Ninety-two men were explored by depth psychological interviews before vasectomy and 12-15 months later. Eighty-six of them were completely satisfied with the operation. Six men were dissatisfied and would not undergo the operation again. Forty men requesting refertilization were also explored by depth psychological interviews one day before operation. The comparison of these two groups shows that vasectomy is problematic for men who are younger than 30 years, being in training, and whose partners are not willing to undergo sterilization as well. Men without partners and without children should reconsider their decision for vasectomy and particularly those who show the above-mentioned characteristics and/or those who make the decision without being able to use condoms and/or are unable to handle the situation in case of an abortion. The length of partnership is not important for the sequelae of vasectomy.
