Clinical Trial Summary

The aim of this study will be to compare between 4 different induction protocols in women who:

1. Failed to achieve ovulation after clomiphene citrate treatment at a dose of 150mg daily (if the patient can tolerate this dose) for 5 days for 3 cycles or only 100 mg daily for the same duration (if she can't tolerate higher dose)

2. Failed to achieve pregnancy after 3 cycles of ultrasound indicated ovulation with clomiphene citrate treatment at a dose of 100mg or 150mg daily.

All induction protocols will be carried out in non-IVF cycles, and continued for 3 cycles or until pregnancy whichever will be earlier.

Description:

The study will include 4 treatment groups:

GROUP 1: Participants of this group will receive Letrozol (Femara, Novartis) at a dose of 2.5mg twice daily starting from day 3 of the cycle for 5 days.

GROUP 2: Participants of this group will receive Letrozol (Femara, Novartis) at a dose of 2.5mg twice daily starting from day 3 of the cycle for 5 days. Metformin (Cidophage 500 mg, Cid Pharmaceuticals, Egypt) 500 mg twice daily will also started from day 3 till the date of doing pregnancy test GROUP 3: Participants of this group will receive highly purified lyophilized Uroffollitropin (Fostimon, IBSA Institut Biochimique SA, Lugano, Switzerland.) at a dose of 75IU S.C or IM starting from day 3 of the cycle for 5 days. Readjustment of the dose will occur upon the results of day 8 folliculometry.

GROUP 4: Participants of this group will receive highly purified lyophilized Uroffollitropin (Fostimon, IBSA Institut Biochimique SA, Lugano, Switzerland.) at a dose of 75IU S.C or IM starting from day 3 of the cycle for 5 days. Readjustment of the dose will occur upon the results of day 8 folliculometry. Metformin (Cidophage 500 mg, Cid Pharmaceuticals, Egypt) 500 mg twice daily will also started from day 3 till the date of doing pregnancy test For follow up:US folliculometry will be done on Day 8 in all groups. Further appointments for folliculometry will be given upon the response. Dominant follicle will be diagnosed on Day 8 if the average follicular diameter is 12mm or more (taken in 2 perpendicular diameters) then follow up will be continued till the diameter reaching 18-22mm so that triggering ovulation will be carried out by administration of human chorionic gonadotrophins (Epifasi 5000 IU, ampoule, EIPICO pharmaceuticals, Egypt). All women will be advised to receive the injection within 12 hours of the last follicular measurement. Women will be advised to have unprotected intercourse 24-36h following hCG injection. Serum β-hCG will be measured after 2 weeks to check for pregnancy and US will be performed after 2-4 weeks from B-hCG results to confirm the presence of pregnancy.

Each couple will be involved in the study for 3 treatment cycles if pregnancy will not occur but still having the option not to continue in our study where we will manage them outside the study protocol.

Women who will get pregnant will be followed for 12w gestational age for possible detection of 1st trimester abortion.
