Similarity of female central (hypogonadotropic) hypogonadism and postmenopause.

OBJECTIVES

Central (hypogonadotropic) hypogonadism in women could be a cause of persistent amenorrhea and hypoestrogenemia as observed in postmenopause. This study aimed to compare the clinical, hormonal and biochemical features in women with non-physiological (central hypogonadism) and physiological (postmenopause) hypoestrogenemia.

METHODS

A total of 161 young women, median age 24.9 years (interquartile range (IQR) 21.2; 30.5) with central hypogonadism (with isolated hypogonadotropic hypogonadism, n = 76, and with hypopituitarism, n = 85), 53 healthy young women, median age 23.9 years (IQR 23.1; 28.0) and 50 healthy postmenopausal women, median age 56.0 years (IQR 53.1; 58.5), were examined. Psychoemotional, neurovegetative and urogenital symptoms, sex steroid levels, parameters of lipid and mineral metabolism were evaluated.

RESULTS

In young women with central hypogonadism, the frequencies of psychoemotional, neurovegetative and urogenital complaints differed significantly from those in healthy young women and were similar to those in postmenopausal women. Concentrations of estradiol, testosterone, dehydroepiandrosterone sulfate, parameters of lipid and mineral metabolism as well as quality of life in women with central hypogonadism were not typical of healthy young women but were similar to those of postmenopausal women of middle/old age.

CONCLUSIONS

Despite the young age of women with central hypogonadism, clinical, hormonal and biochemical abnormalities were similar in many aspects to those in postmenopausal women at middle/old age. These revealed features could be considered as signs of premature aging in young amenorrheic women with low gonadotropin levels.
