Azoospermia is a medical condition characterized by the absence of sperm in a man's semen. This condition can lead to infertility, making it difficult for couples to conceive naturally. Azoospermia can be classified into two main types: obstructive and non-obstructive. Obstructive azoospermia occurs when there is a blockage in the reproductive tract, while non-obstructive azoospermia is due to issues with sperm production in the testes. Diagnosis of azoospermia typically involves a semen analysis, hormone testing, and sometimes genetic testing. Treatment options vary depending on the underlying cause and may include surgical procedures, hormone therapy, or assisted reproductive technologies like in vitro fertilization (IVF). Early diagnosis and intervention can improve the chances of successful conception.
