There are an excessively large amount of articles relating to both topics and displaying them on a single template is and will be increasingly large and unweildy
Because of the large amount of articles, it is hard to display these in specific groups without making the template more confusing.
There is significant cross-over in these topics, there are also many structures and articles unique to each topic. A split would retain common structures in each template but also allow unique topics to be added, including a suite about sex determination, sexual differentiation, and sexual dimorphism, which are very relevant topics.
There is no reason that we need to be beholden to the terminology in Gray's Anatomy
