It has been shown previously that experimental left varicocele in the rat, results in a bilateral decrease in intratesticular testosterone. In the present work, pituitary responsiveness to GnRH as a...
Induction of varicocele was attempted by partial ligation of the left renal vein in 10 male dogs. The effects on sperm count, sperm motility, and sperm morphology, as well as on hemodynamics, were a...
Doppler sonography is considered a reliable method for detecting reflux due to venous valvular incompetence, which occurs in varicocele. It is, however, a matter of debate whether the characteristic...
Unilateral varicocele has been associated with diminished male fertility in humans and with bilateral physiologic and histologic changes in the testis of humans and laboratory animals. In particul...
The present study investigated the effect of a surgically induced varicocele on the dynamics of testicular blood flow. The surface vasculature of the normal and the varicocele-affected testis was ex...
To evaluate whether correction of varicocele improves fertility, pregnancy rates were compared in 115 varicocele patients consulting for infertility and having oligozoospermia, asthenospermia, or te...
This study reports on the stagnation of blood within the microcirculatory vessels of the testes of patients with varicocele. Both fine structural and quantitative studies were carried out on testi...

Operative treatment of varicocele by anatomically high ligation of the internal spermatic vein carries a 5% surgical failure rate, resulting in recurrence. Detection of the cause of the recurrence...
Varicocele is associated with an oxidative stress condition. We have measured the antioxidant defenses of varicocele patients both at the local (seminal plasma) and systemic (blood plasma) levels. T...
Testicular microvascular blood flow is known to exhibit vasomotion, or pulsatile flow. In the present study we have used laser-Doppler flowmetry to study microvascular blood flow in the rat testis a...
