[Hypergonadotropic amenorrhea (WHO III) as osteoporosis risk].

In 21 patients, suffering from amenorrhoeic hypergonadotropic ovarian insufficiency (age 27 +/- 3 years [FSH: 43 +/- 10, LH: 40 +/- 8]), the bone density was measured by single-photon densitometry (SPA), before starting a hormonal replacement therapy with oestrogen/progesterone. Every 5 months, the trend in bone density change was measured in all cases. The bone density before hormonal treatment was lower in the WHO III-group (1.36 +/- 0.21 g/cm; 1.09 +/- 0.26 g/cm2) than in the age-matched group (1.57 +/- 0.21 g/cm; 1.28 +/- 0.31 g/cm2). Bone density increased after hormonal therapy (p less than 0.05). These results point to the necessity of hormonal replacement therapy in cases of WHO III.
