| In all patients, ovarian follicles were matured by either a natural cycle or a clomiphene citrate cycle. |
| Two drugs, clomiphene and letrozole, are commonly prescribed to stimulate ovulation. |
| Some are given clomiphene to induce ovulation, but it doesn't always work. |
| An alternative to assisted reproductive technologies is empiric treatment with clomiphene citrate, although few convincing data show benefit. |
| At its simplest it involves the woman taking a drug called clomiphene for six days each month. |
