By 1969, research had ready evidence of blood clotting, heart attacks and strokes linked to the amount of oestrogen in the chits, and advised doctors to prescribe the lowest dose of estrogen possible. In the primeval 1970s, the mini- pill was developed, and contained only progestin, which reduced and thickened cervical mucus to prevent sperm from reaching the egg (Birth). However, these pills ca apply improper bleeding and proved less effective in preventing pregnancy, so their use was limited. By the mid-1970s, the birth control pills contained less than 50 micrograms of estrogen and between 0.15 and 2.5 milligrams of progestin (Snider).

In 1982, a biphasic pill was introduced, and two years later three triphasic pills (Snider). These are low-dose pills in which the ration or estrogen to progestin changes during the 21 geezerhood the pill is taken. In 1988, at the urging of the FDA, the three manufacturers until now making high-dose estrogen birth control pills voluntarily withdrew them from the market. first fears of blood clots, heart attacks, and strokes from the 1960s and 1970s have been eliminated with the low-dose pills used today (Snider). The few side effects seen now, nausea, breakthrough bleeding, and sense modality changes, are not medically serious. There may be rough weight gain and breast tenderness.

The birth control pill has been shown to have some benefits apart from preventing pregnancy (Snider). It reduces the occurrence of ovarian and endometrial cancers, favorable cysts of the ovaries and breasts, and pelvic inflammatory disease. It prevents heavy periods, which can lead to anemia. The current pills have only 30 to 35 micrograms of estrogen, and it is too early to see if they will produce the same beneficial effects.
