一、激素避孕機(jī)制

1.抑制排卵

Preventovulationbyinhibitinggonadotropinsecretion.

抑制下丘腦的促性腺激素釋放激素因而使垂體的促卵泡素和促黃體素分泌受抑制而不發(fā)生排卵。2.對(duì)生殖器官的直接作用（1）改變宮頸粘液性狀：Theprogestincomponentthickenthecervicalmucus,retardingspermpenetration

宮頸粘液變粘稠量減少、不利于精子穿透。（2）改變子宮內(nèi)膜形態(tài)與功能：Theendometriumchangesbothinfunctionandinmorphology.It’snotsuitableforthefertilizedeggtoimbed.避孕藥中孕激素干擾了雌激素效應(yīng)，子宮內(nèi)膜增殖受抑制；腺體及間質(zhì)提早發(fā)生類分泌期變化，不適于孕卵著床。（3）改變輸卵管的功能Changethefunctionofthetube二、激素避孕遠(yuǎn)期安全性1.長(zhǎng)期服用甾體激素避孕藥與生殖器腫瘤2.長(zhǎng)期服用甾體激素避孕藥與日后生育3.長(zhǎng)期服用甾體激素避孕藥與子代發(fā)育4.長(zhǎng)期服用甾體激素避孕藥與人體三大代謝
