Spermatozoal characteristics from fresh and frozen donor semen and their correlation with fertility outcome after intrauterine insemination

Predictive value of the hemizona assay for pregnancy outcome in patients undergoing controlled ovarian hyperstimulation with intrauterine insemination

“…Probably due to equipment expense, there are a limited number of studies assessing the predictive value of sperm motility parameters measured by CASA (computer-aided sperm analysis) on IUI treatment. Marshburn et al (27) investigated the correlation between sperm parameters determined by CASA and fertility outcome after IUI. Although there was no correlation between average path velocity and outcome, other velocity parameters were found to be highly predictive.…”

“…Categories of sperm function tests that have been studied in the clinical setting include the sperm-zona pellucida binding assays, the induced-acrosome reaction tests, and the assessment of motion parameters by computerized methods (25,26). However, only a handful of studies have addressed the role of such sperm function tests on the outcome of IUI (27)(28)(29).…”

Enrichment of motile spermatozoa from cattle semen samples by microfluidics method

“…Motility estimation is a crucial step in evaluating male fertility, and can be considered a functional test because of its relationship with the energy status of mammalian sperm (Lauria et al 1998, Quintero-Moreno et al 2004. Although motility and kinetic parameters alone cannot be considered as reliable markers for the fertilizing ability of a given ejaculate (Holt et al 1985, Marshburn et al 1992, Barratt et al 1993, Krause 1995, Macleod and Irvine 1995, Holt et al 1997, spermatozoa with low movement are unlikely to reach the oviduct, studies have proved that more is the progressive motility of spermatozoa, higher is the chance of pregnancy (Muiño et al 2008). Over the last few decades, computer assisted semen analysis (CASA) has emerged to make an objective and repeatable analysis of sperm motion as a measure of fertility assessment and quality assurance of semen for artificial insemination (Mortimer 1997).…”

Bull Semen Obtained on Beef Farms by Electroejaculation: Sperm Quality in the First Two Hours of Storing with Different Extenders and Holding Temperatures

“…On the other hand, only spermatozoa with good, progressive motility and a high amplitude of lateral head displacement are able to penetrate oestrous cervical mucus [76][77][78] and some studies have shown a positive correlation among total number of motile sperm, VCL and fecundity [53]. VCL alone may also predict fertility [79] and bulls characterized with higher field fertility displayed lower VSL, STR and LIN [80]. Moreover, it has been shown that ALH is higher in high-fertility bulls compared to low fertility bulls, and consistent with this observation LIN, STR, WOB and VSL were lower in high fertility versus low-fertility sires [81].…”
