A case report of delayed delivery of 99 days in a triplet pregnancy is presented. A triplet pregnancy in a single uterus resulted from Pergonal stimulation of ovulation. At 23.5 weeks' gestation, the first triplet delivered after spontaneous rupture of membranes. Ninety-nine days later, the remaining two fetuses were delivered, the second one stillborn after intrauterine death at 37 weeks of gestation, and the third fetus a normal viable female consistent with 37.5 weeks' gestation. This is the longest interval of delayed delivery discovered from a literature review, and the only such instance of triplet pregnancy in a single uterus.
