JangoBio announced today that it has created organoids that emulate the production of ovarian and testicular hormones.

According to a release, JangoBio’s innovation has the capacity to regenerate and replace hormone-producing tissues and reverse the natural decline of sex hormones that occurs with age.

“The development of hormone-producing organoids paves the way for use in humans and animals,” JangoBio CEO Craig Atwood said in a statement. “JangoBio is rapidly moving toward testing of our organoid products in animal models.”

JangoBio said treatments will be administered by veterinary clinics in companion animals. The next phase of development will introduce organoid-hormone therapies in human clinical trials.
