IVF Embryo Mix-Up: 7 Shocking Facts About the Florida Case

An IVF embryo mix-up in Florida became one of the most closely watched fertility stories of the past year, and it raises questions that go far beyond one family’s heartbreak. Here’s the full, factual story, the details many people missed, and an honest look at the financial and cultural dimensions of what happened.

What Actually Happened in This IVF Embryo Mix-Up

Tiffany Score and Steven Mills underwent IVF at the Fertility Center of Orlando, a clinic in Longwood, Florida, and had three embryos placed in cryogenic storage there. In March 2025, the clinic transferred an embryo into Score’s uterus. In December 2025, Score gave birth to a daughter the couple named Shea.

Score and Mills are both white. According to their lawsuit, they pursued genetic testing after noticing that Shea “displayed the physical appearance of a racially non-Caucasian child.” The results confirmed the IVF embryo mix-up: Shea was 100% South Asian and not genetically related to either of them. In January, the couple sued the clinic, IVF Life, Inc. (doing business as the Fertility Center of Orlando), and its lead reproductive endocrinologist, Dr. Milton McNichol.

The Search for Shea’s Biological Parents

Rather than treating this privately, Score and Mills pushed for accountability that affected far more than their own case. Their lawsuit demanded the clinic notify every patient who had embryos in storage during the relevant window, so those families could determine whether they, too, might be affected. The clinic reportedly identified roughly 16 sets of potential biological parents whose egg retrieval and transfer dates aligned with Score’s, before narrowing to one South Asian couple. By April, that couple, identified only as “Patient 004” to protect their anonymity, was confirmed through DNA testing as Shea’s genetic parents, according to NBC News’ ongoing coverage of the case.

IVF Embryo Mix-Up Facts Many People Missed

This wasn’t the clinic’s only lawsuit. Separately, in March, another woman filed suit against the same clinic alleging she had been allowed to serve as a surrogate for a family member despite a documented history of severe mental illness that she said prevented her from understanding what she was agreeing to.

The clinic closed abruptly, and questions remain about why. The Fertility Center of Orlando announced its closure this spring, stating only that the decision came “after thoughtful consideration.” Score and Mills’ attorney publicly questioned the timing, noting concern that the closure could be “an attempt to dodge responsibility” rather than a routine business transition.

Score and Mills’ own embryos are still unaccounted for. Even after Shea’s biological parents were identified, the couple’s remaining stored embryos have not been fully resolved. One embryo labeled with Score’s name required transfer to a new facility for independent genetic testing, since the original clinic’s recordkeeping was no longer considered reliable.

Custody wasn’t settled in court, it was settled privately. In June, court filings confirmed that Score and Mills reached a confidential custody agreement directly with Shea’s biological parents following the IVF embryo mix-up, avoiding a public custody battle entirely. Score and Mills remain Shea’s permanent legal custodial parents, and both families have stated their intention to build an ongoing relationship of friendship and trust, while protecting Shea’s privacy.

The Financial Piece of This IVF Embryo Mix-Up Nobody Talks About Enough

An IVF embryo mix-up like this exposes a financial reality the fertility industry rarely discusses openly: individual clinics carry enormous responsibility with comparatively little external oversight. According to the CDC’s Assisted Reproductive Technology program, fertility clinics report outcome data annually, but embryo storage and handling practices themselves are governed more by individual clinic protocol and state law than by uniform federal regulation. When errors happen, patients often bear the emotional and financial burden of pursuing accountability through costly civil litigation rather than through a straightforward regulatory process.

The clinic’s closure amid “legal and financial problems” left affected families in a uniquely difficult position: pursuing malpractice claims against an entity that may not have the assets to fully compensate them, while simultaneously trying to recover embryos and records from a business that no longer exists in its original form. This is a financial vulnerability that extends well beyond Score and Mills. Every patient who had embryos stored at that clinic now faces uncertainty about their own genetic material, with limited recourse if something went wrong for them too.

The Cultural Piece of This IVF Embryo Mix-Up, Handled With Care

Shea is being raised by white parents while being genetically South Asian, a reality that will shape her identity in ways her parents are still learning to navigate. To their credit, Score and Mills have publicly emphasized their intention to build a real, ongoing relationship with Shea’s biological parents rather than erasing that connection, which many experts in transracial adoption and donor-conceived identity consider an important factor in a child’s long-term wellbeing and sense of self.

This case also surfaces a broader cultural conversation about genetic identity, race, and family that intersects with, but is distinct from, the more familiar conversations around transracial adoption. Shea did not lose her biological family through choice or circumstance in the way adopted children often do. Her situation exists at an unusual intersection: a birth mother who carried and delivered her, and separate biological parents who share no gestational connection to her at all. There is little existing research or precedent specifically addressing children in this exact situation, since, as one attorney involved in the case noted, embryo mix-ups resulting in a birth are known to have happened to only a handful of families.

There’s another layer worth naming honestly: Shea’s biological parents chose to remain anonymous even during the DNA confirmation process, and that choice deserves real consideration, not judgment. Depending on their cultural or community background, disclosing that they used IVF at all, let alone that their genetic child was born to and raised by another family, may carry a level of stigma or privacy risk that outsiders don’t fully appreciate. Infertility and assisted reproduction remain deeply private, sometimes shameful topics in many cultural and religious communities, and going public could expose “Patient 004” to scrutiny within their own family or community that has nothing to do with anything they did wrong.

There’s also a practical reality underneath the private agreement: a prolonged custody fight requires significant financial resources, and there’s no guarantee both families were positioned equally to sustain one. Litigation of this kind, expert witnesses, attorneys, potential appeals, can run into hundreds of thousands of dollars over time. It’s entirely possible that Shea’s biological parents’ decision to pursue a private agreement rather than a court battle for custody was shaped not only by what they believed was best for Shea, but also by the financial and emotional cost of fighting two years or more in family court against parents who had already publicly committed to a legal defense. A private agreement doesn’t necessarily mean both sides felt equally free to choose it.

Why Tiffany Giving Birth to Shea Complicates Everything

One detail is easy to lose in the broader story: Tiffany Score carried and gave birth to Shea. This is not a surrogacy case, and it is not a straightforward embryo-swap-before-implantation story either. Score’s body sustained this pregnancy for nine months, and under Florida law, as in most states, the woman who gives birth is presumptively the child’s legal mother, regardless of genetic connection. That legal reality is a significant reason Score and Mills had strong legal footing from the outset, separate entirely from the emotional bond they described.

This gestational connection complicates any simple “genetics versus environment” framing of the case. Shea’s biological parents contributed genetic material, but Score’s body did the physical work of pregnancy and childbirth, work that carries its own recognized biological and legal weight. Any honest discussion of what’s fair here has to hold both truths simultaneously: genetic parenthood matters, and gestational parenthood matters, and this case is one of the rare instances where those two things were forcibly separated by someone else’s error, not by either family’s choice.

What’s Actually Best for the Child? An Honest, Non-Biased Look

There is no clean, universally agreed-upon answer here, and it’s worth resisting the urge to pretend there is one.

The case for stability with Score and Mills: Attachment research generally supports the idea that the earliest bond a newborn forms, through pregnancy, birth, and the first months of life, carries real developmental weight. Score and Mills argued exactly this in their lawsuit, describing an “intensely strong emotional bond” that began in pregnancy. Removing an infant from her only known caregivers after months of bonding carries documented psychological risk, and the fact that Score carried and delivered Shea herself adds a biological dimension to that bond that a typical embryo-mix-up-before-implantation scenario wouldn’t involve.

The case for prioritizing genetic connection: Others in the identity and adoption research space argue that a child’s long-term sense of self, particularly around race, ethnicity, and extended family history, benefits significantly from access to biological family, and that decisions made in a child’s earliest months shouldn’t necessarily determine what’s best for her at five, fifteen, or twenty-five.

What actually happened here threads a middle path. Rather than a court forcing an either/or outcome, both families chose a private agreement that kept Shea with her birth mother while deliberately preserving a relationship with her biological parents. Many child welfare advocates would consider this closer to a best-of-both-worlds outcome than either extreme for a case like this IVF embryo mix-up, stability of primary caregiving, combined with ongoing access to biological identity and extended family, though the confidential nature of the agreement means the public may never know its full terms.

Ultimately, what’s best for any individual child in this kind of situation depends on details that outsiders, however well-intentioned, aren’t positioned to fully judge from the outside. What can be said fairly is that both families appear to have prioritized Shea’s stability and long-term wellbeing over a public legal fight, which is not nothing, and it may offer a template for how future IVF embryo mix-up cases could be handled with more compassion than litigation alone allows.
