Tsunade said eagerly, "Shin, let me have some of your little tadpoles. I'll test them in the lab and see whether they're more energetic than an ordinary person's."

If someone with ulterior motives got their hands on Shin Uchiha's hundreds of millions of little tadpoles, and that person went a little mad, he could end up with tens of thousands of sons-enough to form an entire kekkei genkai army.
After all, the First had left only cells, which made fusion difficult, whereas with Shin Uchiha's little tadpoles, all it took was a suitable egg cell to grow a child who inherited his genes.
