The district court in the southern city of Kraków opened the case on Tuesday, Polish state news agency PAP reported.
According to the child's parents, the new contemporary history textbook for high school students stigmatises children born through assisted reproductive technology.
The publication suggests that "test-tube babies" are not wanted, the parents said.
The passage reads: "This prompts a fundamental question: who will love the children produced in this way? The state that takes this kind of 'production' under its wing? Parental love has been and will remain the basis of every human being's identity, and its absence is the cause of almost all degeneration of human nature."
The parents are demanding a public apology on both liberal and conservative websites, as well as PLN 10,000 (EUR 2,270) from the author and PLN 30,000 (EUR 6,820) from the publisher, as compensation to be paid to an IVF charity.
The author, Wojciech Roszkowski, said his comments did not contain the expression "in vitro fertilisation" and were not meant to stigmatise children born through this method, but highlighted "concern about conceived children," the PAP news agency reported.
Meanwhile, the publisher has removed the controversial passage from the book.
The Association of Polish Journalists (SDP) said it was monitoring the case from a "freedom of speech" perspective, the PAP news agency reported.
Education and Science Minister Przemysław Czarnek, whose ministry had approved the textbook for use in secondary schools, called the lawsuit "absurd."
