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.

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Group C
Drug: Clomiphene Citrate.
150 mg clomiphene citrate will be administered at third and seventh days of the menstrual cycle
Active Comparator: Group CP

What is the study measuring?

Primary Outcome Measures

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

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
