The Egg-Freezing Startup That's Raising Eyebrows—And Questions

When Free Becomes Complicated

Cofertility's mission sounds noble: help young women preserve their fertility for free. But the catch? You give half your eggs to intended parents. It's a model that's sparked debate about ethics, medical risks, and commercialization in reproductive health.

"The best time to freeze your eggs is when you can least afford it," says Cofertility CEO Lauren Makler, echoing the company's mantra.

The startup has gained traction among young women—especially those with strong academic or career ambitions—who may not be planning to have children immediately. But as I've dug deeper into how Cofertility operates, what started as an empowering move is raising more questions than answers.

Behind the Scam: A Closer Look at Cofertility's Model

The core of Cofertility's approach lies in its egg-sharing program called Split. Donors participate in one or two cycles of hormonal stimulation and egg retrieval, with their eggs divided between themselves and intended parents. The company fronts the cost of medical care and then sells the donated eggs to families in need.

This is not a new concept globally—egg sharing has been used in other countries—but it's rarely commercialized at scale in the U.S. Cofertility's business model, however, makes it more accessible for donors who might otherwise be unable to afford fertility treatments.

A Case Study: Sue's Journey

I met Sue, a 24-year-old from Chongqing, China, who applied to Cofertility after learning about the company online. She was drawn by its promise of free egg freezing—just one catch: she would need to give up half her eggs.

Her experience illustrates both the appeal and the concerns around the model. Initially, she was excited by how much Cofertility emphasized empowerment and personal control over reproductive choices. But as she progressed through the process, things began to feel off. Her member advocate's communication grew more intense and less professional—too effusive for a clinical relationship.

Sue had her first egg retrieval in September 2025, retrieving 26 mature eggs. She was then asked to schedule another cycle just months later, despite being in recovery from the first. That pressure, combined with what she perceived as a lack of support, made her question the company's intentions.

The Medical Risks Are Real

While Cofertility touts egg freezing as a low-risk procedure, experts point to significant health risks that can arise from repeated stimulation and retrieval. One major concern is ovarian hyperstimulation syndrome (OHSS), which can occur when hormonal treatments overstimulate the ovaries. In severe cases, it may require hospitalization.

Additionally, the egg-sharing model means donors are giving up a portion of their potential fertility. The success rate for using frozen eggs to conceive is low, and splitting cycles reduces those odds further. As reproductive endocrinologist Eve Feinberg explains, "You don't know if your best shot lies in the portion you kept."

Is This Fair?

On paper, Cofertility's approach aims for fairness by offering all donors the same treatment regardless of background or compensation. But this is only part of the story. The financial incentives and emotional manipulation involved raise serious ethical questions.

One donor, Mona, found herself matched with a couple who had already started medical procedures. When her health situation changed due to medication use, the company's handling was less than transparent—creating confusion and potential harm.

Ethical Concerns

The industry around reproductive services has long been criticized for its role in commodifying human biology. Cofertility positions itself as different by avoiding cash payments to donors, but experts argue that the service still represents a form of compensation—medical care instead of money.

Moreover, some of the profiles on Cofertility's website include extensive personal data, including family medical history, psychological assessments, and genetic traits. This information can be used for profiling by intended parents, potentially creating a new kind of discrimination within the fertility market.

Legal and Security Implications

Sue's investigation revealed that Cofertility's branding bore striking similarities to another site—My Asian Donor—which is linked to China. While Cofertility denies any connection, the resemblance raises concerns about data sharing and national security.

In her investigation, Sue also uncovered how donors are essentially treated as dual clients: part donor, part service provider. This dual identity creates a complex web of responsibilities and expectations that often aren't clearly defined.

What Comes Next?

As Cofertility continues to grow, it faces scrutiny not only from its own users but also from regulatory bodies and medical professionals. The question remains: how do we ensure that innovations in reproductive health serve everyone fairly and ethically?

The model Cofertility has pioneered might seem innovative—but its implications are far-reaching. It forces us to confront fundamental questions about autonomy, profit, and the future of human reproduction.
