Recovery of testicular spermatozoa from non-obstructive azoospermic patients for intracytoplasmic sperm injection (ICSI) is a recent advance in the treatment of male infertility. The purpose of this study is to identify predictive factors for sperm recovery in non-obstructive azoospermic patients. A total of 178 men with non-obstructive azoospermia had(More)
Recent studies have provided evidence that Zn2+ plays a crucial role in ischemia- and seizure-induced neuronal death. However, the intracellular signaling pathways involved in Zn2+-induced cell death are largely unknown. In the present study, we investigated the roles of mitogen-activated protein kinases (MAPKs), such as c-Jun N-terminal kinase (JNK), p38(More)
BACKGROUND No studies have been published comparing the U- and H-type methods of the TVT SECUR (TVT-S) procedure. OBJECTIVE Our aim was to compare the efficacy and safety of the two types of TVT-S for female stress urinary incontinence (SUI). DESIGN, SETTING, AND PARTICIPANTS Women with urodynamic SUI were enrolled in this 12-mo multicenter randomized(More)
OBJECTIVE To assess the improvement of seminal characteristics and pregnancy rates after microsurgical varicocelectomy in men with subclinical varicocele. DESIGN Retrospective study. SETTING University infertility clinic. PATIENT(S) One hundred forty-three patients with a subclinical left-sided varicocele. INTERVENTION(S) Patients who agreed to(More)
OBJECTIVES To investigate the effect of microsurgical varicocelectomy in nonobstructive azoospermic patients. The surgical outcomes were correlated with the histopathologic patterns of testicular specimens. METHODS A total of 19 nonobstructive azoospermic men who underwent testicular biopsy and varicocelectomy were included in the study. In 15 patients,(More)
Despite growing interest in overactive bladder (OAB), urinary incontinence (UI), and lower urinary tract symptoms (LUTS), there is no epidemiologic study on the prevalence in general population of Korea. This survey was aimed at estimating the prevalence of OAB, UI, and other LUTS among Korean men and women. Population-based cross-sectional telephone survey(More)
Polymorphisms in the genes encoding enzymes in the folate metabolism pathway have been associated with male infertility and chromosome abnormalities. The aim of this study was to analyze the distribution of the methylenetetrahydrofolate reductase (MTHFR), methionine synthase (MTR), and methionine synthase reductase (MTRR) polymorphisms in fertile men and(More)
OBJECTIVE The aim of this study is to investigate the various causes of male infertility using multiple approaches. METHODS Nine-hundred-twenty infertile male patients were analyzed at their first visit with one physician between January 1 and December 31, 2009. All patients were subjected to physical examination, semen analysis and azoospermic patients(More)
Varicocele is the most common cause of male infertility and is generally correctable or at least improvable by various surgical and radiologic techniques. Therefore, it seems simple and reasonable that varicocele should be treated in infertile men with varicocele. However, the role of varicocele repair for the treatment of subfertile men has been questioned(More)
PURPOSE Urologic injuries occur frequently during surgery in the pelvic cavity. Inadequate diagnosis and treatment may lead to severe complications and side effects. This investigation examined the clinical features of urologic complications following obstetric and gynecologic surgery. MATERIALS AND METHODS We accumulated 47,318 obstetric and gynecologic(More)
