Reference for Sanhedrin 137:7

לא לעולם דאיעבר בתר דאייתי שתי שערות ואוליד בתר דאקיף זקן ודקא קשיא דרבי כרוספדאי כי אתא רב דימי אמר אמרי במערבא בן ולא הראוי לקרותו אב

<font>a man can inflame [his genital] and emit semen</font>, but not a minor.<span class="x" onmousemove="('comment',' Hif'il, [H] (come presumptuously), is here derived from [H], to seethe, Hif'il, hezid, to cook, boil, the technical terms for the excitation producing semen. Rashi states that this interpretation is placed upon the word, for if mere wanton wickedness were referred to, Scripture should have written Yarshia' [H] from [H], a wicked man. Thus, by this exegesis, a minor is excluded from the scope of the law. ');">⁶</span>
