Deferentectomy is a medical term that refers to the surgical removal of the vas deferens, which carries sperm from the testes to the urethra. The word is spelled dəˌfɛrənˈtɛktəmi in IPA phonetic transcription. The first syllable, də, is pronounced like the "duh" sound in "duck," while the second syllable, ˌfɛrən, is pronounced like "ferrin" with a slight emphasis on the second syllable. The last syllable, ˈtɛktəmi, is pronounced like "tek-tuh-mee." This complex pronunciation makes the word sound intimidating, but it is important for medical professionals to know and use.
Deferentectomy is a medical term that refers to the surgical removal or excision of the deferent duct. The deferent duct, also known as the vas deferens or ductus deferens, is a long, muscular tube that transports spermatozoa from the epididymis into the ejaculatory ducts. This surgical procedure is primarily performed to achieve sterilization in males, as it disrupts the pathway for sperm to be included in the ejaculatory fluid.
During a deferentectomy, a small incision is made in the scrotum, typically near the base of the penis. Through this incision, the surgeon locates the deferent duct, which is carefully isolated and cut. Once the duct is severed, the two ends are either tied off or cauterized to prevent future reconnection or leakage. In some cases, the severed ends may be sealed with surgical clips or sutures. This effectively blocks the passage of sperm and prevents fertilization.
Deferentectomy is a relatively simple and safe surgical procedure that is often done under local anesthesia on an outpatient basis. It is considered to be a highly effective method of permanent contraception, commonly referred to as a vasectomy. After the procedure, it takes some time and a few subsequent tests to confirm the absence of sperm in the semen, after which the individual can rely on this method for birth control. However, it is important to note that deferentectomy does not shield against sexually transmitted infections (STIs), and protected sexual practices are still advised.
