Temperature changes suggestive of hot flushes in rhesus monkeys: preliminary observations.

To determine if changes in skin temperature known to accompany hot flushes in women also occur in monkeys, temperature recordings were made in three adult rhesus monkeys before and after ovariectomy and in one postmenopausal female. Increases occurred especially on the skin of the ear pinna, with greater frequency following ovariectomy. This animal model may be suitable to investigate the mechanism which causes hot flushes in women.
