Jiang Zhongxing sat down with a dark face, "You gave me a pulse last time, saying that I was in good health, and I also wanted to know what the problem was." He pressed his hand down, "You sit down and say, it's okay, whatever, you just say." ”

Gu Yunjiao said: "I also suddenly thought of it today, there is a thing, long-term consumption, which has no other harm to the human body, but can kill sperm, resulting in infertility." ”

As soon as they heard this word, the couple had some guesses, after all, they were very similar to Jingyuan.

But seeing Gu Yunjiao's expression so calm, they were not sure again.

If that's the case, the girl's family will always be shy to talk about it.

And they don't quite understand the meaning of this killing, that thing can't be alive, right?

The couple looked at Gu Yunjiao and asked, "What is sperm?" ”

Gu Yunjiao opened her mouth and reached out to support her forehead, what is it, oops. Is she going to give her future in-laws a physiological hygiene lesson now?

She took a deep breath, "This, the reason why people can be conceived starts from sperm first, in the male body······ Then the egg ······ Then the fertilized egg ······"

The couple were like two elementary school students, with their mouths half open, listening to her teach them a lesson.

The couple was embarrassed to listen to a little girl say this at first, but Gu Yunjiao said it so seriously, their embarrassment disappeared, and they all listened carefully.

What the three of them didn't expect was that at this moment, Jiang Youzhi was also standing outside the door to listen to the lecture.

Just now he went to Gu Yunjiao's courtyard to look for her, and the maid said that she had come to the main courtyard, so Jiang Youzhi followed.

The girls were all in the yard, saying that Miss Gu was talking to Grandpa Guo and Mrs. Guo in the house, Jiang Youzhi went straight inside, and the maids didn't dare to stop him.

Even the big girl is not easy to stop.

Walking outside the door, Jiang Youzhi heard Gu Yunjiao's words, and he couldn't step in.

He would never admit that he was trying to eavesdrop, and he stood by the door with red ears and ears erected, like some students were taking a physiology class for the first time.

Gu Yunjiao said a lot in one breath, and felt that she had said it clearly enough, so she said, "Okay, I'll continue to talk about the previous incident." ”

Grandpa Guo and his wife glanced at each other, but we still wanted to hear you say this, it felt like opening the door to a new world.

It's just that neither of them is embarrassed to say it.

"There are some foods that can kill sperm, such as celery tofu, which have a certain spermicidal effect, but they do not cause infertility."

"There are several medicines that can also kill sperm, but, I thought about it carefully, these drugs have a big smell, if Grandpa Guo eats it, it is impossible not to know, and besides, these drugs will either destroy kidney function, or after being stopped, they can slowly recover."

"According to the current situation of Grandpa Guo, I think left and right, maybe there is only one possibility."

"The dishes that Grandpa Guo eats on weekdays are probably cottonseed oil."

"Cottonseed oil has a relatively strong spermicidal effect, long-term consumption of cottonseed oil, sperm are killed, naturally there is no way to have children."

Grandpa Guo and Mrs. Wu glanced at each other, "I haven't heard of this thing, can you eat it?" Are there any other harms? ”

Gu Yunjiao shook her head, "There is no other harm, after being deactivated for a period of time, it stands to reason that it can be recovered." ”

Grandpa Guo was a little excited, he wanted Mrs. Wu to give him another daughter, so there was still hope.

He stood up stiffly, "I'll have someone check it out right away!" Then he strode out.

As soon as he came out, he almost collided with Jiang Youzhi.
