Measure
Traditional Administration
The traditional approach to ovulation induction with clomiphene citrate involves administration of 50mg/day for five days (starting on cycle day 5). If ovulation does not occur by day 21 then a progestin is prescribed to induce menses (which occurs within one week of stopping the progestin) and then a higher dose of medication is used in the next cycle. This process will be repeated at increased doses of clomiphene citrate (100 mg and 150 mg).
Stair-Step Administration
The stair-step protocol the dose of clomiphene citrate would be increased without administering progestin and inducing a period. This method utilizes ultrasound monitoring for follicle development before increasing the dose of clomiphene citrate.

Traditional Administration
n=60 Participants
The traditional approach to ovulation induction with clomiphene citrate involves administration of 50mg/day for five days (starting on cycle day 3, 4, or 5). If ovulation does not occur then a progestin is prescribed to induce menses (which occurs within one week of stopping the progestin) and then a higher dose of medication is used in the next cycle. clomiphene citrate: Clomiphene citrate 50 mg for 5 days starting on cycle day 5. Transvaginal ultrasound between cycle days 11 to 14 to determine if there is a dominant follicle. If NO dominant follicle present, another ultrasound and blood draw (to test progesterone level) will be done one week later to confirm no response to the medication dose. Medroxyprogesterone acetate (Provera) 10 mg per day for 10 days. Increased dose of clomiphene citrate for 5 days starting on cycle day 5. This process will be repeated at increased doses of clomiphene citrate (100 mg and 150 mg) until a dominant follicle(s) is present.
Stair-Step Administration
n=60 Participants
The stair-step protocol the dose of clomiphene citrate would be increased without administering progestin and inducing a period. This would eliminate the days of progestin (10 days) and the waiting for the period (usually 3 to 7 days) and finally waiting to start clomiphene citrate on cycle day 3 at the earliest (3 more days) for a total of up to 20 days difference for the 100 mg dose of clomid. If they did not ovulate on 100mg, then the process repeats and another 20 days before they start 150mg. Therefore, the time to ovulation and pregnancy may be reduced, and hopefully pregnancy, by using the stair-step protocol. This method utilizes ultrasound monitoring for follicle development before increasing the dose of clomiphene citrate.
