Azoospermia is a medical condition characterized by the absence of sperm in a man's semen. This condition can lead to infertility, as sperm is necessary for natural conception. Azoospermia can be classified into two main types: obstructive, where sperm production is normal but blocked from reaching the semen, and non-obstructive, where there is a problem with sperm production itself. Diagnosis typically involves a semen analysis, and treatment options may include assisted reproductive technologies or surgical procedures, depending on the underlying cause. Understanding azoospermia is crucial for men facing fertility challenges, as it can guide them toward appropriate interventions.
