Here's a thing about Wonder Woman that's totally odd, but also really, really cool: she hails from an island solely populated by women. We know that these women of the island of Themyscira are born and grow up in their close society, because we've already seen trailers which show Diana (aka Wonder Woman) as a young girl. But can the Amazons of Themyscira have babies? I mean, we all know how babies are made in our world, and yet the crucial part of the baby-making equation — having a man involved to offer up his biological goods — isn't present on Themyscira. So how does that whole thing work there?
Turns out, the Amazons were designed in the image of their creators, a host of Greeks goddesses who were absolute badasses. Much like other humans and creatures created at the hands of the Greek gods, the Amazons were created for the purpose of delivering peace and justice across the world on behalf of the gods. According to the good old DC Comics wiki about the Amazons, these female warriors were created by Greek goddesses Hestia, Aphrodite, Demeter, Athena, and Artemis. This supernatural race of women were created from the souls of women who had died at the hands of men, with one soul set aside for a special purpose (I'll give you three guesses who that special soul belongs to).
The implication behind these godly origins is that the Amazons have an incredibly long lifespan, so there is no need to procreate because there is no biological impetus to do so. It is known that Diana is the youngest Amazon in this ethnically diverse group of women, but it is still unclear whether she can have children or whether she would even want to have children. As far as the DCEU is concerned, there is no indication Diana was or will be a mother, regardless of whether she can have kids or not. I suppose, on that note, all that matters is that Wonder Woman is a sex-positive superhero; that's really all we need be concerned about regarding her sex and reproductive life.
It will be interesting to see if the topic of children ever gets mentioned in the DCEU as far in relation to the Amazons. Considering their epic origins, it would definitely be of interest to see how future generations come to be.
