Groups 1 and 2 were combined as an experimental group by averaging the chemotaxis index of group 1 and the reciprocal of the chemotaxis index of group 2. Full-term pregnancies achieved with ICSI despite high levels of sperm chromatin damage. Do human eggs attract spermatozoa? Due to the presence of high unsaturated fatty acid in its membrane and deficiency of the antioxidant in its cytoplasm 34 , sperms may be vulnerable to harmful effects of reactive oxygen species ROS which may lead to sperm DNA damages Frisco Institute for Reproductive Medicine.

Integration of Sperm Motility and Chemotaxis Screening with a Microchannel-Based Device
There are some chemical products that are stimulator for in-vitro improvements of the testicular sperm motility The mechanism of the acrosome reaction induced by ionophores differs from the physiological acrosome reaction induced by the zona pellucida The effects of different sperm preparation methods and incubation time on the sperm DNA fragmentation. The Shapiro test was used for evaluating normal distribution of data. Gradual degeneration of the testicular somatic cells after a long-term culturing may decrease the sperm motility. It accounts for between 40 to 50 percent of infertility cases and affects around 7 percent of men. Our data showed that the nature of the sperm preparation medium affects sperm motility and the DNA integrity of the prepared spermatozoa.
Vitrolife - Sperm preparation
Sperm morphology is assessed using one of 2 sets of characteristics. Addition of penicilamine, hypotaurine, and epinephrine or bovine oviductal epithelial cells alone or in combination to bovine in vitro fertilization medium increases the subsequent embryo cleavage rate. Acta Zoolog Sin ; C , Comparison of 2 indices for 4 channels with lengths of 5, 7, 10, and 15 mm. Pregnancies from biopsied human preimplantation embryos sexed by Y-specific DNA amplification.
Results: Activation of semen sample groups by using of FertiCult Flushing medium, Theophylline solution and SpermMobil dilution in this study resulted in significant reduction in sperm concentration and highly significant improvement P [ Huda S. Distribution of mucus and sperm in bovine oviducts after artificial insemination. ClinExpObstet Gynecol. Non-progressive motility refers to sperm that do not travel in straight lines or that swim in very tight circles. Addition of penicilamine, hypotaurine, and epinephrine or bovine oviductal epithelial cells alone or in combination to bovine in vitro fertilization medium increases the subsequent embryo cleavage rate.
