Efficacy of Low Dose hCG on Oocyte Maturity for Ovarian Stimulation in Poor Responder Women Undergoing ICSI: a Prospective Randomized Controlled Trial

This study is a prospective, randomized, parallel, controlled trial to assess the efficacy of the late follicular phase administration of low dose hCG on oocyte maturity for ovarian stimulation in 73 poor respond patients undergoing intracytoplasmic sperm injection (ICSI) treatment.

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

In this study all eligible patients were randomly allocated into three study groups by a permuted block randomization method: group A (control group) received only recombinant FSH, group B received rFSH supplemented by 100IU hCG in the late follicular phase. Group C received rFSH supplemented by 200IU hCG in the late follicular phase.

All of the patients underwent a standard long protocol and received GnRH-a (Suprefact), 0.5cc subcutaneous, started from the day 17 of the preceding cycle and ovulation induction was started 14 days thereafter.

Patients were categorized according to the following stimulation protocols:

Group A (control group): which 300 IU r-FSH was administered for the first 5 days of the stimulation cycle. Then the first ultrasound scan was performed to monitor response. At this stage the dose of rFSH adjusted according to the ovarian response and continued until the day of ovulatory hCG administration.

Group B: rFSH supplemented with daily administration of 100 IU hCG in the late follicular phase based on the follicle size (14mm).

Group C: rFSH supplemented with daily administration of 200 IU hCG in the late follicular phase based on the follicle size (14mm).

To assess the pregnancy outcomes, serum hCG was measured 2 weeks after embryo transfer. Clinical pregnancy was defined by the observation of sac with fetal heart rate on ultrasonography 4 weeks after embryo transfer.

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

37 years to 43 years (Adult)

Accepts Healthy Volunteers

Yes

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
