Abstract
This chapter considers the various causes of male infertility and the input of
the male into the overall process of fertility treatment. Fertility treatment is unique in
that it involves 2 patients at the same time and the role of these patients is equally
important to the overall success of the treatment. The male plays a critical role in
fertility treatment, and this role may be down-played by some fertility clinics to the
point at which the male feels disengaged from the treatment process. This is a bad
thing.
