2 Clinical Trials for Various Conditions
Patients with chronic anovulation presenting to the IVF clinic for subfertility treatment are at increased risk of endometrial hyperplasia and carcinoma.They are often subjected to endometrial biopsy to rule out any underlying changes such as endometrial hyperplasia or carcinoma before commencing any further treatment. Literature shows that these group of patients have higher possibility of having underlying uterine abnormality (uterine polyp, fibroid, septum, or adhesion) and if we perform only endometrial biopsy, these structural abnormalities will remain undetected. And presence of uterine abnormalities lead to difficulty in implantation, which eventually leads to lower success rate of infertility treatment. WE propose that performing simultaneous office hysteroscopy followed by endometrial biopsy in such patients will lead to higher detection of uterine structural abnormalities and obtaining endometrial tissue to rule out hyperplasia or carcinoma. The concern for clinicians at times is that performing both the procedures together will lead to higher pain perception during the procedure. But with the introduction of flexible hysteroscope which has a diameter of 3.5 mm we hypothesize that the pain of performing office hysteroscopy with endometrial biopsy and performing endometrial biopsy alone will be equivalent. Meanwhile, hysteroscopy will lead lead to detection of underlying uterine pathology and help us in taking directed biopsies.
The purpose of our study was to conduct a placebo controlled, double-blind randomized trial in chronic oligoovulatory or anovulatory , hyperandrogenic, infertility patients comparing the effects of adjuvant metformin plus clomiphene citrate to clomiphene citrate plus placebo on pregnancy rates and ovulation rates. We hypothesized that combining metformin with clomiphene citrate would result in higher ovulation and pregnancy rates in hyperandrogenic women who have chronic oligoovulation or anovulation as the sole etiology for their infertility and who have unknown responsiveness to clomiphene citrate.
