1. In oduc ion
I is es ima ed ha a ound 30% o p egnancies a e
unplanned. Long-ac ing e e sible con acep i es (LARC)
a e me hods ha allow e ec i e con acep ion o a long
pe iod o ime, wi hou he need o use collabo a ion.
Acco ding o he ACOG guidelines, hey consis o me h-
ods adminis e ed wi h a pe iodici y o mo e han 12 weeks
[1]. LARCs, namely in au e ine de ices, may play a
b oade ole in con acep ion, and hei inc eased use may
help educe unwan ed p egnancies [2,3]. In au e ine de-
ices (IUD) include he coppe -con aining IUD and he
le ono ges el- eleasing in au e ine de ice (LNG-IUD).
The e a e h ee ypes o LNG-IUD: one wi h 52 mg le -
ono ges el (Mi ena®/Le ose ®), which eleases 20 mi-
c og ams/day o LNG; one wi h 19.5 mg le ono ges el
(Kyleena®), which eleases 17.5 mic og ams/day; and he
IUD wi h 13.5 mg le ono ges el (Jaydess®), eleasing 14
mic og ams/day o le ono ges el [4–7]. The coppe de ice
ac s mainly as a o eign body, while he LNG-IUD wo ks
by eleasing ho mone locally. The coppe de ice’s mech-
anism o ac ion consis s o : cy o oxic in lamma o y eac-
ion in he endome ium, by biochemical and mo pholog-
ical al e a ions induced by coppe , spe m and oocy e ox-
ici y and al e a ions in ubal mo ili y [8]. The LNG-IUD
wo ks h ough he ollowing mechanisms: ce ical mucus
hickening, inhibi ion o e iliza ion by inc eased p oduc-
ion o glycodelin A, glandula a ophy and pa ial inhibi-
ion o ollicula de elopmen and o ula ion [8,9].
They a e one o he mos e ec i e o ms o long-
las ing e e sible con acep ion, wi h ailu e a es o less
han 1%, o bo h pe ec and ypical use [10]. IUDs ha e
high accep abili y and con inua ion a es, which a e a ound
70% [11]. ACOG conside s he IUD o be a i s -line con-
acep ion, e en in adolescence and in nullipa ous women
[1,12].
Da a on women’s pe cep ion o he IUD and i s place-
men a e limi ed.
This s udy’s main goal is o de e mine he pe cep ion
o women abou in au e ine de ices, be o e and a e hei
placemen . I s second goal is o e i y he impac o con-
acep i e counseling in his pe cep ion abou in au e ine
de ices.

4. Discussion
The IUD is one o he p e e ed LARCs, being used by
a ound 14% o women o ep oduc i e age in Eu ope [14].
In Po ugal, i has a simila a e o use, being used by 12%

The IUD was chosen mainly by women be ween 30
and 34 yea s old. These da a do no co espond o he age
p esen ed in he las s udy on con acep i e p ac ices in Po -
uguese women, which s a es ha he IUD is mainly chosen
in he age g oup be ween 40 and 49 yea s old [15]. This may

Mos o he women included in he s udy we e ed-

These da a a e compa ible wi h o he s udies ca ied ou

The IUD con inues o be used mo e o en in mul i-

be s o he Ame ican College o Obs e icians and Gyne-
cologis s conside he IUD o be an adequa e con acep-

ioned by doc o s ega ding i s use in nullipa ous women
a e: ea o pel ic in lamma o y disease, di icul y in inse -

guidelines s a e ha he IUD is an app op ia e me hod and
can be used as a i s line in his g oup o women [1].
Despi e all he in o ma ion a ailable, 5% did no use
con acep ion p io o consul a ion. Al hough su p ising,
his ac is in line wi h he a ailable li e a u e. 3.8%

In his s udy, he p ima y eason o choosing he IUD

The as majo i y o use s conside ed ha he e was no

The p ocess was simple o co esponded o wha was
expec ed in 91% o cases. This is an impo an ou come
o be men ioned, as we did no ind hese indings in o he
s udies.
The main conce n o women ega ding his me hod
was he placemen p ocess, especially wi h ega d o he
pain associa ed wi h he p ocedu e. Pain was signi ican ly
less han expec ed by use s. The pe cep ion o co ec con-

inc eased pain in ensi y wi h gynecological p ocedu es is
he p edic ion a high le el o pain p io o he p ocedu e
[28,29]. The e is s ill no explana ion o his inding in he
li e a u e.
Ou IUD placemen p o ocol does no include he ad-
minis a ion o analgesics. Howe e , he la es Coch ane

be a use ul app oach in imp o ing he esul s.
The s eng h o his s udy is ha i is p ospec i e. This
educes possible bias as he da a was collec ed in eal ime.
The esul s can be conside ed eliable and ep esen a i e o

5. Conclusions
This s udy adds in o ma ion ega ding he pe cep ion
