The purpose of the present study is to examine the level of ovarian response and the pregnancy rates among poor ovarian responders treated with a novel treatment protocol with 150μg corifollitropin alfa followed by 300IU hMG in a short GnRH agonist protocol.

Enrollment: 51
Study Start Date: July 2012
Study Completion Date: May 2013
Primary Completion Date: May 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Corifollitropin alfa+hMG Drug: Triptorelin
Triptorelin 0.1 mg/1 ml solution daily from day 1 or 2 of the cycle onwards
Drug: Corifollitropin alfa
Corifollitropin alfa 150μg (single dose) on day 2 or 3 of the cycle
Drug: hpHMG
300IU hMG daily from day 7 following Corifollitropin alfa until the day of ovulation triggering

Detailed Description:

Corifollitropin alfa reaches maximum concentrations (Cmax), between 25 and 45 h after injection , a time interval which is significantly shorter as compared to treatment with rFSH. The investigators hypothesized that this rapid increase in the serum FSH concentration may result in a significantly higher exposure of the small antral follicles to constant high levels of FSH during the early follicular phase, securing not only the recruitment of the follicles, but also the continued growth.

In the current study the investigators examine whether administration of corifollitropin followed by 300IU hMG in a short GnRH agonist protocol may result in acceptable pregnancy rates in poor ovarian responders fulfilling the "Bologna criteria"


Ages Eligible for Study:   18 Years to 45 Years
Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   No

Inclusion Criteria:

Patients should fulfill the "Bologna criteria" for poor ovarian response

At least two of the following three features must be present:

i. Advanced maternal age (≥40 years) or any other risk factor for POR (poor ovarian response); ii. A previous POR (≤3 oocytes with a conventional stimulation protocol); iii. An abnormal ovarian reserve test (i.e. AFC <7 follicles or AMH <1.1 ng/ml).

Two episodes of POR after maximal stimulation are sufficient to define a patient as poor responder in the absence of advanced maternal age or abnormal ORT (ovarian reserve test).
