Halakhah for Niddah 86:55

have conveyed any uncleanness?<span class="x" onmousemove="('comment',' Obviously not; which shows that it is only on account of its importance that the force of conveying uncleanness (as a piece of the prescribed size) was imparted to it. Any other part of the body, however, is subject to the prescribed minimum. ');"><sup>43</sup></span>
Sefer HaChinukh
From the laws of the commandment is that which they, may their memory be blessed, said (Niddah 43b) that the measure for one who touches [it] is like [the size of] a lentil, and for one who [experiences] the emission is with the smallest amount. And it is one, whether he [experiences] the emission accidentally or volitionally, he is impure. And the seed of a young child does not render impure. And red seed does not render impure, but rather [only] white. And any seed that a man does not feel - not at the beginning and not at the end - is not impure. And one who has [improper] thoughts at night, and saw in a dream that he had sexual relations and got up and found his flesh [to be] warm, is impure - even though he did not [knowingly experience] semen. And the rest of its details are elucidated in Tractate Zavim (see Mishneh Torah, Laws of Offerings for Those with Incomplete Atonement 1).
