Catherine Kieu, 50, of Garden Grove, was convicted in April of torture and aggravated mayhem for drugging her husband, cutting off his penis and throwing it into a garbage disposal in 2011.
Prosecutors said at Friday's sentencing Kieu and her husband, whose name was not reported, got into an argument over having a house guest. They said she spiked his dinner with Ambien, causing him to fall asleep, and when he woke up he was tied to the couple's bed frame, the Los Angeles Times reported.
Kieu cut off his penis and put it in the garbage disposal before calling 911 to report her husband was bleeding.
Kieu's public defender alleged her husband had sexually and physically abused her and she suffered mental health issues stemming from being sexually abused as a child in Vietnam.
Kieu's now ex-husband, 60, gave a statement at Friday's sentencing hearing, CNN reported.
"The convicted [person] viciously deprived me of part of my life and identity," the victim told the court. "Then, as is routine in cases of violence that involve something sexual, the victim must endure, at the hands of the defense, a second attack. This was a cruel and calculated violation of a person's body and mind. I now struggle with what is before me. She has torn off my identity as a man. She has caused doubt in my belief in good. She has betrayed my trust in people."
