According to a committee of the American College of Obstetricians and Gynaecologists, supra cervical hysterectomy, which leaves the cervix intact, does not appear to have any clear benefits over a total hysterectomy, which removes the cervix as well as the uterus, in women with non-cancerous disease and should not be recommended as a superior technique.
They have said that current research does not show significant improvements in post surgical outcomes for supra cervical hysterectomy when compared with hysterectomies that remove both the uterus and the cervix. Women who choose the supra cervical procedure are also at an increased risk for cervical cancer and will continue to need smear tests and may also need further surgery if there are problems.
However, this does not take into account the many, anecdotal accounts which report an increased loss of sensation during orgasm when the cervix is removed. Removal of the cervix also shortens and may tighten the vagina, which may also make sex painful or difficult. You can read more at: http://www.medicalnewstoday.com/articles/87480.php
