Azoospermia is defined as the complete absence of sperm in the ejaculate. It affects approximately 1% of the male population and accounts for a significant proportion of infertility cases. Azoospermia is categorized into obstructive and non-obstructive types.
Obstructive azoospermia occurs when sperm production is normal but blocked from entering the ejaculate due to ductal obstruction. Causes include congenital absence of the vas deferens, infections, trauma, or prior vasectomy. Non-obstructive azoospermia results from impaired sperm production within the testes and may be associated with genetic abnormalities, hormonal imbalance, or testicular failure.
Diagnosis requires at least two semen analyses confirming the absence of sperm. Hormonal evaluation, including follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone levels, assists in distinguishing between obstructive and non-obstructive causes. Scrotal ultrasound and genetic testing may also be indicated.
Treatment depends on the underlying cause. Microsurgical reconstruction may restore fertility in obstructive cases. For non-obstructive azoospermia, sperm retrieval techniques such as micro-TESE (microsurgical testicular sperm extraction) combined with intracytoplasmic sperm injection (ICSI) offer promising outcomes.
A multidisciplinary approach involving reproductive specialists, genetic counselors, and psychologists ensures erotic comprehensive patient care.
