Abstract
The corpus luteum (CL) is an important endocrine organ in the menstrual cycle and in pregnancy. The regulation of its hormonal production has been extensively studied. The steroidogenic abilities of the CL can be rescued by human chorionic gonadotrophin (HCG) but its role in the maintenance of CL function is not clear. We will discuss the hypothesis that there are fetoplacental factors, other than HCG, that modulate CL steroidogenesis.
Key words: corpus luteum / fetoplacental factors / human chorionic gonadotrophins / pregnancy / steroidogenesis
