From mile 2.80 on the Grays Peak Trail, the Torreys Peak Trail begins and traverses across the North Slope of Grays Peak. After .25 miles the trail turns on two short switchbacks. A snowfield often lingers on the North Slopes of Grays between the switchbacks and the saddle.
Normal Levels. According to MedlinePlus.com, a normal testosterone level for an adult female is 20 to 80 nanograms per deciliter. Testosterone levels fluctuate during the day, but are highest in the morning so blood should be drawn as close to the morning as possible. Some laboratories may have different normal testosterone ranges.
Testosterone levels between 300 ng/dL and 1000 ng/dL are generally considered in the normal range. The brain and the testes work together to keep testosterone in this range. When levels of testosterone are below the normal range, the brain signals the testes to make more. Hypogonadism can occur when a man has low testosterone levels which can be caused by certain medical conditions causing a problem with the testes and/or parts of the brain that regulate the testes. 2  Today men with hypogonadism may be able to raise their testosterone levels and keep them in the normal range.
