Duration of GnRH-analogue Downregulation and Pregnancy Rates
NCT00436319 · Status: TERMINATED · Phase: PHASE4 · Type: INTERVENTIONAL · Enrollment: 300
Last updated 2016-02-12
Summary
The purpose of this study is to assess whether the probability of pregnancy is dependent on the duration of GnRH agonist downregulation in IVF cycles.

-
Duration of GnRH agonist downregulation
This is a randomized controlled trial. Patients will be randomized to two groups during the first consultation. GnRH agonist will be administrated according to the long luteal protocol. Down-regulation of the pituitary will be controlled on the first day of the menstrual period. The purpose of this study is to compare the pregnancy rates between the two groups. In the eventuality that pituitary down-regulation has not been confirmed (down-regulation levels determined as Ε2\<80 pg/ml and progesterone \<1.6 ng/ml), the patient will be assigned to a third group (group 3) and ovarian stimulation will only be initiated after down-regulation has been confirmed. The GnRH agonist that will be administrated is Buserelin Acetate. Recombinant FSH will be used for the ovarian stimulation and dose determination will be based on patient characteristics and previous history.
