Czech health minister Svatopluk Němeček says the option of surgical castration for sexual deviants should be maintained if they choose to undergo such treatment. His comments followed a report on the process in response to criticism from the European Union. The report to the government on Monday pointed out that 88 percent of those questioned said they had volunteered freely for castration and just over half said they would make the same choice again. The report said castration, which stops the influence of the male hormone testosterone, results in repeat sexual offences by only 4 percent of former offenders. Less than 10 such operations are carried out on average in the Czech Republic every year.
