Objective To analyze the value of evaluating ovarian response to gonadotrophin stimulation according to patients basal FSH / LH ratio. Methods A total of 134 patients undergoing IVF-ET or ICSI were enrolled using short protocol. We studied their age,basal FSH,bFSH/LH ratio and some indexes which can represent ovarian response. Statistical evaluation was performed using logistic regression analysis and ROC curve to determine odds ratios(OR) and FSH/LH cutoffs. Results Among the patients whose bFSH were less than 8 IU/L,three odds ratios between the ovarian response index and their age,bFSH,bFSH/LH were no significant difference and bFSH/LH cutoff was 3.7. But among the patients those bFSH ≥ 8 IU/L,there were differences among the three OR and bFSH/LH cutoff was 3.3. The highest OR was between bFSH/LH ratio and ovarian response indexes,while the lowest was between bFSH and those indexes . Conclusions Among the patients who has lower ovary reserve (bFSH ≥ 8 IU/L),the ratio of bFSH/LH has superior value to age and basal FSH on evaluating ovarian response.
