BACKGROUND: From 2014-2016, our clinical practice progressively incorporated several male infertility and andrology procedures performed under local anesthesia, including circumcision, hydrocelectomy, malleable penile prostheses, orchiectomy, penile plication, spermatocelectomy, testicular prostheses, varicocelectomy, vasectomy reversal (VR), and testicular and microepididymal sperm aspiration (TESE/MESA). Given the observed outcomes and potential financial and logistical benefits of this approach for surgeons and patients, we sought to describe our initial experience...

REVIEW
Robert M Coward, Jesse N Mills
A variety of surgical options exists for sperm retrieval in the setting of obstructive azoospermia (OA). With appropriate preparation, the majority of these techniques can safely be performed in the office with local anesthesia and with or without monitored anesthesia care (MAC). The available techniques include percutaneous options such as percutaneous epididymal sperm aspiration (PESA) and testicular sperm aspiration (TESA), as well as open techniques that include testicular sperm extraction (TESE) and microsurgical epididymal sperm aspiration (MESA)...

BACKGROUND: The sertoli cells in the testis create unique and safe environment to protect seminiferous tubules from auto antigens and invading pathogens. These cells produce the survival factor of the blood-testis barrier and produce special materials such as androgen binding proteins and contribute to the coordinated action of spermatogenesis. Given that the sertoli cells play an essential role in spermatogenesis and the lack of these cells leads to the disruption of spermatogenesis, it is necessary to investigate the behavior and performance of these cells...

A bacterial strain designated Tese-5T was isolated from a water convolvulus field in Taiwan and characterized using the polyphasic taxonomic approach. Strain Tese-5T was an aerobic, Gram-stain-negative, non-motile, rod-shaped bacterium and formed bright yellow coloured colonies. Strain Tese-5T grew at 15-35 °C (optimum, 30 °C), with 0-1.0 % NaCl (optimum, 0-0.5 %) and at pH 5.5-7 (optimum, pH 6). The major fatty acids (>10 %) of strain Tese-5T were C18 : 1ω7c, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and C16 : 0...

INTRODUCTION: Recent evidences demonstrated that male factor alone is responsible for about 30% cases of infertility. Human follicle-stimulating hormone (hFSH) has been introduced to increase sperm concentration, spermatogonial population, or both natural or assisted pregnancy rates (PRs) in oligozoospermic subjects with normal concentrations of gonadotropins. METHODS: Fifty infertile men affected by idiopathic azoospermia were enrolled in this study, after undergoing medical history, physical and clinical examination, baseline semen parameters and hormonal plasma concentrations...

BACKGROUND: The most common chromosomal abnormality due to non-obstructive azoospermia (NOA) is Klinefelter syndrome (KS) which occurs in 1-1.72 out of 500-1000 male infants. The probability of retrieving sperm as the outcome could be asymmetrically different between patients with and without KS, therefore logistic regression analysis is not a well-qualified test for this type of data. This study has been designed to evaluate skewed regression model analysis for data collected from microsurgical testicular sperm extraction (micro-TESE) among azoospermic patients with and without non-mosaic KS syndrome...

Klinefelter Syndrome (KS) is the most common chromosomal disorder in men leading to non-obstructive azoospermia. Spermatozoa can be found by TESE in about 50% of adults with KS despite severe testicular degeneration. We evaluated AR variations and polymorphism length in 135 non-mosaic KS patients, aimed to find possible correlation with clinical features, sex hormones and sperm retrieval. Among 135 KS patients we found AR variations in eight subjects (5.9%). All variations but one caused a single amino acid substitution...

This study aimed to dissociate the intravascular and extravascular contributions to spin-echo (SE) and gradient-echo (GE) blood oxygenation level-dependent (BOLD) signals at 7 T, using dynamic diffusion-weighted MRS. We simultaneously acquired SE and GE data using a point-resolved spectroscopy sequence with diffusion weightings of 0, 600, and 1200 s/mm(2) . The BOLD signals were quantified by fitting the free induction decays starting from the SE center to a mono-exponential decay function. Without diffusion weighting, BOLD signals measured with SE and GE increased by 1...

BACKGROUND: Most patients with testicular cancer are infertile; thus, the preservation of the sperm after surgery is an important factor to consider. We report two cases of bilateral testicular cancer in patients who underwent bilateral higher orchiectomy and simultaneous testicular sperm extraction. CASE PRESENTATION: Two Asian-Japanese men were referred to our hospital with bilateral testicular tumors. Both of the patients were preoperatively diagnosed with azoospermia and requested testicular sperm extraction at the time of higher orchiectomy...
