He wanted a new head but had a change of heart — after his glamorous new wife gave birth to their “miracle son,” according to a report.

Valery Spiridonov, who suffers from a muscle-wasting disease, had volunteered to undergo the world’s first head transplant at the hands of Italian surgeon Dr. Sergio Canavero, who is dubbed “Dr. Frankenstein.”

But the 33-year-old Russian — who is studying the computer analysis of emotions at the University of Florida — recently revealed that with him are his bride, Anastasia, and their recently born son, the UK’s Sun reported.

The boy, whose name has not been revealed, was born six weeks ago and is healthy, which Valery considers a “miracle” since the rare genetic Werdnig-Hoffman disease his dad suffers from can be inherited.

Anastasia, who holds a master’s degree in chemical technology, underwent tests during her pregnancy.

She is not seen in pictures with Spiridonov, but she explained online her love of men in wheelchairs.

“Such people are much deeper, feeling, faithful, kind-hearted, and also they are usually very smart… isn’t that the main thing?” she wrote.

Her husband said they tied the knot “a little over one year ago in Moscow.”

“We lived in the same city, and often met on professional matters and soon realized that we felt really good together,” he said.

In 2015, Spiridonov said, he realized the risks of having his head severed and reattached to a new, healthy body — but that he was prepared to sacrifice his life for science. He did have some requirements, though.

“I wouldn’t want to have my head transplanted onto the body of a woman. When I wake up, I still want to be a man,” he said at the time.

Canavero, who has claimed to have successfully carried out such a surgery on rats and a monkey, is now working in China, where he has received funding for his research, the news outlet reported.

Spiridonov has challenged the surgeon to come clean on his efforts in China amid suspicions that something went awry during tests on two bodies.

“I do not regret it that Canavero did not reach the final goal — or did reach it, and failed,” he told the Russian newspaper Komsomolskaya Pravda.

“This was just a normal working process. The only thing we lack from him is more publicity,” he said. “Everybody would have benefited from information about what went wrong in China and why.”

He added that he never had a “vain motive” in seeking the transplant.

“I feel a weight lifted off my chest,” he said. “I gave two years of my life to this project. I will be glad to see it happening [with someone else].”
