A study was done of women in the US, India and China about the responses to having their ovarian tubes tied. The study discovered that relatively more American women displayed anxiety emotionally, that more Indian women showed symptoms of hysteria, and that Chinese women were more likely to feel that they had a backache, their stomachs hurt, they were unable to sleep, or they felt weak and exhausted.
曾經有人研究美國、印度與中國婦女結紮輸卵管後的反應發現：美國婦女有較多焦燥不安等情緒上的表現；印度婦女呈現較多歇斯底里的症狀；中國婦女則老是覺得自己腰酸背痛、腸胃不舒服、失眠、混身無力等。
