Official Title: A Randomized Controlled Trial to Compare Fertilizations With Immotile Sperm After Pentoxyphylline Activation Alone, or With Chemical Oocyte Activation
Brief Summary: Immotile sperm is a rather frequent problem encountered in IVF patients. Treatment is usually based on inducing motility with pentoxyphylline (PXN) followed by ICSI. However, fertilization rate with this method is still lower compared with ICSI using motile sperm. One of the reasons for that is the immotile sperm inability to activate the oocyte Our research hypothesis is that better fertilization rate can be accomplished in these cases by combining PXN sperm activation with Ca ionophore oocyte activation.
