In brief: Estrogen dosage
The original pill contained 150ug of estrogen.
Over the last 50'years, the dosages have dropped to 35 and 30 ug - relatively higher dosages - to 20 ug - low dosage - to a newer 10 ug pill - the lowest available. Benefits can include shorter, lighter periods and possibly improved safety and effectiveness - with increasing the days taken from 21 to 26.
