2. Development of single tubing-type canister for cryo-storage of bull semen and their effect on sperm motility and viability
The objective of this study was to evaluate the potential of using single tubing-type canister on sperm quality. Semen was collected from the Bali cattle bull by electroejaculation technique and was cryopreserved in liquid nitrogen using slow freezing cryopreservation method. Two type of canister volume was used in this study; commercial canister (342.25π x

3. Viability of bull spermatozoa collected from the epididymis stored at 18-20°C
The aim of this study was to evaluate the viability of bull spermatozoa collected from the cauda epididymis stored at 18-20°C, which were compared with semen collected by electro-ejaculation method and preserved at 5°C. Ten pairs of testes from Tabapuã bulls were removed by orchiectomy and stored for 6 (G6), 12 (G12), 18 (G18), 24 (G24) and 30 (G30) h at

4. Caracterização do sêmen, do plasma seminal e concentração sérica de testosterona em cervo sambar (Cervus unicolor) em cativeiro na primavera / Characterization semen, of seminal plasma and concentration serum testosterone in sambar deer (Cervus unicolor) in captivity in the spring
The objective of this study was to evaluate the framework sperm and protein seminal plasma and endocrine profile in deer bred in captivity. Four males aged between 12 and 36 months were evaluated. In four times at intervals of seven days, gave the weight (60.5 to 89.0 kg) and body mass index (93.07 kg/m2 to 126.56 kg/m2). There were four semen samples per an

6. Análise descritiva do perfil espermático do tamanduá-bandeira (Myrmecophaga tridactyla Linnaeus, 1758) de cativeiro / Spermatic profile of captive Giant Anteater (Myrmecophaga tridactyla Linnaeus, 1758)
O objetivo do presente estudo é descrever as características físicas, químicas, morfológicas e funcionais do sêmen do tamanduá-bandeira (Myrmecophaga tridactyla) em cativeiro. Estes resultados representam um dos primeiros requisitos para o conhecimento das características seminais da espécie, visando, em médio prazo, a aplicação de técnicas de r

7. Avaliação andrológica e criopreservação de sêmen de pumas (Puma concolor Linnaeus, 1771) adultos / Andrologic evaluation and cryopreservation of adult cougars (Puma concolor Linnaeus, 1771) semen
The wild felines is one of the most endangered species of the world and its population is affected by some factors that vary geographically because of the alduteration of their habitat, food available, strong hunt pressure or even the low population density. Assisted reproduction techniques such as gametes cryopreservation and in vitro fertilization are fund

8. Male infertility in spinal cord trauma
Every year there are 10 thousand new cases of patients victimized by spinal cord trauma (SCT) in the United States and it is estimated that there are 7 thousand new cases in Brazil. Eighty percent of patients are fertile males. Infertility in this patient group is due to 3 main factors resulting from spinal cord lesions: erectile dysfunction, ejaculatory dis

9. Changes in the fecal concentrations of cortisol and androgen metabolites in captive male jaguars (Panthera onca) in response to stress
In the present study we determined the efficacy of the measurement of fecal cortisol and androgen metabolite concentrations to monitor adrenal and testicular activity in the jaguar (Panthera onca). Three captive male jaguars were chemically restrained and electroejaculated once or twice within a period of two months. Fecal samples were collected daily for 5

10. Evaluation of a segmented rectal probe and caudal epidural anesthesia for electroejaculation of bulls
Changes in concentrations of cortisol and progesterone in serial blood samples were used to quantify a stress response to different methods of electroejaculation in 10 Hereford bulls. Treatments included restraint (control), and electroejaculation using rectal probes with segmented electrodes or conventional nonsegmented electrodes, with or without lidocaine

11. Electroejaculation: its technique, neurological implications and uses.
An improved technique for electroejaculation is described, with the results of applying it to 84 men with spinal injuries and five men with ejaculatory failure from other causes. Semen was obtained from most patients, but good semen from very few. Only one pregnancy has yet been achieved. The technique has diagnostic applications.

12. A comparison of electroejaculation and epididymal sperm collection techniques in stallions
The purpose of this study was to evaluate 2 methods of semen collection that could be used as terminal procedures in stallions with irreparable conditions, such as fractures or colic. Electroejaculation was attempted under general anesthesia. Forty-eight hours later, the ponies were castrated and 2 different epididymal sperm collection techniques were attemp
