Vrstica 1: {{working}} '''Oralno [[kontracepcijo\|kontracepcija]]''' predstavljajo kemične substance, ki jih sprejmemo preko ust in preprečujejo normalno plodnost. Vse delujejo na [[hormon\|hormonski]] sistem. Ženske kontracepcijske tabletke so na tržišču že od zgodnjih [[1960]]-tih in so zelo popularne. Uporablja jih na miljone žensk po celem svetu: približno tretjina spolno aktivnih žensk v [[Velika Britanija\|Veliki Britaniji]], v nekaterih deželah pa dosti manj, recimo na [[Japonska\|Japonskem]]. Kontracepcijske tablete za moške so v fazi raziskav in razvoja, tako da še niso na razpolago širokim množicam. '''Oral [[contraceptives]]''' are chemicals taken by mouth to inhibit normal fertility. All act on the [[hormone\|hormonal]] system. Female oral contraceptives have been on the market since the early [[1960s]], and enjoy great popularity. It is used by millions of women around the world, though the acceptance varies by region: approximately one-third of sexually active women in the [[United Kingdom]], but much less in countries such as [[Japan]]. [[Male pill\|Male oral contraceptive]]s remain a subject of research and development, and are not widely available to the public. ==~~Principles~~Principi== Kontracepcijske tabletke za ženske so najpogostejša oblika farmakološke kontracepcije. Služijo preprečeanju [[nosečnost\|nosečnosti]]. Uporabljajo jih tudi za kontrolo [[disfunkcijske krvavitve\|disfunkcijskih krvavitev]] ali na primer za urejanje simptomov [[policistični ovariji\|policističnih ovarijev]]. Sestavljene so iz tablet, ki jih ženska jemlje dnevno in vsebujejo doze sintetičnih hormonov (vedno [[progesteron\|progesterona]] in pogosto tudi [[estrogen\|estrogena]]). Pri določenih tipih tabletk so doze hormonov prilagojene tako, da so v sihronosti z [[menstrualni ciklus\|menstrualnim ciklusom]] (dva do tri fazne tablete), medtem ko imajo druge konstantne koncentracije hormonov. Female oral contraceptives, colloquially known as ''the Pill'', are the most common form of pharmaceutical [[contraception]]. They are used to prevent [[pregnancy]]. The pill can also be used to control [[dysfunctional bleeding]] or symptoms of [[polycystic ovary syndrome]]. They consist of a pill that women take daily and that contains doses of synthetic hormones (always a [[progestin]] and most often also an [[estrogen]]). In some types of pill the doses of hormones are adjusted to be in synchrony with the [[menstrual cycle]] (two- or three-phase pills), while others keep a constant level of the hormones. ==~~Mechanism~~Mehanizem ~~of action~~delovanja== The Pill works by preventing [[ovulation]], as well as making the [[uterus]] less likely to accept implantation of an embryo if one is created, and thickens the mucus in the [[cervix]] making it more difficult for sperm to reach any egg.
