Results from twin, family, and adoption studies all suggest that general intelligence is highly heritable. Several studies have shown lower premorbid intelligence in individuals before the onset of both mood disorders and psychosis, as well as in children and adolescents at genetic high risk for developing schizophrenia.

The functional role of the GGN repeat in the human androgen receptor gene is unknown, although mutations in this region have been found in patients with inter-sex conditions. We have investigated the prevalence of GGN mutations in the androgen receptor in the Swedish population and their relation to male reproductive function. A physical examination and semen analysis was carried out in 223 men...
