Intrauterine fetal response to hypergravity by reduction of plasma prolactin levels in the rat.
Rats were conceived after adaptation to 3.14 g. Maternal and fetal plasma prolactin levels were reduced on day 22 of gestation in the rats exposed to hypergravity. The fact that fetuses in utero respond in the same way as their mothers indicates that they too are sensitive to hypergravity and that the bouyant condition of the fetus does not interfere with such external stimulus.
