Titles have changed because men as well as women can be nurses. It was, in most countries, a wholly female occupation. The titles were designed for females and have now been revised to be genderless. The exception to this is midwife, a term still used because it seems natural that a nurse helping a mother through childbirth should be a female. There are some males acting as midwives. The supervisory body for UK nursing is the Nursing and Midwifery Council.
