SC20992 - Suprynowicz v. Tohan ("The plaintiffs, Kayla Suprynowicz and Reilly Flaherty, who were strangers for most of their lives, discovered through the genetic testing company 23andMe that they are half siblings. They allege in this action that their biological father is the defendant, Narendra B. Tohan, the reproductive endocrinologist who assisted the plaintiffs' parents in the parents' efforts to conceive children. The plaintiffs claim that, in treating their parents' infertility, the defendant utilized his own sperm rather than the sperm of the men they believed to be their fathers to impregnate their mothers, causing the plaintiffs physical and emotional harm. Although the plaintiffs' causes of action were labeled in the complaint as ordinary negligence claims, the defendant moved to strike them on the ground that they were noncognizable wrongful life claims. The trial court agreed and granted the motion to strike the plaintiffs' complaint.
The dispositive issue in this appeal is whether the trial court correctly determined that the plaintiffs' negligence claims sounded in wrongful life rather than ordinary negligence. We conclude that the answer to that question is no and that our recent decision in Lynch v. State, 348 Conn. 478, 308 A.3d 1 (2024), controls the outcome. In Lynch, this court clarified that a claim arising from hospital staff's alleged negligence in using sperm infected with a virus in the course of a therapeutic donor insemination (TDI) procedure sounded in medical negligence, not wrongful life. See id., 484–87, 489–91, 505, 507. Similarly, the plaintiffs' claims in the present case are ordinary negligence claims rather than wrongful life claims because they arise from the defendant doctor's alleged negligence in using his own sperm to impregnate the plaintiffs' mothers during in vitro fertilization (IVF) procedures. Accordingly, we reverse in part the judgment of the trial court.")
