Azoospermia is defined as the complete lack of sperm in the ejaculate. It occurs in 5% of infertile men. If this is the case, then one or both of two conditions may be present (“causes”): There is a problem with sperm production. There is a blockage such that sperm production, although normal, cannot reach the ejaculate.
Treatments for low sperm count include:
Surgery. For example, a swelling of the veins that drain the testicle (varicocele) can often be surgically fixed or an obstructed vas deferens tube repaired.
Treating infections. Antibiotics can cure an infection of the reproductive tract, but this doesn’t always restore fertility.
Hormone treatments and medications. Hormone replacement or medications may be prescribed to change hormone levels. It can take between three and six months before you’ll notice any effects on your semen analysis.
Assisted reproductive technology (ART). ART treatments involve obtaining sperm through normal ejaculation, surgical extraction or from donor individuals, depending on your specific case and wishes. The sperm is then inserted into the female genital tract, or used for in vitro fertilization or intracytoplasmic sperm injection.
