Sperm abnormalities and effect on viability of embryos

There seems to be lots of information on how IVF and especially ICSI can lead to fertilisation where sperm test results are abnormal. However, much of the information published seems to position ICSI as a cure for men with low sperm counts. I have read that the sperm preparation process that is carried out before IVF can help eliminate abnormal sperm but this is usually only successful in eliminating the sperm that don't swim properly - i.e. usually those with tail and mid-piece defects. If a man's sperm mostly have abnormal heads can these be eliminated using the sperm preparation techniques used for IVF treatment? If not, is it possible to select normally shaped sperm for use in ICSI? If it is possible, is this normally done for ICSI or do clinics simply pick a sperm at random from those that have been through the sperm preparation process? The reason I am asking this is that I have read that abnormally shaped sperm (especially those with abnormal heads) can successfully fertilise an egg, especially through the ICSI method, but the embryo usually dies after a few weeks. If me and my husband decide to have ICSI I would like to try and find a clinic that can select normally shaped sperm.
