Chapter 749

Rejection reaction?

When Yu Dazhang heard this term, he froze, a flood of questions flashing through his mind.

Mainly because he didn’t know whether a rejection reaction was normal during surrogacy.

This involved professional knowledge—he, as an outsider, had no way to make an accurate judgment.

From his expression, Hua Dui guessed what he was thinking.

“I’ve already asked relevant gynecological experts.”

Hua Dui explained seriously:

“The placenta has a membrane on its surface; the doctor said this can be understood as a natural barrier.”

“Therefore, although the surrogate mother has no genetic DNA connection with the fetus, the placental barrier keeps the fetus’s and the mother’s circulatory systems separate.”

He took a deep breath and summarized:

“So the fetus will not be rejected by the surrogate mother.”

He explained in great detail, and Yu Dazhang understood.

In short, it came down to one sentence: no rejection reaction occurs during surrogacy.

“The doctor’s meaning is…”

Yu Dazhang confirmed again:

“The placenta and the mother have two independent circulatory systems?”

His current learning ability was not something an ordinary person could match—he grasped the key point after just one hearing.

“Yes.”

Hua Dui was surprised by Yu Dazhang’s quick reaction—he himself had spent over ten minutes just to understand it when talking to the doctor.

“Then what causes the rejection reaction?” Yu Dazhang pressed.

Since it wasn’t caused by surrogacy, there must be another reason.

And from Hua Dui’s tone, this wasn’t an isolated case.

Many women had shown the same symptoms—it had to be deliberate.

“We don’t know yet. The doctor said further tests are needed.”

Hua Dui said helplessly:

“Because the number of affected women is so large, the preliminary checks aren’t even finished yet. We’ll need to wait for the follow-up results—earliest possible is tomorrow.”

It was clear he was anxious, but there was no use rushing—only after the hospital completed the tests could they know the exact situation.

Could it be a misdiagnosis? On this point, Yu Dazhang knew a quick way to tell.

He thought for a moment, then asked:

“Was the diagnosis of rejection reaction given by one hospital, or by multiple hospitals simultaneously?”

If only women treated at one hospital showed rejection reactions, while others didn’t, it was highly likely that hospital was at fault.

Since these women were randomly assigned to different hospitals, their diagnostic results should be roughly consistent.

“All hospitals that treated them reached the same conclusion.”

Hua Dui answered with a grave expression:

“When I said many women had rejection reactions, that was actually a conservative estimate.”

He paused, then continued:

“According to hospital feedback, every single woman who underwent the relevant examination showed rejection reactions.”

“Since the preliminary checks aren’t fully completed yet, I used the word ‘many’ to describe it.”

Hua Dui took another deep breath and went on:

“Under these circumstances, any woman who underwent surgery will eventually show the same symptoms.”

Yu Dazhang nodded, his frown deepening.

That ruled out misdiagnosis.

With so many hospitals giving identical diagnoses, it meant these women’s rejection reactions weren’t accidental.

But the problem was, placental transplants don’t trigger maternal rejection.

If that’s the case, then what exactly is the mother’s body rejecting?

Were organs being transplanted into these women’s bodies?

Although Yu Dazhang had no medical knowledge, he understood the general cause of rejection reactions.

In short, it’s an immune response triggered when the immune system identifies and attacks foreign transplanted tissue or organs.
