The concept of progestogen only oral contraception led on to the development of long-acting contraceptives involving progestogen alone. They have in common a thickening effect on the cervical mucus and the ability to render the endometrium less capable of allowing implantation of an embryo. Disturbance of the menstrual cycle and, in particular, irregular bleeding can be a problem. Long-acting hormonal contraception can be administered by injection, implants, vaginal rings and as part of a special intrauterine contraceptive device (Mirena -Schering).
