There’s an itemized list of their delegated powers and the 10th amendment says that if it’s not on that list then it belongs to the states and the people. Health care is not on the list. Neither is education. They are state items.
There is nothing in the Constitution that gives the federal government the power to regulate or fund the treatment of pregnancy, contraception, or to treat SDI, STI, TDS, etcetera, etcetera, etc.
