I am pro-choice and pro-IVF. Although I have some concerns about some aspects of either practice, I firmly believe that any reproductive issues an individual female may have, should be a matter between her and her health care professionals.
The law should give full autonomy over her own body to the female, with strict regulations regarding embryos located outside of her body.
On the matter of "wants" or the right to be a parent, I look at the issue from an evolutionary biology point of view.
The purpose of every single living being on this planet is the preservation of their species - to survive, to find a mate, to reproduce and to raise copies of themselves that in turn survive and find a mate and reproduce and raise copies of themselves that in turn etc etc ad infinitum.
This biological imperative also applies to humans qua animals. Of course, uniquely among animals, as a species we have learned to adapt. For individual humans, the involuntary and unconscious drive to reproduce can be overruled by other needs, for some permanently, for others only temporarily. While we are not slaves to our biology, the urge to reproduce, when it hits, is far more powerful than an idle "want" or an entitled lifestyle choice.
No, there is no right to parenthood, but what there is, is a drive. A drive that can be so strong, so overpowering even, that it engulfs your entire being, subsumes your relationship and dominates your life.
While it is not felt by all humans, for those who do feel it, it is no more voluntary than our need to breathe.
I've felt it. A cancer scare when I was 24 switched it on without warning. I went from worrying about falling pregnant to worrying that I couldn't fall pregnant in the course of a day. I then changed my entire life plan and set everything in motion to have a baby while I still could. And I did.
But when we decided to have another, I went through secondary infertility issues. Then the loss of a much longed for baby, the stress of genetic testing of DH and me to find out if we carried and had passed on a possible genetic malformation to our firstborn. Followed by the stress of TTC after a loss (while still having the infertility issues), pregnancy after a loss, then developed a pregnancy complication that can kill your baby in the womb without warning (nicely exacerbated by being treated like a stupid, hysterical woman by the male consultant). Leading to an early induction and some (relatively mild) early baby issues.
I didn't put myself and my family through all of that because of an idle "want". I wasn't acting on a mere wish or a whim. It's hard to describe but I needed to try to have this baby just as much as I needed to eat or sleep.
I take no offence at those who oppose IVF or abortion, but I do wish they could oppose it on an individual level. By not availing themselves of those choices, while allowing those of us who do wish to make them the right to do so.
