The female pinworms lay eggs in the folds of skin around the anus. The presence of these eggs often causes itching and irritation. When a person scratches the affected area, the pinworm eggs are transferred to the fingers. The eggs can survive for several hours on your hands.
The adult pinworms are white and measure less than one half inch long, with the diameter of a strand of thread. These tiny roundworms are quite complex. Like us, they have mouths, throats, and gastrointestinal tracts. Like us they have nervous systems. The females have a vagina, a uterus, and ovaries.
