title: Uteroglobin and related biochemical changes in the reproductive tract during early pregnancy in the rabbit.
abstract: The macromolecular secretion products of the rabbit uterus are described. The biochemical and biological properties of uteroglobin are considered, and its synthesis and secretion in various endocrinological conditions are described. The release of uteroglobin from the endometrial epithelium is stimulated by progestagens such as progesterone and its synthetic analogues, although its synthesis has not yet been shown to be entirely dependent on progesterone. The biological function of uteroglobin is obscure. Several approaches to this long-standing probelm are discussed, including the passage of uteroglobin into the blastocyst. It is suggested that interference with the passage of uterine components into the blastocyst may inhibit implantation and provide a means of contraception.
