Some physiological and ethical problems make it difficult to obtain semen samples from adolescents with varicocele (VC) and to directly evaluate their fertility. Therefore we can only rely on indirect methods to assess the influence of VC on the future fertility of the adolescent patients. Most of the VC adolescents may have normal semen parameters in the adulthood. Thus whether and when to intervene in adolescent VC remain a controversy in andrology. Physical examination is the most common method for screening adolescent VC and ultrasonography is very effective for its diagnosis and evaluation. Other important diagnostic indicators include the widely accepted testicular atrophy index, recently proposed peak retrograde venous flow, total testis volume, and scrotal temperature. Based on the latest literature, this review offers some proposals for the evaluation and intervention of adolescent VC.

<p><b>OBJECTIVE</b>To investigate the correlation of vasectomy with the risk of prostate cancer in Chinese men.</p><p><b>METHODS</b>We systematically searched the databases CNKI, VIP, Wanfang, PubMed, Embase, and Cochrane Library for the literature relating the relationship between vasectomy and the risk of prostate cancer in Chinese males up to December 2014. According to the inclusion and exclusion criteria, two investigators independently selected the eligible publications, evaluated their quality, and extracted relevant information, followed by a meta-analysis with the software STATA 12.0.</p><p><b>RESULTS</b>Nine studies were included in the analysis involving 1 202 cases of prostate cancer and 4,496 controls. Random-effect model analysis revealed no statistically significant correlation between vasectomy and the risk of prostate cancer (OR = 1.05; 95% CI 0.62-1.79), with an obvious heterogeneity (P < 0.001, I2 = 85.7%). No significant publication bias was found among the included studies (Egger, P = 0.824; Begg, P = 0.348).</p><p><b>CONCLUSION</b>The results of our meta-analysis do not support the association of vasectomy with the increased risk of prostate cancer in Chinese population.</p>
