Original title was "Same-sex mice have babies" which is the title of the article. I think current title is perfectly fine, and is actually what's going on.

> Does sexual reproduction formally require sexual intercourse? At this point I'm out of my depth. :p

Yes, but not necessarily sex (e.g. pollination), but it's exclusively sex for mammals. We do not know of any other method for mammal reproduction other than sex. This puts mammals in a very weird spot since they're the only known group in animals that have not been observed to reproduce non-sexually.
