Objective:
To assess the associations between serum stress-related hormones (cortisol and cortisone) at one month postpartum and AMH levels at 4- and 10-year follow-ups.
Methods:
In a subset of 107 postpartum mothers enrolled in the PROGRESS cohort (at a mean age of 29.5 years), we measured serum cortisol and cortisone at one month postpartum via untargeted metabolomics. At 4- and 10-year follow-ups, we measured serum AMH levels. Serum cortisol, cortisone, and the cortisol-to-cortisone (F/E) ratio were analyzed both as continuous variables and as tertiles. The association between serum stress hormones and log2-transformed AMH levels was assessed using multivariable linear regression.
Results:
The serum cortisol and F/E ratio showed a weak and inverse association with AMH concentration at the 4-year follow-up. However, at the 10-year follow-up, each unit increase in the F/E ratio was associated with a 45% reduction in AMH levels (β = -0.60, 95% CI: -1.13; -0.07). In addition, when repeated time points were considered in the model, each unit increase in the F/E ratio was associated with a 32% reduction in AMH levels (β = -0.38, 95% CI: -0.75; -0.01). The analysis by tertiles of serum cortisone showed a dose-response relationship with AMH levels at the 10-year follow-up, while the F/E ratio was only associated in the highest tertile at the 4- and 10-year follow-ups, including when considering the model with repeated time points.
Conclusion:
Our findings suggest that a higher F/E ratio is associated with a lower AMH level, especially in mothers in the highest tertile of serum stress hormone levels. Our results support the role of stress hormone imbalance in ovarian aging.

01:24Gonadal and Placental Hormones
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair...
01:31Hormones of the Adrenal Glands
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and...
01:22Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

01:30Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
