minipillAn oral contraceptive (OC) which contains a very low-dose (0.35 mg) progestin, a low-dose synthetic progesterone norethindrone, and an extremely low dose of oestrogen. The minipill reduces sperm penetration of cervical mucus, interferes with luteinisation and implantation, and decreases gonadotropin secretion. It may be less effective than combined OCs and is associated with dysmenorrhoea.
