In the thread on Queen Succession Rules, the topic about "the point at which the mantle of Lady would be destroyed came up. Mab defines it as the Lady "to become a mother." Her statement is as follows.
"Three Queens of Summer; three Queens of Winter," she said, that alien gaze returning to me. "Maiden, Mother, and Crone. You are the Maiden, Lady Molly. And for you to be otherwise, to become a mother, would be destroy the mantle of power you wear." The mantle protected itself--as it must.
"What?"
She tilted her head and stared at me. "It is all within the law. I suggest you spend a few hours each day meditating on it in the future. In time you will gain and adequate understanding of your limits."
We have seen that there is a self defense mechanism within the Lady mantle that prevents sex, but if push came to shove could a pregnant Lady exist. We know that only 'to become a mother' destroys it. Anyway, that is a topic of another thread. Now shift back to Harry's sperm
I have wondered if Harry, wielding the Knight's power, is having his sperm changed such that his children from this point forward will have greater fae genetics. I wondered how such condition would affect a child sired by Harry with Murphy. And should such child, fetus at this point, accompany Murphy in time traveling into the distant past to become Mab.
To simplify the main topic of discussion, I assert that Harry's future children will have very high levels of fae genetics.
