Improved electro-ejaculation of primates. Reproduction in new world primates. Collection of semen from macaques by electro-ejaculation. Five or more semen analysis can be made after the surgery. Semen collection procedures for captive wild animals.

They were selected according to the following criteria: Progressive maturation of semen characteristics. Regarding the New World monkeys, the information espermatobioscopiw mostly from the family Callithrichidae as the common marmoset Callithrix jacchus 5 and the squirrel monkey Saimiri sciureus 2.


Immotile sperm count of 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. As with other contraceptive methods, vasectomy should be offered as a safe method although clearly stating that the possibilities of failure do exist. American Journal of Primatologyv.

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. Los restantes Ver Tabla 1 hombres completaron el estudio.

The remaining 86 men Semen was collected by electro-ejaculation valorres 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.

WHO manual for the standardized investigation, diagnosis and management of the infertile male. Consecutive semen analyses up to 5 samples were measured at 2 to 3 months interval in all men who had persistence of spermatozoa. Retrospective study of men who underwent vasectomy in a month period with a 2 year follow up.


Observations on semen espermogeama and quality in macaques. 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 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.

Insights into ovarian function in wild muriqui monkeys Brachyteles aracnoides. The reproduction of wild animals in nirmal is one of the most important contribuition to the conservation of endangered species. Reproduction of espermgorama world primates.

To identify sperm count on semen analysis at time of discharge. Contracept Reprod Health Care. 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.

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.

INICIO – Amnios

No pregnancy was reported during 2 years follow up or after. Se ofrece la azoospermia como resultado, sin que siempre sea posible obtenerla y ello puede ocasionar posibles repercusiones legales. This difference is obviously related to the fact that we only evaluated the liquid fraction while the other authors studied the whole ejaculate. 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.


Analysis of some normal parameters of the spermiogram of captive capuchin monkeys Cebus apella Linnaeus, The pattern of the electrical stimulation vvalores five series of 20 stimulus each, in a progressive level of espermatobioacopia intensity, ranging from 50,to mA. Services on Demand Journal. Semen samples obtained from a single animal vaolres different series during the same procedure were combined and analysed as a unique sample. Puberty in the male chimpanzee: 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.

The cebus monkey Cebus apella. The purpose of this study is to know the number of semen samples needed to discharge a patient after intervention. The patient should be informed about the fact that persistent immotile sperm can be found in his semen. Reproductive physiology studies in zoological species: Semen characteristics of the adult male chimpanzee Pan troglodytes. How to cite this article. Azoospermia is offered as result of the technique and this is not always attained, resulting in legal matters.

Nine adult males Cebus apella were studied. The volume of the coagulum was measured by the displacement of a column of water in a graded glass tube after immersion.

Vasectomy is a surgical method of male contraception. One of esprrmatobioscopia first steps in order to begin a study on artificial insemination with any species is to collect and evaluate the semen.
