What are Assisted Reproductive Technologies (ART)?
The new forms of fertility treatment – collectively known as Assisted Reproductive Technologies (ART) – incorporate many methods of sperm retrieval and preparation. Once the sperm have been processed to ensure optimal fertilizing potential, they are used in a variety of procedures that aid the process of conception. These procedures include artificial insemination (AI), in vitro fertilization (IVF), and sperm microinjection techniques. [Back to Top] How is sperm retrieved for ART treatments? Sperm retrieval is not limited to ejaculated semen. With today’s technology, sperm can be obtained from men with azoospermia (lack of sperm) that is caused by an obstructive lesion, failed vasectomy reversal, inherited absence of the vas deferens, or other uncorrectable blockage. By applying microsurgical methods in a process known as micro epididymal sperm aspiration (MESA), sperm can be gathered close to the blocked portion of the epididymis, the elongated, coiled duct that provides for the matur
