OBJECTIVE: To evaluate the efficacy of recombinant LH (r-LH) addition in the late phase of ovarian stimulation in patients with repeated implantation failure (RIF).
PATIENTS AND METHODS: 66 infertile couples undergoing ICSI treatment due to male factor were allocated to group A (33) and to group B (33). Group A (29 subjects) received recombinant FSH (r-FSH) supplemented by r-LH in the late follicular phase starting the same day of GnRH-antagonist (GnRH-ant) administration, and group B (32 subjects) received r-FSH alone. All patients were stimulated with a GnRH-ant flexible protocol starting r-FSH on day 2 of a spontaneous or induced cycle. hCG (10000 IU) was administered by intramuscular route when at least 2 follicles reached 18 mm in diameter.
RESULTS: Metaphase II (MII) oocytes with cytoplasmic maturation showed a significant difference in the r-LH group (89.02%) compared to the one with FSH alone (81.15%) (p < 0.01). The number of positive pregnancy test, 14 (48.3%) and 8 (25%), was significantly greater in the r-LH group compared to the group treated with r-FSH alone (p < 0.03). The number of gestational sacs was 20 in the r-LH group vs. 9 in the r-FSH group (p < 0.001). The implantation rate was significantly higher in the r-LH group compared to the r-FSH only group (19% vs. 7% respectively; p < 0.01). Also, a lower abortion rate was found in the r-LH group (21% vs. 37.5% respectively – p < 0.01).
CONCLUSIONS: Ovarian stimulation should be personalized because it seems that some subgroups of patients, like those with RIF, reach a better clinical outcome with the addition of r-LH in the advanced follicular phase stimulation.Free PDF Download
