High PSA Levels May Indicate

• Prostate Cancer – Higher PSA levels may suggest malignancy, but further testing (e.g., biopsy) is required for confirmation.
• Benign Prostatic Hyperplasia (BPH) – Non-cancerous prostate enlargement can elevate PSA.
• Prostatitis – Inflammation or infection of the prostate may temporarily raise PSA levels.
• Recent Ejaculation or Physical Activity – Activities like cycling or prostate stimulation can cause transient PSA increases.

PSA and Age Considerations

• Expected in Healthy Prostates – Healthy, younger adult males generally have low PSA levels.
• Age Considerations – PSA naturally increases with age, so age-adjusted ranges are essential for interpretation.

Reproductive (Hypothalamic–Pituitary–Gonadal) Axis 

• Follicle-Stimulating Hormone (FSH): Regulates gonadal function and gamete production.
• Luteinizing Hormone (LH): Stimulates gonadal hormone production, including triggering testosterone synthesis.
• Prolactin: Primarily known for its role in lactation, it also modulates reproductive function.
• Testosterone: The primary androgen produced in response to pituitary signals, essential for sexual development and reproductive function.
• Somatotropic Hormone (Growth Hormone, GH):
  Although primarily responsible for growth and metabolism, it indirectly enhances reproductive health by optimizing overall tissue function

These hormones provide a comprehensive insight into the endocrine mechanisms governing reproduction. FSH and LH regulate gonadal function and testosterone production, Prolactin modulates various reproductive processes, and GH indirectly supports reproductive health by influencing overall tissue function.

Prostate

• Acid Phosphatase:
  Historically used as a marker for prostate pathology before more sensitive tests were available.
  
  
• Prostate Specific Antigen (PSA):
  Currently the primary tool for screening and monitoring prostate cancer due to its high sensitivity.
  
  

Both markers are integral in evaluating prostate tissue, with acid phosphatase playing a historical role and PSA serving as the cornerstone of modern prostate cancer detection and management.
