title: [Pregnancy by a man with severe oligospermia after vasectomy: a case report].
abstract: OBJECTIVE
  To analyze the risk of pregnancy in the woman whose husband has severe oligospermia after vasectomy.
  
  
  METHODS
  A woman was found pregnant, whose husband, a 35-year-old man, had received vasectomy two years before. Two seminal examinations at the interval of 7 days showed the total number of motile sperm to be 0.047 x 10(6) and 0.044 x 10(6), respectively. DNA analysis after miscarriage exhibited a 99.9996% relative chance paternity (RCP).
  
  
  RESULTS
  DNA analysis proved the biological paternity of the man with severe oligospermia after vasectomy.
  
  
  CONCLUSIONS
  A man with severe oligospermia after vasectomy could make his wife pregnant.
