- Annelid - Wikipedia
Earthworms store their partners' sperm in spermathecae ("sperm stores") and then the clitellum produces a cocoon that collects ova from the ovaries and then sperm from the spermathecae Fertilization and development of earthworm eggs takes place in the cocoon Leeches' eggs are fertilized in the ovaries, and then transferred to the cocoon

- Clitellum - Wikipedia
In earthworms, the clitellum can only be seen when the worm is sexually mature It may be white, orange-red or reddish-brown in colour Earthworms are ready to mate when their clitellum is orange [2] In leeches, the clitellum appears during mating season, where it is used for both sexual reproduction and the secretion of a cocoon for the eggs [4]
- Clitellata - Wikipedia
During reproduction, the clitellum secretes a yolk (albumen) and a proteinaceous sheath which hardens The worm then creeps out backward from the coat and deposits either fertilized zygotes or both ovae and sperm into the coat, which is then packed into a cocoon
