The purpose of this study is to compare the length of time to achieve ovulation and pregnancy with a traditional protocol administration of clomiphene citrate versus a stair step administration.
Our hypothesis is by using a stair-step approach in which a period is not induced between administrations of escalating doses of clomiphene citrate, the time to ovulation and pregnancy may be reduced.
|Condition or disease||Intervention/treatment||Phase|
|Ovulatory Dysfunction Anovulation Ovulation Induction||Drug: clomiphene citrate||Phase 3|
The traditional administration of clomiphene citrate for ovulation induction involves taking clomiphene citrate for 5 days. If ovulation does not occur within 14 days, a progestin pill (such as Provera) is prescribed for 10 days to induce a period (which normally occurs within 1 week of stopping the pill). Then a higher dose of clomiphene citrate will be prescribed.
The stair-step administration of clomiphene citrate for ovulation induction also involves taking clomiphene citrate for 5 days. In contrast, if ovulation does not occur within 7-9 days, a progestin pill (such as Provera) would NOT be taken to induce a period. The dose of clomiphene will then be increased. Therefore, this would do away with the 10 days of taking the progestin pill, and also do away with waiting for a period (usually 3 to 7 days) for a total of up to a 20 day difference between clomiphene citrate dosing cycles.

Active Comparator: Traditional Administration
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.
Drug: 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.
Other Name: Clomid
Experimental: Stair-Step Administration
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.
Drug: 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, a blood draw (to test progesterone level) will be done. Increased dose of clomiphene citrate for 5 days starting that day. A repeat transvaginal ultrasound in one week to determine if there is a dominant follicle. This process will be repeated at increased doses of clomiphene citrate (100 mg and 150 mg) until a dominant follicle(s) is present.
Other Name: Clomid
- Time to Ovulation With Each Protocol [ Time Frame: 5 years ]We hypothesized that time to ovulation would be shorter with stair-step protocol vs. traditional.
- Rate of Ovulation [ Time Frame: 5 years ]Rate of ovulation with each dose of clomid within each protocol
- Delivery Outcomes [ Time Frame: 5 years ]Proportion of participants that delivered a baby based on which protocol they were randomized to.
