diabetic animals was Testosterone (T) replaced. After 8 weeks from induction of diabetes, erectile function was evaluat...

Phosphodiesterase type 5 expression in human and rat lower urinary tract tissues and the effect of tadalafil on prostate gland oxygenation in spontaneously hypertensive rats

Morelli A. , Sarchielli E. , Comeglio P. , Filippi S. , Mancina R. , Gacci M. , Vignozzi L. , Carini M. , Vannelli G. , Maggi M.

Introduction: In humans, prostate PDE5 expression was prominently localized in the endothelial and smooth muscle cells of the vascular bed, suggesting a possible action of PDE5 inhibitors on prostate blood flow.Aim: To investigate PDE5 expression in human and rat lower urinary tract (LUT) tissues and determine the effects of PDE5 inhibition with tadalafil on prostatic blood perfusion.Main outcome measures: Human vesicular-deferenti...

Beneficial effects of testosterone supplementation on prostatitis-like alterations in an animal model of metabolic syndrome

Morelli A , Filippi S , Vignozzi L , Comeglio P , Sarchielli E , Maneschi E , Cellai I , Vannelli G B , Maggi M

Introduction: Several studies suggested a direct relationship between metabolic syndrome (MetS) and increased risk of benign prostatic hyperplasia (BPH). An inflammatory component, mainly mediated by IL-8, has been proposed as the primary link between MetS and BPH pathogenesis. MetS, is often associated with testosterone (T) deficiency and an imbalance between the androgen and estrogen ratio characterizes BPH patients.Methods: We investigated the effects...

BXL-628, a vitamin D analog, decreases RhoA/ROK signalling in rat and human bladder

Morelli A , Filippi S , Mancina R , Vignozzi L , Vannelli GB , Ambrosini S , Crescioli C , Donati S , Adorini L , Maggi M

BXL-628 is a non-hypercalcemic calcitriol analog successfully tested in a phase IIa trial for benign prostate hyperplasia therapy. Because part of low urinary tract symptoms (LUTS) are generated by overactive bladder (OAB) and bladder expresses the calcitriol receptor (VDR), we investigated the BXL-628 effects on bladder contractility and RhoA/ROK signalling activated in OAB, by in vivo (2-weeks; 30 mcg/Kg, Sprague-Dawley, SD, and spontaneously hypertensive rats, SHR) a...

Testosterone supplementation improves adipose tissue function in an animal model of metabolic syndrome

Morelli A , Maneschi E , Vignozzi L , Filippi S , Marchetta M , Mazzanti B , Calcagno A , Comeglio P , Cellai I , Vannelli G B , Maggi M

Introduction: Adipose tissue dysfunction is associated to metabolic syndrome (MetS), a clustering of cardio-metaboilic risk factors, including hypogonadism. We recently demonstrated that T supplementation was able to ameliorate the metabolic profile and reduce visceral fat accumulation in high-fat diet (HFD)-induced rabbit model of MetS.Methods: We evaluated the differentiation capacity of preadipocytes (rPAD) obtained from visceral fat of the following ...

Effect of chronic tadalafil administration on penile hypoxia induced by cavernous neurotomy in the rat

Vignozzi L , Morelli A , Filippi S , Donati S , Luconi M , Zhang XH , Ambrosini S , Vannelli GB , Mirone V , Forti G , Maggi M

Objectives: Radical prostatectomy is an effective therapy for clinically localized prostate cancer. A significant number of men develops post-prostatectomy erectile dysfunction (PPED), due to surgery-related nervous damage. PPED is relatively refractory to PDE5i therapy. In a rat model of bilateral cavernous neurotomy we evaluated whether chronic tadalafil treatment (CTT) could ameliorate anatomical and functional damage to corpora cavernosa (CC).Methods...

Testosterone protects from metabolic syndrome-associated prostate inflammation: an experimental study in rabbit

Vignozzi L. , Morelli A. , Sarchielli E. , Comeglio P. , Filippi S. , Cellai I. , Maneschi E. , Serni S. , Gacci M. , Carini M. , Piccinni M. , Saad F. , Adorini L. , Vannelli G. , Maggi M.

Metabolic syndrome (MetS) and benign prostatic hyperplasia (BPH)/lower urinary tract symptoms (LUTS) are often associated. One of their common denominators is hypogonadism. However, testosterone supplementation is limited by concerns for potential prostatic side effects. The objective was to determine whether MetS-associated prostate alterations are prevented by testosterone supplementation. We used a previously described animal model of MetS, obtained by feeding male rabbits ...
