Zhimei sometimes feels
The encounter of life is a miracle
Because the baby can come healthy and safe
A thrilling adventure in itself
Sperm are subjected to hundreds of millions of auditions
in order to meet the egg
When they successfully combine to form a fertilized egg
The first hurdle is to smoothly pass through the bridge of life, the fallopian tube
The length of this section is 8-14 cm on one side
It depends on the peristalsis of the fallopian tubes
It takes 4-5 days for the fertilized eggs to be delivered to the uterus
However, it seems to be a calm road
Fertilized eggs can be lost! road!
If the fallopian tubes are narrowed, blocked, or underpowered, the fertilized egg remains in the fallopian tubes, where it implants and develops;
Or fall through the umbel end of the fallopian tube and implant in the ovaries or abdominal cavity, which can lead to a more rare and severe "ectopic pregnancy".
"Ectopic pregnancy" means that the fertilized egg does not go to the uterine cavity, but goes to other places.
In medicine, it has a broader definition called "ectopic pregnancy", the incidence is about 2% to 3%, the most common is tubal pregnancy, accounting for 95%, and other ovarian pregnancy, abdominal pregnancy, cervical pregnancy and so on [1].
The fallopian tubes are narrow and slender, the surrounding blood vessels are rich, and once the embryos of ectopic pregnancy grow up, they "break" the fallopian tubes, which are prone to heavy bleeding and will be fatal when severe.
Sisters who have sex, the following passage I hope you will remember:
Whether there is contraception or not, please remember that any of the following 3 symptoms appear, so go to the hospital! This is the warning signal of ectopic pregnancy!
Great aunt is late;
Bleeding that is different from normal menstruation, such as a small amount, a different color than before, a long duration, etc.;
Abdominal pain: especially lower abdominal pain, with or without nausea, vomiting, strong bowel movements, lower abdomen or bloating sensation.
At this point, don't believe the pregnancy test stick!
Go to the hospital early and win time for treatment early.
Sisters with the following 4 situations are at higher risk and should be extra careful:
1 Inflammation in or around the lumen of the fallopian tubes (most common)
Having an unclean sexual life (such as not wearing a condom) or multiple sexual partners, it is easy to be infected with gonococcus, Chlamydia trachomatis and other pathogens, and such people are more likely to have abortions, and repeated abortions are prone to upward infection of the genital tract, resulting in salpingitis. Infections can also occur after childbirth.
2 History of tubal pregnancy or surgery
If you have had a single tubal pregnancy and your fallopian tubes are still present, there is a 10 percent chance of ectopic pregnancy occurring again, and the risk of recurrence rises to more than 25 percent after more than two ectopic pregnancies [2].
Other tubal surgeries, such as sterilization, also increase the risk of ectopic pregnancy.
3 Tubal dysplasia or dysfunction
Long fallopian tubes may prevent the fertilized egg from reaching the uterus within 4 to 5 days. Endocrine disorders or psychiatric factors (anxiety, stress) can cause abnormalities in the "transport function" of the fallopian tubes [1].
4 Other
Such as IVF, smoking, endometriosis, emergency contraception failure.
Among the above factors, the first one we can control and master the most is to do a good job in contraception and sexual hygiene, and avoid tubal inflammation caused by infection.
Zhimei hopes that every baby can meet her mother as scheduled
