✦ Synopsis

The possible role of a brain hormone in oogenesis of Poecilobdella viridis has been investigated by brain extirpation and brain extract injections during non-reproductive (November to January) and reproductive (March to May) periods . Brain extirpation during the non-reproductive period ceased maturation of the ovary . It is inferred that brain secretion bears possibly a gonadotropic principle which governs and regulates the oogenesis during the annual reproductive cycle .
