Follicle-stimulating hormone (FSH), current suicidal ideation and attempt in female patients with major depressive disorder

Abstract

Current suicidal ideation and attempts are more commonly found in female patients with major depressive disorder (MDD) than in males. However, little is known about the relationship between activity of female reproductive hormones and suicide. The study population consisted of 490 female MDD patients of age ≥18. They were assessed by the Mini-International Neuropsychiatric Interview. At the same visit, we measured blood Follicle-Stimulating Hormone (FSH), Luteinizing Hormone (LH), estradiol, progesterone, Adrenocorticotropic Hormone (ACTH), cortisol, thyroid hormones, and prolactin. Blood FSH showed a significant difference among female MDD patients with suicide attempt, those with ideation, and those without within the previous month. Post-hoc analysis also showed that FSH was significantly lower in MDD patients with suicide attempt and ideation than those without, whereas other hormones showed no differences between those with and without attempt. FSH was negatively associated with current suicidality scores after adjustment for age and education years in all age groups. FSH was significantly lower in those with current suicide ideation or attempt than those without in age 45 years or under, but not in other age groups. In conclusion, blood FSH is significantly lower in female MDD patients with current suicide attempt or ideation than those without, especially in age 45 years or under.
