Wrongful Pregnancy: Failed Sterilization Claims

A vasectomy or tubal ligation that fails due to genuine medical negligence is a real malpractice claim — but it is a claim with an unusually narrow ceiling in most states, precisely because the “injury” it produces is, in the eyes of most courts, a healthy child.

Quick answer: Wrongful pregnancy (or wrongful conception) arises from a negligently performed sterilization procedure or a contraception error that results in an unplanned pregnancy — distinct from wrongful birth, which involves a missed diagnosis of a disability. In most states, damages are limited to the pregnancy and delivery itself — medical costs, pain and suffering, lost wages, the cost of the failed procedure and a corrective one — not the ongoing cost of raising the child, on the reasoning that a healthy child’s value offsets that burden. New Mexico is a notable exception, allowing recovery of the full cost of raising the child to adulthood.

What Triggers This Claim, and How It Differs From Wrongful Birth

Wrongful pregnancy (sometimes called wrongful conception) arises when a sterilization procedure — a vasectomy, a tubal ligation — or a contraception error, such as a pharmacy misfilling a prescription, is performed or handled negligently and fails, resulting in an unplanned pregnancy. This is a genuinely different fact pattern from our companion guide to wrongful birth and wrongful life claims: wrongful birth involves a missed prenatal diagnosis of an already-existing pregnancy’s disability; wrongful pregnancy involves a failed attempt to prevent conception in the first place, and the resulting child is typically healthy. That single difference — disabled child versus healthy child — is exactly why the two claims are valued under completely different damages rules.

The Majority Rule: Damages Limited to the Pregnancy Itself

Most states that recognize this claim limit recoverable damages to costs directly tied to the pregnancy and delivery:

• The cost of the failed sterilization procedure or the contraception error itself
• Medical expenses for the pregnancy and delivery
• Pain and suffering associated with the pregnancy
• Lost wages during the pregnancy and recovery
• The cost of a subsequent, successful sterilization procedure, where pursued

What most states specifically deny is recovery for the ongoing cost of raising the resulting child to adulthood. The reasoning: a healthy child’s inherent value to the family offsets what would otherwise be a purely compensable financial burden — sometimes described as a “benefits” limitation on damages, distinguishing this claim sharply from a wrongful birth claim, where the extraordinary costs of a genuine disability are recoverable precisely because no comparable “offsetting benefit” reasoning is thought to apply to a disability’s extraordinary costs.

New Mexico: A Genuine, Significant Outlier

In Lovelace Medical Center v. Mendez, 805 P.2d 603 (N.M. 1991), the New Mexico Supreme Court broke from the majority rule directly. The case involved a negligently performed sterilization, compounded by the provider’s failure to notify the patient that the procedure had failed, resulting in a healthy child. The court held that the parents could recover the full cost of raising that child to adulthood — expressly rejecting the “benefits” reasoning most other states apply. This makes New Mexico one of the few states where the same underlying facts produce a dramatically larger recovery than they would almost anywhere else in the country, and it is worth knowing directly rather than assuming a “typical” damages figure applies nationally.

When Non-Disclosure Makes the Underlying Case Stronger

A recurring, aggravating fact pattern: a provider performs a follow-up test after a sterilization procedure — a semen analysis after a vasectomy, for instance — that shows the procedure failed, and does not tell the patient. Where that happens, some courts treat the separate failure to disclose as compounding the underlying negligence, since the patient lost a real opportunity to take precautions, seek a repeat procedure, or otherwise avoid the resulting pregnancy entirely. Records showing what a provider actually knew, and when, can meaningfully strengthen a claim beyond what the initial procedure’s negligence alone would show.

Practical Steps

1. Obtain the complete medical records of the sterilization procedure or the prescription at issue, including any documented follow-up testing and its results.
2. Determine whether the procedure’s failure was ever disclosed to you, and when, since undisclosed knowledge of a failure can strengthen the underlying claim.
3. Document the pregnancy, delivery and any subsequent corrective procedure completely, since these are the costs most states will actually allow you to recover.
4. Confirm your specific state’s damages rule before forming any expectation of value — the difference between the majority rule and New Mexico’s approach is not a minor variation.
5. Consult an attorney experienced in this specific claim type, given how differently it is valued from an ordinary malpractice claim and from the related wrongful birth claim.
