Section 1: Introduction

Semaglutide, a medication initially approved for the treatment of type 2 diabetes, has gained attention for its potential benefits in weight management and cardiovascular health. Its role as a glucagon-like peptide-1 (GLP-1) receptor agonist enables it to regulate blood sugar levels by enhancing insulin secretion, suppressing glucagon secretion, and slowing gastric emptying. Beyond its primary use, semaglutide’s effects on body weight reduction have led to its approval for treating obesity, offering a new tool in the fight against this global health issue.

Parallel to the exploration of semaglutide’s benefits, there’s a growing interest in understanding its interactions with key hormones in the body, notably estrogen, progesterone, and testosterone. These hormones play vital roles in regulating various physiological processes, including metabolism, reproductive health, and secondary sexual characteristics. Estrogen, primarily considered a female hormone, supports reproductive health and influences body fat distribution, bone density, and skin health. Progesterone, another crucial hormone in female reproductive health, is involved in the menstrual cycle and pregnancy. Testosterone, often labeled as a male hormone, is essential in both males and females for maintaining muscle mass, bone density, and libido.

The relationship between semaglutide and these hormones is of particular interest for several reasons. Firstly, the obesity epidemic has been linked to hormonal imbalances, suggesting that weight management strategies could benefit from a hormonal perspective. Secondly, patients undergoing hormone replacement therapy (HRT) for various reasons, including menopause management, transgender hormone therapy, and treatment of hormonal deficiencies, might be affected by semaglutide’s influence on these hormones.
