Microsurgical Sperm Aspiration Basics
The term microsurgical sperm aspiration is used to describe a variety of techniques used to retrieve a patient’s sperm from the testes, vas deferens, or epididymis. In the case of obstructive azoospermia, mature sperm is usually extracted from the epididymis, which is a narrow tube that connects the vas deferens to the testes. In the case of non-obstructive azoospermia, sperm are typically retrieved directly from the testicles.
Once extracted, the sperm can be used for in vitro fertilization (IVF) or cryopreserved. If using the sperm for IVF, we ideally will coordinate the sperm retrieval procedure to line up with the egg retrieval step. We also utilize a process known as intracytoplasmic sperm injection (ICSI), which is an advanced fertility treatment option that involves injecting a single sperm straight into an egg using a very fine needle.
