The relevant estimates are 59% and 66%.

In fact most people who engage in abuse are themselves often abuse victims, usually as children.

Note that this isn't meant to excuse anyone's behavior. Research like this is meant to help contextualize the problem and provide solutions to help mitigate it.

Another point that's important to make is that most abuse victim do not because abusers themselves. Those are two different stats ;)

My source is a book about child abuse:

Turton, J. (2007). Child abuse, gender and society. Routledge.

From page 13:

One of the most significant concerns regarding the long-term harm that may be inflicted by female sexual abusers was highlighted in some research projects concerning male sexual offenders. Groth (1979) found that sixty-six percent of the rapists in his study reported child victimization by female perpetrators. Petrovich and Templar (1984) found that fifty-nine percent of rapists in their study had been sexually abused by a female. Briere and Smiljanich's (1993) data from a self-report survey found,

among the sexually abused men who reported sexual aggression against women, 80% had been sexually abused during childhood by a female perpetrator. In other words, sexual activity during childhood with an older female strongly predicted later sexual aggression against adult women . . . childhood sexual victimization by females is a particular risk factor for later assault directed against adult female victims. (summarized in Mendel 1995, 62)

This paper quotes all three studies as well:

Another stat quoted in this study is that 44% of boys in juvenile prisons were sexually abused by women. 46% of adult men in prison for any crime have also been abused by a woman. A comparable figure for adult women in prison is 78%.

A comparison here isn't perfect because the cohort of men in prison is a bit difference than the cohort of women in prison. Due to the fact that it takes a lot more to put a woman in jail than a man. But it's an interesting statistic none the less.

There was a small discussion about the above paper here:
