Gonadotrophin releasor hormone-containing composition for embryo culture and method for in vitro fertilization

摘要

In vitro incubation of primate embryos in the presence of added exogenous gonadotrophin releasor hormone (GnRH), results in enhanced chorionic gonadotrophin production associated with increased survival and attachment of the embryos. Treatment of in vitro 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.
