A quintuplet gestation after ovulation induction with clomiphene and HCG is described. This is the first quintuplet birth reported in Israel. The pregnancy was associated with ovarian hyperstimulation syndrome, toxemia of pregnancy, and pruritus gravidarum. Diagnosis and management of these cases pose a special problem for the obstetrician and neonatologist. The problem of multiple pregnancies and their control in the treatment of infertility with ovulation-inducing drugs is discussed.
