There is a possibility of recanalization after ligation, but whether recanalization is possible depends on the specific ligation method and the time of ligation. If the ligation has been performed for a long time, for example, 5-6 years or even more than 10 years, the possibility of recanalization is smaller, and it takes longer time and more effort to perform recanalization. If a man has had a vasectomy, the likelihood of recanalization is also less. In addition, women are slightly more likely to be recanalized after a ligation than men. If the vasectomy is successful, it is necessary to take rest and keep the vulva clean and fresh after the vasectomy. If necessary, IVF can be done. After the reversal surgery, special attention should be paid to sexual hygiene to avoid infection, which may cause the reversal to fail.
