Theoretically speaking, the pregnancy rate is not high when there is only one fallopian tube, and the chances of success are not as high as when both fallopian tubes are open. Women usually alternate between the left and right fallopian tubes during ovulation, which means that each ovulation takes place through only one fallopian tube, not the total ovulation on one side, so even if you can get pregnant, the chances of getting pregnant are reduced by half compared to when both fallopian tubes are open. For those who have only one fallopian tube, it should be determined that the tube is open, and gynecological examination should be performed to clarify the function of the entire reproductive system and to exclude other factors causing infertility, such as untreated vaginitis, cervicitis, endometritis, pelvic inflammatory disease, etc. Such diseases can damage the mucous membrane of the fallopian tubes, causing them to become narrow or blocked, thus causing infertility. In addition, it is necessary to clarify the ovulation of the ovaries and go to the hospital for ultrasound monitoring of ovulation 2-3 days after menstruation to find out the exact period of ovulation and have intercourse during this period to help improve the chances of conception. For ovarian failure to ovulate, the cause needs to be identified, treated actively and, if necessary, treated with ovulation promotion therapy. Generally, for people with unilateral open fallopian tubes, their preparation time is longer compared to normal people, so they should be prepared psychologically and avoid giving themselves too much psychological pressure.
