Florida Couple Sued Fertility Clinic After DNA Mix-Up
A Jacksonville couple filed a negligence lawsuit alleging their fertility doctor used the wrong sperm during IVF.
Updated on Sept. 18, 2026 in Pregnancy
Natalie and Joshua Strong filed a negligence lawsuit against Brown Fertility and Dr. Samuel Brown after DNA testing confirmed the husband is not the biological father of their daughter. The couple discovered the discrepancy following a newborn blood test that showed a biological inconsistency between the child and the parents.
Why it matters
The lawsuit alleges that the clinic mistakenly substituted the father's sperm with that of an unidentified donor during the in vitro fertilization process. This case highlights critical concerns regarding laboratory oversight and the security of biological materials in fertility treatments.
The couple underwent two rounds of in vitro fertilization after Joshua Strong, 53, completed an invasive retrieval procedure. Natalie Strong, 36, gave birth to the child on June 5, 2025, following the second embryo transfer.
