title: Reproductive function in men affected by X-linked adrenoleukodystrophy/adrenomyeloneuropathy.
abstract: BACKGROUND
  X-linked adrenoleukodystrophy (X-ALD) is the most frequent, severely neurodegenerative, clinically heterogeneous peroxisomal disorder, the signs of which are a consequence of myelin, adrenal cortex, and testes impairment.
  
  
  OBJECTIVE
  We studied testosterone, LH, and FSH levels in X-ALD/adrenomyeloneuropathy (AMN) patients. We evaluate the ability to procreate of these patients by analysis of pedigree and family screening by detection of very long-chain fatty acid (VLCFA) levels.
  
  
  METHODS
  Seventeen patients with X-ALD/AMN (16 with AMN and one asymptomatic) aged 24-48 (mean±S.D., 34.7±5.9) years, were identified based on the clinical picture, magnetic resonance imaging, and the presence of increased serum VLCFA levels. Nine X-ALD/AMN patients' daughters, mean ages ±S.D.=7.7±3.8 years, were identified as heterozygote by elevated VLCFA levels. Serum VLCFA levels were determined as ester derivatives by a gas chromatography method. Serum testosterone, LH, and FSH levels in X-ALD/AMN patients were detected by IRMAs.
  
  
  RESULTS
  Serum testosterone levels were at the lowest levels of normal range but serum LH and FSH concentrations were increased in 57.1 and in 42.9% of X-ALD/AMN patients respectively. Among the 11 investigated of X-ALD/AMN married adult men, nine had produced offspring, a total of 13 children. All patients' daughters showed elevated serum VLCFA at heterozygote levels.
  
  
  CONCLUSIONS
  In this study, we report that in a group of X-ALD/AMN married adult men, we did not find a significant decrease in fertility compared with the Polish population (18.2 vs 15%).
