title: Preliminary results on the scanning electron microscopic structure of infertile human cervical mucus.
abstract: Interesting data on infertile human membranous mucus compared with infertile filamentous mucus have emerged from previous studies using scanning electron microscopy (SEM). The aim of this study was to obtain more information about the infertility of membranous mucus being independent of ovarian hormone stimulus. All different types of mucus, progressively secreted during the menstrual cycle by endocervical muciparous cells, were collected from the cervical canal of a fertile woman with a long menstrual cycle and specifically with a long infertile preovulatory period. The most significant results concern the identification of the cycle phase characterized by the presence of membranous mucus alone, i.e. the infertile preovulatory phase and the hormonal bases of membranous mucus infertility. The conclusion is reached that each ovarian hormone pattern stimulates the secretion of a specific type of mucus during the menstrual cycle.
