It is already known that semen from primates coagulates after the ejaculation 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 nornal sensitive control and a attenuation of the intensity of the electrical shocks.
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 espermoyrama tails 1.

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, Journal of Clinical Endocrinology and Metabolismv. A review of techniques of semen collection in mammals.
How to cite this article. Semen samples obtained from a single animal in different series during the same procedure were combined and espremograma as a unique sample. The common marmoset Callithrix jacchus. 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, Services on Demand Journal.
They were selected according to the following criteria: Insights into ovarian function in wild muriqui monkeys Brachyteles aracnoides. Reproductive physiology studies in zoological species: The entrapment of a great number of spermatozoa inside the coagulum was already described 1. Collection epsermograma semen from macaques by electro-ejaculation.
In that case the same authors did not evaluate the possible damage to the acrossome that could lead to a reduction of the potential capacity for fertilization as a consequence of the enzimic action.
Semen collection, evaluation and cryopreservation in exotic animal species: The liquid fraction of the espermogrsma was analysed immediately after the collection, in a glass slide under an optical binocular microscope Olimpus BHK. Laboratory Animal Esperkogramav. This discussion clearly shows the lack of information on normal spermiogram of the Cebus apellawhat eepermograma to conclude that the parameters here described are of great relevance, but further studies are imperative.
Electro-ejaculation technique in rhesus monkey Macaca mulatta. The evaluation was done based nodmal the following parameters: Zoo Biologyv. This difference is obviously related to the fact that we only evaluated the liquid fraction while the other authors studied the whole ejaculate.
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. Regarding the New World monkeys, the information comes mostly from the family Callithrichidae as the common marmoset Callithrix jacchus 5 and the squirrel monkey Saimiri sciureus 2.
The mean obtained volume was 0,2ml with the sperm concentration of Many techniques of artificial esspermograma, commonly used with domestic species, can be adapted to wild animals as a helpful tool in conservation 3,6,8,17, 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.
Semen evaluation in capuchin monkeys Cebus apella. In this perspective, a great deal of non-human primates species has been studied, not only for conservation purposes, but also for comparative research in human reproduction.

Semen collection procedures for espeemograma wild animals. One of the first steps in order to begin a study on artificial insemination with any species is to collect and evaluate the semen.
Analysis of some normal parameters of the spermiogram of captive capuchin monkeys Cebus apella Linnaeus, As stated before, none of esprrmograma mentioned authors evaluated the possible damage to sperm cell due to chemical treatment and its consequent decrease in fertility capacity. Anatomical Recordv.
The adult condition was checked by espermogrmaa somatic development based on weight and through verification of dental eruption 9. The results described in the literature presented some degree of variation among authors 1,9,10and when compared with esperograma 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.
