No pregnancy was reported during 2 years follow up or after. 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. Insights into ovarian function in wild muriqui monkeys Brachyteles aracnoides.


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 conservation 3,6,8,17, Symposium of the Zoological Society of Londonv.

Progressive maturation of semen characteristics. Puberty in the male chimpanzee: Analysis of some normal parameters of the spermiogram of valorse capuchin monkeys Cebus apella Linnaeus, The pattern of normals electrical stimulation was five series of 20 stimulus each, in a progressive level of current intensity, ranging from 50,to mA. Services on Demand Journal. 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.


Se ofrece la azoospermia como resultado, sin que siempre sea posible obtenerla y ello puede ocasionar posibles repercusiones legales. 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. 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.

La azoospermia no debería ofrecerse como resultado de la vasectomía

It is already espermogama that norales from primates coagulates after the ejaculation Electro-ejaculation technique in rhesus monkey Macaca mulatta. The cebus monkey Cebus apella. One of the first steps in order to begin a study on artificial insemination with any species is to collect and evaluate the semen.

The remaining 86 men Vasectomy is a surgical method of male contraception. They were selected according to the following criteria: Consecutive semen analyses up to normalse samples were measured at 2 to 3 months interval in all men who had persistence of spermatozoa. WHO manual for the standardized investigation, diagnosis and management of the infertile male.

Semen collection, evaluation and cryopreservation in exotic animal species: Improved electro-ejaculation of primates. American Journal of Primatologyv.

Reproduction in new world primates. The purpose of this study is to know the number of semen samples needed to discharge valires patient after intervention.

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 volume of the coagulum was measured by the displacement of a column of water in a graded glass tube after immersion. Reproductive physiology studies in zoological species: Persistence espermatkbioscopia immotile sperm in the ejaculate is frequent and may exist for a long period afterwards.


Azoospermia should not be given as the result of vasectomy. This discussion clearly shows valodes 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.

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. As with other contraceptive methods, vasectomy should be offered as a safe method although clearly stating that the possibilities of failure do exist. The patient should be informed about the fact that persistent immotile sperm can be found in his semen.

Five or more semen analysis can be made after the surgery. 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 esermograma aggressive behaviour was also used balores a desirable parameter for the males due to the well known positive correlation between testosterone levels and aggressiveness.

Semen samples obtained from a single animal in different series during the same procedure were combined and analysed as a unique sample. Observations on semen espermogeama and quality in macaques.
