Because it is generally accepted that a high percentage of poorly motile or immotile sperm will adversely affect male fertility, analysis of sperm motility is a central part of the evaluation of male fertility. In spite of its importance to fertility, poor sperm motility remains only a description of a pathology whose underlying cause is typically poorly understood. The present review is designed to bring the clinician up to date with the most current understanding of the mechanisms that regulate sperm motility and to raise questions about how aberrations in these mechanisms could be the underlying causes of this pathology.

BACKGROUND Sperm screening is an essential step in in vitro fertilization (IVF) procedures. The swim-up method, an assay for sperm motility, is used clinically to select the ideal sperm for subsequent manipulation. However, additional parameters, including acrosome reaction capability, chemotaxis, and thermotaxis, are also important indicators of mammalian sperm health. To monitor both sperm motility and chemotaxis simultaneously during sperm screening, we designed and constructed a microdevice comprising a straight channel connected with a bibranch channel that mimics the mammalian female reproductive tract. METHODS The width and length of the straight channel were optimized to select the motile sperms. We selectively cultured cumulus cells in the bibranch channel to generate a chemoattractant-forming chemical gradient. Sperm chemotaxis was represented by the ratio of the sperm swimming toward different branches. RESULTS The percentage of motile sperms improved from 58.5% (3.8%) to 82.6% (2.9%) by a straight channel 7 mm in length and 1 mm in width. About 10% of sperms were found to be chemotactically responsive in our experiment, which is consistent with previous studies. CONCLUSIONS For the first time, we achieved the combined evaluation of both sperm motility and chemotaxis. The motile and chemotactically responsive sperms can easily be enriched on a lab-on-a-chip device to improve IVF outcome.

This study was aimed to determine the effect of the dilution ratio of sperm with optimal NaCl and fructose on the motility of the catfish, Clarias sp., spermatozoa, fertility and hatchability of eggs. Catfish used in this study consisted of one parent pairs (male and female weight of 1000 grams weight of 1500 g). NaCl and fructose solution were diluted with aquabidest. The observation was conducted on the motility of spermatozoa, fertility and hatchability of eggs. The experimental design used completely randomized design (CRD). Dilution ratio is 1: 0, 1, 20, 1: 40, 1; 60, 1: 80, and 1: 100 with replicated 3 times. Observations were carried out soon after the sperm mixed with diluents. Fertility occurred 12 hours after fertilization. Egg hatchability was observed after fertilization. The results showed that the ratio of dilution gave significant effect on the sperm motility, fertility and hatchability of the eggs. This research found that the dilution ratio 1: 60 was the best treatment with the average sperm motility of 96. 66%, fertility of 71, 66 5% and egg hatchability of 70%.
