Abstract

A 9.4 mg deslorelin slow-release implant was inserted into an adult, healthy billy goat to achieve temporary infertility and a reduction in sexual behavior. The implant was inserted in late autumn. No significant change in testis size was observed over the following 6 weeks. The endocrine function of the testis, which was examined by stimulation with human chorionic gonadotropin, was also unchanged after 6 weeks compared to the initial examination. Histological examination revealed a preserved spermatogenesis.

In conclusion, the application of a GnRH analogue implant in the adult male goat has no influence on the investigated parameters – and thus probably also on its fertility.

Zusammenfassung

Ein 9,4 mg slow-release Deslorelin-Implantat wurde einem adulten, gesunden Ziegenbock eingesetzt, um eine vorübergehende Unfruchtbarkeit und eine Verringerung des Sexualverhaltens zu erreichen. Das Implantat wurde im Spätherbst eingesetzt. In den folgenden 6 Wochen wurde keine signifikante Veränderung der Hodengröße beobachtet. Auch die endokrine Funktion des Hodens, die durch Stimulation mit humanem Choriongonadotropin untersucht wurde, war nach 6 Wochen im Vergleich zur Ausgangsuntersuchung unverändert. Die histologische Untersuchung ergab eine erhaltene Spermatogenese.

Zusammenfassend lässt sich sagen, dass die Anwendung eines GnRH-Analogon-Implantats beim erwachsenen Ziegenbock keinen Einfluss auf die untersuchten Parameter – und damit wahrscheinlich auch nicht auf seine Fruchtbarkeit – hat.
