To evaluate the effect of exogenous luteinizing hormone on IVF/ICSI success.

Retrospective clinical study.

2nd Department of Gynaecology and Obstetrics, Medical Faculty and L. Pasteur University Hospital Košice, Slovak Republic.

Individual parameters and clinical pregnancy rate of 232 IVF/ICSI cycles were compared in dependence on stimulation protocol (pure rFSH vs. rFSH and 75 IU rLH from S7).

There was no statistically significant difference in IVF/ICSI success between individual groups and subgroups, but we demonstrated the increase in clinical pregnancy rate per ET in agonist cycles group with exogenous LH activity totally above 11% (27.6% vs. 38.6%), in patients under 35 years above 12% (30.4% vs. 42.6%) and in patients over 35 years above 14% (16.7% vs. 30.8%). In antagonist cycles group there was demonstrated the increase in clinical pregnancy rate only in women over 35 years - above 14% (13.3% vs. 30.8%).

Despite of negative statistical analyses, from the clinical point of view we can strongly recommend the LH addition during COH, especially in agonist cycles and in older women.
