Lisbet Binet, the woman who gave birth to a set of quadruplets this weekend, had not been treated with fertility drugs, according to her doctor Claudia Rincon Tatis. The physician who attended her during her final three weeks, Dr. Jose Garrido Calderon had spoken to the press about the effects of fertility medication on multiple births. The multiple conception resulted from natural sexual relations with her husband. The young mother, who is just 22, was treated at the Centro Oriental de Ginecologia, Obstetricia y Especialidades. The four babies’ condition has improved, with two still on ventilators and two doing just fine. All four are being fed with their mother’s milk. First Lady Margarita Cedeno de Fernandez has promised to ask her husband to donate a house for the children to grow up in.
