2020, Molecular and Cellular EndocrinologyCitation Excerpt :In mammals, after mating or artificial insemination, only a few spermatozoa reach the oviduct, where they bind to the luminal epithelial cells for hours to days forming the so called “functional sperm reservoir” (Hunter and Wilmut, 1984). During this storage, the interactions between the oviductal epithelial cells (OEC) and spermatozoa are believed to play an important role in sperm selection (Mburu et al., 1997; Tienthai, 2015) maintenance of sperm viability (Ellington et al., 1999) and prevention of premature capacitation (Murray and Smith, 1997) before ovulation. Then, around the time of ovulation, spermatozoa are released from the OEC and move towards the fertilization site (Coy et al., 2012).
Effect of colloid centrifugation on boar sperm quality during storage and function in in vitro fertilization
2019, TheriogenologyCitation Excerpt :Sperm quality is a term used to describe the likelihood that spermatozoa in a sample will be functional, either when used in assisted reproduction or if the male is used for natural mating. For spermatozoa to reach the oocyte, they need to move from the site of semen deposition (usually in the vagina or uterus) through the lower reproductive tract to the utero-tubule junction where they populate the sperm reservoirs [5,6]. Thus, they must possess progressive motility to avoid being lost from the female reproductive tract by backflow [7].

2016, TheriogenologyCitation Excerpt :In the pig, most spermatozoa stored in the preovulatory functional tubal sperm reservoir (e.g. the utero tubal junction and the adjacent first caudal portion of the isthmus), are seemingly immotile and depict normal ultrastructure during the long preovulation period [28,29]. These spermatozoa remain in the preovulatory functional sperm reservoir for most of the time of estrus and definitely do not readily migrate toward the infundibulum immediately after they are inseminated [29]. Moreover, far from all hereby stored spermatozoa contact the lining epithelium, an axiom proposed by others using in vitro methods (reviewed in 40) to be a prerequisite to their arrest in the preovulatory functional sperm reservoir.
Sperm selection in the female mammalian reproductive tract. Focus on the oviduct: Hypotheses, mechanisms, and new opportunities
2016, TheriogenologyCitation Excerpt :If this interpretation is correct, both the vanguard and oviductal spermatozoa should exhibit characteristics that mark them out as being “superior” to the unselected bulk populations. Ultrastructural studies of the pig oviduct in vivo support the view that the selected and membrane-bound spermatozoa possess intact plasma membranes [37,38], but it is difficult to validate this view directly from these in vivo observations. Nevertheless, a significant study by Ardón et al. [39] has shown that boar spermatozoa carrying unstable chromatin have less chance of reaching the oocytes in vivo than spermatozoa with normally stable chromatin.
