Men who have problems with the reproductive system might need one of these two methods as an element of the fertilization process. These two procedures are constantly performed in medical clinics in order to extract sperm. The methods are necessary if the person has problems in sperm production or because of the obstruction for the flow of semen during ejaculation. The sampling can be conducted in two different ways: TESA ivf and TESE procedures.
During the first procedure, the physician applies a needle to aspirate semen. The process includes taking a small sample of tissue for the analysis which will be done under the microscope. The tissue is analyzed for the amount of sperm in it if it is enough the doctor takes another tissue in order to conduct sperm extraction.
The second method of taking the sampling includes a surgical biopsy of the testis. Lately, there is a discussion about these two methods, some experts suppose that tesa ivf is a better choice because it doesn't include any surgical intervention. These specialists also claim that for TESE it is required to take general anesthesia for this process. However, it is a false idea because it can be conducted harmlessly and easily using a cord block.
Some researchers analyzed the consequences of these two methods in the same testis of men. The experts took 3 examples from each testis and analyzed the consequences of these methods. The researchers discovered that TESE demonstrated higher capacity at receiving semen according to the amount and consecutive mobility of the sperm discovered during the investigation. So the experts came to the conclusion that an improved possibility of cryopreservation of sperm received by TESE comparing with the second method exists. It indicates that cryopreserved sperm can be used in the following cycles and there is no need for this person to pass through these procedures again.
