A lawsuit filed this week alleges that the only full-time gynecologist at the California Institution for Women in Chino subjected women to abusive procedures and unwanted exams, with other medical staff and prison officials accused of failing to take action despite red flags.

Women at the California Institution for Women reported sexually abusive and “sadistic” behavior during gynecology exams despite the risk of retaliation, including potential transfer to another prison, solitary confinement and possible disciplinary actions, according to the lawsuit.
