Female patients with classical galactosemia (galactose-1-phosphate uridyltransferase [GALT] deficiency) frequently suffer from premature ovarian failure, despite treatment with a galactose-restricted diet. Earlier research has suggested an association between heterozygosity for GALT mutations and early menopause. This study evaluates the effect of carriership for classical galactosemia on ovarian reserve and menopausal age. Proven female carriers of classical galactosemia were recruited via the Dutch Galactosemia Society. All 58 participants underwent a structured interview regarding fertility, smoking status, and menopause. To determine ovarian reserve, 42 premenopausal GALT carriers underwent ovarian antral follicle count (AFC) by transvaginal ultrasound and early follicular phase blood sampling for hormonal measurement of follicle-stimulating hormone (FSH), inhibin B, and anti-Müllerian hormone (AMH). These ovarian reserve parameters were compared with a cohort of proven fertile women (n = 166). The mean age at menopause in GALT carriers was 49.7 years, which is not different from the mean age at menopause in the general population in the Netherlands. There was no difference in FSH, inhibin B, and AMH levels or in the AFC (when corrected for age and smoking status) between 42 premenopausal GALT carriers and controls. The authors conclude that there is no evidence that GALT mutation carriership affects ovarian reserve or menopausal age.

Key Words: Galactosemia • menopause • anti-Müllerian hormone • ovarian reserve.
