PURPOSE In the United States more men are diagnosed with cancer than women. We quantified the differential mortality rates of nonsex specific cancers between the sexes and compared cancer stage distributions. MATERIALS AND METHODS In this descriptive epidemiological study we obtained the incidence of new cancer cases, cancer deaths and stage distributions(More)
INTRODUCTION Controversy exists regarding testosterone replacement therapy (TRT) in men following radical prostatectomy (RP). Many clinicians are hesitant to offer patients TRT after an RP, out of concern that the increased androgen levels may promote tumor progression or recurrence from residual tumor. Recently, several small studies have demonstrated the(More)
PURPOSE Although microdissection testicular sperm extraction has become first line therapy for sperm retrieval in men with nonobstructive azoospermia, there are challenges to the procedure, including difficulty differentiating between seminiferous tubules with normal and abnormal spermatogenesis. Multiphoton microscopy illuminates tissue with a near(More)
Spermatogenesis is an extraordinary complex process. The differentiation of spermatogonia into spermatozoa requires the participation of several cell types, hormones, paracrine factors, genes and epigenetic regulators. Recent researches in animals and humans have furthered our understanding of the male gamete differentiation, and led to clinical tools for(More)
PURPOSE A rat varicocele model using partial occlusion of the left renal vein was described previously. Reproducibility in creating this model has met with varied success. Alternate routes of testicular venous drainage may negate the effect of partial renal vein occlusion on varicocele creation. We hypothesized that varicocele induction would be more(More)
Testicular varicocele, which is defined as the dilation of the veins draining the testicle, has long been associated with a detrimental effect on testicular function. Despite a lack of high-quality, prospective data, recent evidence has shed light on potential links between varicocele and male infertility and serum testosterone levels. Similarly, varicocele(More)
BACKGROUND The utilization of penile prosthesis (PP) insertion in the general population for medically refractory erectile dysfunction (ED) has not been well-characterized. This study assessed the national temporal trends in the surgical management of ED utilizing PP. MATERIALS AND METHODS An analysis of the 5% Medicare Public Use Files from 2001 to 2010(More)
