We must also look at the study closely; this was done in China. Abortions are forced upon the women, meaning a lot of stress. Pregnancy creates hormonal changes, the process is designed whereby hormones go through a series of increasing and decreasing at appropriate times, an abortion suddenly stops the process and the body must quickly readjust. Any cells that are there that may be affected will be affected. We also must add into the mix the stress that is created by forcing a woman to undergo an abortion that otherwise would want to carry the child to term. Our bodies are directly affected to stress. Put all these factors together and we can easily see why there is such an increase.
