Gravity and Embryo Development

Purpose of Review The precise impact that gravity, or the lack of gravity, plays in the key phases of mammalian reproduction remains a mystery. Humans and all other known living species have adapted to the effects of gravity on Earth. Only recently has the study of gravitational biology become truly possible. As humans spend increasingly longer periods of time in space, the effect of minimal gravity (microgravity) on mammalian reproduction must be addressed.
