Not really but I'll try.
First I'll start by saying that we are ALL connected to our mothers (whether we like it or not).
From the beginning, we were nurture to life by our mothers by way of the umbilical cord. It pumped oxygen and nutrients from mother to baby (thru one vein) and removed waste and deoxygeniated blood (thru two arteries). Without this vital process, there would be no baby, right? There would be no YOU. Therefore, I feel that it is only natural that one would look to mom when they need to feel nurtured and loved. Especially men. A mother is a little boys first love. Everything she does will influence who he becomes and how he treats others when he becomes a man.
Through her he learns about love, about trust, and about how to feel wanted and safe. When a man doesn't receive love from his mother or he doesn't trust his mother with his heart, or she makes him feel unwanted and unsafe, then it can (will) cause him to have issues later on in life.
If the relationship is healthy then he will most likely grow into a healthy individual who knows how to give and receive love while loving himself in the process. Much respect.
There are also instances where the relationship seems to be good but there are a few underlying issues. For example, some mothers create an atmosphere of dependency with their sons which can cause major issues in his personal relationships. Most likely a sneaky and manipulative momma.
I'm not covering all of my thoughts on this topic but I think you get the idea. But yes, I have noticed that men do have an attachment to their mothers, whether it be positive or negative. Some don't even realize how that relationship affects who they are today and how they handle life. Interesting topic.
