"Haha!" After listening to Geng Qian's words, Zhang Zheng and Yu Shiman laughed at the same time. really let them guess correctly, this little girl was really confused by Liu Ying.

"Sister Liu, I know the meaning of this boyfriend, but what does it mean that sperm cells can be produced in this body? Can this type of cell be produced in the human body? Geng Qian asked.

"This, forget it, you still have to let Brother Zhang explain this question to you, because he has studied medicine and is more professional in this knowledge, and his explanation should be more authoritative." Liu Ying kicked the question to Zhang Zheng.

"The so-called sperm cell refers to the cell formed by the primitive germ cells of the epithelial sperm tube of the testis of animals through multiple mitoses. It is the result of the second maturation and division of spermatozoa during the maturation of the spermatozoa to form functional spermatozoa. This problem is too professional and difficult to explain clearly in a few sentences. However, since this entry is placed under the word 'male', it means that only men produce sperm cells, and relatively speaking, women produce egg cells. Zhang Zheng explained.

"What is the relationship between sperm cells and egg cells?" Geng Qian asked.

After listening to Geng Qian's question, someone may ask, this little girl is already 22 years old, why don't you even understand this, is it really a mental problem?

In fact, in the era when talking about sex and lust and treating sex and love between men and women as a flood of beasts, there were more people who didn't understand this knowledge, not to mention the little beauty Geng Qian alone.

"Normally there is no relationship between them, and only when the sexes are fused can the two cells have a relationship." Zhang Zheng explained.

"Brother Zhang, how do the sexes integrate?"

"I said girl, don't you even know about the integration of the sexes?"

"All I know is that the sexes intersect, and I really haven't heard of gender integration."

"These two statements are actually the same, but my statement is more elegant."

"So how do these two cells fuse?"

"Yes, after the sperm cells are metamorphosed, they will form sperm that can swim. Child. After sexual intercourse between the sexes, when containing sperm. The essence of the child. Liquid into the female pubic vagina. After the Tao passes through the Son. The uterus, in the fallopian tubes, the same egg cells meet, sperm. The head of the child enters the egg cell, combines with it, and forms a fertilized egg, which returns to the uterine cavity through the fallopian tube to implant and grows and develops until full-term delivery. That's how the two cells fuse, girl, get it? ”

"The essence in the body of a boy. Son, how can I enter the path of a girl? Geng Qian asked a very difficult question to answer.

"Stinky girl, you, don't you even know the sexes? Can't you? Zhang Zheng said.

"Of course I know that."

"Since you know, don't you knowingly ask?"

"I know that, but I don't know how."

"Girl, you confused my brother, what do you mean by that?"

"I mean, I know that in general, but I don't know the details and how of that."

"Well, how can I explain this to you? Let Sister Liu explain it to you, Sister Liu is from the past, and she should know this problem better than me, a guy who talks on paper. Zhang Zheng kicked the ball to Liu Ying again.

"Phew! You kid is so experienced, how did you become a piece of paper. I said Xiaoqian, we are both 22 years old, why don't we even know this? ”

"I've never had this knowledge since I was a child, how would I know?"

"You are also saying that education in our country is really poor in this area. Actually, my sister is not easy to answer your questions. I ask you, have you ever talked about a boyfriend? ”

"There are a lot of men chasing me, but I've never had a boyfriend." Geng Qian replied.

"I said Xiaoqian, why did you mention your boyfriend again, it should be your boyfriend." Liu Ying reminded.

"Oh, I'm sorry Sister Liu, this habit will be really difficult to change for a while."

"That means you haven't kissed a man anymore."

"Well, I haven't talked about my boyfriend, where did I get to kiss him?"

"Since I haven't kissed on the mouth, I must have never had a relationship with a boy."

"Sister Liu, who said I didn't have a relationship with a boy?"

"Ahh You mean, you've had sex with guys? Liu Ying was surprised.

"Of course, it doesn't just happen, it happens every day. For example, one to perform a task, one to eat in the cafeteria, and one to ......"

"Stop, I'm not talking about this."

"Which one is my sister talking about?"

"I'm talking about sexual relations."

"Isn't this relationship between a man and a woman a sexual relationship?"

"you, it's not this kind of relationship, you're talking about a normal relationship with friends and colleagues, not a sexual relationship."

"What does it mean to have sex?"

"It's the kind of relationship that happens with a lover, like your boyfriend getting that thing into your body and so on."
