About this study

Official title: "Study of the Effects of Serum and Follicular Fluid Relaxin Levels on Ovarian Function in IVF Cycles as a Part of the Project "Relaxifert" "

The study evaluated the effect of serum relaxin and follicular fluid levels on the number and quality of oocytes, fertilization, the number and quality of the embryos in IVF protocols.

Read the detailed description

Relaxin is one of the promising indicators of oocyte quality and prognosis of the effectiveness of invitro fertilization protocols. The hormone plays an important role in the processes of folliculogenesis, growth and maturation of oocytes, development of embryos, implantation processes, pregnancy and childbirth. A pilot study was conducted on a group of patients undergoing infertility treatment using assisted reproductive technologies in the superovulation stimulation protocol using gonadotropin releasing hormone antagonists. Blood and follicular fluid samples were obtained on the day of transvaginal follicular puncture. The results allow us to consider the hormone relaxin as a promising predictor of the result of ovarian stimulation, the effectiveness of fertilization in IVF cycles.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Relaxin ELISA KitDiagnostic test

    Ovarian stimulation was carried out from day 3 of the menstrual cycle using a fixed protocol, with recombinant (Gonal-F, Pergoveris) or human menopausal gonadotropins (Meriofert), GnRH antagonist (ganirelix 0.25 mg). A recombinant human chorionic gonadotropin Ovitrel 250 μg or a GnRH agonist, Diferelin 0.2 mg, was used as an ovulation trigger.

Examination of relaxin levelsThis is a pilot study of 1 group of patients. The analysis of relaxin levels in serum and follicular fluid obtained on the day of puncture of the follicles in patients undergoing treatment in the IVF protocol is carried out.
Receives: Diagnostic Test: Relaxin ELISA Kit

What is being measured

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

  1. Correlation between the relaxin values in follicular fluid and the number of oocytes obtained

    The level of relaxin in follicular fluid was estimated using an ELISA Kit for Relaxin 2. The range of detectable concentrations was 3.1-500 pg / ml. Higher relaxin concentrations in follicular fluid are associated with a higher number of oocytes obtained.

    Measured: 10-14 days from the start of stimulation in the IVF protocol ( the day of transvaginal follicular puncture)

Secondary outcomes (3)
  1. Correlation between the relaxin levels in follicular fluid and oocyte fertilization efficiency

    The level of relaxin in follicular fluid was estimated using an ELISA Kit for Relaxin 2. The range of detected concentrations was 3.1-500 pg / ml. In course of standard IVF technique the fertilization efficacy was evaluated as a ratio of double pro-nucleus zygote on the 1st day of development to obtained oocyte-cumulus complexes number. In course of ICSI the efficacy was estimated as ratio of double pro-nucleus zygote on the 1st day of development to oocyte number on MII stage on puncture day. Higher concentrations of follicular fluid relaxin are associated with a decrease efficacy of oocyte fertilization

    Measured: 10-14 days from the start of stimulation in the IVF protocol for relaxin. The first day after transvaginal follicular puncture for evaluation oocyte fertilization efficiency.

  2. Correlation between the relaxin levels in follicular fluid and age

    The method of relaxin determining in follicular fluid and the range of determined concentrations are described previously. With increasing age, a decrease in the concentration of relaxin in the follicular fluid was noted.

    Measured: 10-14 days from the start of stimulation in the IVF protocol

  3. Correlation between the relaxin levels in follicular fluid and BMI

    The method of relaxin determining in follicular fluid and the range of determined concentrations are described previously. With increasing of BMI, a decrease in the concentration of relaxin in the follicular fluid was noted.

    Measured: 10-14 days from the start of stimulation in the IVF protocol

Questions about this trial

What is this clinical trial studying?

An observational study of Infertility and Reproductive Techniques, Assisted, run by D.O. Ott Research Institute of Obstetrics, Gynecology, and Reproductology at 1 site in Russia.

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 8 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 7 Jul 2020. 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 Russia. 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?

Correlation between the relaxin values in follicular fluid and the number of oocytes obtained (time frame: 10-14 days from the start of stimulation in the IVF protocol ( the day of transvaginal follicular puncture)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 7 Jul 2020.
