[Use of buserelin in a fertilization in vitro-embryo transfer program and determination of steroid concentrations of preovulatory follicular fluid].
Eleven infertility patients, stimulated by Buserelin/hMG/hCG protocol (BHh group) for superovulation, were compared with thirteen patients using CC/hMG/hCG protocol (CHh group) in an IVF-ET program. The rates of oocyte retrieval, fertilization and cleavage in BHh group were significantly, higher than those in CHh group. Furthermore, the incidence of premature LH surge in BHh group was 0% and 23.1% in CHh group. Eventually there were four pregnancies in BHh group and only one in CHh group. The mean concentrations of estradiol (E2), progesterone (P) and P/E2 ratio in follicular fluid (FF) in BHh group were significantly lower than that in CHh group. The values of FF P/E2 ratio in the range of 10-50 were positively correlated with oocyte fertilization rates. These data suggested that the addition of Buserelin in the superovulation protocol improved the outcome of IVF-ET treatment.
