Experiments on binding 125I-LH and 125I-HCG by the human luteal tissue of early pregnancy showed no certain presence of receptors. On the other hand, studies performed with cyclic luteal tissue demonstrated the presence of high specificity, significant affinity receptors. Possible interpretations with reference to the physiological increase in HCG and/or to the characteristics of extrauterine pregnancy are discussed.
