If the ligation is 8 years old and still has the possibility of fertility, the main thing is to have the tubal reversal surgery. In clinical practice, the reversal surgery is now done under a surgical microscope, so the success rate of reversal is very high. If this is the idea, it is recommended to go to the hospital to complete the reversal surgery as early as possible, preferably before the age of 35, because the ovarian function of women declines as they age. If even if the unblocking surgery is done very successfully, but ovarian function declines and ovulation dysfunction occurs, pregnancy will not occur, it is recommended to have the revision surgery done while you are young. It is also recommended to get pregnant as soon as possible after the reversal surgery because the lumen of the fallopian tube is relatively thin and if further adhesions occur, it will lead to the inability to get pregnant.
