In vitro fertilization (IVF) is a process by which egg cells are fertilised by sperm outside the body, in vitro. IVF is a major treatment in infertility when other methods of assisted reproductive technology have failed. The process involves hormonally controlling the ovulatory process, removing ova (eggs) from the woman's ovaries and letting sperm fertilise them in a fluid medium.

Does a low or zero sperm count make fertilization and pregnancy even with IVF impossible or extremely unlikely?
A normal sperm count offers the best chance for natural conception, because only a small percentage of millions of sperm in the ejaculate reach the fallopian tube, where the egg can be fertilized. Drug treatments and varicocele operations designed to increase sperm count, in truth do not have any beneficial effect. However, ICSI for the lowest sperm counts, and sperm extraction with ICSI for "zero" sperm, now give pregnancy rates with IVF no different than in men with normal sperm counts.
