Summary, etc. Although Klinefelter syndrome (KS) is common, it is rarely recognised in childhood, sometimes being identified with speech or developmental delay or incidental antenatal diagnosis. The only regular feature is testicular dysfunction. The postnatal gonadotropin surge (mini-puberty) may be lower but treatment with testosterone needs prospective studies. The onset of puberty is at the normal age and biochemical hypogonadism does not typically occur until late-puberty. Testosterone supplementation can be considered then or earlier for clinical hypogonadism. The size at birth is normal, but growth acceleration is more rapid in early and mid-childhood with adult height greater than mid-parental height. Extreme tall stature is unusual. The incidence of adolescent gynaecomastia (35.6%) is not increased compared with typically developing boys. It can be reduced or resolved by testosterone supplementation potentially preventing the need for surgery. Around two-thirds require speech and language therapy or developmental support and instituting therapy early is important. Provision of psychological support may be helpful to ameliorate these experiences and provide opportunities to develop strategies to recognise, process and express feelings and thoughts. KS boys are at increased risk of impairment in social cognition and less accurate in perceptions of social emotional cues. The concept of likely fertility problems needs introduction alongside the regular reviews of puberty and sexual function in adolescents. Although there is now greater success in harvesting sperm through techniques such as testicular sperm extraction, it is more successful in later adolescence than earlier. In-vitro maturation of germ cells is still experimental.
