In medical terminology, obstructive refers to a blockage or obstruction. In the context of reproductive health, obstructive azoospermia is a condition where sperm production occurs, but due to a blockage in the sperm ducts, no sperm is present in the semen.
This blockage may be congenital or caused by factors such as infection, trauma, or surgical procedures.
Sperm can be retrieved through surgical techniques like PESA, MESA, and TESA and used in IVF treatment.
