...in France, getting a vasectomy for contraceptive reasons was considered illegal until 2001 because of an obscure provision in the Napoleonic Code outlawing self-mutilation. (In 2000, an international birth control advocacy group launched a “vasectomy tourist” campaign, encouraging French men to pop over the Channel to get the snip.) [...] Many countries restrict access to vasectomy: in Finland, for example, you must have had three children or be over 30; in Russia, you must have had two children or be over 35. In some places, such as Iran, vasectomy is illegal, and in dozens of countries the legal status of vasectomy is still unclear.
