胡氏曰∶男女交媾，其所以凝结而成胎者，虽不离乎精血，犹为后天滓质之物，而一点
先天真一之灵气，萌于情欲之感者，妙合于其间。朱子所谓禀于有生之初，《悟真篇》所谓
生身受气初者是也。医之上工，因人无子，语男则主于精，语女则主于血，着论立方，男以
补肾为要，女以调经为先，而又参之以补气行气之说，察其脉络，究其亏盈，审而治之，夫
然后一举可孕，天下之男无不父，女无不母矣。
陈楚良曰∶人身气血，各有虚实寒热之异，惟察脉可知（以尺寸浮沉分气血），舍脉而独言药者妄也。脉有十
二经，应十二时，一日一周，与天同运，循环无端。其至也，既不宜太过而数，数则热矣；
又不宜不及而迟，迟则寒矣。不宜太有力而实，非正气能自实也，正气虚而火邪来乘以实之
也，治法先当散郁，以伐其邪，邪去而后正可补也。不宜太无力而虚，虚乃正气正血虚也，
治法惟当补其气血耳（又须分出气虚、血虚，不可并补）。亦有男妇上热下寒（寒热有上下，
治法分早晏），表实里虚，而未得子者，法当临睡时，服凉膈之
药，以清其上；每晨食未入口时，服补药以温其下；暂进升散之药，以达其表，及服浓味之
药，以实其里。又有女人气多血少，寒热不调，月水违期，或后或先，白带频下而无子者，
皆当诊脉而以活法治之，务欲使其夫妇之脉，皆和平有力，不热不寒，交合有期，不妄用精
，必能生子，子不殇夭。故欲得子者，必须对脉立方，因病用药。
胡氏说：男女交媾，其中凝结形成胎元的物质，虽然离不开精和血，但这仍属于后天形成的渣滓性质的物质；而一点先天的真一灵气，萌发于情欲触动之时，奇妙地融合在精血之间。这就是朱熹所说的“禀受于生命初始之时”，《悟真篇》中所说的“生身受气之初”的情形。医术高明的医生，针对夫妻无子的情况，论述男性时以精为主，论述女性时以血为主，撰写论文并制定方剂，治疗男性以补肾为关键，治疗女性以调理月经为先导，同时参考补气、行气的理论，观察其经络脉络，探究其盈亏状况，审慎地进行治疗，这样之后才能一次受孕成功，天下的男子没有不能做父亲的，女子没有不能做母亲的。
陈楚良说：人身的气血，各有虚实寒热的差异，只有通过诊察脉象才能知晓（通过寸口尺部的浮沉来区分气血），舍弃脉象而单独谈论用药是荒谬的。脉象对应十二经脉，顺应十二时辰，一天循环一周，与天体运行同步，循环往复没有尽头。脉象的到来，既不应该太过急促而频数，频数则代表热证；也不应该不及而迟缓，迟缓则代表寒证。脉象不宜过于有力而呈现实象，这并不是正气自然充实的表现，而是正气虚弱，火邪乘虚侵袭导致脉象显得充实，治疗方法应当先疏散郁结，以祛除邪气，邪气去除后正气才可以补益。脉象不宜过于无力而呈现虚象，虚象乃是正气和正血亏虚所致，治疗方法只应当补益气血（又必须分辨是气虚还是血虚，不可一并补益）。也有男女患者上热下寒（寒热症状有上下之分，治疗方法需分早晚进行）、表实里虚，而未能生育的情况，治法应当在临睡时，服用凉膈散之类的药物，以清泄上部之热；每天早晨进食前，服用补药以温煦下部；暂时进用升散性质的药物，以通达肌表，以及服用滋味浓厚的药物，以充实内部。又有女性气多血少，寒热不调，月经周期紊乱，或提前或推后，白带频繁流出而不能生育的情况，都应当诊察脉象，运用灵活的方法治疗，务必使夫妇双方的脉象都平和有力，不热不寒，交合有定时，不妄泄精气，必定能生育子女，且子女不会夭折。所以想要生育子女的，必须根据脉象制定方剂，因病使用药物。
Hu stated: In the coitus of men and women, although the substance that condenses to form the fetus relies on essence (Jing) and blood, these still belong to postnatal turbid matter. However, a spark of the primordial true one spiritual energy (Xiantian Zhenyi Lingqi), which sprouts from the stimulation of desire, miraculously merges within this process. This is what Zhu Xi referred to as "endowed at the beginning of life," and what the *Wuzhen Pian* (Awakening to Reality) describes as the "initial stage of receiving life and qi."
Superior physicians, addressing infertility in couples, emphasize essence in men and blood in women when discussing pathology. They write treatises and prescribe formulas, prioritizing tonifying the Kidney for men and regulating menstruation for women. They also incorporate theories of tonifying and moving Qi, observe the meridians and collaterals, investigate their deficiency or fullness, and treat them prudently. Only then can conception occur successfully in one attempt, ensuring that no man fails to become a father and no woman fails to become a mother.
Chen Chuliang stated: The Qi and Blood in the human body vary in deficiency, excess, cold, and heat; only through pulse diagnosis can these be known (distinguishing Qi and Blood by the floating and sunken qualities at the Cun and Chi positions). To discard pulse diagnosis and speak solely of medication is absurd. The pulses correspond to the twelve meridians and the twelve double-hours, completing one cycle daily, moving in harmony with the heavens, circulating endlessly.
The arrival of the pulse should not be too rapid and frequent; frequency indicates Heat. It should not be too slow and delayed; delay indicates Cold. It should not be overly forceful and solid; such solidity does not indicate natural sufficiency of Righteous Qi (Zhengqi), but rather that Righteous Qi is deficient while Fire Pathogens have invaded, creating a false sense of fullness. The treatment method should first disperse stagnation to eliminate the pathogen; only after the pathogen is gone can Righteous Qi be tonified.
The pulse should not be too weak and empty; emptiness signifies a deficiency of Righteous Qi and proper Blood. The treatment method should solely focus on tonifying Qi and Blood (one must distinguish between Qi deficiency and Blood deficiency; they should not be tonified indiscriminately together).
There are also cases where men and women suffer from Upper Heat and Lower Cold (where treatment timing differs for morning and evening), Exterior Excess and Interior Deficiency, yet fail to conceive. In such cases, the method is to take cooling medications for the Middle Jiao (such as Liangge San) before sleep to clear upper heat; take tonifying medications to warm the lower part every morning before eating; temporarily use ascending and dispersing medications to reach the exterior; and consume rich-flavored medications to fortify the interior.
Furthermore, in women with excessive Qi and deficient Blood, irregular cold and heat, menstrual cycles that are either early or late, and frequent leukorrhea leading to infertility, pulse diagnosis must be performed, and flexible treatments applied. The goal is to ensure both husband and wife have pulses that are peaceful and forceful, neither hot nor cold, with regulated intercourse and no reckless emission of essence. This will certainly result in childbirth, and the children will not die young. Therefore, those wishing to conceive must formulate prescriptions based on the pulse and medicate according to the disease.
