Subjects and Procedures
The sample comprised 20 male adolescents aged between 12 and 17 years who met the DSM-IV diagnostic criteria (American Psychiatric Association, 1994) for anorexia nervosa. All patients were attended at the Reference Unit for Eating Disorders of the Department of Child and Adolescent Psychiatry and Psychology of the Hospital Clinic Universitari in Barcelona between 1997 and 2000. Patients in this unit can be treated as inpatients, as outpatients, or as day hospital attenders, and the severity of
General Characteristics
The mean age of anorexic patients at the first consultation was 15.4 years (SD = 1.4). Mean body mass index was 16.2 (SD = 1.2) and mean percentage of weight loss was 21.5% (SD = 4.7). Mean period between the onset of the disorder (i.e., since the first weight loss) and first contact with the team was 12.5 months (SD = 6.4). Mean testosterone value was 392.0 ng/dL (SD = 274.4); alkaline phosphatase, 252.6 U/L (SD = 149.8); and IGF-I, 307.6 ng/mL (SD = 166.3). All patients were restrictive type.
DISCUSSION
The first conclusion of this study was that the percentage of male adolescents with anorexia nervosa with reduced BMD was comparable with the figures recorded for female adolescent patients. As in the case of female adolescent patients, BMD in male adolescent anorexic patients may be within the normal range, but in approximately 35% the BMD z score at the lumbar spine and at the femoral neck was less than −1, thus compatible with osteopenia. In female adolescent patients the percentage varies

Anorexia nervosa and bone
2018, Current Opinion in Endocrine and Metabolic ResearchCitation Excerpt :For both groups, changes in bone mass may occur relatively rapidly, often within the first year of disease [47]. Moreover, duration of illness is associated with lower BMD in both male [48] and female adolescents [49] and women [5], and more impaired bone microarchitecture in females [19], suggesting that bone loss continues throughout the course of the illness [49]. The energy deficit associated with nutritional deprivation in females with AN often results in hypothalamic amenorrhea, which contributes to impaired skeletal integrity (Figure 1).
Endocrine consequences of anorexia nervosa
2014, The Lancet Diabetes and EndocrinologyCitation Excerpt :In fact, areal BMD Z scores frequently continue to decrease even after weight gain.127 Low BMD is also observed in adolescent boys with anorexia nervosa72,128 but, in contrast to girls, sites of predominantly cortical bone, such as the hip, are involved to a greater extent than the spine. The proportions of boys with anorexia nervosa who have Z scores lower than −1·0 at the femoral neck and spine are 65% and 50%, respectively, compared with 18% and 24% in normal-weight boys.72
Normal Inhibin B Levels Suggest Partial Preservation of Gonadal Function in Adult Male Patients with Anorexia Nervosa
2012, Journal of Sexual MedicineCitation Excerpt :To date, few articles indicated low levels of FSH, LH, and testosterone. These studies included a limited number of subjects with important interpatients' hormonal variability [6-8]. Therefore, the precise impact of undernutrition on gonadotropic axis is a major issue to clarify in men with AN.
