圣书云∶不孝有三，无后为大。盖为人子者，以宗祧为大事。大凡年轻之人，精力强壮，原不难于生子。
独恐其不安静，常多随受随落。至于男女体薄，而艰于子嗣者，延至四十之外，尚未得子，宁不心慌？其五六

而至自误无后耶。
其法先宜积德存阴 ，再自量男人本体如何。大凡难得子者，病有四件。其一气不足。临事必不能远射，
不射则精不入子宫，精不入子宫，孕从何来？且气旺则能生精，气虚则精必少。其二精薄。血虚则精必薄，

知种法。今总发于后，请细玩之，定当生多子。
圣人说：“不孝的行为有很多，其中没有后代是最大的。”作为子女，应当把延续宗族祭祀视为头等大事。一般来说，年轻人精力充沛、身体强壮，原本不难生育子女。
只是担心他们行为不稳重，常常是受孕后随即流产。至于那些体质瘦弱、难以生育的男女，如果拖延到四十岁以后还没有孩子，难道不让人心慌吗？如果是五六十岁的人，那更不用说了。如果想要孩子，请听我讲的方法，按照法则行事，生男生女的控制权其实掌握在自己手中，而且颇有灵验，怎么能把它当作戏言，以至于耽误了传宗接代的大事呢？
这个方法首先是积累阴德，然后要自我衡量男性的身体状况。大凡难以生育的情况，主要有四种病症。第一种是气不足。行房事时必然无法深入持久，如果不深入则精液不能进入子宫，精液不进子宫，怀孕从何而来？况且气旺才能生精，气虚则精液必然稀少。第二种是精液稀薄。血虚则精液必然稀薄，稀薄而不能凝结，怎么能形成胚胎？第三种是不留恋情场（指早泄）。假使遇到房事，还没进入阴道，精液就已经射出；或者虽然进入了，但没有交战几次就射出了。此时子宫尚未打开门户迎接，女方兴致刚起，男方兴致已尽，拿什么来结胎呢？第四种是精液寒冷。精液既然寒冷，投入体内必然不能凝结。因为阴阳交合，必须阳精热、阴户暖，两人的相火都旺盛，性志合而为一，一交一受，自然能成胎。就像春天温暖则万物发生，冬天寒冷则万物凋零，这是天地阴阳自然的道理。人有前四种病症，所以难以生育。然而这四种病症，我只用一个方剂进行加减变化，自能发挥其妙用，不像其他书籍罗列多方以求繁衍。长期服用我的药，病自然去除，孩子必定能得到。又如女性只要月经周期准确，没有不怀孕的，只恐怕体质瘦弱、血液不旺盛，这时可以娶年轻女子为妾，以形成老阳配少阴的景象。或者通过服药祛除疾病，病去经调，即使不吉利，我也只用一个方剂加减变化来发挥其妙用。天下娶妻却不生子的，都是男人身体不足，不是女人的罪过。男女都没有病了，为什么不立即生子，这是因为不知道播种的方法。现在总括在后面，请仔细研读，定能生出多个孩子。
The sage said: "Among the three unfilial acts, having no descendants is the greatest." As a child, one should regard the continuation of the ancestral lineage as a major affair. Generally speaking, young people with robust vitality and strong constitutions are not difficult to conceive children.
However, there is a fear that they may lack self-restraint, often resulting in conception followed by immediate miscarriage. For men and women with frail constitutions who struggle with infertility, if they reach beyond forty years of age without offspring, would it not cause anxiety? For those aged fifty or sixty, this need not be mentioned. If one desires offspring, listen to my words, act according to the method, for the power to determine the gender lies in one's own hands, and it is quite effective. How can one treat this as idle talk and thereby deprive oneself of descendants?
The method first involves accumulating virtue and preserving Yin, then assessing the male constitution. Generally, there are four pathological conditions leading to infertility. The first is Qi deficiency. During intercourse, one cannot maintain penetration for long; if penetration is insufficient, semen does not enter the uterus. If semen does not enter the uterus, from where can pregnancy arise? Moreover, abundant Qi generates essence, while deficient Qi leads to scanty essence. The second condition is thin semen. Blood deficiency results in thin semen; if it is thin and fails to coagulate, how can pregnancy form? The third condition is premature ejaculation (lack of retention). Suppose during intercourse, before entering the vagina, the semen is already ejaculated; or after entering, ejaculation occurs before several thrusts. The uterus has not yet opened to receive, the female arousal is just beginning, but the male excitement has ended. With what substance will the fetus be conceived? The fourth condition is cold semen. Since the semen is cold, upon introduction it will certainly not coagulate. In the union of Yin and Yang, the Yang essence must be hot, and the Yin cavity warm. When the ministerial fire of both individuals is vigorous, and their sexual intent unites in one place, through coupling and reception, the fetus naturally forms. Just as spring warmth causes all things to flourish, and winter cold causes all things to wither, this is the natural law of Heaven and Earth's Yin and Yang. Humans suffer from these four conditions, hence the difficulty in producing offspring. However, for these four conditions, I use only one formula with modifications to fully utilize its efficacy, unlike other books that list numerous methods for reproduction. Long-term consumption of my medicine will eliminate the disease and ensure the acquisition of children. Furthermore, women whose menstrual cycles are regular will conceive without fail. The only concern is if their constitution is frail and blood is not vigorous; in such cases, taking a younger wife creates the image of old Yang pairing with young Yin. Or, by taking medicine to cure the disease, once the disease is gone and menstruation is regulated, even if auspicious timing is lacking, I still use one modified formula to maximize its effect. Among those who marry but do not have children, it is always due to the man's insufficiency, not the woman's fault. If both man and woman are free from disease, why do they not conceive immediately? It is because they do not know the method of sowing seeds. Now, I summarize the following points; please study them carefully, and you will surely have many children.
