Histological and immunohistochemical outcomes after microdissection TESE in contrast with hormonal profile, testis volume and genetics in patients with azoospermia.

A limited number of individuals with non-obstructive azoospermia (NOA) may recover spermatozoa through traditional testicular sperm extraction (TESE) techniques. There is an ongoing debate over the effectiveness of microdissection TESE compared to standard TESE methods. Microdissection TESE (micro-TESE) techniques enable the identification of spermatogenesis foci in non-obstructive forms of azoospermia.

The Correlations of Clinical and Biochemical Indices of Vitamin D with Erectile Dysfunction.

Erectile dysfunction is a multifactorial disease; it has been demonstrated that endothelial dysfunction plays an essential role in the pathogenesis of this disease, and Vitamin D deficiency is considered to favor endothelial lesions. Our study, based on a group of 58 patients who have erectile dysfunction and a control group of 26 healthy subjects, tends to confirm that low levels of vitamin D could potentiate the severity of erectile dysfunction, promoting endothelial dysfunction. Statistical analysis using the Pearson's correlation criteria showed a robust and significant correlation between vitamin D levels and erectile dysfunction severity (ρ=0.
