Asthenozoospermia refers to motility issues in the sperm. If the percent of sperm with poor or non-existent motility is high, it is unlikely that sperm are able to swim toward the egg and fertilize it after the insemination. Thus, although it depends on the level of severity of asthenozoospermia, it is better if you go directly for IVF with ICSI.
Can you undergo IUI with moderate asthenozoospermia?
