I am a 25 y/o f, off yaz (drospirenone and ethinyl estradiol) 5 months ago, labs show testosterone <20. exp fatigue, weight gain, no libido, irritable. dr says level is normal. 2nd opinion ?

Another opinion: The measure that really matters is the free testosterone. Often this is not the reference value. It is altered by the amount of sex-binding hormone(protein) available. 20 in most labs would be low. Classic symptoms are: diminished libido, lack of vitality, inability to build muscle mass with exercise, depression, and decline in memory. Consider bio-identical hormone replacement.

Agree: Testosterone level is normal. Hypothyroidism, depression, anemia are among some possible causes of your symptoms.

Low: Yaz (drospirenone and ethinyl estradiol) can bind up free testosterone by increasing sex hormone binding. Yet, this total t is low to me. Remember, lab values represent the 95% confidence interval (or bell curve). To be abnormal, you have to reach a low that less than 2.5% of people would have in that lab's population of values. You are better off near the middle & for most women & their libido, near the top of the normal range.
