Is there an easy way for a premenopausal woman to fix the problem of no sex drive, or decreased drive?

You need a Dx!: Depending on the causes treatments vary. Hormonal issues include elevated prolactin, a decreased thyroid function, or low testosterone (which must be checked mid-cycle). However, many issues may be psychological. This must be sorted out. In todays 2-working couple homes, women still typically do more household chores and are simply tired!

Easy? No but . . .: Dr. Namey is absolutely correct. You need a diagnosis before attempting to fix the problem. My perspective is that there is no "easy" solution that fits everyone. However, it's possible to find an individualized sol'n after reviewing stress (relationship, money, family, friends, etc), substance use (tobacco, alcohol, illicit stuff), medications, health & finally testosterone level for causes.
