Objective: The aim of this study was to investigate serum lipid and hormone levels in women with premature ovarian failure (POF) and compare them with those of healthy women of similar age.
Methods: We measured fasting total cholesterol (TC), triglyceride, low-density lipoprotein (LDL), high-density lipoprotein, estradiol (E2), follicle-stimulating hormone (FSH), progesterone, and testosterone levels in 47 women with POF not using any hormone therapy and 60 healthy women of the same age range not using oral contraceptives or any other hormonal medication.
Results: There were no statistically significant differences between the groups in terms of age, body mass index (BMI) and smoking status (P = 0.054, 0.250, and 0.656, respectively). The mean E2 levels of the POF and control groups were 27.9 ± 2.3 and 87.8 ± 75.2 pg/mL, respectively (P < 0.001). Women with POF presented with significantly higher TC and LDL levels (P = 0.006 and 0.040, respectively). However, no difference was found between the groups with regard to triglyceride and high-density lipoprotein levels (P = 0.128 and 0.062, respectively). We determined that there was a significant negative correlation between E2 and TC levels (r = −0.291, P = 0.047) in the POF group. However, no correlation could be identified between E2 and lipids in the control group. Likewise, no correlation was present between FSH and lipids in both groups. We divided the control group according to basal FSH level. Group A consisted of the women with a serum FSH level lower than 7 IU/L, and group B consisted of the women with a serum FSH level of 7 IU/L or higher. There was no difference between the groups in age, body mass index, E2 concentration, and smoking status. The FSH level of group A was significantly lower than that of group B (P < 0.001). We found no difference between groups A and B with regard to lipid levels.
Conclusions: Higher TC and LDL levels in women with POF compared with the control group suggest that estrogen deprivation in women with POF leads to unfavorable lipid changes.
