    Glossary Azoospermia

    complete absence of sperm in male ejaculate

    Azoospermia is a medical condition characterized by the complete absence of sperm in a man's ejaculate. This can result from either a blockage that prevents sperm from being released or a problem with sperm production in the testes. It is a significant cause of male infertility and requires thorough evaluation to determine the underlying cause and appropriate treatment options.
