Can a post-menopausal woman be a surrogate mother?

To be honest, I don’t know anything about menopause Mostly, I know that menopause is the female body’s way of saying, “Okay, that’s it, no more kids, no more menstruation and way less hormones,” but what I really want to know is how that effects a woman’s ability to actually give birth. I know a post-menopausal woman can’t conceive, but could she conceivably be a surrogate? If she could be a surrogate, does menopause do other things to the body that would make it that much more difficult for her to give birth? Do you know of any cases of post-menopausal surrogates?

Basically, anything you know about the subject is appreciated. I have just gotten an idea for a story and I need to know if it’s feasible or just plain bunk. Thank you!
