Intrauterine insemination with or without mild ovarian stimulation in couples with male subfertility due to oligo/astheno- and/or teratozoospermia or antisperm antibodies: a prospective cross-over trial.

Seventy-three couples with male subfertility, which was due to oligo/astheno- and/or teratozoospermia (n = 63) or antisperm antibodies (n = 10), were randomly assigned to sequential timed natural intercourse, intrauterine insemination (IUI) and IUI + mild ovarian hyperstimulation. From the analysis of 384 observed cycles, IUI was shown to be effective in oligo/asthenozoospermia without severe teratozoospermia, when it was associated with moderate multifollicular induction, and in male immunologic subfertility, IUI was highly effective in nonstimulated cycles also.
