In her latest film, The Switch, the 41-year-old actress plays a single woman who uses a sperm donor to get pregnant.
"Women are realising it more and more - knowing that they don't have to settle with a man just to have that child," Aniston said.
"Times have changed and what is amazing is that we do have so many options these days, as opposed to our parents' days when you can't have children because you have waited too long.
"The point of the movie is: what is it that defines a family? It isn't necessarily the traditional mother, father, two children and a dog named Spot.
"Love is love and family is what is around you and who is in your immediate sphere. That is what I love about this movie. It is saying it is not the traditional sort of stereotype of what we have been taught as a society of what family is."
Since divorcing Brad Pitt in 2005, the public has been fixated by Aniston's single status.
Asked if she still hoped to become a mother, the Friends actress replied: "Yeah, I have said it years before and I still say it today." But she laughed off a question about whether she would resort to the "turkey baster" method like Kassie, her character in the film.
"I don't have plans on that, no," she said.
Aniston was speaking at a press conference in Los Angeles to promote The Switch, which co-stars Jason Bateman.
