It is well known that the luteal function in the @entity1 with @entity4089 is much suppressed by high level of serum @entity4090 . Present study was performed to investigate whether the luteal function in the @entity1 with transient or occulted @entity4089 was affected by the transient increase of serum @entity4090 level. The circadian changes of serum FSH, LH, @entity4090 , @entity1815 , @entity53 and @entity1420 levels were examined in seven cases of the transient or occulted @entity4089 whose BBT charts showed biphasic patterns. Serum @entity4090 levels of these @entity1 were less than 25 ng/ml at daytime and more than 150 ng/ml at 30 minutes after the administration of 500 micrograms of @entity1218 . Blood samplings were taken every two hours through an intravenous indwelling catheter without any disturbances. All of the @entity1 had their breakfast at 7 to 8, lunch at 11 to 12 and dinner at 17 to 18 o'clock and slept from 22 until 6 in the next morning. Serum FSH, LH, @entity4090 , @entity1815 , @entity53 and @entity1420 levels were determined by RIA and the circadian changes of these hormones were analysed. Then, 5 mg of @entity2847 was administered every day to these @entity1 for more than 30 days and the duration of the luteal phase and the mid-luteal serum @entity53 and @entity1420 levels for the indicators of the luteal function were examined before and after the administration of @entity2847 . The circadian changes of serum @entity4090 levels in the @entity1 showed significant increase during both daytime and night compared to those of the control (p less than 0.005, p less than 0.005).(ABSTRACT TRUNCATED AT 250 WORDS)
