Naruto

The young blonde stood in front of Tsunade nearly naked save for a single towel.

"Are you sure I have to do this?"

"Steps have to be taken to warn our the villages. If you want to be Hokage you need to take point on alerting our people on this crisis. You know that we've lost innumerable people during this war our population needs to rebuild."

The young blonde shook his head still not convinced. Naruto was about to walk away when he felt a strong hand on his shoulder. He turned back towards Tsunade despondently.

"The women need to know the genetic pitfalls of men with certain genes. Sperm count could decrease with each generation leading to eventual sterility. Impotence likelihood increases with each decade after age twenty in these men."

Tsunade looked into Naruto's eyes severely making him flinch. He turned away muttering and cursing before nodding and getting on the table. Shizune then came in and strapped Naruto tightly before she gave her condolences for what was about to happen. The curtain then rose revealing numerous Kunoichi both medically trained and untrained.

"Greetings Kunoichi of the hidden villages. I'm Tsunade Senju I am the foremost expert in Konaha on genetics. I've called all of you hear to alert you of a recent discovery I made. There is a threat to the population growth of our hidden villages."

Several Kunoichi began to mutter amongst themselves.

Sakura stood up with a worried look. "Sensei just what is this discovery?"

"A number of males within several villages have been shown to carry deleterious genes. These genes lower the total sperm count of the our village's gene-stock. Due to the losses of our war these men pose a considerable obstacle to rebuilding prewar numbers. So they must not be allowed in the genepool."

Karin raised her hand and Tsunade sighed before motioning her to speak.

"Lady Senju. Is there any physical characteristics that we can use to identify unsuitable males?"

"Yes there is. I've recently found a direct correlation between penis size and the deleterious genes."

A catlike grin grew on Karin's face as she realized why her cousin was on the table. "I see Wow!! This so brave of you Naruto!!" She exclaimed with an insincere bow.

"Thanks." Naruto muttered bitterly.

Tsunasde continued with her speech uncaring of her patient's current turmoil. "Today we will be examing Naruto Uzumaki's reproductive organs and his sperm's vitality in detail using Konoha's advanced monitors and scanners. Once we are done with the examination you can ask all questions you want."

She then reached for the blanket exposing Naruto's minuscule member to the women.
