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 acceptable issue.

The remaining 86 men Contracept Reprod Health Care. The volume of the coagulum was measured by the displacement of a column of water in a graded glass tube after immersion. 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.

No pregnancy was reported during 2 years follow up or after. 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.

Persistence of immotile sperm in the ejaculate is frequent and may exist for a long period afterwards. One of the first steps in order to begin a study on artificial insemination with any species is to collect and evaluate the semen.

Se ofrece la azoospermia como resultado, sin que siempre sea posible obtenerla espetmatobioscopia ello puede ocasionar posibles repercusiones legales. Retrospective study of men who underwent vasectomy in a month period with a 2 year follow up. 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 evaluation in capuchin monkeys Cebus apella.

American Journal of Primatologyv. Services on Demand Journal. Five or more semen analysis can be made after the surgery. This discussion clearly shows the lack of information on normal spermiogram of the Cebus apellawhat lead to conclude that the parameters here described are espermatobiosckpia great relevance, but further studies are imperative.

Nine adult males Cebus apella were studied. WHO manual for the standardized investigation, diagnosis and management of the infertile male.

Reproductive physiology studies in zoological species: In this perspective, a great deal of non-human primates species has been studied, not notmales for conservation purposes, but also for comparative research in human reproduction. They were selected according to the following criteria: Collection of semen from macaques by electro-ejaculation.
