ABSTRACT Three of 24 infertile women with a short luteal phase transiently showed chorionic gonadotrophin (HCG) like immunoreactivity in serum as measured by the HCG-beta subunit radioimmunoassay. The plasma progesterone concentration was elevated above the lower normal post-ovulatory level in 2 of these women who also had elevated basal body temperature at the time HCG was detected. Positive HCG reaction coincided with the pre-ovulatory surge of luteinizing hormone (LH) in one patient, but in 2 other cases the LH concentration was low suggesting absence of LH interference. Our results suggest that some infertile women may conceive during their cycles with a short luteal phase and maintain pregnancy until HCG becomes detectable.

ABSTRACT Plasma LH and progesterone levels were measured around the time of ovulation in 16 normal menstrual cycles. No increased levels of progesterone were found before the LH peak. The maximal LH peak levels lasted for 16–20 h at which time the plasma progesterone rose to a concentration of 1 to 2 ng/ml. Following the fall in the LH concentration, there was a rapid rise in the plasma progesterone concentration, indicating the formation of a corpus luteum. The lowest basal body temperature coincided with the first significant rise in LH levels.

SUMMARY Plasma levels of luteinizing hormone (LH) in normally cyclic women during the menstrual cycle and in rats during the oestrous cycle were measured by bioassay. With the human subjects, it was possible to establish a mid-cycle peak of LH and correlate it with basal body temperature, while with the rats a peak of LH secretion was noted between 15.00 and 19.00 h on the day of pro-oestrus. The levels of LH in both groups of subjects were of the same order as those measured by other assay techniques.
