What is the success rate for IVF with male factor infertility?

Since when doing IVF the best eggs are selected therefore male factor infertility shouldn't cause to much of a problem, there is also a form of IVF called ICSI where a woman undergoes IVF and specialists literally inject a sperm into the egg with a microinjector. As such, this procedure is often, but not always, used to treat male infertility, specifically disorders relating to the testes and sperm production.
