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...

: 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...

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...

STUDY QUESTION: Should fertility preservation be offered to children with Klinefelter syndrome (KS)? SUMMARY ANSWER: Current evidence shows that fertility preservation should not be offered to adolescents with KS younger than 16 years because of lower retrieval rates for germ cells by testicular sperm extraction (TESE) compared with retrieval rates for adolescents and adults between 16 and 30 years. WHAT IS KNOWN ALREADY: KS, the most common chromosomal disorder in men leading to non-obstructive azoospermia, is caused by the presence of at least one additional X chromosome...

STUDY QUESTION: Can an externally validated model, based on biological variables, be developed to predict successful sperm retrieval with testicular sperm extraction (TESE) in men with non-obstructive azoospermia (NOA) using a large nationwide cohort? SUMMARY ANSWER: Our prediction model including six variables was able to make a good distinction between men with a good chance and men with a poor chance of obtaining spermatozoa with TESE. WHAT IS KNOWN ALREADY: Using ICSI in combination with TESE even men suffering from NOA are able to father their own biological child...

STUDY QUESTION: Which parameters have a predictive value for live birth in couples undergoing ICSI after successful testicular sperm extraction (TESE-ICSI)? SUMMARY ANSWER: Female age, a first or subsequent started TESE-ICSI cycle, male LH, male testosterone, motility of the spermatozoa during the ICSI procedure and the initial male diagnosis before performing TESE were identified as relevant and independent parameters for live birth after TESE-ICSI. WHAT IS KNOWN ALREADY: In reproductive medicine prediction models are used frequently to predict treatment success, but no prediction model currently exists for live birth after TESE-ICSI...

BACKGROUND: Combinations of surgery, radiation therapy, and chemotherapy can achieve high remission rates in patients with cancer, but these treatments can have damaging effects on spermatogenesis. In particular, cytotoxic chemotherapy may lead to irreversible spermatogenic dysfunction. Microdissection testicular sperm extraction (micro-TESE) is the only method that can address infertility in cancer survivors with persistent postchemotherapy azoospermia. METHODS: We included 66 Japanese patients with postchemotherapy azoospermia who underwent micro-TESE for sperm retrieval in this analysis...

Sperm DNA fragmentation (SDF) is used in assisted reproductive technology (ART) programs as an indicator for sperm quality, although there is still a lack of consensus as to its clinical utility. In this retrospective study, we examined intracytoplasmic sperm injection (ICSI) outcomes of 1924 infertile patients who underwent SDF analysis using the sperm chromatin integrity test. ART patients were classified as having low [DNA fragmentation index (DFI) <29%] or high SDF (DFI ≥29%) and by whether or not an intervention [physiological intracytoplasmic sperm injection (PICSI), intracytoplasmic morphologically selected sperm injection (IMSI), testicular sperm extraction (TESE)/testicular sperm aspiration (TESA), frequent ejaculation] was performed...

This retrospective study compared clinical outcomes in men with obstructive and nonobstructive azoospermia after ICSI following testicular sperm extraction and the influence of maternal age. Fertilisation rates, embryo quality, pregnancy rates, miscarriage rates and live birth rates were evaluated. Men with obstructive azoospermia (OA) had significantly higher rates of diploid fertilisation and clinical pregnancy than men with nonobstructive azoospermia (NOA), but miscarriage rates and live birth rates were not significantly different...
