When U.S. Representative Alexandria Ocasio-Cortez publicly shared her decision to freeze her eggs, 32-year-old Lorenza Zebell received a text message from a friend featuring a screenshot of the announcement alongside the note, “All the cool kids are doing it.”
At that moment, Zebell was just a few days into her recovery from the exact same procedure—a path she chose after watching her older sister face difficulties trying to conceive.
“I know that I want to have kids one day,” Zebell explained, noting that she simply hadn’t reached a point in her career or relationship where starting a family felt practical.
Between 2014 and 2021, the volume of American women opting to freeze their eggs quadrupled. However, statistics show that only about 5% have actually returned to use them.
What started out as experimental science in the 1980s has grown significantly over the last decade and a half, turning into a mainstream choice for individuals striving to coordinate health, career milestones, and romantic partnerships with future family planning.
Even so, high price tags and unpredictable success rates remain major barriers for many who might otherwise consider the process.
Who Makes an Ideal Candidate?
Medical professionals generally agree that women between the ages of 27 and 36, as well as those facing serious health diagnoses early in life, stand to gain the most from elective fertility preservation.
Conditions like endometriosis, certain autoimmune disorders, and aggressive cancer treatments can compromise ovarian tissue and egg reserves, making proactive freezing a reliable safety net for future family-building.
What is the Financial Investment?
Fertility specialists estimate that a single retrieval cycle runs around $10,000, though costs fluctuate depending on geographic location. On top of that, long-term storage fees add another $500 to $1,000 to the annual bill.
Because standard health insurance typically classifies non-medical egg freezing as elective, patients usually have to cover the expenses out of pocket. While a handful of major corporations—including Google—include fertility perks in their compensation packages, this kind of corporate coverage is far from standard practice.
For Zebell, the decision was a no-brainer because her employer, a manufacturing firm, offered up to $20,000 in fertility benefits.
Her first round yielded six eggs—fewer than the target of nine she had hoped for—prompting her to schedule a second cycle that will likely exhaust her entire $20,000 allotment.
Why Does Age Matter?
The overall efficacy of frozen eggs largely hinges on how old a woman was when they were harvested.
Every person assigned female at birth is equipped with a finite supply of eggs that diminishes over time, with numbers dropping naturally through every ovulation cycle.
While genetics and underlying health conditions play a part, younger women generally possess a larger quantity of eggs, which translates to higher odds of successful fertilization, healthy embryo development, and eventual pregnancy.
Furthermore, egg quality degrades alongside age. Older eggs carry a significantly higher risk of chromosomal abnormalities, which can trigger fertilization roadblocks, miscarriages, or congenital conditions.
Because the sharpest decline in quality egg supply typically occurs between ages 35 and 40, reproductive experts point to the late twenties and early thirties as the optimal window for the procedure.
Fortunately, uterine tissue does not age at the same rate as the ovaries, meaning women can still carry healthy pregnancies well into their 40s and early 50s using younger, preserved eggs—though advanced maternal age still carries separate health risks.
How and When Are Eggs Harvested?

The journey kicks off with initial consultations, extensive paperwork, and diagnostic testing to evaluate hormone levels and ovarian reserves.
As the patient’s menstrual cycle begins, she starts a regimen of daily, at-home hormonal self-injections designed to stimulate the ovaries so multiple eggs mature simultaneously. This phase generally lasts between eight and twelve days.
Throughout this window, doctors track follicle development through routine transvaginal ultrasounds and blood tests to measure hormone fluctuations, adjusting medications on the fly as needed.
Zebell recalled that the constant appointments, combined with the hormonal shifts, left her feeling utterly drained and unusually emotional.
“It really took over my life for a while,” she said. “I did not have a social life really, because I was exhausted.”
Once the eggs reach the desired level of maturity, a final trigger shot prompts their readiness for extraction. Roughly 36 hours later, the patient undergoes a quick, 30-minute outpatient procedure under light IV sedation. Guided by ultrasound imaging, a fertility specialist uses a specialized needle to gently pass through the vaginal wall to collect the mature eggs from the ovaries.
Reflecting on the operation itself, Zebell noted, “You just go to sleep and then you wake up.”
Dr. Kutluk Oktay, a Yale University professor and fertility preservation specialist, emphasizes that the procedure is generally very safe.
What Does the Freezing Process Involve?
Once gathered, the eggs undergo a rapid-freezing technique called vitrification—a standard practice adopted across clinics over the last decade or so—which involves immersion in liquid nitrogen to drop temperatures down to a staggering -196 degrees Celsius.
“We typically retrieve anywhere from five to 15 eggs on average, depending on the patient’s age,” notes Dr. Paula Amato, a reproductive endocrinologist at Oregon Health and Science University.
Specialists cannot determine whether an individual retrieved egg carries chromosomal flaws simply by looking at it under a microscope. Comprehensive genetic testing only becomes possible once the eggs are thawed and successfully fertilized with sperm down the road.
“You put them in the freezer and you hope for the best,” explains retired reproductive endocrinologist Dr. Nicole Noyes. “That’s why you want a good number of eggs.”
What is the Recovery Period Like?
Post-procedure side effects frequently involve abdominal cramping and bloating that can linger for up to a week. Zebell admitted she was somewhat caught off guard by the physical discomfort.
Because the ovaries temporarily swell due to hormone stimulation and egg growth, fluid retention shifts abruptly after retrieval. While these mild markers of ovarian hyperstimulation syndrome typically resolve independently, severe cases can occasionally necessitate a hospital visit.
Zebell ended up taking a few days off work to manage the intense cramping and swelling. Similarly, Ocasio-Cortez documented her own post-retrieval discomfort online, noting that she relied on over-the-counter pain relievers like Tylenol and ibuprofen to stay comfortable.
What Are the Odds of a Live Birth?
While the duration spent inside a storage tank has no negative impact on egg quality, a large percentage of women never end up using their frozen samples. Some conceive naturally, others find success through standard IVF using fresh eggs, and some ultimately decide against having children.
When the time comes to use them, the eggs are thawed, paired with sperm, and cultured as embryos in a laboratory dish for several days. Not every specimen survives the thaw; one study indicated that roughly half of thawed eggs transform into viable, mature embryos ready for uterine transfer.
Ultimately, the probability of bringing home a baby relies heavily on two major factors: the patient’s age when the eggs were collected and the total quantity successfully stored. To help navigate this, numerous clinics provide digital forecasting tools and calculators online.
For patients who complete the freezing process before turning 35, available metrics indicate potential success rates reaching up to 80%.
“There are no guarantees,” Amato points out, “but even if ultimately it’s not successful or the eggs aren’t used, most women derive some psychological benefit from having done something proactively.”
For Zebell, crossing the finish line brought a profound sense of relief. Even though the journey had its grueling moments, the pressure on her timeline has eased.
