1. Semen quality from patients affected by seminomatous and non-seminomatous testicular tumor
ABSTRACT Testicular cancer is considered a rare disease affecting approximately 1% to 2% of the male population. This neoplasm has a cure rate of over 95%; as a result, a major concern is the future of fertility of carriers from this disease. There are several histological subtypes of testicular tumors; however, the Testicular Germ Cell Tumors (TGCTs), compr

2. Efeitos do Hydrosalpinx no Falho de Implantação Endometrial: Avaliar a salpingectomia nas mulheres em curso de Fertilização in vitro
Abstract Hydrosalpinx is a disease characterized by the obstruction of the salpinx, with progressive accumulation in the shape of a fluid-filled sac at the distal part of the tuba uterina, and closed to the ovary. Women with hydrosalpinges have lower implantation and pregnancy rates due to a combination of mechanical and chemical factors thought to disrupt t

3. 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

6. 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

7. Utilização da lipoproteína de baixa densidade, em diferentes concentrações, em meio diluidor para criopreservação do sêmen ovino
RESUMO A utilização da gema de ovo dificulta a padronização de meios diluidores e apresenta riscos biológicos. Assim, este estudo avaliou diferentes concentrações da lipoproteína de baixa densidade (LDL), em substituição à gema de ovo, para a confecção de diluentes para criopreservação espermática em ovinos. Foram utilizados um diluidor contr

8. Bovine semen thermoresistance tests and their correlation with pregnancy rates after fixed-time artificial insemination
RESUMO O objetivo do presente estudo foi determinar se há ou não correlação entre testes de termorresistência (TT) após descongelamento do sêmen e taxa de prenhez (TP) após inseminação artificial em tempo fixo (IATF). Quatro diferentes TT foram realizados nas 10 amostras utilizadas para a IA; um teste rápido (RTT) (30min/46°C) e três testes lent

9. Comparison of sperm selection techniques in donkeys: motile subpopulations from a practical point of view
Abstract The aim of this study was to compare the post-thaw distribution of motile sperm subpopulations, following simple or colloid centrifugation. A new analysis was used to evaluate the available number of sperm from each subpopulation after each centrifugation protocol. Frozen/thawed semen samples were divided into the following after-thawing treatments:

10. Effect of adenosine concentration on quality of cooled ram semen
ABSTRACT This study analyzed the adenosine concentration on quality of ram semen in different refrigerated storage times at 5 °C. The design was in blocks with repeated-measures factorial design. Five levels of adenosine and four refrigeration times were considered as fixed effects and the animal as random effect (block). Ram semen was diluted with Andromed

11. Can we use LDL instead of egg yolk in BotuCrio® extender to cryopreserve sperm from the Mangalarga Marchador stallion?
Abstract The objective of this study was to compare the BotuCrio® extender with the Merk - egg yolk and the INRA 82 modified by the inclusion of acetamide, methyl cellulose and trehalose in substitution of glycerol for freezing equine semen. The semen was diluted after centrifugation to obtain 100 x 106 of sperm/ml in: BotuCrio® (control); Merk - egg yolk

12. Storage of boar semen at 16-18 °C in the long-term commercial extender prepared with deionized water or nanowater
Abstract The aim of this study was to assess the usefulness of nanowater (NW; water declusterized using cold plasma treatment) as a diluent for a commercial boar semen extender during the 15-day storage (Days 1 to 15) at 16-18 °C. Ejaculates collected from 8 boars were subjected to the standard evaluation and then diluted in the extender prepared with deion
