When Testosterone disappears completely from the body, there is a gradual change, which takes place over a week or so. The first noticeable symptom after the decline begins in this case is bad mood. Things deteriorate from there. Depression, rage and irrational thought begin to pervade daily life. It is only when there is almost a complete absence of Testosterone that hot flashes/flushes begin, which take about three weeks to appear. It is a dangerous time for an individual.

However, not many people suffer the instant removal of Testosterone supply. Most have a slowly declining production, causing a mystery to develop as to why a person has changed for the worse. The symptoms described above, tend to manifest very slowly, perhaps with lethargy and loss of libido preceding the bad moods.

In most cases, the condition remains undetected until it is too late. Too late to stop life-changing decisions. Relationships, jobs and quality of life having been damaged long before.

If a child is born with this condition, development will be slower, concentration may be lacking and the ability to compete with peers becomes affected. The child is at risk of bullying and victimisation as peers mature whilst they languish, without a hair to be seen in important places.
