Brief Summary
The objective of this application is to identify a pharmacologic agent which helps couples in whom the female partner ovulates regularly successfully obtain their goal of delivering a healthy child, whose use will result in low rates of multiple gestations. The central hypothesis is that, in infertile ovulatory women undergoing ovarian stimulation (OS) and intrauterine insemination (IUI), the use of aromatase inhibitors (AI) will stimulate the ovaries sufficiently to produce no reduction in the rate of pregnancy, while significantly reducing the numbers of multiple gestational pregnancies that result from stimulation with clomiphene citrate (CC) or follicle stimulating hormone (FSH). The rationale for the proposed research is that reduction of multiple pregnancy rates could significantly reduce maternal and neonatal morbidity and mortality, as well as the cost of healthcare for these individuals and society.

Outcome Measures
Primary Outcomes (1)
Multiple Gestation Rate Following Recruitment of Multiple Follicular Development With an AI, as Compared to CC and FSH.
Participants were followed for the duration of their treatment and, if pregnant through 6 weeks post-delivery, up to 66 weeks
Secondary Outcomes (3)
Rate of Pregnancy Obtained
Participants were followed for the duration of their treatment and, if pregnant through 6 weeks post-delivery, up to 66 weeks
Time to Pregnancy
Participants were followed for the duration of their treatment and, if pregnant through 6 weeks post-delivery, up to 66 weeks
Live Birth Rate
Participants were followed for the duration of their treatment and, if pregnant through 6 weeks post-delivery, up to 66 weeks
Study Arms (3)
Aromatase Inhibitors (AI)
ACTIVE COMPARATORA daily dose of 5 mg of the AI, letrozole, will be administered orally for five days starting on day three of the menstrual cycle. Future cycles can be started at 2.5-7.5 mg/d. FDA approval (IND) will be obtained.
Clomiphene Citrate (CC)
ACTIVE COMPARATORCC will be administered at a dose of 100 mg/d on cycle days 3-7. Future cycles can be started at 50-150 mg/d.
Follicle Stimulating Hormone (FSH)
ACTIVE COMPARATORA daily injection of 150 IU of FSH will be administered subcutaneously starting on day three of the menstrual cycle and continuing until the day of hCG administration. Dosage will be able to be increased or decreased 37.5-75 IU/d beginning cycle day 7. Future cycles can be started at doses ranging from 75-225 IU/d. The same type of FSH injections will be used.
Interventions
A daily dose of 5 mg of the AI, letrozole, will be administered orally for five days starting on day three of the menstrual cycle. Future cycles can be started at 2.5-7.5 mg/d. FDA approval (IND) will be obtained.
CC will be administered at a dose of 100 mg/d on cycle days 3-7. Future cycles can be started at 50-150 mg/d.
A daily injection of 150 IU of FSH will be administered subcutaneously starting on day three of the menstrual cycle and continuing until the day of hCG administration. Dosage will be able to be increased or decreased 37.5-75 IU/d beginning cycle day 7. Future cycles can be started at doses ranging from 75-225 IU/d. The same type of FSH injections will be used.
Eligibility Criteria
You may qualify if:
- Women ≥18 to ≤40 years of age, with one or more years infertility history, desirous of conceiving, regularly ovulating (defined as 9 or more menses per year), at initiation of participation.
- Normal uterine cavity and at least one open fallopian tube confirmed by hysterosalpingography (HSG), sonohysterography, or laparoscopy/hysteroscopy in the last three years preceding enrollment into the study. An uncomplicated intrauterine non-IVF pregnancy and uncomplicated delivery and postpartum course resulting in live birth within the last three years will also serve as sufficient evidence of a patent tube and normal uterine cavity as long as the subject did not have, during the pregnancy or subsequently, risk factors for Asherman's syndrome or tubal disease or other disorder leading to an increased suspicion for intrauterine abnormality or tubal occlusion.
- Evidence of ovarian function/reserve as assessed by day 3 (+/-2 days) FSH ≤12 IU/L within one year prior to study initiation.
- Normal or corrected thyroid function within one year of study initiation.
- Normal prolactin level within one year of study initiation.
- In general good health, not taking any medications which could interfere with the study (e.g., FSH, insulin sensitizers).
- Ability to have inseminations following hCG administration.
- Male partner with total motile sperm in the ejaculate of at least 5 million sperm, within one year of study initiation.
You may not qualify if:
- Undiagnosed abnormal uterine bleeding.
- Suspicious ovarian mass.
- Patients on oral contraceptives, depo-progestins, or hormonal implants (including Implanon). A two month washout period will be required prior to screening for patients on these agents. Longer washouts may be necessary for certain depot contraceptive forms or implants, especially when the implants are still in place. A one-month washout will be required for patients on oral cyclic progestins.
- Known 21-hydroxylase deficiency or other enzyme defect causing congenital adrenal hyperplasia.
- Type I or Type II diabetes mellitus, or if receiving antidiabetic medications.
- Known significant anemia (Hemoglobin \<10 g/dL).
- History of deep venous thrombosis, pulmonary embolus, or cerebrovascular event.
- Known heart disease (New York Heart Association Class II or higher).
- Known Liver disease (defined as AST or ALT\>2 times normal, or total bilirubin \>2.5 mg/dL).
- Known Renal disease (defined as BUN \>30 mg/dL or serum creatinine \> 1.4 mg/dL).
- History of, or suspected cervical carcinoma, endometrial carcinoma or breast carcinoma.
- History of alcohol abuse (defined as \>14 drinks/week) or binge drinking of ≥ 6 drinks at one time).
- Known Cushing's disease.
- Known or suspected adrenal or ovarian androgen secreting tumors.
- Allergy or contraindication to the treatment medications: AI, gonadotropins, CC or hCG.
