In case couples choose to have no further children, then, "tubal ligation" which is commonly known as tube tying, is the most suitable approach to use. This process is successful and risk-free. However, when tubal ligation cannot occur maybe probably or fails, then, your partner can opt for vasectomy. Vasectomy is a brief surgical procedure that blocks the sperm from reaching into the semen hence no chances of causing pregnancy to a woman. After either of these two techniques has been done, none of them can be turned back to its normal state, so make up your mind about them wisely.
