Effect of microsurgical varicocelectomy on fertility outcome and treatment plans of patients with severe oligozoospermia: An original report and meta-analysis.

Varicocele ligation has been proven to restore semen parameters and improve pregnancy rates in men with clinical disease. However, its effect in men with severe oligozoospermia (SO) is less clearly elucidated. This original report and meta-analysis examined the impact of subinguinal microsurgical varicocelectomy on semen parameters and fertility outcomes of men with SO.

Serum testosterone status in men with penile corporoveno-occlusive dysfunction.

Background And Objectives: Vascular abnormalities are the most common factors in patients with erectile dysfunction (ED). There are limited number of case series investigating the etiology of corporoveno-occlusive dysfunction (CVOD). In this study, we evaluated ED patients with vascular etiologies and their serum biomarkers from a large database.

Vitamin D and Male Erectile Function: An Updated Review.

Literature support that vitamin-D is important for different systems of the human body including, but not limited to endocrine and immune systems, vasculature and endothelial function of the body. Male erectile function depends on many factors and can be perceived as a health indicator of the body. Epidemiological data have shown that vitamin-D deficiency is also associated with erectile dysfunction.

Use of testicular sperm for ICSI in oligozoospermic couples: how far should we go?

In 1992 and subsequently, several reports indicated that ICSI was a successful technique to achieve clinical pregnancy and live birth using spermatozoa with severely impaired characteristics. The initial optimism over the ability of ICSI to overcome significant sperm abnormalities was later tempered by the findings of more recent publications suggesting that some sperm deficits may not be as effectively treated with ICSI. In search for effective treatment for couples with severe male factor, a number of small retrospective and prospective studies have reported high pregnancy and live birth rates using testicular sperm for men with necrozoospermia, cryptozoospermia and oligozoospermia with or without elevated sperm DNA damage.
