种子之方，本无定轨，因人而药，各有所宜。故凡寒者宜温，热者宜凉，滑者宜涩，
虚者宜补，去其所偏，则阴阳和而生化着矣。今人不知此理，而但知传方，岂宜于彼者亦
宜于此耶？且或一人偶中，而不论宜否，而遍传其神，竞相制服，又岂知张三之帽，非
李四所可戴也？
凡饮食之类，则人之脏气各有所宜，似不必过为拘执，惟酒多者为不宜。盖胎种先
天之气，极宜清楚，极宜充实，而酒性淫热，非惟乱性，亦且乱精，精为酒乱，则湿热其
半，真精其半耳。精不充实，则胎元不固，精多湿热，则他日痘疹惊风脾败之类，率已受
造于此矣，故凡欲择期布种者，必宜先有所慎，与其多饮不如少饮，与其少饮犹不如不
饮，此亦胎元之一大机也。欲为子嗣之计者，其毋以此为后着。
疾病之关于胎孕者，男子则在精，女子则在血，无非不足而然。凡男子之不足，则
有精滑精清精冷者，及临事不坚，或流而不射者，或梦遗频数，或便浊淋涩者，或好色
以致阴虚，阴虚则腰肾痛惫，或好男风以致阳极，阳极则亢而亡阴，或过于强固，强固
则胜败不治，或素患阴疝，阴疝则肝肾乖离，此外则或以阳衰，阳衰则多寒，或以阴虚，阴
虚则多热。若此者，是皆男子之病，不得尽诿之妇人也。倘知其由而宜治则治之，宜反
则反之，必先其在我而后及妇人，则事无不济矣。
种子（助孕）的方法，本来没有固定的规律，要根据个人的体质用药，每个人适合的方法各不相同。所以凡是体质偏寒的适宜用温性药物，体质偏热的适宜用凉性药物，滑泄的适宜用固涩药，虚弱的适宜用补益药，去除体质的偏颇，那么阴阳调和，生命化生的功能就能显现了。现在的人不懂这个道理，只知道传授方子，难道适合别人的也一定适合自己吗？况且或许有人偶然成功，就不论是否适宜，到处宣扬其神效，争相服用，这又怎么知道张三的帽子，李四戴不上呢？
至于饮食方面，人的脏腑之气各有所宜，似乎不必过分拘泥执着，只有饮酒过多是不适宜的。因为胎元（胚胎形成的先天之气）极其需要清澈纯净，极其需要充实，而酒的性质淫荡燥热，不仅扰乱心神，也会扰乱精液，精液被酒所乱，则一半是湿热，一半是真精亏损。精液不充实，则胎元不稳固；精液中多湿热，那么日后孩子出现痘疹、惊风、脾败等病，大多是在受孕时就已经造成了。所以凡是想要选择日期播种受孕的人，一定要先有所谨慎，与其多喝不如少喝，与其少喝还不如不喝，这也是关于胎元的一大关键。想要为子嗣做打算的人，不要把这一点当作次要的事情。
疾病中关系到胎孕的，男子在于精，女子在于血，无非都是不足导致的。大凡男子的不足，就有精液滑脱、精液清稀、精液寒冷等情况，以及临房时不坚挺，或者只流出不射精的情况，或者梦遗频繁，或者小便浑浊淋漓涩痛的情况，或者因为好色导致阴虚，阴虚则腰肾疼痛疲惫，或者因为男风（男性同性恋行为）导致阳极，阳极则亢奋而亡阴，或者过于强行固守（指忍精不射），强固则胜败无法治愈，或者素来患有阴疝（阴囊肿胀疼痛等病），阴疝则肝肾乖离，此外还有因为阳衰，阳衰则多寒，或者因为阴虚，阴虚则多热。像这些情况，都是男子的病，不能全部推卸给妇人。如果知道病因且适宜治疗就治疗它，适宜反向调理就反向调理，必须先调理自身然后再顾及妇人，那么事情就没有办不成的了。
The methods for enhancing fertility (Zizhong) have no fixed rules; medication should be tailored to the individual, as each person has their own suitability. Therefore, those with Cold patterns are suitable for warming therapies, those with Heat patterns for cooling therapies, those with Slippage (incontinence or leakage) for astringent therapies, and those with Deficiency for tonifying therapies. By removing these deviations, Yin and Yang will harmonize, and the transformative functions of life will manifest. Nowadays, people do not understand this principle but merely pass on prescriptions. How can what is suitable for one be suitable for another? Moreover, if someone happens to succeed by chance, they may indiscriminately spread its miraculous reputation without considering suitability, leading others to compete in taking it. Do they not know that a hat fitting Zhang San may not fit Li Si?
Regarding diet and beverages, different individuals' Zang-Fu Qi have different preferences, so one need not be overly rigid. However, excessive alcohol consumption is unsuitable. The congenital Qi of the fetal origin (Taiyuan) requires utmost clarity and fullness. Alcohol possesses a licentious and hot nature; it not only disturbs the Shen (Spirit) but also disrupts the Jing (Essence). When Jing is disturbed by alcohol, half becomes damp-heat and half suffers from depletion of true Essence. If Essence is not substantial, the fetal origin will not be secure. If Essence contains much damp-heat, conditions such as smallpox/rash (Douzhen), convulsions/wind (Jingfeng), and Spleen failure (Pibai) in later years are likely already determined at conception. Thus, those wishing to select an auspicious time for conception must exercise caution. It is better to drink less than more, and better to drink less than not to drink at all. This is a major mechanism concerning the fetal origin. Those planning for offspring should not treat this as a secondary matter.
Diseases affecting pregnancy differ by gender: in men, it concerns Jing (Essence); in women, it concerns Blood (Xue). These are invariably due to insufficiency. In men, insufficiency may manifest as seminal emission (Jinghua), clear semen, cold semen, lack of firmness during intercourse, dribbling without ejaculation, frequent nocturnal emissions, turbid urine with dysuria, or Yin Deficiency caused by excessive sexual activity, leading to soreness and fatigue of the lower back and kidneys. Alternatively, practices such as homosexuality (Nanfeng) may lead to Extreme Yang, resulting in hyperactivity and loss of Yin. Forcing retention of semen may lead to unresolved conflict between victory and defeat. Pre-existing Yin Hernia (Yinshan, referring to scrotal disorders) causes disconnection between Liver and Kidney. Additionally, Yang Decline leads to excess Cold, while Yin Deficiency leads to excess Heat. All these are male pathologies and cannot be entirely blamed on the woman. If the cause is identified and treatment is indicated, it should be administered; if reversal therapy is needed, it should be applied. One must first regulate oneself before attending to the wife, then success is assured.
