Detailed Description
The proposal of this study approved by our institutional review boards and institution's ethical committee, and all participants will sign a written consent before enter to study.
The study population will consist of infertile women of <38 years of age with repeated in vitro fertilization/ intra cytoplasmic injection failures. Endometrial parameters including endometrial thickness, endometrial pattern , pulsatility index (PI) and resistance index (RI) will be evaluated with the use of color Doppler ultrasound on the day of hCG administration. Patients will be randomly divided into 3 groups, A, B and C. In the subsequent menstrual cycle, in group A, vaginal sildenafil suppositories (100 mg/day) will be given daily from the start of human menopausal gonadotropin (HMG) administration day until the day of oocyte retrieval. In group B, the women will receive daily vaginal placebo from the start of HMG administration day until 2 days before the human chronic gonadotrophin (hCG) injection day, then will be switched to vaginal sildenafil suppositories (100 mg/day) until the day of oocyte retrieval. In group C, vaginal placebo will be given daily from the start of human menopausal gonadotropin (HMG) administration day until the day of oocyte retrieval.
When the diameter of at least 2 follicles will be reached equal or greater than 18 mm, hCG 10,000 IU will be administered. In all patients, ovarian stimulation will be performed with the conventional GnRh agonist protocol. Endometrial parameters will be measured again on the day of hCG injection. Ovum pick up will be performed 34-36 h after hCG injection and embryos will be transferred 48-72 hours after oocyte retrieval. Pregnancy will be confirmed by assessment of βHCG level 14 days after embryo transfer and ultrasonographic visualization of gestational sac during the 5th week of pregnancy.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Clinical Pregnancy rate
Time Frame: 4-6 weeks after embryos transfer
|
Evaluation the Clinical Pregnancy rate after using Sildenafil vaginal suppositories (100 mg/day) from the start of HMG administration day until the day of oocyte retrieval.
It is detected by a positive ß-hCG test result and ultrasonographic visualization of at least one gestational sac
|
4-6 weeks after embryos transfer
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Implantation rate
Time Frame: 4-6 weeks
|
The implantation rate is defined as number of gestational sacs per transferred embryo.
It Is detected by a positive ß-hCG test result and ultrasonographic visualization of at least one gestational sac 4-6 weeks after embryos transfer.
|
4-6 weeks
|
Endometrial thickness
Time Frame: 1 day
|
The endometrial thickness is detected by ultrasound examination in hCG day administration.
|
1 day
|
Endometrial pattern
Time Frame: Day 14
|
Comparing gray scale appearance of the endometrium to that of the adjacent myometrium at Day 14 of previous cycle.
|
Day 14
|
Pulsatility index
Time Frame: 1 day
|
The variability in flow between the systole and the diastole; this measure was calculated by dividing the difference between the peak systolic and end-diastolic frequencies by the time-average of the maximum frequency shift.This is measured at hCG administration day.
|
1 day
|
Resistance index (RI)
Time Frame: 1 day
|
The RI is defined as a ratio of the difference between the maximum and minimum flow velocity to maximum flow velocity.This is measured at hCG administration day.
|
1 day
