BACKGROUND: This study was aimed to evaluate the effect of different recombinant LH (rLH) doses on the ovarian outcome of normogonadotrophic women with an initial inadequate response to recombinant FSH (rFSH) after pituitary downregulation. METHODS:Only women undergoing a 'long protocol' with a GnRH-agonist followed by rFSH administration were enrolled. On the eighth day of stimulation, 46 patients with serum E2 levels < 180 pg/ml and with no follicle > 10 mm were randomized in two groups to receive a supplementation with a daily rLH dose of 75 (group A) or 150 IU (group B), respectively. Forty-six normal responders continuing their monotherapy with rFSH formed the control group (C). RESULTS: The mean number of oocytes retrieved and the percentage of mature oocytes in the group B (9.65 +/- 2.16, 79.0%) were comparable with those observed in the group C (10.65 +/- 2.8, 82.5%) and significantly higher when compared with the group A (6.39 +/- 1.53, 65.7%). The mean number of ampoules of rLH was significantly higher in the group B (14.4 +/- 2.0 vs. 9.65 +/- 1.1), whereas these patients received a significantly lower mean number of rFSH ampoules (44.6 +/- 7.4 vs. 36.1 +/- 3.8). Seven (30.4%), 9 (39.1%) and 22 (47.8%) pregnancies were achieved in the groups A, B and C, respectively. CONCLUSIONS: These results suggest that patients with initial inadequate responses to rFSH after pituitary downregulation benefit from the addition of a daily dose of 150 IU of rLH, starting from the eighth day of stimulation.
