Ectopic pregnancy is a pregnancy in which the fertilized egg is laid outside of the uterine cavity, which is commonly referred to as tubal pregnancy. For women of childbearing age, when the doctor recommends removing the affected tube in case of ectopic pregnancy, they cannot help but ask, “Can I still have a baby after removing one of my tubes? The answer is yes, the chance of pregnancy and the length of time to prepare for pregnancy are mainly related to the opposite fallopian tube. A normal woman has two fallopian tubes in her pelvis, the inner one connected to the uterine cavity through the interstitial part and the outer one connected to both ovaries through the umbilical end. The ovum is obtained from the umbilical end of the fallopian tube and is fertilized by sexual intercourse with male sperm in the fallopian tube, which means pregnancy. When a patient with ectopic pregnancy has one fallopian tube removed, as long as the function and morphology of the opposite fallopian tube are normal and there are no abnormalities in the ovaries and uterine cavity, the patient can theoretically conceive and have a healthy baby, but the chance of pregnancy is relatively lower than that of women with bilateral fallopian tubes, and the preparation time for pregnancy is relatively longer. If there are functional or morphological abnormalities in the opposite tube, such as hydrocele, pelvic inflammatory disease or Mycobacterium tuberculosis infection, which causes narrowing of the inner tube adhesions or torsion of the outer tube adhesions, the egg cannot meet the sperm or the fertilized egg cannot move normally to the uterine cavity for implantation after meeting. In this case, patients with ectopic pregnancy who have had one tube removed are largely infertile or have a significantly higher chance of having another ectopic pregnancy if the condition of the opposite tube is not improved. At present, the chance of fertility can be greatly increased by improving the condition of the fallopian tubes through relevant medical techniques, such as laparoscopic tubal adhesion separation, shaping and recanalization, i.e. minimally invasive surgery, which has small incisions, fast recovery, good treatment effect and relatively economical cost. For some patients who have one fallopian tube removed for ectopic pregnancy and the opposite fallopian tube is normal, but the ovary does not ovulate or ovulates little, such as polycystic ovary syndrome; or the uterine cavity is abnormal, such as the endometrium is too thin causing the fertilized egg not to be easy to settle, or early miscarriage, the treatment effect can be achieved by regulating the hormone level in the body through medication. If the appeal is unsuccessful, we can make use of assisted reproduction techniques such as IVF-ET (in vitro fertilization), which is relatively mature in clinical practice, has a wider audience, and the cost is much lower than in the past. In summary, after removal of one fallopian tube in ectopic pregnancy, if the opposite fallopian tube is normal and there are no abnormalities in the ovaries and uterus, the patient can have another baby. However, the chance of conception is reduced and the preparation time for pregnancy is prolonged compared to those with bilateral fallopian tubes.
