Azoospermia (Zero Sperm Count)
Azoospermia is the absence of sperm in the ejaculate, affecting 1% of men but accounting for 10-15% of male infertility cases.
Understanding Azoospermia
Azoospermia is diagnosed when no sperm are found in the ejaculate after centrifugation and microscopic examination. It's classified into two main types: obstructive (blockage preventing sperm release) and non-obstructive (impaired sperm production).
Key Facts
- Affects 1% of all men and 10-15% of infertile men
- 40% of cases are obstructive and potentially reversible
- 60% are non-obstructive with production issues
- Sperm retrieval success: 80-100% in OA, 40-60% in NOA
Causes & Classification
Obstructive Azoospermia (OA)
Sperm production is normal but blocked from reaching the ejaculate
Causes:
- • Congenital absence of vas deferens (CBAVD)
- • Infections causing scarring
- • Vasectomy
- • Ejaculatory duct obstruction
- • Trauma or surgical injury
Non-Obstructive Azoospermia (NOA)
Impaired sperm production in the testicles
Causes:
- • Genetic disorders (Klinefelter syndrome)
- • Y-chromosome microdeletions
- • Hormonal imbalances
- • Testicular failure
- • Radiation/chemotherapy damage
Comprehensive Diagnosis

Frequently Asked Questions
Is biological fatherhood possible with azoospermia?
Yes, in most cases. For obstructive azoospermia, sperm retrieval success rates are very high. For non-obstructive azoospermia, sperm can be found in about half of cases using micro-TESE. Retrieved sperm can be used with ICSI to achieve pregnancy.
What's the difference between obstructive and non-obstructive azoospermia?
Obstructive azoospermia means sperm are produced but can't reach the ejaculate due to blockages. Non-obstructive azoospermia indicates impaired sperm production. OA has better treatment outcomes than NOA.
How painful is sperm retrieval surgery?
Sperm retrieval is performed under anesthesia. Most men experience mild discomfort for 3-5 days post-procedure, manageable with oral pain medication. Micro-TESE requires 1-2 weeks of limited activity.
Can hormone therapy help with azoospermia?
Hormone therapy may help in specific cases of non-obstructive azoospermia caused by hormonal imbalances. Success rates vary from 10-40% depending on the underlying condition.
What are the risks of sperm retrieval?
Risks include bleeding, infection, pain, and testicular atrophy. Micro-TESE has lower complication rates than conventional TESE. Our complication rate is less than 2%.
