Sperm preparation by density gradient Three commonly used commercially available density gradients were used. This confirms that the efficacy of the gradient method is more pronounced in those couples with the diagnosis of unexplained subfertility where sperm parameters are in the normal range. This is a prospective cohort study. This result is in contrast with data reported by Petyim and colleagues [ 36 ] who observed a statistically significant difference with respect to progressive motility between samples processed for swim-up prior to cryopreservation and samples processed following cryopreservation: Pureception is comprised of an 80 percent vol.

Variability in the human-hamster in vitro assay for fertility evaluation. Subjects who present with significant amount of DNA damage prior to sperm preparation may exhibit sperm amount of DNA damage after sperm preparation. This lowercase translateProductType product. At the same time, cellular debris must be removed, including round cells, epithelial cells, white blood cells as well as immature or morphologically abnormal spermatozoa that are immotile or have poor motility.

Call us toll free at In male subfertile patients, both techniques yield similar clinical outcomes. Consult with your local Cook representative, distribution company or customer support center for details. All of the patients underwent a complete infertility evaluation including mid-luteal progesteron levels to assess ovulation, hysterosalpingogram HSG , and semen analysis. The only study that compared sperm chromatin and DNA content after gradient and swim-up preparation showed that the gradient technique was much more successful [ 15 ].

Although the sperm preparation method is the crucial step of IUI, less attention has been paid to the effect of sperm preparation techniques on IUI outcome. For example, the presence of dead spermatozoa, cellular debris, bacteria, or leukocytes detrimentally affects sperm survival and the fertility potential after thawing through ROS generation process [ 37 ]. Following this, the sperm preparation process was initiated. We aimed to compare the effectiveness of the two mostly used sperm preparation techniques swim-up vs dansity gradient on IUI sucsess. The basic premise of any sperm preparation technique is to a eliminate any factors detrimental to fertilization, b to block factors such as prostaglandins that would otherwise cause uterine contractions, c to increase sperm concentration, motility and d to form sperm capacitation.

Content of significant amounts of a cytotoxic end-product of lipid peroxidation in human semen.
