Policies that increase and improve family contact are also essential as well as policies to prevent and respond to sexual harassment and rape of male and female prisoners. Female prisoners are likely to find strip searches particularly traumatic, and policies regarding strip searching should be separately and carefully formulated as it regards male and female prisoners. Other matters to be considered include: arrangements for privacy when people are required to remove their clothing; privacy in toilets and showers; use of private locks on cells; provision of hygiene items for women; and minimising indignity in the way urine and other samples are collected for drug testing. Poor prison conditions, lack of proper care and facilities, and the high level of stress that accompanies incarceration may place at risk both the health of a pregnant woman and that of her unborn child. Pregnant women should only be held in prison in the most extreme circumstances, such as when there is a concrete threat of violent crime. Special provisions should be made for ante and post-natal care and treatment, and babies should not be born in prison.
