Resumo: | The aim of the present work was to study the spermatic feasibility after 20 years of freezing, thawing and refreezing. A young man affected by testicular cancer sought the sperm freezing service. After 20 years, the samples were thawed and frozen again. After two days, thawing and analysis of the material took place. Comparison of the findings showed activity reduction from the first thawing to the fresh semen 59.09%. For the second thawing it was 77.27%. Considering the morphology, first thawing showed a reduction of 44.64% in relation to fresh semen. In the second thawing, the reduction was of 75%. Spermatic motility decreased by 64.28% in relation to fresh semen and 92.85% at the level of second thawing. The patient had gone through in vitro fertilization in 2007, obtaining success in the first one attempt. |
