1. Antioxidant action of alpha lipoic acid on the testis and epididymis of diabetic rats: morphological, sperm and immunohistochemical evaluation
ABSTRACT Introduction Chronic hyperglycemia is caused by diabetes mellitus-committed genital morphophysiology, and oxidative stress is one of the main factors involved in this process. Alpha lipoic acid (ALA) can prevent metabolic and morphological changes in diabetic individuals. Objectives In present study, we evaluated the effects of regular ALA consu

2. Seasonal variation in the reproductive activity of male goats raised under tropical climate conditions
ABSTRACT This study analyzed seasonal variations in the testes, the concentration of sex hormones, the parameters of fresh and thawed semen, and the sexual behavior of male Alpine goats from a temperate region in a tropical climate and possible interference with fertility. The maximum and minimum temperature and luminosity were recorded daily, while seminal,

3. Assessment of viability of sperm cells of Litopenaeus vannamei on cryopreservation
Aiming at assessing the cryopreservation potential of Litopenaeus vannamei sperm cells, 74 spermatophores were manually extracted from the sexually mature individuals. After the toxicity test to define the cryoprotectant concentration, suspensions of spermatic cells were cryopreserved in the groups in freezing solutions comprising different cryoprotectants s

4. Semen and reproductive parameters during some abstinence periods after cigarette smoke exposure in male rats
Cigarette smoking is very widespread globally and can also be implicated in male and female infertility. This study aimed to evaluate the testicular function throughout a complete spermatic cycle during abstinence from cigarette smoke exposure in order to identify a possible residual damage and whether the parameters could recover spontaneously. Male Wistar

5. USO DE DILUENTES ALTERNATIVOS A BAIXAS TEMPERATURAS NA MANUTENÇÃO DA QUALIDADE ESPERMÁTICA DO SÊMEN SUÍNO / USE OF ALTERNATIVE SOLVENTS AT LOW TEMPERATURES IN THE MAINTENANCE OF SPERM QUALITY OF SWINE SEMEN
Countless studies have been conducted with the purpose of improving the conservation of boar semen, either with the use of diluents or alternative temperature ranges, or adding antioxidants or amino acid to the diluent. The present study aimed to define an alternative diluent and temperature preservation of boar semen and evaluate the effects of adding trolo

6. Comportamento sexual, parâmetros seminais e diluição pós-congelamento de sêmen de jumentos (Equus asinus) da raça Pêga / Sexual behavior, seminal parameters and dilution after freezing Pêga breed donkeys (Equus asinus) semen
The aim of this study was to elucidate aspects of asinine behavior from the description of various collections using an artificial vagina and relate this behavior with the seminal parameters. We evaluated also the availability of the formulation of the diluent T2-94 plus dimethylformamide in the protection of sperm cells during cryopreservation of semen from

7. Viability and fertility of cooled equine semen diluted with skimmed milk or glycine egg yolk-based extenders
Two semen extenders were compared for their ability to maintain viability of horse semen during 24 hours of cold preservation, and for the pregnancy rate after artificial insemination. In the experiment 1, five ejaculates from three stallions were split-diluted in either a skimmed milk-based extender (Kenney extender) or a glycine egg yolk-based extender (Fo

8. Puberty and sexual maturity in Anglo-Nubian male goats raised in semi-intensive system
The objective of this study was to characterize the sexual development in Anglo-Nubian male goats raised in semi-intensive system. Eight animals were monitored every fifteen days, from the 12th to the 44th week for age at penis detachment, live weight, scrotal circumference, seminal parameters (volume, aspect, concentration, wave motion, progressive individu

9. Complemental tests in semen and evaluation of the anionic proteins and peptides differentially synthesized in seminal plasma of Nelore bulls classified as sound and unsound for breeding / Testes complementares em sêmen e avaliação da síntese diferencial de proteínas e peptídeos aniônicos em plasma seminal de touros da raça Nelore classificados em aptos e inaptos à reprodução
The main analyses performed routinely to assess the sperm quality are the spermatic motility and morphology for the measurement bulls fertility. Several complementary techniques are used to improve bulls fertility evaluation. Each technique is related to different aspects of sperm quality and their results are not yet fully understood. Four experiments were

10. Efeitos do tratamento com l-alanil-glutamina sobre o estresse oxidativo em ratos jovens submetidos à torÃÃo do cordÃo espermÃtico / Effects of l-alanil-glutamine treatment upon oxidative stress in youn rats subjected to torsion of spermatic cord
The effect of L-alanil-glutamine was tested in a situation of oxidative stress induced by torsion of the spermatic cord. Eighty four male young Wistar rats were distributed randomly in 6 groups: Saline group 1h (GSa1) and Ala-Gln Group 1h (GAg1), animals of these groups were submitted to 1 hour of ischemia and 6 hours of reperfusion and were treated 30 minut

11. Diferentes concentraÃÃes espermÃticas na inseminaÃÃo artificial intra-uterina em suÃnos / Different spermatic concentrations on the intrauterine artificial insemination in swine
The aim of this work was to evaluate the efficiency of the intrauterine insemination (IUI) in swine, considering the conception rate, farrowing rate, litter size (alive, stillborn and mummified) and pig born weight. In the IUI, the females had been inseminated at 24 and 48 hours after the oestrus detection, and had been used the inseminating doses with 500 m

The objective of present work was to study the reproductive characteristics of rheophilic fishes in different period (November, December, and January) of three reproductive years. The study was carry out in the âFish Farming Laboratoryâ of the âEnvironmental Stationâ of Itutinga (CEMIG) and in the âPharmacology and Physiology Laboratoryâ of the DMV- UF
