Here's an interesting article about how pregnancy reduces the risk factors for some medical conditions.
To be clear, pregnancy elevates some risk factors as well (e.g. deep vein thrombosis), but often these are conditions are multicausal (e.g. poor nutrition, poor exercise, smoking) and when you eliminate the other causes, any alleged negative pregnancy effect disappears.
On the other hand, just by googling "pregnancy protective effect" in about 10 minutes I found articles examining the beneficial effect of pregnancy in preventing breast and uterine cancer, alleviating multiple sclerosis, and stengthening the immune response; somebody (!) ought to do a survey of the literature and put together a comprehensive study on this!
Not that teenages commonly make decisions based on statistical analysis. (Sigh.) They are easily manipulated by the abortion profiteers. And by the junk-sex culture. There are so many avenues we have to pursue to help our young people (and not just the young ones!) recover their right minds.
Your comments are very helpful. It is a crime that Planned Parenthood and the entire abortion profiteering industry misleads our youth and women of all ages. Thanks again for all you do in defense of the unborn.
