Characterization of microRNA in the follicular fluid of patients undergoing assisted reproductive technology.

Female fertility plays a decisive role in the reproduction of mammals, with related issues that include oocyte or embryo quality, establishment of pregnancy, and the physiology of the tissues that contribute to reproduction and metabolic disorders associated with reproductive failure. Although reproductive failure may be attributed to various factors in different species, female infertility is largely controlled by a number of molecular signals that can be regulated in a cycle- and tissue-dependent manner.

Peyronie's disease: a "triple oxygenant therapy".

Objectives: To evaluate the effects of upregulators of nitric oxide in one patient with Peyronie’s disease, after non significant improvement following intracavernosal verapamil.

Methods: A 20-years-old Caucasian male presented with penile induration in flaccid state, persistent during erection and associated with mild pain at third middle of penis. After treatment with intracavernosal verapamil for 4 months with relief of penile discomfort, followed by counseling on the use of penile extender for at least 6 hours per day, he was prescribed pentoxifylline associated with tadalafil plus levo-arginine, propionil-carnitine and Vitamin B3.

Asymmetric dimethylarginine (ADMA), symmetric dimethylarginine (SDMA) and L-arginine in patients with arteriogenic and non-arteriogenic erectile dysfunction.

The plasma concentration of asymmetrical dimethylarginine (ADMA), an inhibitor of nitric oxide synthase, has been linked to endothelial dysfunction. We investigated the relation between ADMA, symmetric dimethylarginine (SDMA) and L-arginine concentrations and erectile dysfunction. We compared plasma levels of ADMA, SDMA and L-arginine in 61 men in good health with erectile dysfunction of arteriogenic and non-arteriogenic origin.

Antegrade subinguinal sclerotization with temporary clamping of the spermatic cord: a new surgical technique for varicocele.

Objectives: The purpose of our study was to evaluate the duration, effectiveness, and complications associated with a new operating technique for varicocele, using a subinguinal surgical approach and antegrade sclerotization of the spermatic veins.

Methods: A total of 756 varicocele patients who came under our care for infertility underwent surgical treatment with our technique. The diagnosis was based on clinical examination and confirmed by color-Doppler ultrasound of the spermatic cord.

Evaluation of microalbuminuria in patients with erectile dysfunction.

Introduction: The recent sophisticated diagnostic procedures aimed at identifying the exact cause of erectile dysfunction (ED) are often complicated in clinical application, invasive, or highly expensive. Microalbuminuria, a test easy to perform and of low cost, is a marker of extensive endothelial dysfunction, and it has been suggested to be linked to ED.

Aim: The aim of this study was to investigate the eventual role of microalbuminuria in differentiating patients with arteriogenic and non arteriogenic ED.
