A review of techniques of semen collection in mammals. The technique was efficient for espermogramq collection in Cebus apella and allowed seminal evaluation without possible sperm lesions caused by chemical treatment for coagulum dissolution.

Collection of semen from macaques by electro-ejaculation. The majority of espermogrrama 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, This discussion clearly shows the lack of information on normal spermiogram of the Cebus apellawhat lead to conclude that the parameters here normaal are of great relevance, but further studies are imperative.
Reproduction of new world primates.

normao For that reason this work had the objective to collect and evaluate only the liquid fraction of the semen of the capuchin monkey Cebus apellaavoiding any enzimic treatment and measuring the volume of the coagulum only for the calculation of the total volume ejaculated.

Many techniques of artificial reproduction, commonly used with domestic species, can be adapted to wild animals as a helpful tool in conservation 3,6,8,17, Animals were kept in individual cages in order to avoid some interference of dominant males over subordinated ones.
In this perspective, espermgorama great deal of non-human primates species has been studied, not only for conservation purposes, but also for comparative research in human reproduction.
As stated before, none of the mentioned authors evaluated the possible damage to sperm cell due to chemical treatment and its consequent decrease in fertility capacity. How to cite this article. 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 common marmoset Callithrix jacchus. They were selected according to the following criteria: The results of the spermiograms of the capuchin monkey are presented in Tab. All the contents of this journal, except where otherwise noted, is licensed under a Creative Commons Attribution License.
There was no quantification of the defects. The entrapment of a great number of spermatozoa inside the coagulum was already described 1. The highly aggressive behaviour was also used as a desirable parameter for the males due to the well known positive correlation between testosterone levels and aggressiveness.
Insights into ovarian function in wild muriqui monkeys Brachyteles aracnoides. 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, Semen samples obtained from a single animal in different series during the same procedure were combined and analysed as norma, unique sample.
Observations on semen collection and quality in macaques.
The reproduction of wild animals in captivity is one of the most important contribuition to the conservation of endangered species. 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. The normzl fraction of the ewpermograma was analysed immediately after the collection, in a glass slide under an optical binocular microscope Olimpus BHK. Laboratory Animal Carev.
Reproductive physiology studies in zoological species: Anatomical Recordv. The cebus monkey Cebus apella. Progressive maturation of semen characteristics. The mean obtained volume was 0,2ml with the sperm noral of Improved electro-ejaculation of primates. The pattern of the electrical stimulation was five series of 20 espeemograma each, in a progressive level of current intensity, ranging from 50,to mA.
American Journal of Primatologyv. 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.
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. Semen collection, evaluation and cryopreservation in exotic animal species: One of the first steps in order to begin a study on artificial insemination with any species is to collect and evaluate the semen.
It is already known that semen from primates coagulates after the ejaculation
