Would not fertilize. She's not fat and an adequate face, so she will have no problems finding men to have sex with her, even at her advanced age. Because she's childless, she'd also be attractive to similarly aged childless men and some older men with grown children.
I also do not understand what is so deeply satisfying about a corporate job as a sales representative for a maker of medical devices. Giving up having kids when you want them for a meaningless job sounds like faulty decision making to me.
She has also had a long window available to have children. At 43, she's been able to have kids for 27 years. She finished college as a 22 year old in 2001 and had decent corporate jobs since then (per her LinkedIn), so she's been in at least an adequate place to handle having children for 21 years. It is amazing that she's been reasonably attractive and an adult for 25 years and hasn't managed to find a husband and have babies.
