This research focuses on the possibility of discrimination towards men and any violation of men's right to parenthood. In modern times, the obsolete prejudices about men and their detachment from the upbringing of children started fading; thus is urged to examine the actual situation of men in the matter. That is to say, this paper addresses the issue from its ontological definition to the stipulated by legal bodies. It reviews the data about fathers’ (singles or in a same-sex relationship) personal experiences and society's reception of this new form of family. It compares the situation between men and women, analyzes the information, and intends to discover if there is any pattern that reflects a bias against men and the desire to become a father.
