IVF Mix-Up Uncovered Decades Later Through DNA Test

In 2025, Sasha Szafranski embarked on a journey to research her father's Eastern European heritage, submitting a DNA sample to Ancestry.com. Her results unveiled an unexpected and deeply personal truth: a close match with Elizabeth, a stranger from her hometown, identified as her maternal aunt. This initial connection led to further communication and a startling revelation. Upon learning Sasha was an IVF twin, Elizabeth inquired if the twins were conceived via IVF. Sasha confirmed this, which then brought to light that Elizabeth's sister had also undergone IVF and had a daughter who was identified as Sasha's full biological sibling by Ancestry.com.

Investigative Findings Confirm Mistake

Subsequent investigation confirmed that both families had utilized Royal North Shore Hospital in Sydney for IVF treatment in 1995. Further DNA testing at accredited laboratories, involving Sasha, her twin sister, the woman identified as their biological sister, and her parents, solidified the findings.

The results conclusively showed a 99.9% relative chance that the other couple were Sasha and her twin sister's biological parents.

The families believe that two embryos from Sasha's biological parents were mistakenly transferred to Penny Szafranski, Sasha's mother, within a 24-hour window following fertilization in 1995.

Background of IVF Treatment

Penny Szafranski had a history of multiple unsuccessful rounds of IVF at Royal North Shore Hospital. In 1995, she decided on one final attempt. Her egg retrieval took place at Hunters Hill Private Hospital, with the subsequent embryo transfer occurring at Royal North Shore Hospital. Two embryos were transferred, which resulted in Penny's pregnancy with fraternal twin daughters. Penny raised her daughters alone after her marriage ended, eventually moving to Coffs Harbour when they were five years old.

Profound Emotional Impact and New Connections

Sasha reported feeling different throughout her childhood, a sentiment that resonated deeply following the discovery. The revelation of her biological heritage, particularly seeing a photo of her biological sister and noting their strong resemblance, caused significant emotional distress. When Sasha and her twin informed Penny, Penny initially reacted with disbelief but later expressed deep upset over the loss of her daughters' biological identity. Sasha's partner, Jai Milsome, also observed the striking resemblance.

Sasha subsequently met her biological parents in Coffs Harbour, surprisingly residing only 15 minutes from them. She described a strong, yet complex, initial connection with her biological family.

Search for Accountability and Reform

Both families have engaged legal representation to investigate responsibility for the error. Royal North Shore Hospital's fertility unit was transferred to North Shore A.R.T in August 1994, prior to the incident. North Shore A.R.T was later acquired by Virtus Health. However, Virtus Health denied responsibility, stating the incident predated its establishment.

Crucially, Penny's original embryos from her 1995 treatment remain unaccounted for.

Sasha, due to personal distress, withdrew from the litigation process. Instead, she advocates for systemic reform and comprehensive support services for families affected by similar errors. Federal Health Minister Mark Butler stated he became aware of the error through media reports and expressed concerns about a lack of transparency and accountability within the IVF sector. The Reproductive Technology Accreditation Committee (RTAC) reported being informed of the mix-up earlier this year, adding that the RNSHRC was unaware of the error during its operation.

Ongoing Adjustment and Family Bonds

Sasha stated her relationship with Penny remains unchanged, emphasizing Penny's irreplaceable role as her mother. She acknowledges the difficulty and individuality of each family member's journey in processing these revelations. Sasha has found a profound connection with her biological family, including a shared passion for surfing, which she believes provides a unique insight into her childhood feelings of being different.
