and here's the drum on clomiphene:

"Is clomiphene for you?"
Clomiphene can help you conceive if you ovulate irregularly or not at all, particularly if you have polycystic ovarian syndrome (PCOS). (If you have PCOS and this treatment doesn't seem to work for you, your doctor may also prescribe metformin, an insulin-sensitizing drug that can help you respond to clomiphene.) You might also take clomiphene (and other fertility drugs) before you undergo an assisted reproductive technology (ART) treatment such as in vitro fertilization (IVF), to encourage you to produce several eggs for the procedure.

Clomiphene can also help men with a hormonal imbalance (that originates in the pituitary gland or hypothalamus) linked to a low sperm count, or poor sperm quality or motility (its ability to move).
