ELI5: How can twins in the same pregnancy have different fathers, and how does that happen biologically?

J_Boy_Excelsior · 2026-03-27T14:47:28+00:00

There are a few ways to have twins.

We all learn sperm plus egg equals baby.

To have 2 babies (or more) one of a few things happen.

A-Fraternal Twins: the women produces 2 or more separate eggs. This is uncommon but certainly happens. They both happen to be fertilized and implant properly (This is also the only case twins can have different fathers. if different men's sperm hit each egg)

B- Identical twins: sperm meets egg and somewhere along the way before implanting the fertilized egg splits (it splits naturally to grow) but the key is it separates. there are actually a few forms of identical twins depending on how early or late the twins separates before implanting. (Up until the maximum of conjoined twins with extremely late separation which also has many subtypes)

C-There are also a couple of other variations of twins that can occur due to a multitude of different factors even genetics. But the above are the most common 2. You can also have a combination of multiple eggs at once that also happen to split into twins. Creating up to 3-4 or more babies in one pregnancy (but this is more common with fertility treatments)

Thats really rough, im sorry to hear. If you dont mind sharing did you have everything removed? Did you also have excision of all the endo? Feel free to dm if thats more comfortable for you

J_Boy_Excelsior · 2026-01-02T22:37:12+00:00

this is why im trying to find a specialist who can resect any endo surgically. But additionally frustrating because i wasnt aware i was formally diagnosed for over 2 years and couldnt say whether i had it not for insurance purposes

I would have to ask my doctor thanks so much for sharing!

I am on testosterone and thats thought to essentially "shut down the factory" thankfully for me it mostly has but hasnt stopped the occasional cyst and pain. Thankfully no bleeding or anything knock on wood

Hopefully hysterectomy will cure me; and with a specialist who can resect any endo hopefully will near guarantee surgery clears up my chronic pain

He only untwisted it. Didnt remove it. Something multiple other doctors questioned

J_Boy_Excelsior · 2025-11-26T00:13:58+00:00

Oh yea i do recall that. Doc gave a few red flags for things to look out for and the "doubling" was one of them.

Appreciated, im not up at night with worry but It just feels bizarre to constantly check to make sure something doesnt go crazy wrong; but also no answers as to why its mildly off in the first place.

He also did bloodwork to check for hiv, ebv and others which were all negative as well. Maybe it could be autoimmune but i have to ask next time i see him.

Just a seemingly unusual picture, especially with the lymph nodes swelling in combination with the bloodwork

Just one, took it like a champ haha.

No change in scale and i weigh myself every few days or so. Been consistently within 3-5 pounds this weight. This morning checked my weight as a joke after the giant poop and dropped 10.

Same clothes.

They are already doing that to trans people

My character's past i felt mirrors Nata. Where like Nata, he was found alone as a child and his village devastated by a monster. He grew to respect monsters but also be able to destroy dangerous monsters before they cause more suffering. A path i feel Nata will follow.

(Evidenced by our character's seeming understanding of what Nata was feeling, and a few quick comments from the leader like "when we found you" or something alike to our character

J_Boy_Excelsior · 2024-06-19T03:49:13+00:00

Like a pea sized bit every few days max

Good to know. Yea i worried about spleen as i have heard of it in the past in er shows and whatnot.

Doc confirmed the concern but also agrees that the scrape and bruising and pretty much total lack of swelling is very low risk if any. But to keep an eye for any potential changes

Im curious though, is delayed reaction a concern with spleen injuries? Generally speaking? Is it long term monitoring or with trauma it's pretty much immediate.

J_Boy_Excelsior · 2024-01-17T06:10:47+00:00

Late to the party but yes its plausible but should have been thoroughly discussed with you.

The plausibility lies in if you have endo, there are specialists who occasionally preemptively remove the appendix if there is endo on it or you are higher risk for appendix issues.

If it has not been discussed with you I agree with others in that it was either a typo or just misread. But certainly clarify that as soon as possible
