Abstract
Summary
Both ovaries and suprarenals were removed from 2 monkeys which were then injected with cortical extract (Swingle). Three experimental menstrual periods were then induced by injections of theelin-total doses ranging from 500 to 690 r.u. in 10 to 11% days. Latent periods of 4 to 5 days followed the last injections and then menstrual periods of 4 to 7 days. The adrenal medulla is not essential to experimental menstrual periods induced by theelin.
