| It has been reported that boron causes changes in various systems, including the male reproductive system. Residents in some towns in northern Chile were consuming a few years ago in the drinking water 20 times more than the amount established as permissible limit by WHO. This study evaluates the effects in an animal model of high intake of boron on the testis. Boron was administered in the drinking water. Twenty male mice (Mus domesticus), sexually mature, were used, divided into 2 groups: the experimental group was given Boron at a dose of 12 mg/L, and the control group 0.6 mg/L, for 42 days. Sections of testis were obtained for: HE staining (Morphometry and Histopathology), Immunohistochemistry (Cox-2), Mallory and Picrosirious stain (evaluation of... |

| ABSTRACT: Bovine genital campylobacteriosis (BGC) is a venereal disease caused by Campylobacter fetus subsp. venerealis. In countries with large cattle herds, such as Brazil, where the use of natural breeding as a reproductive strategy is a common practice, BGC is considered an important cause of reproductive failure and economic losses. In these cases, the bull is the asymptomatic carrier of the bacterium and the infected females can have infertility and even abortions. The techniques for the diagnosis of C. fetus are isolation in culture medium and identification by biochemical tests, immunofluorescence, immunoenzymatic assays and molecular techniques. Disease control is based on vaccination with bacterins. This review described the epidemiology,... |

| Abstract: The objective of this work was to evaluate sperm cell motility after intrafollicular artificial insemination (IFAI) in vivo or after incubation in follicular fluid in vitro. In the in vivo experiment, IFAI was performed, followed by the recovery of follicular content 1 to 4 hours later, in order to assess sperm motility. In the in vitro experiment, spermatozoa from a pool of commercial frozen-thawed semen were evaluated for their kinetics after incubation for 1 or 3 hours, either pure (pool, control group) or in follicular fluid (FF). A low motility of sperm cells was observed in the FF samples, both in vitro and in vivo. In vitro, the main parameters negatively affected in the sperm cells incubated in FF, compared with the control, were: total... |

| ABSTRACT Osteoarthritis and osteochondrosis are highly correlated to reproductive failure in bulls. This study aimed to evaluate the carpal, tarsal and interphalangeal lesions in beef zebu bulls on semen collection regimen. Twenty-one beef cattle bulls, in a total of forty-one animals, were split into three age-based groups: animals from two to four years old (GI), from more than four to eight years old (GII) and above eight years old (GIII). The clinical findings were conformational changes of limbs, synovial effusion, peripheral venous engorgement of joints and prolonged decubitus. The total population showed moderate clinical manifestation and radiographic score. The GIII presented more severe joint lesions. Carpi and tarsi regions had discrete to... |

| A study on the occurrence of epididymal lithiasis (EL) in Gallus gallus domesticus of different breeds and from different geographical regions of Brazil was carried out. Forty breeding roosters were collected in the states Santa Catarina, São Paulo, Minas Gerais, Espírito Santo and Goiás, representing two specific pathogen free Leghorn lines (SPF), one commercial Leghorn layer breeder (Hy-Line) line, two commercial broiler breeder lines (Ross and Cobb), and two backyard chicken flocks. In commercial poultry breeders, EL was observed mainly after 55 weeks of age, and lithus resulted in lower fertility caused by inadequate maturation of spermatozoa and testicular atrophy, which evolved to more severe testicular dysfunction at 100 weeks of age. One hundred... |

| Resumo: A hidrossalpinge é um distúrbio que acomete a tuba uterina de várias espécies e se caracteriza pelo acúmulo de líquido seromucoso na cavidade do órgão. A presença de hidrossalpinge pode comprometer parcial ou completamente a fertilidade da fêmea dependendo da sua ocorrência uni ou bilateral, respectivamente. Geralmente identificada post-mortem, esta condição patológica é pouco diagnosticada in vivo, principalmente em animais cuja palpação retal não pode ser realizada. Aparentemente saudáveis, as cabras com hidrossalpinge podem apresentar como sinal da enfermidade, retornos sucessivos ao cio (estro). Não obstante, algumas permanecem improdutivas no rebanho até dois anos de idade ou mais. Este fato demonstra a necessidade de avaliações... |

| The objective of the present study was to determine if exposure of cervical mucus to air during specular examination could modify mucus pH. Detection of changes is justified because of their possible interference with sperm-mucus interaction, since an acidic pH is unfavorable to sperm penetration and is associated with infertility due to the cervical factor. Twenty women with good quality mucus were evaluated. pH measurements of ecto- and endocervical mucus were made in situ using a glass electrode after 0-, 5- and 10-min exposure to air. There was a progressive alkalinization of mucus pH. Mean values of ectocervical mucus pH were 6.91, 7.16 and 7.27, while mean values of endocervical mucus pH were 7.09, 7.34 and 7.46 at 0, 5 and 10 min, respectively.... |

| The morphological characteristics and haematological studies were studied in fifteen male albino rats (Wistar Strain) aged between 12 and 14 weeks and with a body weight of 150- 180g. The rats were allowed to feed on commercially prepared rat pellet and provided with fresh water ad libitum. The rats were divided into three groups; the rats were in groups A, B and C of 5 rats each. Group A served as control of the study; Group B was treated with Chloramphenicol at the dose rate of 25mg/kg body weight per os for 20 days; while Group C was treated for 25 days. Semen used in this study was obtained from the caudal epididymides while morphological aberrations were determined from spermatozoa counted after stained with Wells and Awa stain. Results of the... |

| The effect of peritoneal fluid (PF) on the human sperm acrosome reaction (AR) was tested. Sperm was pre-incubated with PF and the AR was induced by calcium ionophore A23187 and a neoglycoprotein bearing N-acetylglycosamine residues (NGP). The AR induced by calcium ionophore was inhibited 40% by PF from controls (PFc) and 50% by PF from the endometriosis (PFe) group, but not by PF from infertile patients without endometriosis (PFi). No significant differences were found in the spontaneous AR. When the AR was induced by NGP, pre-incubation with PFc reduced (60%) the percentage of AR, while PFe and PFi caused no significant differences. The average rates of acrosome reactions obtained in control, NGP- and ionophore-treated sperm showed that NGP-induced... |

| Endometriosis is a progressive estrogen-dependent disease affecting women during their reproductive years. The objective of the present study was to investigate whether endometriosis is associated with stress parameters. We determined cortisol and prolactin levels in serum, peritoneal and follicular fluid from infertile women with endometriosis and fertile women without the disease. The extent of the disease was staged according to the revised American Fertility Society classification (1997). Serum and peritoneal fluid were collected from 49 women aged 19 to 39 years undergoing laparoscopy. Eighteen women had stage I-II endometriosis and 10 had stage III-IV. Controls were 21 women undergoing laparoscopy for tubal sterilization. Follicular fluid was... |

| The objective of this study was to investigate the causes of the repeat breeder syndrome comparing clinical signs and postmortem findings in beef cows. The identification of factors affecting the reproductive tract can support decisions as to whether treatment of repeat breeder cows is justifiable than culling. Since all animals were submitted to clinical examination before being slaughtered, this study has a differential approach when compared with others, where genital tracts from abattoir were examined. In this study, 130 crossbred cows and heifers that have failed to conceive after three or more services were identified, submitted to a clinical examination and blood collection for karyotyping and sent to an abattoir. postmortem examinations included... |

| Ten cycling Nigerian West African Dwarf (WAD) ewes were used to determine the effect of Trypanosoma congolense infection on the estrous cycle. The estrus of ewes were synchronized using intravaginal progesterone sponges and divided into 2 groups (A and B) of 5 ewes each after 54 days (3 cycles). The ewes in group A were inoculated with blood containing approximately 5×105 trypanosomes per ml of blood while ewes in group B served as the uninfected control. All the ewes were monitored from infection till the end of the study (56 days). Ewes in the infected group had silent estrus with clinical trypanosomosis that was characterized by undulating parasitemia, intermittent pyrexia, anemia and weight loss. There was no statistical (p > 0.05) difference... |

| Varicoceles are abnormal tortuosity and dilatation of the veins of the pampiniform plexus that drain the testis.The pathophysiology of testicular damage in varicocele has not been completely understood. However there is an increasing body of evidence pointing towards the role of reactive oxygen species and oxidative stress in the pathogenesis of varicocele related subfertility. In the present study we examined the role of proanthocynidin-rich ethanol extract of grapefruit seed as an antioxidant in protecting the testis against damage in experimental varicocele. Three groups of rats were constructed as the first group had intact rats; experimental bilateral varicoceles were established by complete ligation of the left and right main spermatic veins in the... |
