Steroidogenesis is the biological process by which steroids are produced from cholesterol in the body. This process occurs primarily in the adrenal glands, ovaries, and testes. It involves a series of enzymatic reactions that convert cholesterol into various steroid hormones, including cortisol, testosterone, and estrogen. These hormones play crucial roles in regulating metabolism, immune response, and reproductive functions. The process of steroidogenesis is tightly regulated by hormones such as adrenocorticotropic hormone (ACTH) and luteinizing hormone (LH). Disruptions in steroidogenesis can lead to hormonal imbalances and various health issues, including Cushing's syndrome and polycystic ovary syndrome (PCOS). Understanding this process is essential for diagnosing and treating related disorders.
