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.
