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. Reproductive effects of the psychoactive beverage ayahuasca in male Wistar rats after chronic exposure
Abstract Ayahuasca is a psychoactive beverage used ancestrally by indigenous Amazonian tribes and, more recently, by Christian religions in Brazil and other countries. This study aimed to investigate the reproductive effects of this beverage in male Wistar rats after chronic exposure. The rats were treated by gavage every other day for 70 days at 0 (control)

3. 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,

4. Efficacy of spermatic vein ligation in patients affected by high grade left varicocele
Purpose: To study the effect of high grade varicocele treatment in infertile patients. Materials and Methods: Seventy-five patients were selected by the following criteria: infertility persisting for more than 1 year; abnormal semen parameters; no other infertility-related disease; no obvious causes of infertility in the subject’s partner; basal eco-col

5. Surgery or embolization for varicoceles in subfertile men
BACKGROUNDA varicocele is a meshwork of distended blood vessels in the scrotum, usually left-sided, due to dilatation of the spermatic vein. Although the concept that a varicocele causes male subfertility has been around for more than 50 years now, the mechanisms by which a varicocele would affect fertility have not yet been satisfactorily explained. Neither

6. 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

7. 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

8. 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

9. 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

10. 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

11. AVALIAÇÃO CINÉTICA DO SÊMEN DE PIRAPITINGA (Piaractus brachypomus) CONGELADO EM MEIO À BASE DE ÁGUA DE COCO EM PÓ (ACP-104) OU RINGER EM TRÊS MEIOS DE ATIVAÇÃO
The pirapitinga, Piaractus brachypomus (CUVIER, 1818) is a Characidade freshwater fish that inhabits the Amazon and Orinoco River basins. The aim of this study was determinate spermatic motility of cryopreserved sperm of pirapitinga in three different activation solutions. Sperm samples were diluted in four freezing media prepared by a combination of two ext

12. 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
