Very few information on sperm parameters of Cebus apella could be found in literature and they were referred to the whole ejaculate after chemical dissolution of the coagulated fraction of the nkrmal 1,9, The majority of the information concerning basic knowledge of normal reproductive parameters is obtained from Old World monkeys as the chimpanzee Pan troglodytes 4,7 and rhesus Macaca mulatta 11,14, The highly aggressive behaviour was also used as a desirable parameter for the males espermogrma to the well known positive correlation between testosterone levels and aggressiveness.
Nine adult males Cebus apella were studied. The technique was efficient for semen collection in Cebus apella and allowed seminal evaluation without possible sperm lesions caused by chemical treatment for coagulum dissolution. The results of the spermiograms of the capuchin monkey are presented in Tab.
The pattern of the electrical stimulation was five series of 20 stimulus each, in a progressive level of current intensity, ranging from 50,to mA. Puberty nor,al the male chimpanzee: Laboratory Animal Carev. Semen characteristics of the adult male chimpanzee Pan troglodytes.

Reproductive physiology studies in zoological species: This discussion clearly shows the lack of information on normal spermiogram of the Cebus apellawhat lead to conclude that the parameters here described are of great relevance, but further studies are imperative.
The mean obtained volume was 0,2ml with the sperm concentration of The results described in the literature presented some degree of variation among authors 1,9,10and when compared with our results we could find similar volumes of ejaculate in two of them 0,6 ml 10 and 0,58 ml 1 while the third was more than two fold bigger 1,9 ml 9.

For that reason this work had the objective to collect and evaluate only the liquid fraction of the semen of the capuchin monkey Cebus espermorgamaavoiding any enzimic treatment and measuring the volume of the coagulum only for the calculation of the total volume espermogrxma.
Progressive maturation of semen characteristics. The evaluation was done based on the following parameters: They were selected according to the following criteria: From the obtained ejaculate, we only analysed the liquid fraction in order to avoid any kind of chemical treatment to attain dissolution of the seminal coagulum.
Animals were kept in individual cages in order to avoid some interference of dominant males over subordinated ones.
Semen samples obtained from a single animal in different series during the same procedure were combined and analysed as a unique sample. Anatomical Recordv.

In respect to the sperm cell pathology we found only one work in literature that reports as the most frequent defects the detached heads and tails and the twisted and bent tails 1.
Semen collection, evaluation and cryopreservation in exotic animal species: The adult condition was checked by the somatic development based on weight and through verification of dental eruption 9. The volume of the coagulum was measured by the displacement of a column of water in a graded glass tube after immersion. Semen was collected by electro-ejaculation with a 9 mm diameter bipolar rectal probe connected to a standard bovine electro-ejaculator apparatus adapted to provide a more sensitive control and a attenuation of the intensity of the electrical shocks.

In the family Cebidae there are fewer data in literature, being most of that related to two different species of capuchin monkey Cebus capucinus 10 and Cebus apella 1,9 and more recently to the muriqui Brachyteles aracnoides 12, Reproduction in new world primates. This difference is obviously related to the fact that we only evaluated the liquid fraction while the other authors studied the whole ejaculate. Specifically with the semen from the capuchin monkey it was described that the coagulum must go under enzimic liquefaction because it won’t dissolve spontaneously 1,9, The squirrel monkey Saimiri sciureus.
One of the first steps in order to begin a study on artificial insemination with any species is to collect and evaluate the semen.
