luteinized unruptured follicle syndrome: a reevaluation

ABSTRACT

59 women with unexplained infertility [study group], and 15 cases presenting AIH [control group], formed the material for this work. Estrogen, progesterone, and luteinizing hormone were measured from days 12-17 of cycle, along with ultrasound folliculometry, for biochemical and sonographic evidences of ovulation, respectively. The low incidence of luteinized unrupted follicle [LUF] in the study group, and the conception of one of the LUF cases in the control group, makes further assessment of the real role of LUF in unexplained infertility necessary. Furthermore, ultrasonography demonstrated ability to substitute, invasive and expensive hormone assays, for a assessment of the functional integrity of the ovulatory process
