BACKGROUND: Cryptozoospermia (CO) is a situation in which spermatozoa cannot be observed in a fresh semen sample unless an extended centrifugation and microscopic search are performed. CO patients are suggested to use only intracytoplasmic sperm injection (ICSI) as infertility treatment. But still there is debate about the choice of sperm source in cryptozoospermic men candidate for ICSI. OBJECTIVES: This study was conducted to evaluate fertility outcomes in men with idiopathic cryptozoospermia who were treated using ICSI with freshly ejaculated sperm and testis sperm extraction (TESE) or percutaneous epididymal sperm aspiration (PESA)...

OBJECTIVE: To compare the clinical outcomes of intracytoplasmic sperm injection (ICSI) between spermatozoa retrieved from testicular biopsy and from ejaculate in cryptozoospermia patients. METHODS: The clinical data of 285 cryptozoospermia patients, who underwent ICSI treatment in our center during the period from March 2009 to November 2013, were retrospectively analyzed. Within them, ejaculated sperms were used in 214 cases (group 1) and testicular sperms extracted by testicular sperm aspiration (TESA) or conventional testis dissection sperm extraction (TESE) were used in 71 cases (group 2)...

BACKGROUND: The bispectral index parameter is used to guide the titration of general anesthesia; however, many studies have shown conflicting results regarding the benefits of bispectral index monitoring. The objective of this systematic review with meta-analysis is to evaluate the clinical impact of monitoring with the bispectral index parameter. METHODS: The search for evidence in scientific information sources was conducted during December 2013 to January 2015, the following primary databases: Medline/PubMed, LILACS, Cochrane, CINAHL, Ovid, SCOPUS and TESES...

In this article, we report a case of pregnancy obtained in an infertile couple diagnosed with severe male factor infertility. The couple attended for fertility examination reporting a history of 10 years of infertility. The cause of infertility was obstructive azoospermia. The treatment consists of in vitro fertilization (IVF). The ovarian stimulation of female patient was done with antagonist protocol and after ovarian puncture was obtained nine oocytes. The urologist performed testicular sperm extraction (TESE)...

BACKGROUND: Secreting interstitial cell (Leydig cell) tumors are rare. In adults, the clinical picture and steroid levels are variable. CASE PRESENTATION: This paper presents a case of left testicular tumor, showing azoospermia with normal serum level of total testosterone, collapsed FSH and LH, and high delta4 androstenedione. Histopathological investigation revealed a Leydig cell tumor. TESE allowed spermatozoa extraction and freezing. Testicular histology found hypospermatogenesis and germ-cell aplasia with interstitial fibrosis...

Background/Aims: Diastolic dysfunction is associated with cardiovascular (CV) events in end-stage renal disease (ESRD) on continuous ambulatory peritoneal dialysis (CAPD). However, conventional measurement of LA volume and E/e' using Doppler echocardiography has been limited to predict CV events in patients with ESRD on CAPD. Methods: From September 2007 to September 2008, 30 consecutive patients with exertional dyspnea in ESRD on CAPD and normal systolic function was prospectively enrolled and underwent laboratory testing, coronary angiography, and treadmill exercise stress echocardiography (TESE)...

AIM: To report the outcome of intracytoplasmic sperm injection (ICSI) cycles using fresh or cryopreserved-thawed testicular spermatozoa of men with Klinefelter syndrome (KS). METHODS: Medical records of 83 azoospermic men with KS who underwent testicular sperm extraction (TESE) were reviewed. The clinical parameters for predicting sperm retrieval and fertilization, implantation, pregnancy and live birth rates of ICSI cycles in these patients were evaluated. RESULTS: A total of 88 TESE procedures were performed with sperm retrieval rates of 39...

BACKGROUND: Embryonic stem cell (ESC) derivatives hold great promise for the construction of tissue-engineered skin equivalents (TESE). However, harvesting of ESCs destroys viable embryos and may lead to political and ethical concerns over their application. In the current study, we directed mouse parthenogenetic embryonic stem cells (pESCs) to differentiate into fibroblasts, constructed TESE, and evaluated its function in vivo. METHODS: The stemness marker expression and the pluripotent differentiation ability of pESCs were tested...

Scrapie and bovine spongiform encephalopathy (BSE) are transmissible spongiform encephalopathies (TSE's) affecting sheep and goats. Susceptibility of goats to scrapie is influenced by polymorphisms of the prion protein gene (PRNP) of the host. Five polymorphisms are associated with reduced susceptibility to TSE's. In the study presented here caprine samples from a scrapie eradication program on Cyprus were genotyped and further characterized using BioRad TeSeE rapid test, histological, immunohistochemical and biochemical methods...

BACKGROUND: Socioeconomic disadvantage is associated with an increased risk of adverse diabetes outcomes. In Switzerland, a country with theoretical universal healthcare coverage, people without health insurance face barriers in accessing to and in receiving standard quality care. The Geneva University Hospitals (HUG) have implemented policies aiming at reducing these gaps. We compared quality of diabetes care and ambulatory healthcare services utilization among insured and uninsured diabetic patients...

: Intracytoplasmic sperm injection (ICSI) is the most frequently applied method for fertilization making the process of identifying the perfect spermatozoon fundamental. Herein we offer a critical and thorough presentation on the techniques reported regarding (i) handling and preparing semen samples, (ii) identifying and 'fishing' spermatozoa, and (iii) improving key factors, such as motility for a successful ICSI practice. These approaches are suggested to make the process easier and more effective especially in atypical and challenging circumstances...

BACKGROUND: The availability of testis specific genes will be of help in choosing the most promising biomarkers for the detection of testicular sperm retrieval in patients with non-obstructive azoospermia (NOA). Testis specific chromodomain protein Y 1 (CDY1) is a histone acetyltransferase which concentrates in the round spermatid nucleus, where histone hyperacetylation occurs and causes the replacement of histones by the sperm-specific DNA packaging proteins, TNPs and PRMs. OBJECTIVE: The aim was to evaluate CDY1 gene as a marker for predicting of successful sperm retrieval in NOA patients...

The purpose of this study was to observe the clinical utility and the possible determinants in predicting sperm retrieval of salvage microdissection testicular sperm extraction (mTESE) for nonobstructive azoospermia (NOA) patients with failed conventional TESE at their first attempts. A total of 52 NOA males underwent salvage mTESE were recruited in this study. Related data, including age, BMI, the presence of Klinefelter's syndrome and varicocele, cryptorchidism, mean testicular volume, hormonal profile (total testosterone (TT), follicle-stimulating hormone (FSH), luteinising hormone (LH), inhibin B (INHB)), testicular histology and surgical duration, were collected and analysed...

REVIEW
Robert Oates
It is currently unclear whether an adolescent with 47,XXY Klinefelter syndrome will be better off having testicular sperm extraction (TESE) performed in an effort to 'preserve fertility' for the future or, alternatively, should be advised to simply wait until adulthood when he and his partner are ready to begin a family. This report will provide data suggesting that there is no obvious 'preservation' benefit and that recommending TESE to the 47,XXY boy and his parents may not be as helpful as it might appear and may be overly aggressive...

Men with non-obstructive azoospermia (NOA) can achieve fertility by testicular sperm extraction (TESE) coupled with intracytoplasmic sperm injection (ICSI), the key to which is the successful retrieval of sperm from the testis. Although improved testicular sperm extraction techniques have increased the chances of sperm retrieval, to predict preoperatively the success of sperm retrieval from NOA patients remains challenging. A non-invasive diagnostic technique predicting the presence of sperm in the testis would be useful for avoiding possible surgical intervention...
