ABSTRACT
Male factor infertility is a general term that describes couples in whom the inability to conceive is associated with a problem identified in the male partner. This problem may be classified into the following etiologies: low sperm production (oligospermia), poor sperm motility (asthenospermia), or abnormal sperm morphology (teratospermia) (1). Male factor infertility also describes men who may have normal sperm production but also exhibit conditions that prevent sperm transport to the vagina during intercourse (e.g., reproductive tract obstruction or ejaculatory dysfunction).
