The Prime Minister Seduced Me to have Babies!-Chapter 613: Attending a Physiology Lesson

Jiang Zhongxing sat down with a dark face, "Last time you took my pulse, you said I was healthy, but I want to know where the problem really lies." He pressed his hand down, "Sit down and speak, it’s fine, no matter what, just say it."

Yun Jiao said, "I suddenly thought of something today—it’s a substance that, when consumed for a long period, doesn’t harm the body in other ways but can kill sperm, leading to infertility."

Upon hearing this word, the couple had some guesses, after all, it sounds very similar to ’semen’.

But seeing Yun Jiao’s calm expression, they became unsure.

If it really were the case, a young lady would surely be shy to speak about it, right?

Moreover, they didn’t quite understand the meaning of ’kill’ in this context; that thing couldn’t possibly be alive, could it?

The couple looked at Yun Jiao and asked in unison, "What is sperm?"

Yun Jiao opened her mouth slightly, raising a hand to her forehead—well, oh dear. Is she supposed to be giving future in-laws a lesson in biology right now?

She took a deep breath, "This—people are able to reproduce, firstly, starting with sperm, inside the male body... then the egg... then the fertilized egg..."

The couple, like two schoolchildren, listened with half-open mouths as she gave them a lesson.

At first, the couple felt awkward listening to a young lady talk about these things, but because Yun Jiao spoke so seriously, their embarrassment faded, and they listened earnestly.

What none of the three expected was that Jiang Youzhi was also standing outside the door listening to the lesson.

Earlier, he went to Yun Jiao’s courtyard to find her, the maid said she had gone to the main courtyard, so Jiang Youzhi followed her there.

The maids were all in the courtyard and said Miss Gu was in the room talking with the Duke and Duchess, so Jiang Youzhi directly went in, and the maids didn’t dare stop him.

Even the main maid didn’t dare to stop him.

Upon reaching the door, Jiang Youzhi heard Yun Jiao’s words, and his steps hesitated.

He would never admit that he just wanted to eavesdrop; he stood by the door, blushing, ears perked up, looking much like a student attending their first health education class.

Yun Jiao continued speaking a long stream of words, feeling she had explained quite clearly, and said, "Okay, I’ll continue with the previous matter."

The Duke and his wife exchanged a glance, but we still want to hear more about this—it feels like a door to a new world has been opened.

However, neither dared to voice this sentiment.

"There are some foods that can kill sperm, like celery and tofu, which have a certain sperm-killing effect but wouldn’t lead to infertility."

"There are a few medicines that can also kill sperm, but upon careful thought, these medicines have strong smells; if the Duke had taken them, he would surely have known, and these medicines either damage kidney function or can be restored over time after stopping use."

"Considering the Duke’s current condition, after pondering left and right, there might be only one possibility."

"The vegetables that the Duke eats might often be cooked with cottonseed oil."

"Cottonseed oil has a strong sperm-killing effect, and prolonged use can kill off sperm completely, making it naturally impossible to conceive."

The Duke and Lady Wu exchanged a glance, "I’ve never heard of this thing, is it edible? Does it have any other harm?"

Yun Jiao shook her head, "It doesn’t really have any other bad effects; logically speaking, after stopping use for a period, recovery is possible."

The Duke became somewhat excited; he wanted Lady Wu to bear him a daughter again, which means there is still hope.

He stood up abruptly, "I’ll have someone investigate immediately!" Then he strode out.

Upon exiting, he nearly bumped into Jiang Youzhi.
