Basal Androgens and LH Needing for Ovarian Stimulation for in Vitro Fertilization

This study has been completed.
Sponsor:
Information provided by (Responsible Party):
Ernesto Bosch, Instituto Valenciano de Infertilidad, IVI VALENCIA
ClinicalTrials.gov Identifier:
NCT01563809
First received: March 22, 2012
Last updated: April 21, 2015
Last verified: April 2015
  Purpose
Basing the investigators study on the evidence that basal serum androgens decrease with age, the investigators hypothesize that women with serum androgens below a certain level could be the population obtaining a benefit of Luteinizing Hormone (LH) supplementation. The objective of the present study is to explore the relationship between basal serum androgen levels and the need of LH for Controlled Ovarian Stimulation (COS) in IVF.

Condition Intervention Phase
Infertility Drug: FSH+LH Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: The Relationship Between Basal Androgen Levels and the Needing of LH for Controlled Ovarian Stimulation for in Vitro Fertilization

Further study details as provided by Ernesto Bosch, Instituto Valenciano de Infertilidad, IVI VALENCIA:

Primary Outcome Measures:
  • Clinical Pregnancy Rate [ Time Frame: 45 days ]
    Use of rec LH supplementation for controlled ovarian stimulation for IVF


Enrollment: 400
Study Start Date: December 2008
Study Completion Date: December 2010
Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Low androgens FSH+LH
Patients with androgens below threshold receiving FSH+LH for ovarian stimulation
Drug: FSH+LH
75 IU of LH will be given from stimulation day 1
Active Comparator: High androgens FSH+LH
Patients with androgens above threshold receiving FSH+LH for ovarian stimulation
Drug: FSH+LH
75 IU of LH will be given from stimulation day 1
No Intervention: High androgens FSH alone
No Intervention: Low androgens, FSH alone

Detailed Description:

Design: Single centre, open label, randomized controlled trial.

  • Population: Patients with indication of In Vitro Fertilization (IVF) with the following criteria:
  • Protocol: All patients are tested on day 3-5 of cycle for total Testosterone (Te), Dehydroepiandrosetnodione sulphate (DHEAS) and Androstenodione (Δ4). Samples are frozen and stored at -20ºC for later analysis. FSH, LH, E2, PRL and TSH are also determined. All patients follow Controlled Ovarian Stimulation for IVF with a GnRH agonist long protocol. They are randomized to receive recombinant (r) FSH alone (225 IU/day) or r-FSH + r-LH (225+75 IU/day).
  • Sample size calculation: To detect a difference from 40 to 60% (Relative risk: 1.50) on pregnancy rate (PR) between patients with low and high androgen levels with respect to the mean of each COS protocol, with a confidence level of 95% (error α=0.05) and 80% of power (error β=0.2), 97 patients per arm were needed. (n=388 patients). Rounding up, 400 patients are to be recruited.
