Abstract
Mice injected daily with 50 μg of melatonin, 12 hr after lights on, for 18 weeks, underwent gonadal regression after 4–7 weeks and reproductive recrudescence after 15 weeks. Most treated animals molted to a winter pelt after 9–11 weeks of injections, and 2 of the 10 mice experienced bouts of daily torpor after 14 weeks.
