The cocktail party at the trendy Crosby Street Hotel in SoHo could have been a networking event for a hip New York investment bank or publishing house—a swarm of young women in their late 20s and 30s, mostly in business attire. But the attendees weren’t thinking about their careers. They were thinking about their ovaries. The event was hosted by a company called EggBanxx, and the women had come to drink free wine and learn about egg freezing, something their hosts were promoting as a way to stop the biological clock so they can have their babies later, whenever they damn well please.
