Overview
Trinordiol is a contraceptive pill which combines two hormones - progestogen and oestrogen - in synthetic versions. It is a triphasic pill which means that each 21 day pack contains three types of tablets, each with a slightly different dose of hormones in it.
Described as a revolution, 'the Pill' changed attitudes towards contraception in society. The pill combined oestrogen and progesterone, taken by mouth to inhibit fertility. Combined oral contraceptives were first approved for use in the United States in 1960, and became the most popular type of birth control, being about 99% effective. The first contraceptive pill was available in New Zealand in 1961, by which time people were desperate for reliable birth control. New Zealand women were quick to take it, and became some of the highest users in the world.
This object was collected by Dame Margaret Sparrow, one of New Zealand’s leading specialists and advocates on birth control and sexual health.
