Clarification on IUDs
After reading Donna Butler’s Feb. 17 “Your Health” column, I felt obligated to add some information and, perhaps, correct some misconceptions about IUDs.
IUDs work in two different ways. First, they make it less likely for fertilization of an egg by sperm. The second mechanism is by causing an early abortion. The Mirena IUD website states that one way it prevents pregnancy is it “makes the lining of your uterus thin.” What that means is that it prevents the uterus from developing its normal, healthy, plush lining, causing it to be inhospitable to a fertilized egg. This early embryo is unable to implant in the uterine lining, unable to live and grow and so dies, lacking the nutrients to sustain life and develop into a viable fetus, as it would have otherwise.
If one believes that life starts at conception, then this second method of the IUD prevents this life from becoming a growing fetus, in other words, causing a very early abortion.
