Vasectomy should not be considered a reversible method of contraception even if vasovasostomy can be offered to men to restore fertility after vasectomy. Therefore, there is a real questioning among urologists concerning cryopreservation before vasectomy. We carried out an international survey concerning the practice of cryopreservation before vasectomy and during vasovasostomy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Material and methods<\/jats:title><jats:p>An online anonymous survey was submitted from January to June 2021 to six European urological societies. The 31\u2010items questionnaire included questions about demography, habits of cryopreservation before vasectomy or during vasectomy reversal, and in case of urogenital cancers.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>228 urologists from six urological societies in five different countries (Belgium, Netherlands, Luxembourg, France, Finland) answered the questionnaire. French urologists were more in favor of cryopreservation before vasectomy than other European urologists (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.0001). They also significantly found that not talking about cryopreservation before vasectomy is a medical fault unlike other urologists (<jats:italic>p\u00a0<\/jats:italic>&lt;\u00a00.0001). The specialization in andrology did not influence the choice of cryopreservation before vasectomy (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.9452). The majority of urologists did not perform intraoperative sperm extraction during vasovasostomy (81%; <jats:italic>n<\/jats:italic>\u00a0=\u00a0127) with a significant difference between urologists with or without andrology training (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.0146). Success rates after vasovasostomy are significantly better for robot\u2010assisted surgery (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.0159) or with a microscope (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.0456) versus without a microscope.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Cryopreservation before definitive sterilization significantly varies among European urologists and seems to be mostly dictated by habits than by knowledge.
