Insights into ovarian function in wild muriqui monkeys Brachyteles aracnoides. 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.

How to cite this article. The volume of the coagulum was measured by the displacement of a column of water in a graded glass tube after immersion. 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 vslores reproduction.

Progressive maturation of semen characteristics. The reproduction of wild animals in nirmal is one of the most important contribuition to the conservation of endangered species. 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 espermatobioscpia 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.

Immotile sperm count of Consecutive semen analyses up to 5 samples were measured at 2 to 3 months interval in all men who had persistence of spermatozoa. 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.

The remaining 86 men 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.


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 stimulus each, in a progressive level of current intensity, ranging from 50,to mA. Se ofrece la azoospermia como resultado, sin que siempre sea posible obtenerla y ello puede ocasionar posibles repercusiones legales. The results described in the literature normalss 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.

In the informed consent azoospermia should not be a concern as it is frequent to find immotile sperm in the ejaculate and this is an espermatobioscoopia issue.

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. Observations on semen espermogeama and quality in macaques. Semen characteristics of the adult male chimpanzee Pan troglodytes. Collection of semen from macaques by electro-ejaculation. Contracept Reprod Health Care. Journal of Clinical Endocrinology and Metabolismv.

To identify sperm count on semen analysis at time of discharge.

WHO manual for the standardized investigation, diagnosis and management of the infertile male. Azoospermia should not be given as the result of vasectomy.

Retrospective study of men who underwent vasectomy in a month period with a 2 year follow up. Azoospermia is offered as result of the epsermatobioscopia and this is not always attained, resulting in legal matters.


Semen collection procedures for captive wild animals. Reproduction of espermgorama world primates. No pregnancy was reported during 2 years follow up or after. Los estudios seminales se repitieron con intervalos aproximados de tres meses hasta obtener un informe negativo. Puberty in the male chimpanzee: The patient should be informed about the fact that persistent immotile sperm can be found in his 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.


Persistence of immotile sperm in the ejaculate is frequent and may exist for a long period afterwards. It is already espermogama that semen from primates coagulates after the ejaculation Electro-ejaculation technique in rhesus monkey Macaca mulatta.

Reproduction in new world primates. 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.

This difference is obviously related to the fact that we only evaluated the liquid fraction while the other authors studied the whole ejaculate. Nine adult males Cebus apella were studied. Semen evaluation in capuchin monkeys Cebus apella.

The esermograma aggressive behaviour was also used as a desirable parameter for the males due to the well known positive correlation between testosterone levels and aggressiveness.

Improved electro-ejaculation of primates. American Journal of Primatologyv. The cebus monkey Cebus apella. 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 to wild animals as a helpful tool in espermatobioscoopia 3,6,8,17, Symposium of the Zoological Society of Londonv.

Services on Demand Journal. They were selected according to the following criteria: Reproductive physiology studies in zoological species: Vasectomy is a surgical method of male contraception.
