[Luteinized unruptured follicle syndrome].
In a group of 109 infertile women, 180 cycles were monitored with B type ultrasound, BBT and cervical scoring. The incidence of LUF in stimulated cycles was 31.8%, significantly higher than that in spontaneous cycles (10.1%). During the follicular phase, no difference was found between the LUFS and normal ovulatory cycles as to follicular growth curve, maximal diameter of dominant follicle and the cervical scores. Therefore prediction of the LUFS is difficult. 63.6% of the LUF patients had recurrences, and high incidence of abnormality (70.6%) in their non-LUF cycles. 7 of the 14 patients with LUFS were originally diagnosed as unexplained infertility. It suggests that LUFS is of particular importance in the group of women with unexplained infertility.
