ftmax is right, removal of ovaries would be oophorectomy. However, you may still have a cervix. There are variations on hysterectomy procedures, some include removal of the cervix. If you don't have a uterus, removing the cervix might still be something to consider, in terms of long-term issues with being on T (cervical cancer in the worst case, or just not needing pap smears anymore).
He's also right that oophorectomy means, ideally, some form of HRT for the rest of your life. Definitely not something to rush into.
