Testicular function includes testosterone secretion and sperm formation. Low testosterone or the medical term commonly used ‘Hypogonadism’ is diagnosed when any of those functions is hindered, but this term is commonly attributed to states of testosterone deficiency. Brain glands (Hypothalamus and pituitary glands) release the first signal to testosterone secretion through the Luteinizing Hormone (LH), conveying the message to the testes; and if properly functioning, each testis obeys and responds by secreting testosterone hormone from group of specialized cells called leydig cells. Testosterone has many functions including (but not limited to) the

following:
• Supports the machinery of sperm formation inside the testes.
• Essential for most of spermatic functions including the integrity of sperm DNA, motility and fertilizing capacity.
• Plays an important role in male sexuality and libido (sexual drive).
• Essential for penile growth and health, making it crucial for sexual and erectile function.
• Enhances the metabolic functions of the body and augment fat burning.
• Being an anabolic steroid, it enhances muscular growth and repair.
• Maintains bone growth and integrity.
