Treatment Options for Testicular Atrophy Associated with Azoospermia

For men with testicular atrophy and azoospermia, surgical sperm retrieval techniques such as microdissection testicular sperm extraction (micro-TESE) offer the best chance for successful fertility outcomes, regardless of testicular volume. 1, 2

Diagnostic Evaluation

Before proceeding with treatment, a thorough diagnostic workup is essential:

  • Hormonal evaluation: Measure testosterone, FSH, and LH levels

    • FSH >7.5 IU/L indicates 5-13 times higher risk of abnormal semen quality
    • FSH >12.1 IU/L has positive predictive value >0.7 for subfertility 3

  • Imaging: Ultrasound with Doppler to assess testicular size, echotexture, and blood flow 3

  • Semen analysis: Confirm azoospermia with pelleted specimen 4

  • Determine type of azoospermia:

    • Obstructive azoospermia: Normal FSH, normal testicular volume
    • Non-obstructive azoospermia (NOA): Elevated FSH, testicular atrophy 5

Treatment Algorithm Based on Azoospermia Type

1. Obstructive Azoospermia

  • Ejaculatory duct obstruction (EDO):

    • Transurethral resection of ejaculatory ducts (TURED) if confirmed by TRUS or MRI findings
    • Imaging findings suggesting EDO: seminal vesicle diameter >15mm, ejaculatory duct caliber >2.3mm, dilated vasal ampulla >6mm, prostatic cysts 1

  • Surgical sperm retrieval options:

    • Epididymal sperm retrieval (avoid if future reconstruction might be pursued)
    • Testicular sperm retrieval (TESA or TESE)
    • Both methods have similar fertilization, pregnancy, and live birth rates 1

2. Non-obstructive Azoospermia with Testicular Atrophy

  • First-line treatment: Microdissection testicular sperm extraction (micro-TESE)

    • Success rate is approximately 55-56% regardless of testicular volume
    • Even men with severe testicular atrophy (≤2ml) have similar sperm retrieval rates to those with larger testes 2
    • Micro-TESE is 1.5 times more effective than non-microsurgical TESE 1

  • Hormonal manipulation (limited evidence, may be tried before surgical intervention):

    • Selective estrogen receptor modulators (SERMs)
    • Aromatase inhibitors
    • Gonadotropins (hCG, FSH) 1, 3

  • Important: Avoid testosterone monotherapy in men desiring fertility as it suppresses spermatogenesis 1, 3, 6

Special Considerations

Younger Men with Klinefelter Syndrome

  • Higher sperm retrieval rates (81.8%) in men <30 years with Klinefelter syndrome and small testes
  • Age is the most significant factor affecting sperm retrieval success in men with severe testicular atrophy 2

Assisted Reproductive Technologies

  • After successful sperm retrieval, intracytoplasmic sperm injection (ICSI) is required
  • IVF with ICSI offers approximately 37% live delivery rate per initiated cycle
  • Clinical pregnancy rates of 47-55% have been reported after successful sperm retrieval 1, 2

Lifestyle Modifications

  • Weight management: Obesity is associated with reduced fertility 3
  • Smoking cessation: Smoking is associated with reduced fertility 3
  • Moderate alcohol consumption: Excessive alcohol is associated with lower semen volume 3
  • Avoid excessive heat exposure to the testes 3

Common Pitfalls to Avoid

  • Don't assume infertility is irreversible: Even men with severe testicular atrophy and markedly elevated FSH can have successful sperm retrieval in 24-30% of cases 4, 7

  • Don't delay testicular biopsy: Men with azoospermia and elevated FSH should still undergo testicular biopsy if ICSI is an acceptable approach 4

  • Don't use testosterone replacement: Exogenous testosterone provides negative feedback to the hypothalamus and pituitary, inhibiting gonadotropin secretion and potentially worsening spermatogenesis 1, 6

  • Don't exclude men from micro-TESE based on testicular size alone: Severe testicular atrophy should not be a contraindication to micro-TESE 2
