Pinworm
The pinworm, also known as the threadworm is a parasitic worm. It is a common intestinal parasite, especially in humans.
Sexual reproduction for pinworms is often a self-destructive act. Male pinworms forcibly inject genetic material into females, which is an act known as traumatic insemination, which can cause physical damage to the females' bodies. Adult males are smaller than females, and they usually die after a forcible mating session. It takes about a month for the recently deceased male's genetic material to circulate through the female's body and fertilize the thousands of eggs contained within. Females then deposit their eggs on the host's perianal glands after emerging onto the surface skin, and they die shortly afterward.
