Okay, so this is how Mpregnancy works In my head, It's more complicated than it Looks but Lets get Down to Business anyway.
before i get started might I add this is a theory, hint the title.
if you don't like this type of stuff might i suggest you click back. or click the little
this is no place to spread your hate, stop trying to make other people feel bad about things they like
it's wrong and makes you look like an asshole.thanks.
Knowing your Parts
Ovary: As you Might Know,a normal Woman has Two Ovaries,In this case a Male who is able to carry a Fetus only has one Ovary, so they can't reproduce as Much or as Fast as women Since males don't have Periods anyway The egg Will always be fertilized and if one disintegrates a new one will quickly take it's place
Oviduct:Transmits the egg from the ovary to the uterus
Body Cavity:When the Fetus Grows,The uterus will Expand and so will the Body Cavity
Symphysis Pubis:The Midine cartilaginous Joint,uniting the superior Rami of the left and the right Pubic bones, Since he is Male,his is above the Penis.
In Normal Adults it can be roughly Moved 2mm and with 1 Degree rotation,This Increases around the time of Childbirth.
During Delivery,Hormones such as Relaxin remodel this Ligamentous capsule allowing the pelvic bones to become more flexible.
Urinary Bladder:It serves as the temporary storage of urine, If the Baby kicks into that your in a boat load of trouble.
Vas Deferens: is a narrow, muscular tube that connects the testicles (where sperm is produced) to the urethra. During ejaculation, the sperm flows out of the testicles, through the vas deferens, and into the tube (urethra) that leads outside the body through the penis.
Several glands, such as the prostate gland, add fluid to the sperm along the way.
Penis: It has 2 functions. The male urethra runs through the penis, thus allowing males to urinate. The second function is to have sexual intercourse to allow women (or in This Case another Male) to become pregnant, or just for pleasure.
Uterus: The womb,receives, retains and nourishes a fertilized ovum,protects and nurtures the embryo and fetus prior to birth, and contracts to help deliver the baby at birth, (In my head The Seme's penis will never enter this sacred Vagina)
Rectum: Mostly for fecal matter,Mostly for Sexual Contact.
Cervix:The ending of the Vagina,and The beginning of the Uterus.
Anus: Same thing a Rectum,But is the opening.
Male Vagina: I say this because, no Birth will ever be more Difficult or more Painful (Sorry Ladies,ass baby alert) Than this one.
In order for the Fetus to get out it will have to move through the vagina, Contractions will have to Break the wall Open once more and the Babies Head will have to Move towards and Out of the anus Causing the Rectum more Pain. Uke's are stronger Than what you think.
After The Baby is born The rectum wall will sense No more pain and will send special cells to Heal the opening Towards the Vagina Opening to the Rectum and will Break when sex happens Again.(all that Healing for nothing)
When a Uke loses his Virginity, His Rectum wall is so sensitive it will break open a Little opening at the end of the wall which Leads right towards his Vagina, The seme's Penis will never hit the right angel to Go inside The vagina so don't worry for Awkward sex(Unless you want to.) This the whole New meaning of Virgin Blood.
If Lucky enough, When Climax happens Inside the Rectum, when sperm oozes out, it can make it's way through the Vagina opening, But not all the time Because when The cut is still Fresh, The Cells protecting the wall will Kill all the sperm, sometimes this wont happen so it's a "Win" "Lose" Situation.
Health and Development:Fetus and Mother
if you want The child to Have full growth Period,You will Have to Go with C-section To retrieve Fetus,It will be to Big to Make it's way Through Male torso
So I hope This explains some Things, I will be working one more so see you Later
Edit:to the one arguing with me about the fact he wouldn't be able to carry the child because the organs would get in the, must i say in regular pregnancy(involving a woman) her organs get pushed out of the way so the baby can grow properly so in a way i this theory the male body would be able to do this too
I know this deviation is old, but I'm considering writing an m-preg fanfic and I find this deviation very intriguing. My two main characters are shapeshifters and, therefore, are capable of engaging in a behaviour engaged in by flatworms, called "penis fencing." Basically, either one of them can impregnate the other. I would imagine, then, that in my fic, male shapeshifters' reproductive systems look like this.
I realize this isn't meant to be a ligit thing but if you're trying to say that this could happen, it couldn't. A male sea horse has a pouch of which carries females eggs and it fertlizes from inside of him. In no way does he use his rear where poop comes from..And only poop.
You also said he gets no period, every thing has a period...Or else the vaginal wall (which would never be clean seeing how shit would be in it and the male would die from serious infection) would stay filthy and most likely rot due to no inner lining or anything keeping it functional. Also, the male would get extremely constipated by how the baby would crush his anus wall outwards and would loose bladder control.
So in all honesty, the theory is very flawed and if anyone in a fanfic attempts to make this romantic...Eh..It's honestly just dreadful and most likely painful...No one could live from that...All those infections, the loss of control over poop and pee...Erugh...
