CONTEXT: Endothelial dysfunction and altered psychological measures have been identified in women with functional hypothalamic amenorrhea (FHA). Estradiol (E2) replacement, a known vasodilator, may potentially reverse vascular dysfunction and improve psychological health.
OBJECTIVE: To evaluate 12 weeks of physiologic E2 replacement on vascular, hormonal, and psychological outcomes in women with FHA.
METHODS: A randomized, double-blind, placebo-controlled trial was conducted in 29 women with FHA with 0.1 mg/day transdermal E2 (n = 14) or placebo patch (n = 15) twice weekly for 12 weeks. FHA was defined as amenorrhea ≥3 consecutive months, E2 < 50 pg/mL, follicle-stimulating hormone (FSH) and luteinizing hormone (LH) <10 mIU/L, LH:FSH <1, excluding other etiologies. Endothelial dysfunction (reactive hyperemic index ≤ 1.67) was assessed, as were hormonal and psychological measures.
RESULTS: Women with FHA had a mean age of 26.2 ± 6.3 years, body mass index of 21.5 ± 3.3 kg/m2, with 63% being non-Hispanic White. Baseline characteristics did not differ between groups. After 12 weeks, E2 levels were significantly higher in the E2 group (112.0 vs 36.5 pg/mL, P = .0002). However, there were no significant differences in vascular, hormonal, or psychological outcomes between E2 and placebo groups at week 12. Cortisol levels showed a near-significant decrease in the E2 group compared to an increase with placebo (-.4 vs 3.1 µg/dL, P = .05).
CONCLUSION: In women with FHA, 12 weeks of transdermal E2 increased serum E2 levels but did not improve vascular or psychological health measures. Further studies with larger sample sizes and longer follow-up are needed to explore the long-term effects of E2 therapy on cardiovascular and mental health outcomes in this population.
