Can undergoing stress after embryo transfer affect the embryo?

There is controversy regarding the effect of stress on the results of assisted reproductive techniques, with studies showing a negative effect and others in which no association is seen. In any case, the negative effects could be linked to the activation of the cortisol pathway and it is not known specifically what factors could influence directly or indirectly (oocyte or implantation). There is no evidence of a direct effect at the embryonic level.
