    Abstract:
    BACKGROUND: Intrauterine insemination is usually proposed as the first line therapy for infertility related to cervical hostility, male factor, unexplained infertility or mild endometriosis. The overall succes rate of IUI is about 10-20% clinial pregnancy per cycle. The Aim of this study is to evaluate factors that increase the succes rate of IUI. METHODS: we restrospectively analysed 206 cycles of IUI with partner's semen in 138 infertile couples. The clinical and laboratory factors that may influence the pregnancy rates were analysed: women's age, etiology of infertility, duration of infertility, ovarian stimulation, day of hCG and sperm parametres. RESULTS: The per-cycle clinical pregnancy rate was of 14.56%. Optimal pregnancy rates were observed in less than 38 years old women (18.29% vs 9.52%, p<0.05). The succes rate was statistically depending of the number of IUI cycles until three (p<0.05), the day of hCG (p<0.05) and the sperm count after conventionally prepared semen (p<0.05). Sperm parameters was of no value in predecting the pregnancy rates, and neither seam's to be the total dose of administrated Gonadotrophin or the etiology of infertility, but it seams that, when a cervical factor or PCO were involved, the succes rate is higher. Besides, getting three or more than three follicles may increase the succes rate but expose to a warrying risk of multiple pregnancy. CONCLUSION: According to this study, the only statitically significant factors that are associated with successful IUI were, women partner's age (<38 ans), number of IUI cycles (during the first three IUI cycles), day of hCG (>J13) and sperm count after conventional semen preparation (>1.106/mL).
