Florida Couple Sued Fertility Clinic Over Sperm Mix-Up
A Jacksonville family filed a lawsuit after DNA testing revealed a fertility clinic used incorrect sperm during IVF.
Updated on Sept. 18, 2026 in Pregnancy
A Jacksonville couple has filed a negligence lawsuit against Brown Fertility after DNA testing confirmed the father was not biologically related to their child. The discovery occurred following a newborn blood test that indicated a biological inconsistency.
Why it matters
This case highlights the emotional and legal risks inherent in assisted reproductive technology, raising questions about patient verification and clinical protocols. It also underscores why families undergoing IVF may seek clarity on clinic practices regarding embryo and sample management.
A legal filing confirmed the discrepancy between the intended biological father and the child after blood typing showed a blood-type incompatibility. The clinic performed two embryo transfers, with the second attempt resulting in a full-term pregnancy.
The players
Natalie Strong
The 36-year-old mother who underwent two rounds of in vitro fertilization.
Joshua Strong
The 53-year-old father who underwent an invasive sperm-retrieval procedure.
Brown Fertility
A Jacksonville fertility clinic currently facing a negligence lawsuit regarding its IVF procedures.
Dr. Samuel Brown

The details
The couple alleges that Brown Fertility substituted Joshua Strong's sperm with an unidentified sample during the IVF process. Joshua Strong had undergone an invasive sperm-retrieval procedure necessitated by a prior vasectomy to create seven embryos. A newborn blood test revealed the child had B-positive blood, which was biologically inconsistent given Natalie Strong has O-negative blood and Joshua Strong has A-negative blood.
Timeline

Health Landscape
This case sits within the broader regulatory environment governed by the Florida Medical Malpractice Act regarding clinical standards of care. It reflects an ongoing trend of legal challenges aimed at increasing accountability in fertility centers.
Patients undergoing IVF may consider discussing verification protocols and clinic oversight with their fertility specialists before starting procedures. Any concerns regarding biological consistency or unexpected results should be raised directly with a physician to facilitate further testing.
The takeaway
This case serves as a stark reminder of the complexities involved in IVF and the importance of verifying every stage of reproductive care. Families with concerns regarding clinical practices or biological discrepancies should speak with a physician or legal expert to discuss their specific situation.
