title: [Endocrine capacity of blastocysts in mammals. I. Progesterone biosynthesis and metabolism].
abstract: In order that blastocyst implantation occurs in mammals, it is required the synthesis and secretion of several substances including steroid hormones by the preimplanted embryo. In this paper, we analyze the embryo endocrine capacity for biosynthesis and secretion of progesterone and several progestines.
