Sparklings. Can't just fuck spill transfluid and leave, as funny as that may be One needs to merge, doesn't matter how deep it is as long as the two sparks are touching (However the deeper the merge the more likely a sparkling can form if said carrier has a full forge.)
Anyways when a Sparkling has been nestled into said carriers spark They are called a Sparklet, this is the most delicate stage of a bitty as at any point during their time around their carriers spark they can get reabsorbed. This can happen if the Carrier is hurt, stressed, Or there is not a good amount of food to sustain both carrier and Sparklet.
If the Sparklet survives during their 2 month time nestled close to their carriers spark. Then month 3 they can officially be classified as a Sparkling. So what happens next? well during the third month the Sparkling will take it's time to detached from their carriers spark and decent down into Their carriers first forge which is normally directly underneath the Carriers spark. There they will remain until they are ready to emerge.
So now what did i mean by first forge. Well. The first forge is to house the bitty. The secondary forge is what's connected to the carriers valve, and it's what supplies the transfluid for the bitty. But now that the bitty is ready to emerge, The Bitty needs to travel down to the secondary forge. It is a stressful process for the Carrier almost as bad as a spark break because this is when the bitty fully disconnects from the Carrier.
Once emerged the Bitty will use the sire's transfluids and the energy from the carrier to form it's own protoform and metal.

Transformers One Soundwave's kids Headcanon(pre movie)
Having grown up in an orphanage, Soundwave had always hoped he would have a big family.
The orphanage was both funded and well run, and Soundwave made frequent donations to it as an adult.
-Had Soundwave seen what the orphanage had become during Setinel's reign, he would have kidnapped the orphans, beaten the caretakers and then would have watched it all burned to the ground.
Soundwave would later belive that an alt mode surgery he had as an young bot render him sterile.
Soundwave would adopt Lazerbeak, Buzzsaw, and Ravage simultaneously after a High Guard mission.
-Soundwave had to fight to prove that they were sapient mech, and that they deserved the designation of "sparklings" rather then tools or pets.
-Lazerbeak and Buzzsaw are twins, and a little older, but Ravage is considered the leader of Soundwave's sparklings.
Ratbat was named after Senator Ratbat, a senator Soundwave has had...hostility with.
-When asked why, he said "Because Soundwave's Ratbat will always be good Ratbat by default.
-This made Shockwave laughed so hard everyone thought he was having some sort of processor attack(Cybertronian equivalent of a stroke?)
Soundwave believe he couldn't get sparked, so Rumble and Frenzy's emergence was a great surprise.
-It was also a surprise to everyone else, for it had happen during a High Guard strategy meeting
Sons: Buzzsaw, Rumble and Frenzy.
Daughters: Lazerbeak, Ravage and Ratbat
Everybot agrees that Soundwave isn't...all that great at naming his sparklings.
-Soundwave is/was called "Upbringer" ( a popular term for adoptive parents), at least until they all had to go the surface...

Mech Pregnancy, Cybertronian biology and the gestation system, and what I like to call the Gestational Protocols
(A sparkling has two parts: The spark and the birth metal).
I have written about mech pregnancy before and that actually went really well! It got over a hundred notes, my most popular post ever.
So I thought, why stop? I love reproductive science. I love science fiction. I want to develop this more.
I spent more than five hours drawing and labeling and I am not fully pleased with it, but I am just pleased enough and tired enough to show you all what I am thinking.
If mech pregnancy, breeding, world building and/or messy hand drawings bring you joy, check below the cut!

(When I say I drew these by hand, I mean I drew them by hand).
(Note: When I mention a CPU, I am referring to a Central Processing Unit, otherwise known as the brain module.)
The codpiece: A goddamn problem. They can transform into transportation, though, so moving a codpiece out of the way surely has to be doable for them.
The valve: It has very large and noticeable exterior energy node and the reason for this is to indicate charge. We see the portus majora, or the larger port from the outside. If we spread these folds, we'll see the portus minora, or the smaller port. The portus minora is where the interior node system begins. Within the portus minora is the valve entrance, which gives way to the valve sleeve.
The spike: It can be modified or replaced, but the design has to be such that it can collapse in on itself and fit inside of the housing. Whatever your personal preference, the plug (the head of the spike) should expand outward in some way for reasons I will explain shortly. The plug is densely populated with small interior nodes while the cord or cable (the shaft of the spike) is sparsely populated with large exterior nodes. This makes the plug more sensitive. When the cable drains of its gel (which is recycled back into the system via a pressurizer fluid reservoir), these exterior nodes sink into depressions within the interlocking segments so that they don't snag on the housing rim when depressurized.
Note: In the diagrams, I call the nodes "energy nodes". There is a reason for that, but it's not necessarily necessary to the system.
Let me explain: I wrote a story where the nodes captured energy from the friction of the spike's external nodes striking against the valve's internal nodes and then that energy was sent to the spark chamber as a backup source of power during spark merging as spark merging dispersed energy and thereby diminished the sparks.
They don't have to be energy nodes, though. Those fun little goodie spots that create so much pleasure don't have to have a dual purpose. They can just be sensory nodes connected to the sensory net, a subsystem of the neural net.

When it comes to spark merging, I use stellar collision to visualize it. Here is a Youtube video that shows the collapse of a binary stellar system that pretty much sums up what I think happens, but on a much smaller scale: https://www.youtube.com/watch?v=zsIMDKMKUWw
The result of the spark merging, however is that a third body is generated from the collision. This third body is created from the intense heat and energy of the spark merging, and from the fragmented copies of life codes duplicated during the spark merge. This is the sparkling. When its creators' sparks retreat to their own chambers, the sparkling will attach to the creator that is receiving transfluid (I will explain shortly).
A form of gestation control includes putting a shunt on the spark chamber to disperse the foreign energy body.
2. The birthing conduit is what it says it is. Once the sparkling has created its own life code, it will descend down the conduit and join with its birth metal, or sentio metallico, in the gestation tank.
3. The gestation tank is where the birth metal is produced from the metal alloy particles carried in transfluid and the energon provided by the carrier. You can also think of it as a crucible furnace, which is used for melting metals in small quantities within a foundry. The crucible is the innermost cavity where the birth metal is made. That crucible is lined with a layer of refractory material, which withstands high heat. That refractory material is going to keep that crucible hot enough to maintain the birth metal as a liquid without melting the protoform layer between the refractory material and the outer shell of the tank.
So the layers from outermost to innermost are :
Outer shell -> protoform layer -> refractory material -> crucible
Also, I move to call the carrier creator a foundry now because I love that word so much. The Google definition for a foundry is a workshop or factory for casting metal. It just sounds so good.
"Hey, First Aid, is Ratchet your foundry?"
"No, but I get that a lot."
I can't think of an equally cool word to replace the term "sire".
4. The valve sleeve is a semi-permeable layer of elastic protoform that can stretch to a certain degree. The interior nodes are within this protoform layer and creates a bumpy texture. As already discussed the sleeve is self-lubricating. I am starting to realize that I labeled this diagram horribly, but please bear with me.
5. Calipers! They in all the sticky sexual interface stories. I just imagine them as these segmented, arm-like extensions that squeeze and relax depending on stimulation. In fanfiction, they have a habit of "cycling down" whenever stimulated. What I love about calipers is that they do set a minimum and maximum range of flexibility for the sleeve. With calipers, there is such a thing as being too small (the calipers can only tighten so much) or too big (the calipers can only loosen so much). They are synonymous to the pelvic floor muscles in a human that makes a vagina contract and relax, but they just make me think of pussy bones. You have to be careful not to break them.
6. THIS IS MY FAVORITE PART. Here is where the valve sleeve meets the gestation tank. There are two orifices: The tank cap and the lockring. The tank cap is where your mech is going to put some kind of seal as a form of gestation control. If a spike can't get into the gestation tank, then there is no birth metal. If there is no birth metal, a signal will be sent to the mech's CPU and then to the spark chamber to disperse the potential sparkling. How the tank cap is removed depends on how you want it removed. If you want a screw-in cap, then that cap will have to be removed via an invasive procedure (otherwise known as we're going to have to stick this instrument up your valve and twist the cap open and then we have to pull out the cap). If you want almost any other kind of seal or door, you can hypothetically just send a signal from the CPU to the neural net attached to the gestation system and have that seal slide out of the way into a depression within the rim of the gestation tank.
BUT THAT LOCKRING, THOUGH. This is why your spike needs to have a plug that expands to some degree.
Once that cap is out of the way, the mech's spike is going to pop through that lockring, sticking their plug directly in their partner's gestation tank. I like to call this "plugging the tank". Once that plug is in that tank, a signal is going to hit the CPU to start up GESTATIONAL PROTOCOLS. More on that at the end.
That lockring is going to cycle down just behind the plug, tight enough that the spike can't pull out without being too tight.
The purpose of this is to ensure that the gestation tank is filled up with transfluid. The lockring will only cycle open once the tank is full or once sensors within the tank indicate that the flow of transfluid has stopped for a certain amount of time (meaning that there is no more transfluid to be had, even if the tank isn't full yet).
It's a reverse knot! Instead of having a spike that knots, we get a valve that locks! I love it so.
7. The energy - or sensory - nodes are part of a positive feedback loop, meaning that "the product of a reaction leads to an increase in that reaction" (https://www.albert.io/blog/positive-negative-feedback-loops-biology/). In this case, pleasure created from stimulating those nodes (such as friction) encourages more stimulation, which creates more pleasure, which encourages more stimulation, until the loop breaks. What breaks this loop is overloading the sensory net or removing the friction.
When we state that the valve is self-lubricating, you can decide for yourself how it does that. The trick is making sure that the mech can can replace their own lubricant when necessary. One system is to have lubricant be a type of consequence from energon circulation.
Humans self-lubricate their vaginas in several different ways and one of them is that the vagina is somewhat permeable. Plasma (the liquid part of blood) is able to discharge from the bloodstream through the walls of the vagina.
Or perhaps your lubricant comes from the same reservoir as the transfluid for your spike. Since the valve sleeve is only somewhat permeable, the metal alloy particles in your transfluid can't get through. What does leak through is the fluid medium that the metal alloy particles reside in.

The plug is itself not an interlocking segment because the plug, as explained, has to expand so that the lockring can tighten between the plug and the topmost interlocking segment. If the plug is smaller than the interlocking segment behind it, then the lockring will either not tighten enough or will tighten too much. Instead, the plug has an outer protoform layer that is expanded with the same pressurizer fluid that fills the spike. In the diagram above, we see the spike, the spike housing that the spike has to depressurize to fit inside of, and at least three different connections at the bottom. One of these connections bundles the wires for the sensory net and attaches to the neural net.
The bottommost connection is to the pressurizer fluid reservoir. When the spike is pressurized, the reservoir compresses and fills the matrix within the spike to give it its form and rigidity. When the spike depressurizes, the reservoir decompresses as it fills with fluid.
The connection that has a dashed line going all the way up the spike connects the transfluid reservoir to the transfluid line (signified by the dashed line) and out the plug. The transfluid reservoir is actually pressed against the outside of the valve!
So it is possible to bang a mech's valve so good that they leak transfluid all over themselves because you are more or less hitting their reservoir with every thrust. You just have to get the angle right or else you're hitting the sleeve calipers and that might not be as fun.
The Gestational Protocols:
This has turned into a very, very long post. I have been working on it for nine hours now between drawing the diagrams, writing the post, and checking with Google to make sure my science isn't horrifically, unforgivably wrong (I could be using the positive feedback loop wrong, but I don't think I am).
So let me wrap this up with the Gestational Protocols. It's like a mech heat fic, actually, except the heat is very short and starts toward the end of sticky sexual interfacing.
For this scenario, Ratchet and Drift want to produce a sparkling. Because Drift is concerned about Ratchet's health, they decide that Drift should be the foundry. Drift has his tank cap removed beforehand.
They're having a great time, creating all the good friction, lighting up their sensory net like a growing fire. Drift is charged up, Ratchet is charged up, and they're about to hit that overload.
Drift's lockring is cycled all the way open. His calipers are trying to pull Ratchet closer. When Ratchet knows he can't hold on any longer, he pushes as deep as he can go. There's a small moment of resistance when his plug meets the lockring and then he pops through. The lockring cycles down and he's stuck. There's no pulling out now.
Ratchet told Drift what to expect from the gestational protocols, but it wasn't enough. The moment Ratchet is locked in place, a signal is sent from his gestation system to his CPU: Gestational protocols initiated...
His cache memory crashes. He has no past or present or future. He has no idea there was a war lasting millions of years. He doesn't even know what a Cybertron is. Programs are halted, tasks are paused, processing units block external input. Hydraulics fall to the lowest power possible. His frame goes completely limp.
Drift no longer exists. He is now a foundry. He is the function of his gestation system. His CPU has a primary and secondary task: Primary is to maintain the protocols and secondary is to reward Drift for maintaining the protocols.
As long as he lays there and lets Ratchet fill him up, he's fulfilling his primary task. Because it's so easy to let Ratchet fill him up, his neural net rewards him with pleasure and feel-good signals. He is riding a type of euphoria that is thoughtless bliss from the tips of his pedes to the tops of his finials.
A task pops up in his CPU, but he doesn't have the processing power to interpret it. He accepts without caring. He experiences his chest plates cracking open without actually seeing it or hearing it. His system rewards him for accepting the prompt, so he still doesn't care. His spark chamber opens next and he is thrown into the intense, beautiful pleasure-agony of having his spark collide with another mech's spark.
He doesn't remember who this other mech is, but Drift loves them. They're filling Drift up so well, both his tank and his spark. He's so full. He's being such a good foundry. He's receiving all those good neural and sensory signals and he's fuzzy/fizzy with joy.
The spark merge ends after several collisions and spirals. Drift loves every moment of it, and also loves it when his spark returns to its chamber. Now his spark feels swollen and his CPU registers a foreign body. There is a potential sparkling attached to his core. Chances are very good that this potential sparkling will not disperse.
His CPU rewards him with another rush of emotional glee and pride. He's sparked! He did so well, laying there and letting himself get sparked. He's a great foundry. He's the best foundry to ever get sparked. No one has ever been or will ever be as well-behaved as he was.
A notification hits his CPU and he doesn't even try to understand it. Apparently, it's the notification for his tank being full. A second notification and his lockring relaxes. He is deliciously, fully aware of a thick spike dragging across his oversensitive interior nodes, sending one last wave of hot, crackling pleasure through his frame.
Another notification. He doesn't read it. A task pops up. He accepts lazily.
The notification was that the gestational protocols had been completed. The task was to enter a soft reboot. Drift slips into recharge feeling like his only purpose in life is to embody pleasure and creation.
He wakes up feeling swollen and sloshy.
Ratchet is smiling down at him.
"Am I...? Are we...?"
Ratchet stroked a servo across his chest plates. "It's early still. The spark might disperse. But chances are looking good. We're sparked, kid."
And that is how I imagine the Gestational Protocols going: You get your tank plugged and then nothing matters but getting filled up with a sparkling.
Thank you for reading my book-length discussion! Please feel free to interact with me.
I have been working on this for ten hours now. I should proofread, but I am not going to at this time.
EDIT: I was in the shower when I realized I forgot something important - where does the protoform's first colony of nanites come from?
@earthstellar explains here (https://www.tumblr.com/earthstellar/659541951144738816/transformers-medical-analysis-essay-what-are?source=share) what Cybertronians use nanites for, including construction and self-repair. So we can readily assume that the protoform needs a nanites colony.
I'll tell you where the new spark's nanites came from: Their foundry's valve.
Humans do the same thing. We pick up friendly bacteria from the vagina we come out of.
That is all I had to add. Remember to start your protoform off right with a healthy nanite colony.

I love this trend of designing (animated) Optimus as breedable. TFA? That hip to waist ratio. TFP? Same but he comes with built in handlebars for backshots. Even Bayverse Prime has his ridiculous cheerleader outfit showing off his tits and thighs.
TF1 Orion Pax though is the most breedable simply because he gives off major “freak” vibes.
tfa op: His entire build, but also slut lips that are waiting to be kissed when being stuffed full of transfluid.
tfp: smoke stakes on the back that Megan can grab as he's plowing Op from behind.
bayverse has fire details on his tits, and he sports a loincloth going over his mother bearing hips. Op can sit on Megans spike and no one would know bacuse loincloth is in the way.
tf one op just being a freak is 100% a reason for him to be breedable. plus he's a brat that D-16 needs to tame by fucking a litter into him.

Rodimus is pregnant after a pitstop on Earth and everyone on the Lost Light is sooooo curious, wondering who the sire is. There's bets that it's either Dratchet's or MiniMeg's or even Thunderclash's because Rodimus is keeping a tight lip on the identity of the sire. And even though they're not the sire/s, they do try to court Rodimus to help him but he gently turns them down.
But surprise! It's actually Soundwave from a one night stand they had on Earth. Not only that but he comes to the Lost Light to woo Rodimus, who thought Soundwave was only interested in his frame but that's far from the truth. He wants to properly court Rodimus and be a family with him.
Rodimus had tried to keep it a secret but after passing out on the bridge his secret was revealed.
He was just coming around when he felt Ratchet scan him and then the medic gasped.
"You're sparked."
Those who'd been waiting for him to wake up also gasped and when he turned on his optics he blushed feeling a little embarrassed that his secret was revealed like that.
"I know."
He didn't say anything else even when people asked about the sire.
Word spread throughout the Lost Light and everyone began placing bets on who the sire was since Rodimus hadn't said anything.
Some thought it was Drift or Ratchet because he was close to them especially Drift. While others pointed out that Ratchet didn't like him and had voted against him as captain.
Other people thought it might have been Megatron or Minimus. While others argued heavily against Megatron being the sire and others thought the couple wouldn't want someone like Rodimus who was the exact opposite to them.
Then someone mentioned Thunderclash and for a while everyone was placing bets on them because who wouldn't love Thunderclash.
Out of all the bets Rodimus hated that one the most. However none of them were right.
He'd been joking about it with Drift until his friend got a serious look on his face and asked him who it was. He'd merely changed the subject refusing to talk about it anymore.
This seems to make his Amica worried because he begins courting him with a reluctant Ratchet. Both of them wanting his sparkling to have a sire.
He didn't even have to think about it before turning them down. However they weren't the only ones who wanted to "help."
Both Minimums and Megatron tried to prove they were worthy of being the sparklings sire. However he refused asking them both to stop.
Thunderclash was a lot harder. He was determined to be the sparklings sire and it was made harder by everyone thinking they were a cute couple. He hated it so much and silently fumed when people talked about what a great guy he was and how his sparkling was so lucky.
Thunderclash followed him around everywhere constantly trying to take care of him even when he could do things by himself.
He was getting tired of everyone bothering him and gossiping behind his back,bthat it was making his carrying so much worse.
He'd just spent the morning throwing up in the bathroom when he heard shouting. He rushed out to see what the commotion was about and found Soundwave coming towards him.
His crew was trying to stop him but Soundwave shoved them out of the way demanding to see him.
"What are you doing here?"
Around him people froze letting Soundwave pass.
"I heard you were sparked."
He blushed glaring at his crew for gossiping so much it got all the way to Earth.
"Is the sparkling mine?"
Unable to deny it he nodded.
"Yes."
Around them people gasped.
"Why didn't you tell me?"
"I didn't think you'd want them."
"Of course I'd want our sparkling."
"I thought I was nothing more than a one night stand."
"I don't sleep with just anyone."
Soundwave reached out his hands gently stroking his face and he leaned into his touch.
"You are so much more than a one night stand and I've been trying to reach you even before I learned you were sparked."
He felt tears in his optics and Soundwave wiped them away. Around him people were aweing and he pulled Soundwave into his room so they could talk by themselves without everyone listening in.
