The female body, when lacking the nutrients needed to run the body properly, shuts down the female reproductive system first. Libido shuts down; the menstrual cycle quits; she does not want sex--unless it is for either the affirmation or degradation of her body-- nor is she able to birth a child. All of her body's resources go purely to the continuation of her survival.
After the female body recovers from her starvation, there is a distinct possibility that she will never be able to get pregnant or carry a pregnancy to term. Even if she is able to, this process will likely be far more difficult and unlikely than it would typically be.
These facts directly dispute the oft repeated claim that a woman's biological purpose is to reproduce. When given the choice between survival and reproduction, the female body chooses, time and time again, survival. Reproduction is not prioritized in the slightest; in fact, it is often the very first bodily function to be shut down--literally deemed the least important part of a woman's body. And this choice of survival--the prioritization of the heart, the lungs, the bones--over the reproductive system is not even to the purpose of allowing a woman to reproduce later in life; no, the reproductive system is at the very least damaged, if not debilitated for the rest of the woman's life.
If the female body, as so many claim, was biologically "meant" to first and foremost reproduce, perhaps it would choose to increase libido and prioritize the reproductive system in order to let the woman birth a descendant before ultimately dying. This is not what the female body does. The female body itself declares that its own life, not that of which it could create, is the most important, that the female body, alive, is worthy even if it never passes its genes on. The female body declares that it is not alive only to further humanity, to reproduce and then die, but instead to live; to live its own life, following the desires of the woman in command of it and no one else.
The next time someone tries to insist that women are biologically meant for nothing more than populating the earth in the cage of kitchens and bedrooms, remind them of the hundreds of thousands of women living their lives, making scientific discoveries, creating art, and leading nations who survived an attempt of making themselves small, and now take up space, for years, completely unable to reproduce.
