October 27, 2023 updated by: Mohamed Sayed Abdelhafez, Mansoura University

Dual Trigger Versus Gonadotropin Releasing Hormone Agonist Trigger Combined With Luteal Human Chorionic Gonadotropin Administration

Comparing the reproductive outcomes of intracytoplasmic sperm injection (ICSI) cycles in women at risk of ovarian hyperstimulation syndrome (OHSS) subjected to gonadotropin releasing hormone (GnRH) antagonist protocol followed by trigger with concomitant GnRH agonist (GnRHa) and low-dose human chorionic gonadotropin (HCG) administration (dual trigger), GnRHa trigger with single luteal low-dose HCG or GnRHa trigger with multiple luteal low-doses HCG

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The GnRH antagonist fixed protocol will be used for controlled ovarian hyperstimulation (COH). Transvaginal sonography (TVS) scan will be performed regularly for monitoring of the follicular growth (folliculometry). When there will be at least 3 leading follicles > 18 mm in diameter, women will be randomized into 3 groups; group A (dual trigger group), group B (single low-dose HCG group) and group C (multiple low-doses HCG group). In group A, final oocyte maturation will be triggered by dual administration of 0.2 mg of GnRHa preparation (Triptorelin) SC and 1500 IU of HCG preparation IM. In group B, final oocyte maturation will be triggered by administration of 0.2 mg Triptorelin SC then a single IM bolus of 1500 IU HCG will by administered 35-37 hours after GnRHa trigger (1 hour after oocyte retrieval). In group C, final oocyte maturation will be triggered by administration of 0.2 mg Triptorelin SC then 3 IM boluses of 500 IU HCG will be administered day 1, day 4 and day 7 after oocyte retrieval. In all women, oocyte retrieval will be performed 34-36 hours after trigger and endometrial preparation for embryo transfer (ET) will be started on the day of oocyte retrieval by giving 400 mg vaginal natural progesterone supplement once daily plus 4 mg oral estradiol valerate once daily.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years to 35 years (Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures
