Objective: To compare the rate of premature luteinization in depot goserelin-downregulated in vitro fertilization (IVF) cycles with other IVF protocols at a teaching hospital in Ethiopia.
Methods: We conducted a cross-sectional study on the effects of premature luteinization on IVF outcomes at St. Paul's Hospital Millennium Medical College, a tertiary teaching hospital in Ethiopia. Patients who had IVF at this hospital between 2019 and 2020 were included in the study. Patient records were reviewed and collected on Open Data Kit. We used Stata release 15 to analyze the data. A simple descriptive analysis and bivariate analysis were performed as appropriate. A P-value less than 0.05 was considered as statistically significant.
Results: A total of 305 patients (40 cases with premature luteinization and 265 without premature luteinization) were included. There was no difference in the rate of premature luteinization in the depot goserelin long protocol cycles (6.4%), compared to minimal stimulation (14.1%) and antagonist protocols (16.7%), P = 0.19. Embryo transfer was carried out in 27 (67.5%) patients in the premature luteinization group, which was lower than the 86.0% (228/265) in the non-premature luteinization group, P = 0.003. There was no difference in the median number of oocytes retrieved (8.5 [interquartile range 5.0, 13.0] per cycle in the premature luteinization group vs 5.0 [interquartile range 3.0, 10.0] in those without premature luteinization, P = 0.10).
Conclusion: A depot goserelin-downregulated long protocol for IVF is a cost-effective and convenient option for controlled ovarian hyperstimulation without increased risk of having premature luteinization compared to antagonist and minimal stimulation protocols.
