|Vasectomy complications are minimal and these include hematoma and infections
It is the most common complication, the incidence of which is about 2%. Infection is also common (3.4%). One important factor which determines the likelihood of complication is the experience of the surgeon performing the procedure. The more experienced the surgeon, the lesser is the probability of complications.
2. Sperm granuloma:
The sperm production takes place in the testis, under a highly protective environment. Otherwise, sperms produced would be destroyed by one's own system. In some cases, following vasectomy some sperms may leak out, leading to attack by the immune system, resulting in a localized swelling (inflammation). In most of the cases, this does not give rise to any symptoms. In cases where persistent pain is experienced, a minor surgery may be required.
There has been no increased incidence of disorders related to the immune system such as rheumatoid arthritis or myasthenia gravis. Vasectomised men are also not at an increased risk of developing heart disorders or other illnesses that may require hospitalization.
Although certain studies hint about the possibility of increased risk of prostate cancer in men vasectomised some 20 years previously, the obtained data is controversial and there are no specific conclusion.
