Early conceptual loss in subfertile patients.
The incidence of early conceptual loss was studied in 27 subfertile women by measuring their serum and urine hCG levels in the luteal phase. Eleven patients eventually had clinically confirmed pregnancies, nine of whom had had significant hCG elevations in previous menstrual cycles. In the remaining 16 patients, who have so far failed to achieve a clinical pregnancy, only three had had elevated hCG results. Thus 'apparent' early conceptual loss in non-pregnancy cycles was found to be more often associated with the fertile group of patients.
