    IVF, good or bad
    IVF treatment in most cases is the last option for couples with infertility problems. I live in Israel, that has more fertility clinics than anywhere in the world, Israel also performs the highest number of IVF procedures per capita – almost 4,000 fertility treatments per million, in comparison to the 300 fertility treatments per million in the United Kingdom. you can get more info at www.ivfinisrael.info. The IVF procedure has nothing to do with choosing genes, but with a man and a woman desperate to get pregnant. Most couples want a child of their own and don’t want to adopt, and IVF treatment sometimes is the last chance

    correction
    Affect is a verb, effect is a noun. When you say "to finish the affect," it should probably be "to finish the effect."

    remember: they always try to trip us up w/ a Q about oxygenated/de-oxygenated vessels/arteries... once you know the drill tho, it's really easy: cuz there's ONE artery that carries de-oxygenated blood AWAY from the heart to the lungs, and one vessel that carries oxygenated blood TO the heart from the lungs.
