Premature ovarian failure is defined as the cessation of ovarian activity before the age of 40 years. It is biochemically characterized by low levels of gonadal hormones (estrogens and inhibins) and high levels of gonadotropins (luteinizing hormone and follicle-stimulating hormone).
Our patient, a 22-year-old Caucasian woman under evaluation for infertility, had experienced secondary amenorrhea from the age of 18. No positive family history was noted regarding premature menopause. An examination of our patient’s karyotype showed the presence of a reciprocal translocation, apparently balanced, which had the X chromosome long arm (q13) and the 14 chromosome short arm (p12) with consequent karyotype: 46, X, t(X; 14)(q13;p12).
Our study has underlined that karyotyping is one of the fundamental investigations in the evaluation of amenorrhea. It highlighted a genetic etiology, in the form of a chromosomal abnormality, as the causal factor in amenorrhea.
