The oviduct of the laying hen is an organ histologically differentiated into four areas, each with a unique function in the biosynthesis of the egg (2). It contains high concentrations of a number of unusual nucleotides, including uridine diphosphoacetylgalactosamine and uridine diphosphoacetylgalactosamine-(4?)sulfate (3). More recently, it has been observed that uridine diphosphoacetylgalacto...
The oviduct plays a vital role in ensuring successful fertilization and normal early embryonic development. The male inseminates many thousands or even millions of sperm, but this alone does not ensure that fertilization will be successful. The female tract, particularly the oviduct, provides filters that select for normal vigorously motile sperm. In conjunction with molecules in the seminal pl...
The aim of the study was to analyze the application value of three-dimensional hysterosalpingo-contrast sonography (3D-HyCoSy) in the diagnosis of oviduct obstruction. Fifty-two patients with infertility and oviduct obstruction were continuously selected and treated with 3D-HyCoSy and CLP (CLP). It was found that according to CLP diagnosis, 40 oviducts were obstructed, 30 were partially obstruc...
This study examined the effect of the presence of single or multiple embryos on the transcriptome of the bovine oviduct. In experiment 1, cyclic (nonbred, n = 6) and pregnant (artificially inseminated, n = 11) heifers were slaughtered on Day 3 after estrus, and the ampulla and isthmic regions of the oviduct ipsilateral to the corpus luteum were separately flushed. Oviductal epithelial cells fro...
Chlamydia trachomatis is the most common bacterial sexually transmitted disease in the United States and a major cause of female infertility due to infection-induced Fallopian tube scarring. Epithelial cells are likely central to host defense and pathophysiology as they are the principal cell type productively infected by C. trachomatis. We generated cloned murine oviduct epithelial cell lines ...
Using a digital videomicroscopic analysis system in the bovine, we showed that the mechanisms of transport caused by ciliary beating are distinctly different in ampulla and isthmus of the oviduct. The average particle transport speed (PTS) in the oviduct (mean, 133 microm/sec) does not differ in the cycle (metestrus) and during pregnancy after implantation, but it is locally modulated at the si...
BACKGROUND Oviducts participate in fertilization and early embryo development, and they are influenced by systemic and local circulation. Local functional interplay between ovary, oviduct and uterus is important, as deduced from the previously observed differences in hormone concentrations, presence of sperm, or patterns of motility in the oviduct after unilateral ovariectomy (UO). However, the...
Purpose: To compare effects of polarized epithelial monolayer prepared from human oviduct and uterus on mouse one and two-cell embryo development. Materials and Methods: Human oviduct and endometrial tissue was obtained from patients who had undergone total hysterectomy. The epithelial cells were isolated from tissue and cultured on extracellular matrix (ECM) Gel coated Millipore filter insert...
Background: The aim of this study was to evaluate protective effects of melatonin on uterus and fallopian tube in female mice under treatment with nicotine. Materials and Methods: Adult Female mice were divided into four groups. Group A: control animals received normal saline, group B: were injected with nicotine 40 μg/kg. Group C:were injected with melatonin, 10 μg/ night. Group D:were injecte...
