Hormones play an essential role in regulating reproductive health, fertility, and overall hormonal balance in both men and women. Among the most critical hormones involved in fertility are Anti-Müllerian Hormone (AMH), Follicle-Stimulating Hormone (FSH), Thyroid-Stimulating Hormone (TSH), Luteinizing Hormone (LH), and Testosterone. Understanding these hormones is vital for anyone dealing with fertility issues, as they can help diagnose problems related to ovarian reserve, sperm production, and hormone imbalances.
