(ish!): The management of Sydney’s Taronga Zoo has mooted “manual stimulation” of Kibabu the gorilla, in order to grab some monkey semen for artificial insemination.
“I believe it’s done in Europe”, they say (maybe they’re harking back to the days of Weimar Berlin). Zookeepers, being the ones who’d get their hands dirty (so to speak), are — understandably — not too keen.
It now looks like something called “electro-ejaculation” will be used instead… sounds painful. (Link from forteana.)
