A 41-year old male visits a urologist to learn about getting a vasectomy as a permanent method of contraception. Which statement should the nurse use during client education?

A second method of birth control is necessary until the sperm count is zero. There is no need for follow-up after that. Reversing a vasectomy is difficult, requiring microsurgery; results may be unsuccessful. There is no correlation between having a vasectomy and cardiac disease.
