Studies on the duration of ovum transport by the human oviduct. III. Time interval between the luteinizing hormone peak and recovery of ova by transcervical flushing of the uterus in normal women.

摘要: Abstract This article deals with attempts to time the onset and duration of ovum's sojoum in endometrial cavity women. Recovery ovum from uterus was attempted by means transcervical flushing 48 216 hours after luteinizing hormone (LH) peak plasma. A single or repetitive flushings done at 24-hour intervals same cycle were performed different subjects. With both modalities, adverse effects mild few. Of 132 76 subjects, 90 considered be technically adequate point view recovering over 50% volume. Twenty ova recovered. Technically timing LH accomplished 39 cycles. In this group, 13 recovered between 96 168 peak. The highest yield per obtained 120 an average 37% a range 25% 50%. Limitations technique are discussed. Some uncertainties persist which prevent drawing definitive conclusions about how soon egg enters uterine cavity, long it stays there, what is extent individual variation. However, recovery rates various times ovulation agree previous data derived transfundal indicate that usually transferred retained there for several days.
