Urgent contraceptive will may cause ectopic pregnancy Should choose regularly to practise contraception
Relate to the fact that ectopic pregnancy is on urgent contraceptive, the problem of how to use contraceptive correctly, I have interviewed relevant experts.
The expert understands ectopic pregnancy
Ectopic pregnancy, is called " ectopic pregnancy " too on medical science ,Say popularly, do not the embryonated egg burn smoothly the bed is in the uterus, but in other places, the bed is on the oviduct that the most common one burns. This is that one kind threatens woman's healthy disease seriously, if diagnose that will not cause massive haemorrhage in time, jeopardize the life, or lose fecundity.
Mention whether ectopic pregnancy and urgent contraceptive have been contacted, Chinese Medical Association gynecological scientific LiNan Cheng, chief of research institute, General Board of association and birth control of Shanghai introduce one research that Shanghai cooperate with U.S.A., show to 136 comprehensive appraisal results done about research institute of urgent contraceptive and ectopic pregnancy relation of the past: In 15696 women who take urgent contraceptive of promise progesterone of left alkyne, have 307 pregnant examples, among them the ectopic pregnancy person is 3, accounts for 1% of the pregnant number of people, the incidence of the normal pregnant women's ectopic pregnancy is 0.8% - 2%, prove urgent contraceptive does not increase the emergence of ectopic pregnancy.
Cheng LiNan says: "There are many to exchange sense factor ectopic pregnancy, such as numerous stream of people, sexual life being too frequent and active, etc. Ectopic pregnancy is only a superficial phenomenon, we should see through the appearance to perceive the essence: Under the the same condition, we want, compare with, down, the intersection of philtrum and the intersection of patient and rate and patient of philtrum ectopic pregnancy rate that take medicine of ectopic pregnancy that take medicine. " She says, urgent contraceptive is through proving clinically for a long time, will not increase the rate of ectopic pregnancy.
But analyze urgent contraceptive cause mechanism of ectopic pregnancy in " the the intersection of Chinese and obstetrics and gynecology " of People's Health Publisher that 1999 publish: "Progestogen of the low dosage has not inhibited ovulating, but obstacle of wriggling and happening of the oviduct, so oviducal gestation (namely ectopic pregnancy) Obviously increase. "
Gynaecologist of Haidian hospital Ni Jun thinks there is certain relation in such urgent contraceptive and ectopic pregnancy.
She says: "One slice of dosage of such urgent contraceptive is very large, contain a large amount of progestogen, it is equivalent to 6 times of the content of progestogen of regular contraceptive, after taking, the content of human progestogen rises rapidly, reduce again, membrane bleed, will prevent embryonated egg from wear bed in the uterus in this way. "
It decides it can not reach the result practising contraception that she says such contraception mechanism, for example have situation that embryonated eggs have already form been before takinged. "The embryonated egg sends the uterus after the oviduct becomes pregnant, depend on the swing of oviducal cilium and wriggling of smooth muscle. After the medicine influences the oviducal wriggling, the road to the embryonated egg is obstructed, can't enter the uterus normally, cause ectopic pregnancy. "
Ni Jun thinks there are relations in administration and ectopic pregnancy of urgent contraceptive, " if form the embryonated egg before taking, embryonated egg inhibit, reach palace, cause ectopic pregnancy probably. Some patients of my are very young, do not have gynecological disease like pelvic inflammatory disease, but find ectopic pregnancy, these, perhaps with having relations to abuse urgent contraceptive.
