Sperm cells from a 42-year-old gorilla could bring the promise of new life thanks to the work of a wildlife charity.

Jock, a silverback western lowland gorilla who spent the majority of his life at Bristol Zoo in Clifton died in February after his relocation to the zoo’s new site near Cribbs Causeway.

Following his death, wildlife conservation charity Nature’s SAFE worked with the Bristol Zoological Society to preserve Jock’s bodily tissues, testicular tissue, and semen.

“Although Jock has passed, it is of real comfort to know that, in a sense, part of him lives on in our tanks,” said Terri Hill, vice chair of the charity.
