Male Reproductive Disorders Quiz

Cryptorchidism

• Failure of testicles to descend into the scrotal sac.
• Testicles typically form in the abdomen, then descend into the scrotum as the fetus develops.
• Most common congenital male reproductive abnormality
• Affects approximately 1% of infant males.

Orchitis

• Inflammation of the testicle
• Causes:
  • Chlamydia trachomatis, Neisseria gonorrhoeae: Common in young adults, may lead to sterility but not affect libido.
  • Escherichia coli, Pseudomonas: Usually seen in older adults, related to urinary tract infections.
  • Mumps virus: Primarily affects teenage males; may cause infertility and testicular inflammation.
  • Autoimmune response: Characterized by granulomas in the seminiferous tubules.

Testicular Torsion

• Twisting of spermatic cord; obstructing blood flow through veins.
• Results in congestion and hemorrhagic infarction (tissue death).
• Often from congenital issues of testicular attachment to the scrotum.
• Characterized by sudden testicular pain and lack of cremasteric reflex.

Varicocele

• Enlarged spermatic veins, impairing drainage.
• Causes a "bag of worms" appearance in the scrotum.
• Commonly on the left side since the left testicular vein drains into the left renal vein, and the right testicular vein drains directly into the inferior vena cava.
• Associated with left-sided renal cell carcinoma (RCC); RCC can often invade the renal vein.
• A significant contributor to male infertility.

Hydrocele

• Fluid collection within the tunica vaginalis.
• Tunica vaginalis is a membrane that covers the testicle and internal surface of the scrotum.
• Can be due to incomplete closure of the process vaginalis (infants) or blockage of lymphatic drainage (adults).
