Trial summary
The present prospective study was designed to compare the effects of administering a daily dose of gonadotrophin releasing hormone (GnRH) antagonist vs. an alternate-day dosage of GnRH agonist on ovarian response and in vitro fertilization (IVF) outcome in patients stimulated with recombinant follicle-stimulating… Read more about this study

About this study
Official title: Effect of Ovarian Stimulation Using Recombinant FSH and GHRH Antagonist in Alternate Days on ICSI Outcomes
The present prospective study was designed to compare the effects of administering a daily dose of gonadotrophin releasing hormone (GnRH) antagonist vs. an alternate-day dosage of GnRH agonist on ovarian response and in vitro fertilization (IVF) outcome in patients stimulated with recombinant follicle-stimulating hormone (FSH) and human chorionic gonadotrophin (hCG) microdose.
Read the detailed description
Inclusion criteria were as follows: women of good physical and mental health, under 37 years old, with regular menstrual cycles of 25-35 days, normal basal FSH and luteinizing hormone (LH) levels, body mass index (BMI) less than 30 kg/m2, presence of both ovaries and intact uterus, absence of polycystic ovaries, endometriosis, or gynaecological / medical disorders and a negative result in a screening for sexually transmitted diseases.
No patient had received any hormone therapy for at least 60 days preceding the study. Eligible patients who agreed to participate were randomized in two treatment groups. Patients were allocated to a GnRH analogue treatment group according to a computer-generated randomization table.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
TriptorelinDrug
Also called Gonapeptyl
Triptorelin (0.1 mg, Gonapeptyl® Daily; Ferring, Kiel, Germany) in alternate-days from Day 1 of the menstrual cycle until the day of hCG administration.
CetrorelixDrug
Also called Cetrotide
When patients presented at least two follicles ≥ 14mm upon scan on days 7- 9, GnRH antagonist (cetrorelix, 0.25 mg/day, Cetrotide®; EMD Serono, Inc, Rockland, MA, USA) administration is started and continued until hCG administration.
| Study group | Role | What they receive |
|---|---|---|
| GnRH agonist | Experimental | Administration of GnRH agonist in alternate days, recombinant FSH and hCG microdose for ovarian stimulation. Receives: Drug: Triptorelin |
| GnRH antagonist | Active comparator | Daily administration of GnRH antagonist, recombinant FSH and hCG microdose for ovarian stimulation. Receives: Drug: Cetrorelix |

The record says: finished, as of the sponsor's last update on 13 Jul 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
cost of treatment (time frame: One month). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01468441, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jul 2012; AzTrials last refreshed its copy on 8 Nov 2026.
