Over the next decade and a half, other types of progestogen-only contraceptive were developed: a low-dose progestogen only pill (1973); Progestasert, the first hormonal intrauterine device (1976); and Norplant, the first contraceptive implant (1983).
Selama dekade setengah berikutnya, jenis kontrasepsi hanya-progestogen dikembangkan: pil hanya-progestogen dosis rendah (1973); Progestasert, alat kontrasepsi hormonal pertama (1976); dan Norplant, implan kontraseptif pertama (1983).
