“…Our measurements were carried out under semi-in vivo conditions where the CBF was measured immediately in the media; this did not affect the CBF. There are several elaborate studies on ciliary activities in human fallopian tubes (Critoph & Dennis 1977;Weström et al 1977;Yamaoka 1987;Lyons et al 2002). However, the availability of human tissues is limited.…”

“…Error bars show the standard deviation in CBF for valid measurements at each time point for each oviduct. increases in the human isthmus and ampulla after ovulation (Critoph & Dennis 1977) and in the infundibular region of the tube during the secretory phase (Lyons et al 2002).…”

“…1977), whereas another group reported a significant CBF differences between different anatomical sites, but no clear significance at different stages of the menstrual cycle (Yamaoka 1987). However, it has been reported that CBF significantly increases in the human isthmus and ampulla after ovulation (Critoph & Dennis 1977) and in the infundibular region of the tube during the secretory phase (Lyons et al. 2002).…”

Analysis of ciliary beat frequency and ovum transport ability in the mouse oviduct

The oviduct is important in reproduction where fertilization occurs, and the fertilized eggs are conveyed to the uterus. Multi-ciliated cells of the oviductal epithelium and muscle contractions are believed to generate this unidirectional flow. Although there are many studies in human oviducts, there are few reports on mouse oviductal ciliary movements where we can dissect underlying genetic programs. To study ciliary movements in the mouse oviduct, we exposed the ovary-side of the oviduct (infundibulum) longitudinally and recorded the ciliary beatings in a hanging drop preparation. We calculated the ciliary beat frequency (CBF) by automated image analysis and found that the average CBF was 10.9 ± 3.3 and 8.5 ± 2.5 Hz (±standard deviation) during the diestrus and estrus stages, respectively. Mapping of the CBF to multiple locations in the epithelium showed that the cilia beat regularly at a local level, but have a range of frequencies within the entire plane. We also observed ova with cumulus cells were transported to the uterus side by the opened oviduct at the diestrus and estrus stages. These results suggest that the ciliated cells of the infundibulum can generate unidirectional flows and are able to deliver ova by their ciliary activities despite their discordance in beating periodicity.

“…The Fallopian tube undergoes cyclical changes under the influence of oestrogen and progesterone, during the normal menstrual cycle (49). Receptors for oestrogen and progesterone have been identified within the Fallopian tube epithelium, and the expression of these receptors varies according to the stage of the menstrual cycle (50).…”

Background.There is no immunohistochemical study to show luteinizing hormone receptor (LHR), estrogen receptor (ER) and progesterone receptor (PR) in the pregnant Fallopian tubes (FT).Objective. To study LHR, ER, PR expression in FT containing an ectopic pregnancy (EP) and during the menstrual phase.Design. Thirty FT were obtained from women diagnosed with EP and twenty FT collected by hysterectomy performed for benign diseases not affecting the tubes were included in this study. Assessment of immunohistochemical expression staining LHR, ER, PR in epithelium, smooth muscle cell and blood vessel endothelium in FT containing an EP and during the different phases of menstrual cycle.Results. In ectopic pregnancy group we found LHR expression in epithelium in 30 cases, muscle cell in 28 cases, and endothelium in 9 cases in FT. In menstrual cycle group we noted LHR expression in FT in epithelium in all cases, muscle cell in 4 cases.Conclusion. There is a significant difference in the proportions of the existence of LH receptor immunostaining in the muscle cells for ectopic pregnancy group as compared to the menstrual cycle groups (p < 0.001). Our findings may suggest that the women who have increased LH receptors on muscle cells in Fallopian tubes are at increased risk for having external pregnancy.

“…However, none of these methods has been objectively validated, and some of them have been shown to be inaccurate [Naitoh and Kaneko, 19731. It has been shown, for instance, that in both rabbits and humans the frequency of ciliary beat varies at different times during the sexual cycle and in different segments of the oviduct [Borell, Nilsson, and Westman, 1957;Critoph and Dennis, 1977;Westrom et al, 19771. Whether these variations are due to direct hormonal or neurohormonal control on the ciliated cells or to changes in mucus cannot be ascertained from these studies.…”
