As hermaphrodites, leeches have both male and female sex organs. Like the earthworms they also have a clitellum, a region of thickened skin which is only obvious during the reproductive period. Mating involves the intertwining of bodies where each deposits sperm in the others' clitellar area. Rhyncobdellids have no penis but produce sharp packages of sperm which are forced through the body wall.

Why are leeches used medically in the reattachment of severed toes and fingers?
After a reattachment surgery, patients can suffer from "venous congestion". This means that blood is being pumped to the area, but cannot be pumped out because the blood vessels in the new digit are too small and delicate to be surgically attached. The leeches are used to drain this trapped blood until the body reconnects the severed blood vessels and can drain the blood on its own.
