What is sperm search?
Some men are infertile because they have either a low level or a complete absence of sperm in ejaculation. In such cases, they may apply for sperm search to help them conceive with a partner, as the use of medical procedures to draw sperm can increase their chances of conception during processes such as in vitro fertilization (IVF). Sperm can be taken from the testicles or epididymis and there are several different ways to get about it. Some require cut in the scrotum, while others include the use of needles to draw sperm.
Sperm obtaining is useful for men who have a low number of sperm or motility problems, allowing them to reproduce when their sperm is unable to naturally impregnate a woman. Other men decide to do this procedure after vasectomy, especially if reverse vasectomy is ineffective because they can allow them to have children, even though they have undergone surgery to prevent reproduction. In other cases, it may be necessary to load the spermifotoz vas deferens errorsor is the seed tract blocked. In general, if a man produces some sperm, he can use this procedure to help him reproduce, even if this is not always successful.
One of the main methods of obtaining sperm is microsurgical epididymal aspirations of sperm (Mesa). In this process, the epididymis is cut, so the sperm can be downloaded. Epididymis is usually a preferred place for sperm harvesting, because the sperm collected from this area of the body tends to respond to the best for cryoconzervation in which the sperm is frozen for future use.
Less invasive - and often less successful - is the procedure of percutaneous aspiration of sperm (pesa) that uses the needle to aspirate sperm without required to cut in the scrotum. The sperm can also be taken from the testicles when there is not much in the epididymis, but the sperm in this area may be harder to freeze. The process of using sperm from the testes is called the testes of sperm extraction(TESE). It includes cutting small tissue from the area and collecting any sperm on the sample.
After obtaining sperm, which tends to be an outpatient procedure, several medical procedures may follow the results of conception. For example, during IVF, eggs and sperm are removed from the pair and then connected to the tube, making the concept more likely. However, the procedure with the highest success tends to be an intracytoplasmic sperm injection (ICSI) in which a single sperm is injected into the egg. This is technically considered to be the type IVF and is usually the most likely method that results in conception after the sperm.
