About this trial

Does combined Cabergoline and letrozole increase ovulation rate What medical problems do participants have when taking drug Cabergoline and Letrozole ? Researchers will compare drug combination of Cabergoline and letrozole to letrozole alone to see combined cabergoline and letrozole works better as ovulation induction.

Participants will:

experimental group will receive Cabergoline and Letrozole comparator group will receive letrozole alone TVS Monitoring will be done for 3 cycle for ovarian response

1

Ovulation Rate

Ovulation will be diagnosed by presence of any one of following(Mandelbaum et al., 2024) * LH surge in ovulation predictor kit * Day 21 progesterone level ≥ 3 ng/dl * An appropriately timed menses in previously oligomenorrheic women * A positive pregnancy test

Time frame
Assessed within 21 days after each ovulation induction cycle for upto 12 weeks

Secondary outcomes

1

Presence of preovulatory follicle on D12 of cycle

Preovulatory follicle will have mean diameter measuring ≥ 14 mm as detected on day 12of cycle folliculometry

Time frame
assessed by TVS within 12 days after each ovulation induction cycle ,upto 12 weeks
2

Largest follicle size on D12 of cycle

The largest follicular diameter is measured by averaging the two maximum perpendicular internal diameters of the follicle.

Time frame
Assessed by TVS,within 12 days of each ovulation induction cycle ,upto 12 weeks
3

Pregnancy

Pregnancy will be determined after missed period by serum β-hCG estimation. Serum β-hCG\> 5 mIU/mL is diagnosed as pregnancy \[ Atellica integrated clinical chemistry and immunoassay analyzer\].
