2. 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

3. 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

4. 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

5. 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

6. Challenges to increase the AI and ET markets in Brazil
Abstract Artificial insemination (AI) and embryo transfer (ET) are the most widely used biotechnologies in the world with the goal of increasing genetic gain and improving reproductive efficiency of beef and dairy herds. The protocols for ovulation synchronization for timed AI (TAI) or ET (TET) are tools that allow artificial insemination or transfer of a hi

7. Protein profile as a quality indicator of cryopreserved semen from Tambaqui Colossoma macropomum (Cuvier, 1818)
Resumo O objetivo desse estudo foi de avaliar a associação entre a presença de proteínas no plasma seminal do tambaqui Colossoma macropomum (Cuvier, 1818) com indicadores de qualidade seminal pós-descongelamento. O semen foi criopreservado com diluidor a base de BTS com 8% DMSO. Uma amostra de 200 µL de semen de cada animal foi diluída em 800 µL de B

8. 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

9. Concentration of soybean lecithin affects short-term storage success of goat semen related with seminal plasma removal
Abstract The objective of this study was to investigate the need of seminal plasma removal for short-term cooling of buck semen in soybean lecithin (SL) based extender. Each pool was divided equally, and one half was subjected to centrifugation to remove seminal plasma (SP-), while the other half remained with seminal plasma (SP+). Then, both SP+ and SP- sam

10. Effect of glycerol, n, n-dimethylformamide and n-methyl-2-pyrrolidone on rabbit sperm stored at 4 °C and 16 °C
Abstract Artificial insemination with cooled semen is the most common practice in rabbit farms and any improvement on it helps to increase the efficiency and productivity of rabbit meat farms. Therefore, the aim of this study was to assess whether different cryoprotectant agents (CPA) as glycerol, N, N-Dimethylformamide (DMF) and N-Methyl-2-Pyrrolidone (NMP)

11. Reproductive toxicity of neem seeds (Azadirachta indica) in male quail (Coturnix coturnix japonica)
RESUMO: Considerando que o neem (Azadirachta indica A. Juss.) causa efeitos deletérios na fertilidade, objetivou-se avaliar o efeito da alimentação com sementes de neem sobre a qualidade seminal, parâmetros biométricos e morfometria testicular com codornas (Coturnix coturnix japonica Linnaeus, 1758) com 90 dias de idade, como modelo experimental.

12. Response of duck breeders to dietary L-Carnitine supplementation during summer season
Abstract: A total number of 300 (225 ducks and 75 drakes) Sudani ducks, 28-wk-old were divided into five groups to investigate the effects of dietary L-carnitine (LC) supplementation on productive, hatching and physiological performance as well as nutrients digestibility coefficients. The results indicated that the productive performance and Semen quality pa
