The endometrial biopsy is still a precise screening tool for the evaluation of the infertile couple.
OBJECTIVE: To compare the clinical outcome of controlled ovarian hyperstimulation (COH) in unselected patients undergoing IVF using multidose ganirelix acetate versus 4 days of administration of leuprolide acetate. DESIGN: Retrospective cohort study. SETTING: A fertility and IVF center. PATIENT(S): Two hundred forty-seven women who underwent COH-IVF between April 1, 1999, and January 30, 2001. INTERVENTION(S): Pituitary suppression according to a 4-day follicular phase leuprolide acetate protocol (236 women) or a multidose ganirelix acetate regimen (133 women). MAIN OUTCOME MEASURE(S): Amount of gonadotropin used, days of stimulation, cancellation rate, number of oocytes retrieved, implantation rate, and clinical pregnancy rate. RESULT(S): Compared with leuprolide acetate recipients, ganirelix recipients required significantly less gonadotropin and the mean day of hCG administration was 4 days earlier. Among women younger than 35 years of age, the implantation rate (15% vs. 6%) and the clinical pregnancy rate per initiated and transferred cycle (27% vs. 12% and 32% vs. 15%, respectively) were significantly higher in the ganirelix group than the leuprolide acetate group. CONCLUSION(S): Compared with a 4-day leuprolide acetate protocol, COH-IVF using a multidose ganirelix acetate protocol reduces treatment duration and amount of gonadotropin used. In younger women, the latter protocol is associated with significantly better pregnancy and implantation rates.
OBJECTIVE: To identify the cut-off values of the baseline (cycle day 3) levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol (E(2)) for improving the outcome prediction of GnRH antagonist in vitro fertilization (IVF) cycles and to determine whether the predictive accuracy of these values is affected by the patient's clinical prognosis. DESIGN: Retrospective analysis. SETTING: An IVF clinic in a tertiary medical center. Women undergoing 230 consecutive IVF cycles using a GnRH antagonist protocol. INTERVENTION: None. MAIN OUTCOME MEASURE(S): Outcome of IVF, measured by ovarian response and pregnancy rates. RESULT(S): Lower baseline levels of FSH and E(2), but not LH, correlated with improved ovarian response and pregnancy rates in IVF cycles using a GnRH antagonist. Compared with our currently used criteria, the cut-off values of FSH <10 IU/L and E(2) <56 pg/mL would have significantly improved the IVF outcome in a population of patients with normal prognosis. However, a stricter baseline FSH cut-off value of 8 IU/L would have been required to improve the IVF outcome in a population of patients with a poor prognosis. CONCLUSION(S): The outcome of IVF may be improved by modifying the hormonal starting criteria to take into account individual patient characteristics such as clinical prognosis.
