The efficacy of intrauterine insemination with husband's semen (AIH) is well established for some types of infertility. Results that had been reported previously were Dwing difficult to assess owing to the low number of patients or treatment cycles as well as an inadequate definition of the indications in most cases. In this study, we report our experience with intrauterine insemination (IUI) using post-treated sperm suspension from husband's semen in the treatment of infertility. A total of 328 treatment cycles were completed from January to December in 1991. The indications for AIH/IUI were male infertility (130 cycles), unexplained infertility (87 cycles), sex selection (72 cycles) and anovulatory disorder (39 cycles). Sixty-eight pregnancies were achieved. The clinical usefulness of AIH/IUI with or without concomitant hMG regimens were established according to diagnostic subgroups. In our results, the cycle fecundity of pregnancy was higher in patients with ovulatory disturbance. The importance of sperm motility confirmed by our results that have compared by the serial sperm parameters. The motile sperm count may appear to be a highly consistent parameter that serves as a sensitive indicator of sperm function and correlation of successful pregnancy in our results. In conclusion, this study indicates that AIH with controlled ovarian hyperstimulation can result in higher viable pregnancy rate, and it is also a non-invasive and relatively easy procedure. We believe that this is a transient useful method for the treatment of non-organic infertility, prior to any attempt of aggressive assisted reproductive procedures.
