Low hormones: The most common reason for your symptoms is low estrogen level. The amount of estrogen you are taking is a tiny fraction of what normally would be produced by your ovaries. Low estrogen is the number one cause for decreased libido. If your symptoms do not resolve with an increase in your dose of estrogen, it may be necessary to add testosterone to your hormone replacement.

Hormones: Your estrogen level is probably low, and needs to be adjusted. You also may need some testosterone, as well. A blood test can measure each of those hormone levels. Bioidentical hormones would be a great option, since the Premarin (conjugated estrogens) is not working well.

Hysterectomy: Your age also plays a role in your symptoms. If you are in the peri-menopausal age group you may be deloping symptoms of low estrogen and testosterone. A total hysterectomy without removal of both ovaries usually do not aggravate the natural course of the condition. You may want to have your thyroid level and growth hormone levels checked. Bioidentical hormones are great alternatives to premarin (conjugated estrogens).
