Research overview: electroejaculation for semen collection in felids

Collecting semen from nondomestic cats usually requires electroejaculation under anesthesia, a standardized technique that allows evaluation and banking of sperm. This overview surveys how electroejaculation is performed in felids, the quality and volume of ejaculates obtained, and how the method supports semen analysis, cryopreservation, and artificial insemination. It reviews species differences in semen traits, including the high prevalence of abnormal sperm in cheetahs and inbred lions, and the importance of consistent protocols for comparing samples. The review connects semen collection to genome resource banking and reproductive assessment. Understanding electroejaculation is fundamental to felid reproductive science, since it provides the gametes needed for both research and assisted reproduction across many species.
