Oral contraceptive pretreatment does not improve outcome in microdose gonadotrophin-releasing hormone agonist protocol among poor responder intracytoplasmic sperm injection patients.
OBJECTIVE
To compare oral contraceptive (OC) pretreatment plus microdose GnRH-a in flare-up protocol and non-OC microdose GnRH-a in flare-up protocol among poor responder ICSI patients.


METHODS
A retrospective analysis of poor responder ICSI patients. Patients were divided into two groups according to used microdose protocol. Precycle treatment with OC followed by follicular phase administration of 40 microg s.c. leuprolide acetate (LA) every 12 h beginning on after 2 day pill-free period and rFSH administration was begun on the third day of LA administration (OC-Group, n=26). Alternatively on day 2 after menses, patients were administered similar stimulation regime (non-OC Group, n=27).


RESULTS
There were no significant differences between groups in the number of oocytes, peak estradiol levels, endometrial thickness, fertilization rates and embryo quality. Implantations and pregnancy rates per embryo transfer were similar.


CONCLUSIONS
OC pretreatment plus microdose GnRHa in flare-up protocol does not offer advantages over non-OC microdose GnRHa in flare-up protocol among poor responder ICSI patients.
