Effect Clomiphene vs Clomiphene Along With Pioglitazone on Ovarian Stimulation Rate

March 4, 2026 updated by: Kinza Azhar, PAEC General Hospital, Islamabad

Comparison of Clomiphene Citrate vs Clomiphene Citrate in Combination With Pioglitazone in Terms of Ovarian Stimulation and Pregnancy Rates Among Infertile Women Suffering From Polycystic Ovarian Syndrome

Women who meet the study requirements will be enrolled and randomly assigned by a computer system to receive either pioglitazone 30 mg daily or a placebo starting from the second day of their menstrual period for the same duration. All participants will also take clomiphene citrate 150 mg daily from day 3 to day 7 of the menstrual cycle. A transvaginal ultrasound will be performed on day 10 of the menstrual cycle to assess the growth of ovarian follicles, and the number of mature follicles (16-24 mm) will be recorded. If at least one mature follicle measuring 16-24 mm is present and the endometrial thickness is at least 7 mm, an injection of human chorionic gonadotropin (hCG) will be given to trigger ovulation, followed by an intrauterine insemination (IUI) procedure. Participants will be followed until the end of the menstrual cycle, and if the menstrual period is delayed by 5 days, a blood test for β-hCG will be performed to confirm pregnancy. Any side effects during the treatment period, such as swelling, fluid retention, blurred vision, or weight gain, will be recorded.

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

Patients fulfilling the inclusion criteria will be enrolled and randomized using computer-generated random numbers to receive either pioglitazone 30 mg daily or a placebo starting from the second day of menstruation for a similar duration. All participants will receive clomiphene citrate 150 mg between the third and seventh days of the menstrual cycle. Transvaginal sonography will be performed on the 10th day of the menstrual cycle, and the number of large follicles (16-24 mm) will be recorded. Human chorionic gonadotropin (hCG) will be administered to patients with at least one follicle measuring 16-24 mm and an endometrial thickness of at least 7 mm, followed by intrauterine insemination (IUI). Patients will be followed until the end of the menstrual cycle, and in cases of a 5-day delay in menstruation, a blood sample will be obtained to measure β-hCG for biochemical confirmation of pregnancy. Any adverse effects observed during the treatment period, including edema, fluid retention, blurred vision, or weight gain, will be documented.

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

  • Adult

Accepts Healthy Volunteers

What is the study measuring?

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.
Outcome Measure
Measure Description
Time Frame
Ovarian stimulation rate
Time Frame: 10th day of menstrual cycle
This will be determined by no. of large size follicles (16-24mm in size) recruited following treatment on 10th day of menstrual cycle using transvaginal ultrasound to measure the size and no. of follicles.
10th day of menstrual cycle

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Pregnancy rates
Time Frame: 5th day after end of menstrual cycle
It will be measured in terms of number of patients out of total number treated who conceived. This will be confirmed clinically as well as by measuring serum bHCG levels if patient doesn't not menstruate for more than 5 days following end of her reproductive cycle.
5th day after end of menstrual cycle
