It does reduce blood flow to the ovaries as well, so does result in menopause in approximately 15-20% of
women over 45. Another very new
procedure is the MRI-guided ultrasonic ablation of fibroids--although there is not a lot of data on this procedure--theoretically it would be less likely to cause a reduction in blood supply to the ovaries.
Also, myomectomies can be performed laparoscopically in many instances--so no need for removal of ovaries, or big incisions, and no need for hormones.
