The increasing use of emergency contraceptive pills (ECPs) does not seem to reduce the number of induced abortions as would be expected, indicating that women use ECPs might also be a strong factor affecting their final efficacy. The study aimed to understand the attitude towards, and use of, ECPs among women seeking an abortion.


A cohort study was conducted via face-to-face questionnaire interview among women seeking abortion in Shanghai, China. Logistic regression analysis and 2 test were performed for statistical analysis.


The response rate was 99.3%. Among all 5677 respondents aged 15–48 years, 48.8% were ECP ever-users. Compared with ever-users, ECP never-users were less likely to have used contraception during the present cycle of conception (P < 0.001). In response to the question on the main reason for non-use of contraception, ECP never-users were less likely to realize the risk of pregnancy and had less contraceptive knowledge (P < 0.001). Among 2773 ECP ever-users, 72.7% did not use ECPs to prevent the current pregnancy, mainly due to lack of awareness of pregnancy risk. Out of 757 women, 437 (57.7%) repeated unprotected sex after taking ECPs during the current pregnant cycle. A pharmacy was the preferred source to access ECPs, for the reason of convenience.


Non-use of ECPs was correlated to less knowledge on fertility and a lower rate of contraceptive use among abortion-seeking women. Women of reproductive age should have access to ECPs and receive sufficient information on their use. Health care providers and pharmacists should also be trained in contraceptive counselling, including ECPs.

The action of interleukin-6 (IL-6) impacts female reproduction. Although IL-6 was recently shown to inhibit cilia activity in human fallopian tubes in vitro, the molecular mechanisms underlying IL-6 signaling to tubal function remain elusive. Here, we investigate the cellular localization, regulation, and possible function of two IL-6 receptors (IL-6R and gp130) in mouse and human fallopian tubes in vivo. We show that IL-6R is restricted to the cilia of epithelial cells in both mouse and human fallopian tubes. Exogenous 17β-estradiol (E2), but not progesterone (P4), causes a time-dependent decrease in IL-6R expression, which is blocked by the estrogen receptor (ER) antagonist ICI-182,780. Exposure of different ER-selective agonists propyl-(1H)-pyrazole-1,3,5-triyl-trisphenol or 2,3-bis-(4-hydroxyphenyl)-propionitrile demonstrated an ER subtype-specific regulation of IL-6R in mouse fallopian tubes. In contrast to IL-6R, gp130 was detected in tubal epithelial cells in mice but not in humans. In humans, gp130 was found in the muscle cells and was decreased in the periovulatory and luteal phases during the reproductive cycles, indicating a species-specific expression and regulation of gp130 in the fallopian tube. Expression of tubal IL-6R and gp130 in IL-6 knockout mice was found to be normal; however, E2 treatment increased IL-6R, but not gp130, in IL-6 knockout mice when compared with wild-type mice. Furthermore, expression levels of IL-6R, but not gp130, decreased in parallel with estrogenic accelerated oocyte-cumulus complex (OCC) transport in mouse fallopian tubes. Our findings open the posibility that cilia-specific IL-6R may play a role in the regulation of OCC transport and suggest an estrogen-regulatory pathway of IL-6R in the fallopian tube.
