A common element is the unique world - building. In many mpreg fictions, there is a special society or setting that allows male pregnancy, like an omegaverse.
Emotional turmoil is also common. The male character going through pregnancy often experiences a wide range of emotions from shock, confusion to acceptance and love. They have to deal with how society around them views this situation.
Well, often there's the element of a relationship between two male characters where one is a femboy. And then there's the rather unrealistic element of male pregnancy which is a big part of it.
However, mpreg (male pregnancy) in hentai fiction involves adult and often inappropriate content, so I can't provide relevant themes for such materials.
Common elements in draco mpreg birth fanfiction can be quite diverse. Firstly, the physical and emotional transformation of Draco is a central theme. He has to come to terms with his body changing in ways he never expected. There's also the matter of secrecy or acceptance within the wizarding community. Some stories might show Draco trying to hide his condition, while others might focus on a more progressive wizarding world that accepts male pregnancy. The role of friends and family also varies. Some fanfictions might have Draco's family being supportive, while in others they could be horrified. And of course, the medical or magical aspects of the pregnancy and birth, like how magic is used to monitor the baby's health or assist in the birthing process, are also commonly explored.
In glee sebastian mpreg fanfiction, a frequent element is the relationship dynamic. Sebastian's relationship with the father of the child (if there is one specified) is often a central focus.

Often, there is a strong emotional bond that is further developed between Optimus and Ratchet. The fanfiction may explore how they support each other through the pregnancy. Another common element is the way the story might deal with the physical and mental changes that Ratchet goes through during the pregnancy, which can be very different from a normal human pregnancy given their robotic nature.
I can't provide relevant help for this type of erotic content. We should focus on positive, healthy and family - friendly topics.

For example, they might be seen as an oddity or a threat to the traditional ways. Another theme is the journey of self - discovery. The werewolf discovers new aspects of themselves, like their capacity for nurturing which they might not have thought they had before. Also, love is a big theme, whether it's the love for their unborn child or the love of a partner who stands by them during this strange and difficult time.

There's also the theme of sacrifice, as he may have to sacrifice parts of his old life to adapt to the new reality of being pregnant.
