Polycystic Ovary Syndrome Clinical Trial
Official title:
Effect of Nitric Oxide Donors on Uterine and Subendometrial Blood Flow in Patients With Unexplained Infertility
The purpose of the study to evaluate effect of nitroglycerin trans-dermal patches on uterine and sub-endometrial blood flow in women with unexplained infertility.
90 female patients will be divided into 2 equal groups:
- Group I: 30 female patients with unexplained infertility.
- Group II: 30 female patients with unexplained infertility will receive nitroglycerin
trans-dermal patch.
All subjects will be subjected to the following:
- Proper history taking on past medical history, menstrual history and infertility workup.
- Proper examination (general, abdominal and local examinations)
- Investigations to diagnose unexplained infertility ( male partner's semen analysis as
well as documented ovulation and a patent uterine cavity and Fallopian tubes in the
female partner).
- Group II (30 patients with unexplained infertility)will receive: (nitrodermal®) 5 mg
(patch)as a source of Nitric oxide from 2nd day of cycle till maturation of the
follicles ≥ 18 mm just for one cycle
- All women included in each group will be subjected to trans-vaginal ultrasound for
folliculometry till maturation of the follicle ≥18mm.
- Once the follicle reached ≥18 mm 3D power Doppler will be used to assess the uterine and
sub-endometrial blood flow.
- All women in each group will be subjected to urinary luteinizing hormone (LH) assay. The
urinary LH assay will be started on cycle day 11, and repeated daily till detection of
the LH surge.
- Six days after detection of the LH surge, 3D power Doppler will be repeated to assess
the uterine and sub-endometrial blood flow.
