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. SUBJECT AND 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. CONCLUSION: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%).
