A study of premature ovarian failure in Turkish women.

The parameters that could be responsible for or could be the end results of the premature ovarian failure were evaluated in 100 patients and compared with the same parameters of a control group consisting of 30 ovulatory healthy women with regular menstrual cycles. The incidence of premature ovarian failure was 6.6%. The mean age of the premature ovarian failure group was 39.2 +/- 4.1 years (range 30-58) whereas this was 45.6 +/- 3.1 years (range 39-52) for the control group. The mean menopausal age was 4.0 +/- 4.3 years (range 1-30). The prevalence of being a widow, divorcee or single was high in the premature ovarian failure group (p < 0.01). Of the hormonal and metabolic parameters, thyroid-stimulating hormone (TSH) and high-density lipoprotein (HDL) levels showed significant differences between the two groups (p < 0.01 and p < 0.05, respectively) and of the parameters reflecting bone metabolism, alkaline phosphatase levels showed a significant difference (p < 0.05). The bone mineral densitometric measurement values were lower in the premature ovarian failure group (p < 0.05). Because premature ovarian failure is not a rare disorder and because the patients have an early estrogen deficiency we concluded that, whatever the etiologic factor, hormone replacement therapy needs to be given as early as possible.
