In the comics and animated series, Steve Rogers fathered two children in alternate timelines who had his super-soldier abilities. Though the mother of these children was not Peggy Carter, it does imply that Captain America's children in the MCU would most likely inherit his powers.
The writers of "Avengers: Endgame" confirmed that Steve is the father of Peggy's children and that they likely have super soldier DNA. While Steve's children have not appeared in the MCU, in alternate universes he has a son named James Rogers and a daughter named Sarah, both of whom inherit his superhero abilities.
Surviving the war and believing Rogers had died during his last mission, Bucky eventually married Rogers' fiancé, Peggy and had two children, Marvin and Rebecca.
The super soldier serum is supposed to heal a person from all things that can harm the body and prevent anything that would effect a normal person on the cellular level, and slows aging in the comics context.
During the Season 1 finale, it is revealed that Peggy – who has put on a considerable amount of weight over the course of the season – is pregnant with Pete's child. She gives birth to a boy.
Peggy is pregnant, though nobody knows it, with Pete Campbell's child. She has the ability to generate more than images and ideas; she is potentially producing a family and a home.
Bucky owes his youthful appearance to repeated cryo-freezes orchestrated by the Russians. He possesses no super powers and never received a form of the Super Soldier Serum as many assume, but continues to operate at peak human ability.
Bucky Survived Through Cryogenic Freezing And The Super-Soldier Serum. After surviving his fall from the train, Bucky would be kidnapped by a HYDRA cell in the Soviet Union, and then placed in the same super-soldier experimentation that Steve was.
Taking the experimentation, cryogenic freezing and time skips into consideration, Bucky is physically somewhere in his mid-30s by the time The Falcon and the Winter Soldier takes place, making him appear seventy-some years younger than his chronological age.
One of the greatest reveals in the MCU was dropped when Black Widow explained that, due to the particulars of her training and backstory, she was as incapable of having children as Bruce Banner.
“Sam and Steve had a relationship where they admired, appreciated and loved each other,” Mackie said. “Bucky and Sam have a relationship where they learn how to accept, appreciate and love each other. You'd call it a bromance, but it's literally just two guys who have each other's backs.”
The Super-Soldier Serum dramatically prevents individuals from aging due to the regeneration of healthy cells. For instance, Dr. Kudrin has stated that Natasha "don't age as fast."

Bucky was born on March 10, 1917, so he was already older than Steve, who was born on July 4, 1918, even before they became enhanced. Further, Captain America was frozen and preserved as he was in 1945 without thawing for nearly seven decades before he was revived.
The fact that Bucky did wear the arm is why it disappeared according to the Russo brothers (via Comicbook), as they stated anything that was part of someone's identity would disappear when snapped.
They clearly succeeded in Wakanda because the next time he showed up, he was living in a hut in Wakanda, and the kids living around him nicknamed him the White Wolf. This nickname was just something the kids gave him, as Shuri (Letitia Wright) still called him by his real name.
In terms of raw strength, Captain America is typically portrayed as being stronger than the Winter Soldier, although the Winter Soldier's combat skills and agility can still make him a formidable opponent.
Chronologically Cap is 66 (the years he was frozen) add his “true” age of 39, giving us 105. After the jump to 1945, he presumably lived until 2023, which gives him an added 78 years to both of his ages. So overall, biologically Steve is 117, chronologically he's 183.
(This is the episode that ends with Betty shooting BBs at their neighbor's pigeons.) Peggy's rapid weight gain (actually her pregnancy, though she and the audience don't know that) has caused her to rip her skirt, and a surprisingly magnanimous Joan offers her a spare dress to change into.
Did you know. It is revealed that the previous episodes of season 6 were all a dream. Katey Sagal had miscarried in real life, so the writers decided to get rid of Peggy and Marcy's pregnancies.
One of the many reasons why Peggy started resenting Don over the course of the show is the fact that he never really thanked her for her contributions, and took credit for her work, at times, as well.
