“…Men with fewer than three ejaculations per week have been reported to reach azoospermia around 5 weeks later than those with a higher number of ejaculations 25. It has also been reported that azoospermia may not be achieved until 60 ejaculates for some individuals 25. However, systematic review data indicates that by 20 ejaculates, 80% of men should show azoospermia or sperm numbers beneath detectable levels 11.…”

“…In one prospective study, the median time to azoospermia was 10 weeks, with most men (93%) being azoospermic by 20 weeks 25. Similarly, sperm have been reported to temporarily reappear in ejaculates 12 months after surgery, despite previous sperm-free ejaculates 9…”

Post-vasectomy semen analysis (PVSA) is the procedure used to establish whether sperm are present in the semen following a vasectomy. PVSA is presently carried out by a wide variety of individuals, ranging from doctors and nurses in general practitioner (GP) surgeries to specialist scientists in andrology laboratories, with highly variable results.Key recommendations are that: (1) PVSA should take place a minimum of 12 weeks after surgery and after a minimum of 20 ejaculations. (2) Laboratories should routinely examine samples within 4 h of production if assessing for the presence of sperm. If non-motile sperm are observed, further samples must be examined within 1 h of production. (3) Assessment of a single sample is acceptable to confirm vasectomy success if all recommendations and laboratory methodology are met and no sperm are observed. Clearance can then be given. (4) The level for special clearance should be <100 000/mL non-motile sperm. Special clearance cannot be provided if any motile sperm are observed and should only be given after assessment of two samples in full accordance with the methods contained within these guidelines. Surgeons are responsible both preoperatively and postoperatively for the counselling of patients and their partners regarding complications and the possibility of late recanalisation after clearance. These 2016 guidelines replace the 2002 British Andrology Society (BAS) laboratory guidelines and should be regarded as definitive for the UK in the provision of a quality PVSA service, accredited to ISO 15189:2012, as overseen by the United Kingdom Accreditation Service (UKAS).

“…26 The BAS recommends that patients should be instructed to ensure that they have had at least 24 ejaculations, 5 6 18 and preferably wait at least 16 weeks before submitting a first semen sample for examination. [27][28][29] This will reduce the number of false positive samples and thus minimise both patient inconvenience and repeat laboratory assessment.…”

informació n del artí culo La mediana de edad fue 38 añ os (28-52) y el promedio de hijos previo al procedimiento fue de 3. Antes de la vasectomía, la versió n en españ ol del IIFE-15 les fue entregada y contestada en la visita 1. Doce semanas posteriores, una segunda visita fue programada y el cuestionario fue nuevamente contestado. Se recopilaron las diferencias entre los resultados generales y los de cada dominio de manera individual. Las respuestas negativas o positivas fueron definidas como cualquier cambio en comparació n con la puntuació n previa. La prueba de Wilcoxon fue usada para el aná lisis estadístico.Resultados: La media de la puntuació n total fue 67,0775,25 vs. 67,8375,71 antes y despué s de la vasectomía respectivamente (p ¼0,07). El 38% mejoró , el 48% tuvo el mismo resultado y el 14% empeoró . No hubo cambios significativos en los diferentes dominios de manera individual excepto el del orgasmo 9,0370,83 vs 9,3670,82 en la visita 1 vs visita 2 respectivamente (p ¼0,01).Conclusiones: La vasectomía no mostró tener influencia en la mayoría de los dominios de la satisfacció n sexual de manera individual. Podríamos especular que si algú n cambio es esperado, é ste debe ser positivo, particularmente en el domino del orgasmo. Estos resultados contrastan con lo reportado en la literatura utilizando el IIFE-15.
