Does Abortion Cause Preterm Delivery?


According to the March of Dimes, 380,000 babies are born prematurely each year! Why?

They are many causes but no one disputes that abortion is linked to future preterm deliveries. Not even abortionists. Surgical abortion increases relative risk of future preterm birth by 52% and low birth weight by 41%.1 The risk increases with each additional abortion.

One of the reasons for this is that surgical abortions require the forcible opening of the cervix in order to extract the baby, causing “cervical incompetence.” This permanently damages the cervix, weakening it so that carrying a pregnancy to full-term becomes difficult or impossible.

Another reason for preterm deliveries is found in a 2007 medical journal study, noting that abortion causes a thinning of the uterine lining, making it difficult to sustain pregnancy.2

Many women seriously considering abortion want to have children in the future. Is it important that they know abortion may damage their chances of a healthy future pregnancy?3
