Man sues neighbor he paid to get his wife pregnant but failed after 72 attempts

In Stuttgart, Germany, is taking place the judgement of a man who was hired to get his neighbour’s wife pregnant.
Apparently, Demetrius Soupolos,, 29, and his wife Traute (former beauty queen), wanted a child for a long time, but Demetrius was told by a doctor that he was sterile.

To overcome this problem, Soupolos, decided to hire his neighbour, Frank Maus, 34, to impregnate his wife. Since Maus was already married and the father of two children, the plan seemed promising.
Soupolos paid Maus $2.500 for the job and for three
evenings a week for the next six months Maus tried desperately, a total of 72 different times, to get the job done and make Traute pregnant.
When his own wife started to complain he explained, “I don’t like this any more than you, I’m simply doing it for the money. Try and understand.”
When Traute failed to get pregnant after six months, however, Soupolos was not understanding and insisted that Maus have a medical examination, which he did.
The doctor who did the examination concluded that Maus was also sterile, shocking everyone except his wife who was forced to confess that Maus was not the real father of their two children.
Now Soupolos is suing Maus for breach of contract in an effort to get his money back, but Maus refuses to give it up because he said he did not guarantee conception, but only that he would give it an honest effort (or 72).
