Intrauterine insemination with husband semen: an evaluation of pregnancy rate and factors affecting outcome.

PURPOSE: The aim was to determine pregnancy rate following intrauterine insemination (IUI) and its associated factors in a university assisted reproductive technique center in Tehran, Iran.

METHODS

A retrospective analysis of 350 IUI cycles with ovarian stimulation by clomiphene citrate and/or gonadotropins was performed.

RESULTS

The overall pregnancy rate was 22% (77/350). Of the 77 pregnancies, 88.3% resulted in live birth, 7.8% in spontaneous abortion, 2.6% in blighted ovum and 1.3% were ectopic. Logistic regression analysis revealed three predictive variables as regards pregnancy: number of the treatment cycle (OR:3.5 CI:1.9 - 6.4 p:0.006), duration of infertility (OR:2.1 CI:1.2 - 3.7 p = 0.001) and age (OR:2.15 CI:1.1 - 4.4 p = 0.04). Pregnancy rate did not have any independent relation to sperm count, type of infertility, number and size of follicle and side of ovulatory ovary.

CONCLUSION

Our results indicate that clomiphene citrate and/or gonadotropins IUI is a convenient and useful treatment option in women with younger age ( <30 years) and fewer treatment cycles and fewer infertility duration (4 years).
