About this study
Official title: Measurement of Different Anti-Müllerian Hormone Isoforms in Expected Poor Responders: Does it Matter?
This study wants to evaluate significant clinical impact of different AMH isoforms in serum can be present or absent in expected poor responder participants. The specific AMH isoforms could therefore be measured in expected poor responder participants in order to obtain a more realistic clinical picture and therefore be able to give proper information to the participants and selection of medication dose for ovarian stimulation.
Read the detailed description
The study has a prospective observational multicentric design and the investigators aim to investigate the presence of AMH isoforms and the levels of Inhibin B in serum among a population of participants with low ovarian reserve (AMH blood test below 1.1 ng/ml). Transvaginal scan for AFC and blood drawn from participants will be obtained on day 2-3 of menstrual period. The serum will be divided for AMH analysis using different assays: Elecsys Cobas assay for AMH and AnshLabs AMH isoforms specific assays (picoAMH 24/32 Pro-Mature, 24/37 Midpro-Midpro, 17/15 Mature-Mature and 10/24 Pro-Midpro) and AnshLabs Inhibin B ELISA.
Clinically it is not uncommon to see a discrepancy between the AFC count and the levels of AMH; this could be potentially explained by the presence of different AMH isoforms not measured with conventional commercial assays. Also, the evaluation of Inhibin B may be helpful for ovarian reserve assessment. Quantitation of specific Isoforms of AMH by different ELISA methods will investigate a possible relationship(s) between specific isoforms of AMH and poor responders.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study wants to evaluate significant clinical impact of different AMH isoforms in serum can be present or absent in expected poor responder participants. The specific AMH isoforms could therefore be measured in expected poor responder participants in order to obtain a more realistic clinical picture and therefore be able to give proper information to the participants and selection of medication dose for ovarian stimulation.
Detailed description
The study has a prospective observational multicentric design and the investigators aim to investigate the presence of AMH isoforms and the levels of Inhibin B in serum among a population of participants with low ovarian reserve (AMH blood test below 1.1 ng/ml). Transvaginal scan for AFC and blood drawn from participants will be obtained on day 2-3 of menstrual period. The serum will be divided for AMH analysis using different assays: Elecsys Cobas assay for AMH and AnshLabs AMH isoforms specific assays (picoAMH 24/32 Pro-Mature, 24/37 Midpro-Midpro, 17/15 Mature-Mature and 10/24 Pro-Midpro) and AnshLabs Inhibin B ELISA.
Clinically it is not uncommon to see a discrepancy between the AFC count and the levels of AMH; this could be potentially explained by the presence of different AMH isoforms not measured with conventional commercial assays.

Questions about this trial
What is this clinical trial studying?
An observational study of Anti-Mullerian Hormone Isoforms, run by ART Fertility Clinics LLC at 1 site in United Arab Emirates.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 8 Aug 2022. 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 United Arab Emirates. 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?
AMH serum levels (time frame: 1 day). 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 NCT03826888, which also lists 16 linked publications.
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 8 Aug 2022.
