Fig. 4. Hormone signaling. Interaction diagram of the physiological processes regarding the action of E2 and P4 on glucose metabolism (focused on insulin secretion in β-cells, glucose uptake in body tissues, and glucose storage in the liver). The left side shows the feedback loop from the HPO axis, with the Anti-Müllerian Hormone (AMH), E2 and P4 produced in and secreted by the ovaries, the Gonadotropin-releasing hormone (GnRH) by the hypothalamus and the Follicle-Stimulating Hormone (FSH) together with the Luteinizing Hormone (LH) produced in and secreted by the Pituitary. The right side is explained in Fig. 3. Pointing arrows are promoting effects, and flat-ended lines represent inhibitory effects.

New paper: How do hormonal changes during the menstrual cycle affect glucose regulation?

A new study by Carolina Ramírez Mazo, Lina Gómez-Echavarría, Laura Lema-Pérez, and Susanna Röblitz presents the first mathematical model to describe how hormonal fluctuations during the menstrual cycle influence glucose-insulin dynamics. The model integrates the effects of estradiol and progesterone on insulin sensitivity, insulin secretion, and β-cell maintenance, providing new insights into the complex interactions between reproductive hormones and metabolism. The findings contribute to a better understanding of women’s physiology and may support future research on diabetes and metabolic health in women.

The study, A physiologically based mathematical model describing estradiol and progesterone actions on glucose-insulin dynamics throughout the menstrual cycle, was published in the Journal of Theoretical Biology.
