Abstract
Invitro incubation of primate embryos in the presence of gonadotrophin releasor hormone (GnRH) results in enhanced chorionic gonadotrophin production associated with increased survival and attachment of the embryos. Treatment of invitro fertilized embryos with GnRH can be used to improve implantation. Agonists of GnRH reduce attachment competence of embryos and are thereby useful as post-fertilization contraceptives.
