The hermaphroditic worm is considered to be a specialized form of self-fertile female, as its soma is female. The hermaphroditic germline produces male gametes first, and lays eggs through its uterus after internal fertilization. Hermaphrodites produce all their sperm in the L4 stage (150 sperm cells per gonadal arm) and then produce only oocytes. The hermaphroditic gonad acts as an ovotestis with sperm cells being stored in the same area of the gonad as the oocytes until th… Web02. jun 2016. · C. elegansis a self-fertilizing hermaphrodite that lives for a few weeks when cultured at 20 °C, and it was first used as a model organism to study aging in the …
