Document Summary

National study done in 2009 found that women rely most on male condoms, secondly on oral contraceptives, and the third most popular method was withdrawal. A study found that teenagers use the male condom most, the pill second, and withdrawal third. As teenagers get older and form longer-term relationships, they switch from condoms to the pill. Combination pill a birth control pill that contains synthetic estrogen and progesterone. Minipill a birth-control pill that contains synthetic progesterone but no estrogen. The combination pill fools the brain into thinking the woman is already pregnant, so no additional ova mature or are released. The progestin inhibits the pituitary"s secretion of luteinizing hormone (lh), which would otherwise lead to ovulation, the woman continues to have her period but there are no unfertilized ova sloughed off. Progestin in the combination pill also increases the thickness and acidity of the cervical mucus.
