Which of the following statements are false regarding vasectomy?

A risk of about 1 in 2000 of pregnancy resulting from late recanalisation after previous clearance. 1 in 2000 men can become feile again due to rejoining of the two ends of the vas, so vasectomy is not 100% effective. Common complications are Scrotal bruising, haematoma, Chronic testis pain affecting quality of life (1-2%) and sperm granuloma. Sperm will still be produced by the testis but will get dissolved in the body. Sperm can still be present for a few months and so a semen analysis is done three months after vasectomy. A second contraception is needed during this period. It is done under local anaesthesia. The sex hormones will still be produced by the testes so libido and erectile function are unaffected.
