Estrogen formation in the early rabbit embryo.
Androgen formation (3beta-hydroxysteroid dehydrogenase activity) was detectable in the rabbit blastocyst on day 5 of gestation (before implantation); estrogen formation was first detectable on day 7. The capacity to form estrogen on the day of implantation suggests that estrogen formation in the blastocyst may play a role in the implantation process.
