Oxytocin coordinates the uterine contractions that are involved in giving birth, and it does that so effectively that when obstetricians want to start or speed up labor, they hook you up to an IV bag of it .

The delay in cognitive decline brought about by the drug likely amounts to just several months, but Dr. Joy Snider and some other experts say it could still meaningfully improve people’...
