Answer
Marie-Thérèse never had children. She married her cousin, Louis XIV of France, in 1660. The couple had been married for 23 years, but Marie-Thérèse was unable to conceive a child. There are many theories about why Marie-Thérèse was unable to conceive a child, including that she was infertile, that Louis XIV was sterile, or that there was a medical problem with the couple.
