Abstract

Background

The use of oral progestin has been shown to effectively prevent luteining hormone (LH) surge during ovarian stimulation with daily human menopausal gonadotropin injections. This study was aimed to investigate the efficacy of long-acting follicle stimulating hormone (long-acting FSH; corifollitropin alfa, Elonva®) use in progestin-primed ovarian stimulation for normal and high responders undergoing IVF/ICSI.

Methods

This is a retrospective and proof-of-concept study. We developed an extremely patient-friendly protocol to be applied to forty-five normal or high responders, in which a single injection of corifollitropin alfa (Elonva®) was administered and medroxyprogesterone acetate (MPA) was taken orally every day from the day after Elonva injection to the day of trigger. Seven days after Elonva injection, folliculometry and hormone tests were performed, followed by short-acting daily FSH/LH injections, if needed, until the day before trigger. Duration of stimulation, number of injections and visits before trigger, incidence of premature LH surge, the number of oocytes retrieved, fertilization rate, cleavage rate, the rate of day 2 good embryos available, and cumulative ongoing pregnancy rate per retrieval were assessed.

Results

The average age of the population was 34.7 years. Duration of stimulation was 9.4 days in average. Before trigger, only 3.6 injection shots and 1.4 visits were needed on average. There was no case of premature LH surge. Number of oocytes retrieved was 13.7, fertilization rate was 79.04%, cleavage rate was 91.11%, and day 2 good embryo rate was 64.34%, in average respectively. There was no case of ovarian hyperstimulation syndrome. The cumulative ongoing pregnancy rate per oocyte retrieval achieved a satisfactory level as 53.1%.

Conclusions

Our protocol consisting of long-acting FSH injection and oral MPA preventing LH surge reduces the number of injections and visits to an extreme and achieves a satisfactory reproductive outcome, and, therefore, is a really patient-friendly and effective approach to ovarian stimulation.
