13. Oxidative origin of sperm DNA fragmentation in the adult varicocele
ABSTRACT Purpose: Sperm DNA fragmentation is a major cellular mechanism underlying varicocele-related male infertility. However, the type of DNA fragmentation - whether oxidative or of another nature - remains unknown. Thus, the aim of this study was to evaluate single- and double-stranded sperm DNA fragmentation, and oxidative-induced sperm DNA damage in m

14. The association of seminal oxidation reduction potential with sperm parameters in patients with unexplained and male factor ınfertility
ABSTRACT Purpose: Understanding the effects of high oxidation reduction potential (ORP) levels on sperm parameters will help to identify patients with unexplained and male factor infertility who may have seminal oxidative stress and determine if ORP testing is needed. This study aimed to evaluate the association between seminal ORP and conventional sperm pa

17. [Efeito das técnicas de separação de plasma e de seleção de esperma na recuperação e viabilidade do sêmen de garanhão pônei resfriado por 48h a 5°C]
RESUMO As técnicas de separação do plasma seminal (centrifugação, SpermFilter) e de seleção espermática (Androcoll-E e filtração por lã de vidro) foram aplicadas em 24 ejaculados de seis garanhões da raça Pônei Brasileiro. Após coleta e separação da fração gel, os ejaculados foram diluídos 1:1 com diluente à base de leite em pó. No expe

18. Padronização do Sperm Class Analyzer® (SCA®) para avaliação de espermatozoides equinos criopreservados
RESUMO Objetivou-se, no primeiro experimento, avaliar o efeito da velocidade de captura de imagens de 25Hz, 30Hz e 50Hz na cinética dos espermatozoides equinos criopreservados. Todas as velocidades mostraram-se adequadas para capturar o movimento espermático (P>0,05). No segundo experimento, objetivou-se avaliar o efeito da deposição de sêmen em lâmina

19. Determining an optimal cut-off value for follicle-stimulating hormone to predict microsurgical testicular sperm extraction outcome in patients with non-obstructive azoospermia
ABSTRACT Objective To determine the optimal cut-off value for follicle stimulating hormone (FSH) to predict the outcome of microsurgical testicular sperm extraction (micro-TESE) in patients with nonobstructive azoospermia (NOA). Subjects and methods We included a total number of 180 patients with NOA. The serum level of FSH was determined and all the sub

20. A Rare Case of Bilateral Tubal Ectopic Pregnancy Following Intracytoplasmic Sperm Injection-Embryo Transfer (ICSI-ET)
Abstract Bilateral tubal ectopic pregnancy is a very rare form of ectopic pregnancy. The incidence is higher in women undergoing assisted reproductive techniques or ovulation induction. We report the case of bilateral tubal ectopic pregnancy. The patient was 30 years old and had a 3-year history of infertility; she was referred to the in-vitro fertilization

21. Are specialized sperm function tests clinically useful in planning assisted reproductive technology?
CASE STUDY 40-year-old male patient and 32-year-old female partner, with a history of primary infertility of two years duration. The workup revealed idiopathic mild oligoasthenotheratozoospermia, and no apparent female infertility factors. The couple has failed three intrauterine insemination (IUI) cycles, planning more IUI cycles but also considering in vit

24. Avance genético y políticas de anonimato
Resumo Nos últimos anos, o número de tratamentos de reprodução assistida com doação de gametas (óvulos e/ou espermatozoides) aumentou na Argentina. A filiação por técnicas de reprodução assistida heteróloga interroga a tradicional “herança sanguínea”, objeto de estudo privilegiado das ciências sociais. Nas últimas décadas, o paradigma d
