Autor: Marcello Cocuzza, Suresh C. Sikka, Kelly S. Athayde, Ashok Agarwal

Publikováno v: International Brazilian Journal of Urology, Vol 33, Iss 5, Pp 603-621 (2007)

Oxidative stress (OS) in the reproductive tract is now a real entity and concern due to the potential harmful effects of high levels of reactive oxygen species (ROS) on sperm number, motility, quality, and function including damage to sperm nuclear D

Although varicocele size has an inverse relationship with baseline semen parameters and a direct relationship with seminal reactive oxygen species in infertile patients, to our knowledge the effect of varicocele grade in fertile men is unknown. We ev

Publikováno v: Journal of andrology. 28(4)

In spite of prompt diagnosis and either orchiectomy or preservation of the affected testis, infertility remains a significant sequel to testicular torsion. The objective of this study was to evaluate the late endocrine profile, seminal parameters, an
