C. elegans hermaphrodite and male anatomy. (A) Adult hermaphrodites have two gonad arms. The distal region of each arm contains germline stem cells that differentiate to enter meiosis and then move through the gonad as they progress through meiosis, forming oocytes in the proximal region of the gonad. Oocytes are then fertilized in the spermatheca, where the sperm are stored, triggering completion of the meiotic divisions and the beginning of the mitotic divisions of the embryo. (B) Males only contain sperm, and can mate with hermaphrodites.
