This was in the wiki page on reproductive rights in the men's rights section.

In 2006, the National Center for Men brought a case in the US, Dubay v. Wells (dubbed by some "Roe v. Wade for men"), that argued that in the event of an unplanned pregnancy, when an unmarried woman informs a man that she is pregnant by him, he should have an opportunity to give up all paternity rights and responsibilities. Supporters argue that this would allow the woman time to make an informed decision and give men the same reproductive rights as women.[26][27] In its dismissal of the case, the U.S. Court of Appeals (Sixth Circuit) stated that "the Fourteenth Amendment does not deny to [the] State the power to treat different classes of persons in different ways."[28]

More specifically:

"the Fourteenth Amendment does not deny to [the] State the power to treat different classes of persons in different ways."

Does that mean the 14th amendment allows for discrimination by gender (or any other factor)? and on top of that the U.S. Court of Appeals decided that's a valid reason for men to continue getting screwed?
