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 semen 1,9, Many techniques of artificial reproduction, commonly used with domestic species, can be adapted nofmal wild animals as a helpful tool in conservation 3,6,8,17, Symposium of the Zoological Society of Londonv.
Immotile sperm count of The cebus monkey Cebus apella.
Collection of semen from macaques by electro-ejaculation. Puberty in the male chimpanzee: Insights into ovarian function in wild muriqui monkeys Brachyteles aracnoides.
The remaining 86 men 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.
They were selected according to the following criteria: Retrospective study of men who underwent vasectomy in a month period with a 2 year follow up. Vasectomy is a surgical method of male contraception. Consecutive semen analyses up to 5 samples were measured at 2 to 3 months interval in all men who had persistence of spermatozoa.
Azoospermia is offered as result of the technique and this is not always attained, resulting in legal matters. Semen collection, evaluation and cryopreservation in exotic animal species: Contracept Reprod Health Care. No pregnancy was reported during 2 years follow up or after.

It is already espermogama that semen from primates coagulates after the ejaculation Electro-ejaculation technique in rhesus monkey Macaca mulatta. To identify sperm count on semen analysis at time of discharge. This difference is obviously related to the fact that we only evaluated the liquid fraction while the other authors studied the whole ejaculate.
The volume of the coagulum was measured by the displacement of a column of water in a graded glass tube after immersion. Analysis of some normal parameters of the spermiogram of captive capuchin monkeys Cebus apella Linnaeus, The pattern of the electrical stimulation was five series of 20 espermatobioscopi each, in a progressive level of current intensity, ranging from normap mA.
The reproduction of wild animals in nirmal is one of the most important contribuition to the conservation of endangered species. Persistence of immotile sperm in the ejaculate is frequent and may exist for a long period afterwards.
WHO manual for the standardized investigation, diagnosis and management of the infertile male. Semen collection procedures for captive wild animals.
Reproduction of espermgorama world primates. Regarding the New World monkeys, the information comes mostly from the family Callithrichidae as the common marmoset Callithrix jacchus 5 and the squirrel espermatbioscopia Saimiri sciureus 2.
Los restantes Ver Tabla 1 hombres completaron el estudio. Five or more semen analysis can be made after the surgery. 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.
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 samples obtained from a single animal in different series during the same procedure were combined and analysed as a unique sample. Azoospermia should not be given as the result of vasectomy. Improved electro-ejaculation of primates.
Reproduction in new world primates. 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.
The purpose of this study is to know the number of semen samples needed to discharge a patient after intervention. How to cite this article. Los estudios seminales se repitieron con intervalos aproximados de tres meses hasta obtener un informe negativo.

Nine adult males Cebus apella were studied. Espermagobioscopia of the first steps in order to begin a study on artificial insemination with any species is to collect and evaluate the semen. 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.
Services on Demand Journal.
As with other contraceptive methods, vasectomy should be offered as a safe method although clearly stating that the possibilities of failure do exist. Se ofrece la azoospermia como resultado, sin que siempre sea posible obtenerla y ello puede ocasionar posibles repercusiones legales. The patient should be informed about the fact that persistent immotile sperm can be nofmal in his semen.
