Fascinating and based article from Scientific American on why it will be difficult to conceive babies in space and carry a pregnancy successfully. I didn't know that International Space Station astronauts lose that much bone density from microgravity during their stay. For an adult in his or her thirties or forties, that might be too much mineral to get back, even with ideal health and reconditioning regimens after getting home. Women with osteoporosis have prescription drugs they can take to slow down this type of mineral loss, do we even know how those work in microgravity?
