1. The combined effect of lifestyle intervention and antioxidant therapy on sperm DNA fragmentation and seminal oxidative stress in IVF patients: a pilot study
ABSTRACT Purpose: Sperm DNA fragmentation (SDF) and seminal oxidative stress are emerging measurable factors in male factor infertility, which interventions could potentially reduce. We evaluated (i) the impact of lifestyle changes combined with oral antioxidant intake on sperm DNA fragmentation index (DFI) and static oxidation-reduction potential (sORP), a

2. Vasectomy re-reversal: effectiveness and parameters associated with its success
ABSTRACT Introduction: When the vasectomy reversal (VR) fails, and the patient desires natural conception with his sperm, vasectomy re-reversal (VRR) is the only alternative. Purpose: To determine the VRR effectiveness and whether specific parameters can be associated with its success. Materials and Methods: We retrospectively evaluated 18 consecutive vas

6. 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

7. 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

10. [Eficácia da associação TES-TRIS ou TRIS com lipoproteína de baixa densidade sobre a longevidade in vitro de sêmen refrigerado de búfalos]
RESUMO Este estudo investigou in vitro a eficácia de quatro diferentes extensores (TES-TRIS e TRIS com lipoproteína de baixa densidade - LDL, nas concentrações de 10 ou 5%) sobre a longevidade espermática de búfalos no processo de refrigeração a 5ºC. A motilidade espermática foi avaliada a cada 24 horas até 72 horas de incubação, por sistema com

11. Cryopreservation of semen from goats fed a diet supplemented with flaxseed
RESUMO O objetivo com o estudo foi avaliar o efeito da inclusão de semente de linhaça na dieta de machos caprinos sobre a resistência do sêmen frente ao processo de criopreservação. Foram utilizados 16 machos, os quais foram distribuídos em quatro grupos e receberam dieta suplementada com 0, 4, 8 e 12% de semente de linhaça, durante um período de 60

12. Intensive use of IVF by large-scale dairy programs
Abstract The number of embryos produced by in vitro fertilization (IVF) has grown exponentially in recent years. Recently, for the first time, the number of embryos produced and transferred in vitro was significantly higher than the number developed in vivo worldwide. In this context, a particular boost occurred with ovum pick-up (OPU) and in vitro embryos p
