OBJECTIVE: The objective of the study was to determine the fecundity of young women (<35 years) with an elevated day 3 follicle stimulating hormone (FSH) undergoing gonadotropin-stimulation/intrauterine insemination.
STUDY DESIGN: This was a retrospective study. The study was conducted at an academic fertility center. A total of 1396 gonadotropin stimulation/intrauterine insemination cycles from 563 women were stratified by day 3 FSH levels (<10 vs ≥10 U/L) and outcomes were compared. Gonadotropin dose, treatment duration, peak estradiol (E2), number of preovulatory follicles (total, large, and medium size), E2/follicle, endometrial thickness, spontaneous abortion, clinical and multiple pregnancy rates were measured. The statistics included a Student t test, a χ(2), regression, and a discrete survival analysis.
RESULTS: An elevated day 3 FSH was found in 10.2% of the women, despite favorable age (31.9 ± 2.5 years). Women with a day 3 FSH of 10 U/L or greater when compared with women with a normal day 3 level required significantly more medication (1058.9 ± 1106.0 vs 632.7 ± 477.5 IU, P < .0001) were triggered a day earlier (10.6 ± 2.4 vs 11.5 ± 2.9 days, P = .0006) and had E2 levels (on the day of and the day prior to human chorionic gonadotropin administration) that were significantly higher (529.5 ± 244.3 vs 450.0 ± 244.2 and 359.6 ± 141.7 vs 306.8 ± 160.9 pg/mL, respectively, P < .05). Clinical pregnancy rates were comparable among the groups (14.6 vs 14%, respectively, P > .05). Spontaneous abortion and multiple pregnancy rates were higher among women with an FSH of 10U/L or greater but not significantly so (27.8% vs 12.0%, 22.2% vs 13.8% for FSH of ≥10 vs FSH < or >10 U/L, P > .05).
CONCLUSION: Women younger than 35 years with an elevated day 3 FSH, when treated aggressively with gonadotropins have pregnancy rates comparable with those of women with a normal baseline FSH. To achieve this outcome, they need higher doses of medication to stimulate the production of a larger preovulatory follicular cohort.
