Abstract:
Objectives:
To determine prognostic factors for achieving a pregnancy with intrauterine insemination (IUI) and IVF. To compare the effectiveness and cost-effectiveness of IUI and IVF based on semen analysis results.
Design:
Retrospective cohort study.
Setting:
Academic university hospital-based infertility "center".
Patients:
One thousand thirty-nine infertile couples undergoing 3,479 IUI cycles. Four hundred twenty-four infertile couples undergoing 551 IVF cycles.
Interventions:
IUI and IVF treatment.
Main Outcome Measure(s):
Multiple logistic regression analysis was used to assess the significance of prognostic factors including a woman's age, gravidity, duration of infertility, diagnoses, use of ovulation induction, and sperm parameters for predicting the outcomes of clinical pregnancy and live birth rate after the first cycle of IUI and IVF. The relative effectiveness and cost-effectiveness of these treatments were then determined based on sperm count results.
Results:
Female age, gravidity, and use of ovulation induction were all independent factors in predicting pregnancy after IUI. The average total motile sperm count in the ejaculate was also an important factor, with a threshold value of 10 million. For IVF, only female age was an important predictor for both clinical and ongoing pregnancy. When the average total motile sperm count was under 10 million, IVF with ICSI was more cost-effective than IUI in our clinic.
Conclusion(s):
An average total motile sperm count of 10 million may be a useful threshold value for decisions about treating a couple with IUI or IVF. Copyright (C) 2001 American Society for Reproductive Medicine.
