Peroralna kontracepcija: razlika med redakcijama

odstranjenih 96 zlogov ,  pred 15 leti
Obstaja več različni tipov 'tabletk'. Na splošno so jih vse razvili na podlagi različnih sintetičnih estrogenov in progestinov - kemičnih analogov naravnih hormonov [[estrogen|estrogena]] in [[progesteron|progesterona]]. Najbolj pogoste oblike vsebujejo 20 do 40 mikrogramov ethinil estradiola (estrogenska komponenta) in fiksno ali variabilno dozo (bi ali tri fazne tabletke) levonorgestrela ali norethindrona (progestagenska komponenta).
 
==EffectivenessUčinkovitost==
Največkrat za učinkovitost različnih metod kontracepcije uporabljamo ''[[Pearlov indeks]]''. Izraža število zanositev normalno plodnih žensk v obdobju enega leta. Vsaka metoda omejevanja zanositve ima dve številki Pearlovega indeksa:
The ''[[Pearl Index]]''{{ref|1}} is often used to compare the effectiveness of various methods of contraception. It is expressed as the "number of pregnancies in 100 normally fertile women over the period of one year". Each method of birth control has two Pearl index numbers:
 
*''učinovitost metode'': na pokaže Pearlov indeks v ''idealnih'' pogojih. Po tej metodi so Pearlov indeks za učinkovitost kontracepcijskih tablet ocenili na 0,3 - 1,25, kar pomeni, da bo ob idealnih pogojih v enem letu zanosilo 0,3- 1,25 žensk od 100-tih, če bodo popolnoma urejeno uporabljale tabletke (Pearlov indeks = 0.3 to 1.25).
*''method effectiveness'': is the Pearl index number for use under ''perfect'' conditons. The method effectiveness Pearl index for the Pill has been measured as low as 0.3 and as high as 1.25, which means that under ideal conditions, anywhere from 0.3 to 1.25 out of 100 users will become [[pregnant]] during one year of perfect use (Pearl index = 0.3 to 1.25).
 
*''uporabniška učinkovitost'': nam pokaže Pearlov indeks v ''tipičnih''(realnih) pogojih. Po tej metodi so Pearlov indeks za učinkovitost kontracepcijskih tablet ocenili na 2,15 - 8,0, kar pomeni, da bo ob povprečnih pogojih v enem letu zanosilo 2,15- 8,0 žensk od 100-tih, če bodo povprečno urejeno uporabljale tabletke (Pearlov indeks = 2.15 to 8,0).
*''user effectiveness'': is the Pearl index number for use under ''typical'' conditions. The user effectiveness measured by the Pearl index for the Pill has been measured as low as 2.15 and as high as 8.0, which means that anywhere from 2.15 to 8.0 out of 100 women will become [[pregnant]] during the first year of typical use (Pearl index = 2.15 to 8.0). {{ref|2}} {{ref|3}}
 
Dosti žensk občasno pozablja jemati tabletke, kar zmanjšuje njihovo učinkovitost. Idealni pogoji pomenijo recimo jemanje tabletke vsak dan ob enaki uri 21 dni, nato sledi pavza 7 dni (odvisno tudi od tabletk).
Many women occasionally forget to take the Pill daily, impairing its effectiveness. Correct use of the pill usually implies taking it every day at the same hour for 21 days, followed by a pause of seven days.
 
Tudi sočasna uporaba drugih zdravil lahko zmajša delovanje tabletk, zaradi interakcij v metabolizmu hormonskih komponent. Tudi driska bo lahko zmanjšala učinkovitost tabletk, ker se hormoni ne pravilno absorbirajo iz črevesja.
Use of other medications can prevent the Pill from working, due to interactions with the metabolism of the hormonal constituents. [[Diarrhea]] will also stop the Pill from working, because the hormones are not properly absorbed by the bowels.
 
Medtem ko so tabletke navadno učinkovite, pa niso uspele preprečiti "nezaželenih nosečnosti". Po statistikah [http://www.agi-usa.org/ The Alan Guttmacher Institute (AGI)] se je po uvedbi kontracepcijskih tabletk število splavov povečalo na 1,000,000 na leto, čeprav se trenutno zmanjšuje. To pripisujejo tudi večji pogostosti pričakovanj, da spolna aktivnost ne bi nikoli povzročile rojstva, tudi če kontracepcija ne uspe.
While the Pill is usually effective, its wide availability has not prevented what some call "unwanted pregnancies". In the USA, the rise in widespread use of the Pill has coincided with a rise in the abortion rate to a level that is consistently above 1,000,000 per year, according to AGI statistics. This can be attributed to an increased expectation that sexual intercourse never needs to result in the birth of a baby, even if contraception fails.
