The main purpose of this study is to test the effectiveness of nimodipine in preventing a luteinizing hormone (LH) surge in women undergoing ovulation induction with clomiphene citrate. It is important to prevent the premature LH surge in controlled ovarian stimulation to allow adequate recruitment of follicles, proper maturation of a dominant follicle before ovulation, and effectively time insemination with semen to allow fertilization of a mature egg to occur.
The investigators are also conducting this study to determine medication side effect profile (including lightheadedness or dizziness from low blood pressure or rapid heart rate, headache, and nausea), patient treatment compliance, and clinical pregnancy (positive pregnancy test and ultrasound evidence of fetal heart rate). Finally, LH and follicle stimulating hormone (FSH) serum levels will be measured to determine effect of nimodipine on these hormones.
As a calcium channel blocker, nimodipine has been shown to block calcium mediated release of gonadotropin releasing hormone in animal and preliminary human studies. The investigators hypothesize that nimodipine, a calcium channel blocker, will prevent or delay the LH surge during controlled ovarian stimulation cycles using clomiphene citrate in subfertile patients undergoing assisted reproduction with intrauterine insemination (IUI).
After enrollment, subjects will be randomized to Placebo Comparator or Active Comparator. All subjects will receive Clomid 100 mg for 5 days for the purpose of ovarian follicle recruitment. Intervention will be initiated once ovarian follicle maturation has been documented (≥1 ovarian follicle size of ≥ 17mm) and the absence of a premature LH surge has been confirmed - this will be classified as intervention day 0. Subjects will receive their assigned comparator (Placebo or Active) according the schedule below:

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Placebo | Placebo Comparator | All subjects in both arms will receive Clomid 100 mg tablets by mouth for 5 days prior to receiving either placebo comparator or active comparator. Placebo comparator subjects will receive 8 total doses of liquid placebo orally 4 times a day for 8 total doses in pre-filled liquid placebo containing syringes |
|
| Nimodipine | Active Comparator | All subjects in both arms will receive Clomid 100 mg tablets by mouth for 5 days prior to receiving either placebo comparator or active comparator. Active comparator subjects will receive Nimodipine 30mg liquid orally 4 times a day for 8 total doses in pre-filled syringes |

| LH Surge | Compare the change between placebo treated and nimodipine treated patients by the presence or absence of an LH surge on intervention Day 1 and Day 2. LH surge will be determined by serum LH levels at least two times the baseline serum LH (baseline serum LH = (cycle day 3 serum [LH] + cycle day 7 serum [LH])/2). | 7 days |
