SAN FRANCISCO — A state court judge has sided with the ex-husband in an emotional legal battle over the fate of the divorced couple’s frozen embryos. On Thursday the judge issued an order allowing the embryos to be destroyed.

Mimi Lee and Stephen Findley are bound by an agreement they signed directing the fertility clinic to “thaw and discard” their embryos in the event of a divorce, San Francisco Judge Anne-Christine Massullo wrote in a tentative ruling Wednesday. Massullo rejected Lee’s heartfelt pleas to save the embryos that Lee, in her mid-40s, considers her last chance for biological children.
