Trial summary

Vitamin D has a major play in bone and calcium metabolism. Vitamin D deficiency (below 20 ng/ml) has also been linked to adverse health outcomes such as malignancy, cardiovascular disease, immune functioning, and glucose metabolism. Read more about this study

About this study

Official title: Serum Vitamin D Level in Subfertile Women and Its Association With Ovarian Reserve and IVF Outcome.

Vitamin D has a major play in bone and calcium metabolism. Vitamin D deficiency (below 20 ng/ml) has also been linked to adverse health outcomes such as malignancy, cardiovascular disease, immune functioning, and glucose metabolism. Recent data from retrospective and prospective trials have demonstrated contradictive results concerning the role of vitamin D in female reproduction and IVF outcome. Some studies have found that women deficient in vitamin D had lower ovarian reserve and significantly lower clinical pregnancy rates when compared to patients who were sufficient levels in vitamin D. Some studies also demonstrated that serum 25-OH-D3 levels correlates with antimullerian hormone (AMH) levels in women of advanced reproductive age. It may also have a role to play in endocrine dysfunction and abnormal folliculogenesis in polycystic ovaries .

The aim of this prospective cohort study including infertile women undergoing IVF treatment is to investigate the association between serum 25-OH- D3 levels and parametres of ovarian reserve (AMH, antral follicle count, number of oocytes collected) and clinical pregnancy and miscarriage rates .

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Clinical pregnancy rate

    Measured: 14 days post oocyte retrieval

Secondary outcomes (3)
  1. AMH (antimullerian hormone) Levels

    Measured: day 2-3 of the index cycle

  2. AFC (antral follicle count)

    Measured: DAY 2-3 OF INDEX CYCLE

  3. Number of oocytes retreived

    Measured: Two weeks from the last menstrual period

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 3 inclusion and 2 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: status not confirmed, as of the sponsor's last update on 16 Dec 2014. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Clinical pregnancy rate (time frame: 14 days post oocyte retrieval). 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 NCT02317718, which also lists 3 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 16 Dec 2014.
