Zargon syndrome (the most common term in US English), Zargon's syndrome (standard in the rest of the English-speaking world), is a reproductive disorder caused by superfertility. It is named after Zargon, the
American who single handedly fertilized four children in just
two pregnancies. The disorder is characterized as having multiple sets of
twins in a short period of time. Few males can claim to be stricken with the disorder.
