A Mirena IUD lasts 5 years actually. IUD = Intrauterine device, costs few hundred dollars, not entirely sure, but probably ~ 300? Most commonly nowadays IUD contain locally releasing hormones, such as Mirena. The failure rate of birth control pills is up to about 3% per year due to imperfect use. The failure rate of IUD is only about 0.2%. A family doctor can place an IUD, but some will refer to a gynecologist.
对女人来说,避孕药绝对不是小事情。 2 ^- M/ f" H8 M) D( s' r6 @* w. t0 W
所有的避孕药的机理,简单来说,就是抑制女人的卵巢排卵以起到避孕的作用。有些人生殖力强,停药后卵巢的功能就能恢复;也有些人的生殖力弱,停药后卵巢的排卵功能很难恢复,再要怀孕就很难了。特别是用药时间越长,卵巢受到的打击就越大。所以这个因人而异的避孕药,也要因应自己的需要来选择了。( C3 b9 T' H$ Q ?

我们临床上也碰到过因服用避孕药而导致的不孕症,治疗的难度就相当大,因为她体内的激素水平乱了,很难达到怀孕所要求的双相体温。如果只是单纯的月经不调,阴道炎症,或肝气郁结等导致的不孕症,就好治多了。
