As with other contraceptive methods, vasectomy should be offered as a safe method although clearly stating that the possibilities of failure do exist. Persistence of immotile sperm in the ejaculate is frequent and may exist for a long period afterwards.

Semen samples obtained from a single animal in different series during the same procedure were combined and analysed as a unique sample. Immotile sperm count of How to cite this article. Contracept Reprod Health Care.

Reproduction in new world primates. 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.

Semen characteristics of espermatobioscopiz adult male chimpanzee Pan troglodytes. 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, espermatobloscopia and cryopreservation in exotic animal 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.

One of the first steps in order to begin a study on artificial insemination with any species is to collect and evaluate the semen. Rspermatobioscopia 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.

Semen evaluation in capuchin monkeys Cebus apella. The purpose of this study is to know the number of semen samples needed to discharge a patient after intervention.

Consecutive semen analyses up to 5 samples were measured at 2 to 3 months interval in all men who had persistence of spermatozoa. American Journal of Primatologyv. Observations on semen espermogeama and quality in macaques. Five or more semen analysis can be made after the surgery.

La azoospermia no debería ofrecerse como resultado de la vasectomía

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. This difference is obviously related to the fact that we only evaluated the liquid fraction while the other authors studied the whole ejaculate.

Progressive maturation of semen characteristics. 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. 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.

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.

Collection of semen from macaques by electro-ejaculation. 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: The remaining 86 men Azoospermia is offered as result of the technique and this is not always attained, resulting in legal matters.
