There is no necessary connection between sleeping position and the condition of the fallopian tubes. If the fallopian tube is open on one side, you can have intercourse during ovulation on the open side of the tube for better results, but it has nothing to do with the sleeping position. If one side of the fallopian tube is open, you can monitor the ovulation date of the ovary on the side that is open, and the chances of getting pregnant will increase if you have intercourse during ovulation. Sleeping position after intercourse has no effect on the chances of pregnancy. If one side of the fallopian tube is blocked, it is not recommended to have intercourse during the ovulation period of the ovary on the blocked side, as the sperm and egg tend to unite at the blocked tube and ectopic pregnancy occurs. If only one side of the fallopian tube is open, it is recommended to go to the hospital for examination and treatment, and fertilization under the guidance of the doctor. During the preparation for pregnancy, you should keep a happy mood, let nature take its course, and do not have too much pressure.
