Spring Fertility, a clinic in Midtown Manhattan, looks like the place where the main characters on “Broad City” would have wound up if the millennial sitcom had done an episode about egg freezing. The waiting room has books by America’s youth poet laureate Amanda Gorman and its Instagram poet laureate Rupi Kaur. The kitchen is stocked with Spindrift. A conference room also serves as a venue for “shots nights,” less raucous than they sound, where patients inject themselves with fertility drugs communally, with encouragement from staff.

Spring’s medical director in New York, Catha Fischer, dressed in a loose blouse and a low ponytail, beamed as she showed me the phlebotomy stations and operating room, where patients are anesthetized so that a doctor can puncture their ovaries with a needle and suck out eggs for freezing. The room, Dr. Fischer noted, “looks like a Grey’s Anatomy O.R.”

There is always a market for products, from skin care to weight loss, promising to ease the angst of womanhood. Efforts to slow down the reproductive clock are no different. The business of egg extraction is thriving, among the privileged group of people who can access it.

Across Spring’s clinics nationwide, the number of egg freezing cycles undertaken last year jumped 37 percent from the year before. That surge is visible at fertility clinics around the country, according to data from the Society for Assisted Reproductive Technology. The prototypical patient also seems to be getting younger, doctors say, a change coinciding with a steady uptick in corporate benefit packages that cover fertility preservation. In 2015 just 5 percent of large employers covered egg freezing; in 2023, nearly one in five did.

Some medical technologies spread slowly, but the embrace of fertility preservation has grown at a remarkable rate. In 2015 there were about 7,600 egg freezing cycles recorded nationwide, and by 2022, that number hit 29,803, a nearly 300 percent increase.
