Currently, at least away from labs in shadowy places, it requires sperm from a man (in many cases boys considering maturity levels) and an egg form a women. We all know the traditional method of the uniting procedure. Although I could talk passionately for hours about that, I will move onto my point.
After this uniting it is the women;s body that facilitates the growth and maturity of the fetus. Without that body and foregoing the test tubes in shadowy labs,the fetus cannot survive. it is dependent on the female system.
As this being a natural thing, a women's decision whether to carry the fetus or not is an extension of this natural phenomenon. It is more connected that any outside force attempting to overpower this decision. It is the woman's body that is the vessel for the maturing fetus. It has nothing to do with society or special interests. Nothing at all.
I will further say that a healthy, unfractured mind healed form separation would likely opt to carry the fetus but that is an entirely different issue and beyond the scope of this post...for now. Forcing one against their will deepens the fracture and take our society further away from harmony and balance.
I hope this made sense.
