Lack of Concentration
Another symptom of hypogonadism would be brain fog. You might have been a human calculator in the past, but now you struggle to calculate even the simplest of arithmetic. Little details will be hard to grasp. This then creates careless mistakes that worsen your mood. Since lack of concentration is considered one of the less obvious symptoms of low-T, if you are experiencing brain fog along with other symptoms on this list, you should schedule an appointment with your doctor as soon as you can for testing.
The good news is that men who experience poor concentration due to low testosterone often have relief in as little of 4 weeks of hormone replacement therapy.
