Questions to assess whether the participant has had a hysterectomy or has had her ovaries removed.


The purpose of these questions is to assess the occurrence of hysterectomies with or without ovary removal. This measure identifies the impact of surgery on a woman’s hormonal system and will be important in any gene/environmental studies of hormones or hormonal-related diseases.
