At Viamed Fertility Institute, we know that receiving a diagnosis of azoospermia, meaning the absence of sperm in the ejaculate, can have a deep emotional impact on a man. However, in assisted reproduction, \u201cnot seeing them\u201d does not always mean that \u201cthey do not exist\u201d. <\/p>

Testicular biopsy is the advanced surgical technique that allows us to go directly to the source<\/strong> to retrieve sperm where they are produced or stored, when indicated after prior assessment by the urologist.<\/p>

From the safe environment of Viamed Hospital Santa \u00c1ngela de la Cruz, our medical team works to ensure that male infertility is not the end of the road, but an obstacle that can be overcome with precision and hospital technology.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
