title: [Echographic imaging of absence of follicular rupture. Endocrinologic aspects].
abstract: Since Jewelewicz in 1975 first described the luteinization of an unruptured follicle (LUF), clinical evidence for the importance of this syndrome has been given by various groups of investigators. Luteal phase of 14 cycles with ultrasound evidence of unruptured follicles were studied with plasmatic determination of levels of FSH, LH, prolactin, 17 B estradiol and progesterone each one day. Two groups were defined. One, with "ovulatory ranges" of progesterone, probably LUF syndrome and another, with "anovulatory levels", probably follicular cysts.
