BACKGROUND Present knowledge on the impact of varicoceles on testicular function is largely based on studies of subfertile and infertile men, making it difficult to extrapolate the impact of varicocele on the general population. OBJECTIVE To describe associations between varicocele and testicular function assessed by semen analysis and reproductive hormones in men from the general population....

In the past, the indications for varicocelectomy are primarily for infertility with abnormal semen parameters, testicular hypotrophy/atrophy in adolescents, and/or pain. The surgical treatment of varicocele for hypogonadism is controversial and debated. Recently, multiple reports in the literature have suggested that varicocele is associated with hypogonadism and varicocele repair can increase ...

Varicocele is the most common correctible cause of male infertility and is present in 15% to 20% of the male population. Despite its prevalence, the pathophysiology of varicocele remains under investigation. One of the largest obstacles in studying varicocele is that it is almost exclusively found in humans. This has necessitated the creation of an animal model of varicocele. The most commonly ...

BACKGROUND We designed this study to clarify how varicocele can time-dependently affect sperm morphological parameters and DNA integrity. In this study, we intend to estimate the effect of various periods of varicocele on the in vitro fertilization (IVF) rate in rats. MATERIALS AND METHODS In this experimental study, left varicocele were induced as the test group (n=18) which was further sub-...

The objective of this review was to summarize the evidence concerning the benefit of varicocele treatment to improve natural fertility in subfertile males. We also analyzed the effect of varicocele treatment on conventional semen parameters and sperm functional tests. An electronic search to collect the data was performed using the PubMed/MEDLINE databases until July 2015. Data pooled from a va...

Varicocele is often cited as the most common cause of male factor infertility. Arguments in support of this statement include reports of increased prevalence of varicocele in populations of infertile men compared with fertile or otherwise unselected men, association of varicocele with abnormal semen parameters, and improvements in semen parameters and/or pregnancy rates after varicocele repair....

Thirty-seven infertile patients with varicocele were treated with Guizhi-Fuling-Wan (7.5 g/day) for at least 3 months. Before and after the administration, semen qualities such as sperm concentration and motility were examined, and the varicocele was graded. A varicocele disappearance rate of 80% was obtained with 40 out of 50 varicocele, and improvement of sperm concentration and motility were...
