A Chastity-Reversed World Where a Man’s Worth Is Determined by His Penis Size and Sperm Quality - 1

Chapter 1: Prologue

ーーーーーーーーーーーーーーーーーーーー

What determines a man’s value? Appearance, personality, wealth, status… In the modern age, a man’s value is determined by these factors. But this world is different. Dick length and sperm quality are everything.

And into such a world, I was reincarnated with memories of my previous life.

“…Experts have pointed out that this year’s average erect size is expected to fall below 4 cm, making it physically difficult for half of all men to engage in sexual intercourse. Moving on to the next news item. The male-to-female ratio is expected to drop below last year’s, reaching an estimated 1 to 20…”

The morning news was playing on the car radio. I was Tsuyoshi Hasegawa. As of today, April 2nd, I had turned sixteen and I was also a first-year high school boy. I had memories of a previous life. That said, it wasn’t as though I retained my personal memories. I merely possessed general common sense.

As the news earlier had mentioned, this world was completely different from my previous one. Perhaps due to the imbalance in the male-to-female ratio, the concepts of chastity between women and men were reversed. Furthermore, the average erect size among men was 4 cm. The quality of sperm had also been declining year by year, and apparently only half of all men were capable of having children.

“I’ll come pick you up after the examination is over, so do your best.”

This man was my father. In this world, it was rare, but I lived in the same house as both of my parents. My mother was at work right now.

“Yeah. I know, Dad.”

On the right side of my father’s chest was a badge with the letters “C.B” written on it. Right. Today was the day of an important examination that would determine the course of my life. Every man who turned sixteen had to undergo it. This was the day their dick size and sperm quality were tested. Depending on the results of these examinations, one’s future could be decided.

While I was thinking about that, we arrived at our destination. The destination was the Male Protection Organization, commonly known as MPO. After thanking my dad for driving me, I entered the facility.

“Excuse me. I’m Hasegawa, and I have an appointment for an examination.”

“May I see your identification, please? …Yes. Hasegawa-sama, we have confirmed your information. We are preparing for your examination, so please have a seat in that room over there and wait.”

To calm my rapidly pounding heart from the nervousness, I took a deep breath. Based on the results of the examination I was about to undergo, I would be assigned a rank and depending on that rank, my life could be decided.

For example, if someone had E-ranked sperm quality and a B-ranked size, that person would likely end up working in the sex industry. If someone had B-ranked sperm quality but an E-ranked size, they would have to continuously provide sperm to MPO.

It wasn’t an exaggeration to say the test was that important. Just as my heartbeat was beginning to settle, a beautiful woman entered the room.

“Hasegawa-san, thank you for coming today. I am Sara Amano, a physician affiliated with the Male Protection Organization. I believe you are already aware of today’s examination, but we will be conducting two tests: penis size and sperm quality. Based on the results of these tests, we will give you a badge displaying your assigned ranks, and you will be required to wear that badge in your daily life from now on. Wearing the badge is mandatory, so please understand. Now then, do you have any questions regarding the examination?”

Rather than cute, she gave off the impression of a cool beauty. She had short black hair, and even while seated, it was clear she had an excellent figure.

“Yes. I’d like to know more about the ranks.”

“Certainly. Regarding the ranks: based on penis size and sperm quality, men are assigned ranks from A to E. You may have seen men wearing badges such as ‘C.C’ around town; the first letter represents size, and the second letter represents sperm quality.”

“I’d like to know how the A-to-E ranks are divided.”

“Of course. I’ll explain briefly. For size:

Rank E is under 1 cm.

Rank D is 1 cm or more but under 4 cm.

Rank C is 4 cm or more but under 5 cm.

Rank B is 5 cm or more but under 8 cm.

Rank A is 8 cm or more.

For sperm quality:

Rank E is for those who are unable to ejaculate.

Rank D is for those who can ejaculate but lack the ability to have children.

Rank C is for those who can have children only through artificial insemination.

Rank B is for those who can have children through natural fertilization…That is, through sexual intercourse.

Rank A is for those with exceptionally superior sperm quality.

For reference, including overseas cases, there are currently eight men with Rank A in size and five men with Rank A in sperm quality. There are presently no men who hold Rank A in both categories. Do you have any other questions?”

Penis size wasn’t a problem. But sperm quality…I didn’t have the slightest clue about my sperm quality. 

“Will the examination be conducted alone?”

“Yes. The size examination is performed by a male physician or a specialized nurse who will measure it. As for sperm quality, you will generally perform it alone, but for those who do not know how to masturbate, a male physician or a specialized nurse will assist.”

“Thank you very much. Is it possible for us to choose who will handle the size measurement or assist with ejaculation?”

“Yes. That is possible. Please wait a moment;.I will show you a list of male physicians and female nurses who are currently available to assist—”

“Then I’d like to request Amano-sensei to assist me.”
