Sperm release from the oviduct reservoir
… sperm bind to the epithelial cells of the oviduct isthmus to form a sperm reservoir. This sperm reservoir regulates sperm capacitation, reduces polyspermy and prolongs fertile lifespan. It has been proposed that oviduct glycans interact with sperm, which leads to the formation of sperm …

Role of the oviduct environment in sperm storage
… a select number of sperm populate the porcine oviduct. These sperm are stored until the time of ovulation. Sperm storage in the oviduct extends sperm lifespan, maintains their motility, and extends their fertility. This allows for a modest desynchronization of insemination and ovulation. …

Characteristics of sperm binding to the mouse oviduct
… characteristics of sperm binding to the oviduct. The study was conducted using the translucent mouse oviduct ex vivo. The specificity of sperm binding was determined using the isthmus, ampulla, and trachea (n = 4). The results showed no difference in binding between isthmus and trachea (P …

Role of transient receptor potential channels in mammalian oviduct and uterine epithelia
… homeostasis in epithelial tissue lining the oviduct and uterus which are key players in early reproductive events, being involved in gamete transport, sperm capacitation and providing the micro-environment for the gametes and early embryo. Calcium transport across epithelial cells is either …

Morphology and Albumen Secretion of the Avian Oviduct as Controlled by Sex Hormones
Made available in DSpace on 2014-12-05T22:10:14Z (GMT). No. of bitstreams: 1 0005221.pdf: 16874693 bytes, checksum: fcc70ef34d0618141d7299b0b6103914 (MD5) Previous issue date: 1953

A study of the factors controlling embryo transport in the oviduct of the mouse.
The time course of tubal transport through the oviduct of the mouse has been examined in some detail. It comprises a multi-factorial system, consisting of ciliary activity, fluid elaboration and muscular contractility, alterations in which may adversely affect fertility. This study has examined …

Investigation of the role of smooth muscle function in egg transport in the mouse oviduct.
The time course of egg transport along the mouse oviduct is important for successful implantation to occur. It is generally accepted that variations in the innate contractile activity of the oviduct musculature regulate the rate of egg transport, but the controlling mechanism behind these changes …

Purification and identification of sulfated Lewis X binding proteins in boar sperm
… sperm can be held in the isthmus region of the oviduct forming a reservoir. There is evidence that formation of the oviduct sperm reservoir is mediated, at least partially, by sperm recognition of carbohydrate structures present on the oviduct epithelium. In pigs, previous studies have proposed …

Dietary intervention with whole flaxseed or vitamin D has beneficial effects on leiomyomas in the oviduct of the laying hen
… as polyps on the smooth muscle layer of the oviduct with increasing abundance as hens age and have the same histological and molecular markers as human uterine fibroids including desmin, smooth muscle actin, increased collagen, and steroid hormone receptors. Two studies were conducted to …

TREK-1 confers differential effects on contractile dynamics in myometrium and the oviduct, indicating a unique role in endometriosis and labor
… the TREK-1 agonist ML335. It was determined that oviducts incubated in IL-6 had a decreased contractile response after washout compared to oviducts which were not exposed to IL-6, and both groups had a similar level of contractility relative to control when exposed to ML335. TREK-1 protein …

Regulation of boar sperm function by the oviduct – formation of a sperm reservoir, modulation of Ca 2+ influx, and release from storage
… reproductive tract is transported to the lower oviduct (isthmus) to form a functional sperm reservoir. The sperm reservoir extends sperm lifespan, prevents polyspermic fertilization, and is implicated in the regulation of capacitation. Once capacitated, a small number of sperm is released from …

Challenge studies in chickens to evaluate the efficacy of commercial Newcastle disease vaccines against the strains of Newcastle disease virus prevalent in South Africa since 2002
… the distribution pattern of viral antigen in the oviduct of the hens. The second study also compared the efficacy of cloacal and ocular routes of vaccination. The first study did not detect any statistically significant difference in protection offered by the vaccine against the GPMV strain in …

Microfluidic platforms to evaluate the effects of drugs on fertility and proteins on cancer progression – a focus on cisplatin, alpha-smooth muscle actin, and glial cell line-derived neurotrophic factor
… designed and fabricated to seed and grow bovine oviduct epithelial cells, to measure changes in the cilia beating frequencies (CBFs), when those cells are exposed to cisplatin using an oviduct-on-chip platform. The transparent membrane assembled in this device facilitates observational studies of …

The combinative effect of soluble suLeA glycan and specialized bovine semen extender, FSRD4+, on bull sperm quality
… we also tested the effect on longevity by adding oviduct glycans to medium and extender. Before fertilization and while bound to the oviduct, sperm become quiescent and have prolonged viability and maintained motility. Additionally, sperm undergo capacitation to reach final maturation. …
