Article Description

Background: To compare the effect of the GnRH antagonist/letrozole/ gonadotropin protocol with the microdose GnRH agonist flare-up protocol in poor ovarian responders for intracytoplasmic sperm injection. Materials and methods: One hundred twenty-one consecutive patients suspected of having or with a history of poor ovarian response between January 2009 and June 2010, who were undergoing ICSI were enrolled. The microdose flareup (MF) protocol was used in 79 patients and the estradiol+progesterone/letrozole+gonadotropin and GnRH antagonist (EP/ALG) protocol was used in 42 patients. Results: Age of the patients, duration of infertility, basal FSH, the total gonadotropin consumption, duration of stimulation, E2 level on the day of hCG administration, the number of embryo transferred, the fertilization rate, implantation rate, clinical pregnancy rate and the live birth rate were not statistically different (p>0.05). Only the number of oocytes retrieved was significantly higher in the EP/LGA group (1.7±0.7 versus 2.6±0.6). Conclusion: The EP/LGA protocol has no significant improvement against the microdose flare-up protocol in poor responder patients. © 2014 Informa UK Ltd. All rights reserved.
