- BACKGROUND: We have conducted a randomized controlled trial of totally extraperitoneal hernia repair (TEP) versus tension-free open repair (Lichtenstein repair); we have presented the results previously up to 1 year after the operation. The aim of this study was to compare patient outcome in both groups at a median follow-up of 7.3 years after operation. METHODS: Of 168 patients included in a prospective, randomized controlled trial designed to compare TEP with an open tension-free technique, 154 patients (92%) answered a questionnaire and 147 patients (88%) were followed up at an outpatient clinic after a minimum of 6 years after operation. RESULTS: Overall, 89% of patients in the TEP group and 95% of patients in the open group reported complete long-term recovery (P = .23). Permanent impaired inguinal sensibility was more common in the open group (P = .004), whereas the proportion of patients with reported testicular pain was higher in the TEP group (P = .003). Three recurrences were found in the TEP group, and 4 recurrences were found in the open group (P = .99). Four patients in the TEP group underwent operations for complications related to the hernia repair (small bowel obstruction, umbilical hernia, testicular pain, and neuralgia). CONCLUSION: Overall, both groups showed good long-term results with low rates of recurrences. However, the TEP group was associated with a higher proportion of patients with long-term testicular pain, whereas impaired inguinal sensibility was more common in the open group.

- BACKGROUND: Several animal studies have raised concern about the risk for obstructive azoospermia owing to vasal fibrosis caused by the use of alloplastic mesh prosthesis in inguinal hernia repair. The aim of this study was to determine the prevalence of male infertility after bilateral mesh repair.METHODS: In a prospective study, a questionnaire inquiring about involuntary childlessness, investigation for infertility and number of children was sent by mail to a group of 376 men aged 18-55 years, who had undergone bilateral mesh repair, identified in the Swedish Hernia Register (SHR). Questionnaires were also sent to 2 control groups, 1 consisting of 186 men from the SHR who had undergone bilateral repair without mesh, and 1 consisting of 383 men identified in the general population. The control group from the SHR was matched 2:1 for age and years elapsed since operation. The control group from the general population was matched 1:1 for age and marital status.RESULTS: The overall response rate was 525 of 945 (56%). Method of approach (anterior or posterior), type of mesh, and testicular status at the time of the repair had no significant impact on the answers to the questions. Nor did subgroup analysis of the men CONCLUSION: The results of this prospective study in men do not support the hypothesis that bilateral inguinal hernia repair with alloplastic mesh prosthesis causes male infertility at a significantly greater rate than those operated without mesh.

- BACKGROUND: Previous studies have suggested that the use of mesh in groin hernia repair may be associated with an increased risk for male infertility as a result of inflammatory obliteration of structures in the spermatic cord. In a recent study, we could not find an increased incidence of involuntary childlessness. The aim of this study was to evaluate this issue further.METHODS: Men born between 1950 and 1989, with a hernia repair registered in the Swedish Hernia Register between 1992 and 2007 were cross-linked with all men in the same age group with the diagnosis of male infertility according to the Swedish National Patient Register. The cumulative and expected incidences of infertility were analyzed. Separate multivariate logistic analyses, adjusted for age and years elapsed since the first repair, were performed for men with unilateral and bilateral repair, respectively.RESULTS: Overall, 34,267 men were identified with a history of at least 1 inguinal hernia repair. A total of 233 (0.7%) of these had been given the diagnosis of male infertility after their first operation. We did not find any differences between expected and observed cumulative incidences of infertility in men operated with hernia repair. Men with bilateral hernia repair had a slightly increased risk for infertility when mesh was used on either side. However, the cumulative incidence was less than 1%.CONCLUSION: Inguinal hernia repair with mesh is not associated with an increased incidence of, or clinically important risk for, male infertility.
