Effect of Sperm Selection Techniques on Human Neonatal Gender Ratio in Patients Undergoing ICSI

semen was layered over 50 % and 90% discontinuous Density Gradient layers in a 15ml conical tube, then centrifuged at 250 g for 8 min at room temperature. supernatant was aspirated and the resulted pellet was washed using Sperm wash media and centrifuged at 250 g for 8 min at room temperature. The final pellet was re suspended in residual volume

Semen processing is done by double layer density gradient method followed by adding Sperm to the dot of hyaluronan on the PICSI dish, within minutes the bound sperm are attached by their acrosome to the surface of the dot. Hyaluronan bound sperms are selected for oocyte injection

Semen processing is done by double layer density gradient method. The resulted pellet is labeled with Annexin V microbeads followed by separation on MACS column, the eluted fraction contains non apoptotic sperms suitable for oocyte injection.
