Abstract
The last 10 years have seen a revolution in our understanding of the structure and functions of chorionic gonadotrophin (CG). Until the early seventies it was thought to be a glycoprotein hormone restricted to pregnancy in primates. It was known to be secreted by the trophoblast and assumed to be a major component of the luteotrophic stimulus that supports the corpus luteum of primates until the luteoplacental shift is completed1–3. While this role in early pregnancy, backed by a great deal of circumstantial evidence, is still accepted, we are now fairly certain that the hormone is restricted neither to pregnancy nor to primates.
