Molecular basis of sperm reservoir formation in the oviduct and the effects of scrotal hyperthermia
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2027-05-01

Regulation of boar sperm function by the oviduct – formation of a sperm reservoir, modulation of Ca 2+ influx, and release from storage
… Upon insemination, a small fraction of the sperm deposited in the female 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 …

Sperm release from the oviduct reservoir
Sperm undergo capacitation while traveling through the female reproductive tract, a process including several biochemical and physiological events before fertilization. Also prior to fertilization, sperm bind to the epithelial cells of the oviduct isthmus to form a sperm reservoir. This sperm …

Characteristics of sperm binding to the mouse oviduct
A wide variety of animals store sperm between mating and ovulation. The sperm reservoir prolongs sperm lifespan and keeps sperm in a quiescent stage due to delayed capacitation and suppressed motility. The objective of this study was to determine different characteristics of sperm binding to the …

Purification and identification of sulfated Lewis X binding proteins in boar sperm
After insemination, 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 …

The combinative effect of soluble suLeA glycan and specialized bovine semen extender, FSRD4+, on bull sperm quality
… the U.S. as the preferred method to store bovine sperm due to convenience despite damage to sperm during processing and thawing. For this reason, one of our objectives was to determine if a liquid extender, FSRD4+, could extend the lifespan of sperm by days. Since longevity with minimal sperm …

Enhanced fertility estimation and novel ion channels in boar sperm
Cryopreserved boar sperm have many potential advantages when used for artificial insemination (AI), including increased time for pathogen testing and ease of semen transport. However, frozen boar sperm are seldom used for AI due to decreased pregnancy rates and litter sizes as a result of …
