Yes and no. Old studies showed that very clearly, but modern research takes many more factors into account (culture, age, social status are just as important as gender.) It's actually completely meaningless to say that either gender interrupts more, because it can always be either true or not. And in any case it is always without fail pointless - even dangerous - to generalise what we think we know about one gender as a group, to one person. If an individual interrupts people a lot, it is not caused by their gender. It is possibly influenced by their gender, culture, family situation, age, native language and social status in combinqtion. But it is still a choice to do it or not.
