和，气血平，则百病不生，而有子且寿矣。然既和之以阴阳，又宜按之以方法，诀曰∶

夫人至晚年无嗣，医皆责之于肾，肾以主精，精旺则孕成故也。殊不知肾主相火，
心主君火，一君一相，本于天成，君宁相服，精血乃生，盖心之所藏者神，神之所附

男女交媾，凝结成胎者，虽不离精血，犹为后天滓质之物，而一点先天之气，萌于

调补其气血。又有女子气多血少，寒热不调，月水违期，皆当诊脉而以活法治之，务
使夫妇之脉和平有力，交合有期，不妄用药，乃能生子也。其种子之道有匹，一曰择
地。地者，母血是也。二曰养种。种者，父精是也，三曰乘时。时者，精血交感之会是
也。四曰投虚。虚者，去旧生新之初是也。然少年生子多羸弱者，欲盛而精薄也。老年
主子多强壮者，欲少而精浓也。多欲者，子多不育，盖孕后不节，则盗泄母阴，以夺养胎之气。
严冬之后，必有阳春，是知天地之道，不收敛则不能发生，故冬寒得闭藏之令者，
则遇阳春，靡不发育，此自然之理也。令人
既昧收藏之理，纵欲竭精，以耗真气，及其无子，复云血冷，又谓精寒，燥热之剂过
投，而真阴益耗矣，安得而有子？故无子之因，不独在女，亦多由男，房劳过度，施泄
过多，精清如水，或冷如水，及思虑无穷皆难有子，盖心主神，有所思则神驰于外，致

夫五脏各有精，五脏平和，则脏藏之精华输归于肾，以资其用，盖肾为水脏，乃聚
会关司之所，故种子有百脉齐到之论，而《内经》有五脏盛乃能泻之语也。袁了凡曰∶
聚精之道，一曰寡欲，二曰节劳，三曰息怒，四日戒酒，五曰慎味。肾为精之府，凡
男女交接，必扰其肾，肾动则精血随之而流，外虽不泄，精已离宫，未能坚忍者，必
有真精数点，随阳痿而溢出，此其验也，故贵乎寡欲。精成于血，不独房室之交，损吾
之精，凡日用损血之事，皆当深戒。如目劳于视，则精以视耗；耳劳于听，则精以听
耗，心劳于思，则精以思耗，随事节之，则血得养而精与日俱积矣，故贵乎节劳。主闭
藏者，肾也。司疏泄者，肝也。二脏皆有相火，其系上属于心。心，君火也。怒则伤
肝，而相火动，动则疏泄用事，闭藏其职，虽不交合，亦暗流潜耗矣，故贵乎息怒。人
身之血，各归其舍则常凝，酒能动血，饮酒则面赤，手足俱红，是扰其血也，血气既衰
之人，数月无房事，精始浓而可用，一夜大醉，精随薄矣，故宜戒酒，《经》云∶精不
足，补以味。浓郁之味，不能生津，惟恬淡者，能补精耳。盖万物皆有真味，调和胜，
真味失矣。不论腥素，淡煮得法，自有一段冲和恬淡之气，益人肠胃。《洪范》论味而
曰∶稼穑作甘。世物惟五谷得味之正，若能淡食谷味，最能养精，如煮粥饮中有浓汁滚
作一团者，此米之精液所聚也。食之最能生精，故宜慎味。
天生各物，必有氤氲之时，万物化生，必有乐育之候，猫犬至微，将受娠也。其牝
者，必狂呼而奔跳，以氤氲乐育之气，触之不能自止，此天然之节候，生化之真机也。
凡妇人一月经行一度，必有一日氤氲之候，于一时辰间，气蒸而热，昏而闷，有欲交接
不可忍之状，此的候也。此时逆而取之则成丹，顺而施之则成胎矣。然男女交媾之时，
均有其精，何常有血？褚氏、东垣、丹溪，俱以精血混言，几见男女媾精，而妇人以血施也。
女子系胞于肾，及心胞络，皆阴脏也。虚则风寒乘袭子宫，则绝孕无子，非得温暖
药，则无以去风寒而资化育之妙，宜用辛温之剂，必加引经至下焦，走肾及心胞，散风
寒，暖子宫为要，更宜兼以补养气血之药。
若不兼补养，徒事辛温，则反增燥热之热，何以为化育之机耶！故血海虚寒而不孕者，
诚用暖药，但人之孕胎，阳精之施也，必阴血能摄之，精成其孕，血成其胞。若有真阴
不足，阴虚则火旺，阳胜则内热而血枯，是以不能摄受精血者，又不可纯用辛温之药
矣。《脉诀》曰∶血旺易胎，气旺难孕，故贵乎以脉消息，所以不能废诊也。至于父少
母老，生女必羸，母壮父衰，产男必弱，古人之成语。然有老者强，而少者弱，岂无变
异其间乎？但有生之初，虽阳子为正，育而充之，必阴为之主。
有妇人年三十四，梦与鬼交，及见神堂阴司，舟揖桥梁，如此一十五年，竟无妊
娠，此阳火盛于上，阴水盛于下。见鬼神者，阴之灵。神堂者，阴之所。舟揖桥梁，
水之用。两手寸脉皆沉而伏，知胸中有实痰也。三涌三泻三汗，不旬日而无梦，一月而有娠。
妇人不孕，亦有六淫七情之邪伤冲任，或宿疾淹留，传遗脏腑；或子宫虚冷；或气
旺血衰，或血中伏热∶或脾胃损，不能荣养冲任；或有积血积痰，凝滞胞络。更当审男
子形质何如？有肾虚精弱；有禀受不足，气虚血损；有嗜欲无度，阴精衰竭，各当求原
而治。又当审其男女尺脉，若有尺脉细或虚大无力，用八味丸。左尺洪大，按之无力，
用六味丸。两尺俱微细，或浮大，用十补丸。若徒用辛热燥血，不惟无益，反受其害矣。
世有妇人血气充实，饮食健旺，而生育则少，有血气不足，饮食减少，而生育偏多
者，何？盖卫府清肌，恒存辟谷，楚宫细腰，得之忍饥，月满则亏，月亏乃盈，由是
观之，弱者易育，实者难胎，此定理也。
褚氏曰∶男女之合，二情交畅，阴血先至，阳精后充，血开裹精，精入为骨，而男
形成。阳精先入，阴血后参，精开裹血，血入居本，而女形成。（此成胎以精血先后分男女也。）
《圣济经》曰∶天之德，地之气，阴阳至和，流薄一体，因气而左动则属阳，阳资
之则成男，因气而右动则属阴，阴资之则成女，《易》云∶干道成男，坤道成女，此男
女之分别也。（此成胎以左右阴阳之气动分男女也。）
《易》云∶干道成男，坤道成女，父精母血，因感交会，精之泄阳之施也。血能摄
[Blood Wind Itch]
Women suffering from Blood Wind Itch (Xue Feng Chuang) are caused by wind-heat stagnation and fire in the Liver and Spleen meridians, leading to blood dryness. External symptoms include nodules appearing on the body, alternating itching and pain, which become sores with oozing pus and fluid when scratched. Internal symptoms include irregular menstruation, dysuria, night fever with night sweats, aversion to cold and hatred of heat, fatigue, and poor appetite. Treatment should initially use Modified Xiaoyao San (Jia Wei Xiao Yao San) or a combination of Xiao Chai Hu Tang (Minor Bupleurum Decoction) and Si Wu Tang (Four Substances Decoction), adding more Sesame seeds (Humaizi). Subsequently, use Guipi Tang (Restore the Spleen Decoction) with Shu Dihuang (Prepared Rehmannia Root), removing Muxiang (Aucklandia Root).
[Dreams of Intercourse with Ghosts]
"Dreaming of intercourse with ghosts" occurs due to deficiency and decline of Qi and Blood, excessive thinking, consumption of Shen (Spirit), allowing external pathogens to invade when defenses are weak. The presentation includes laughing and crying intermittently, avoiding people, as if conflicting with others. The pulse is slow and deep, or intermittent like a crow pecking, or continuous without rhythm, fluctuating between large and small, short and long. This is entirely due to the Seven Emotions damaging Heart Blood, leaving the Shen unprotected. It is appropriate to use herbs that calm the Shen and stabilize the Will (An Shen Ding Zhi). When Zheng Qi (Upright Qi) recovers, the Shen naturally settles. Externally, bind the patient's two thumbs together tightly with thread. At the junction between the nail and skin on the outer side of the seam, known as the Guiku Acupoint (Ghost Cry Point), apply moxibustion for seven moxa cones. If it is indeed an evil influence, the patient will beg to stop the moxibustion, and the illness will depart. However, the Five Zang each store specific entities: the Heart stores Shen, the Liver stores Hun (Ethereal Soul), the Lungs store Po (Corporeal Soul), the Spleen stores Yi (Intellect), and the Kidneys store Jing (Essence) and Zhi (Will). If Heart Blood is deficient, Shen has no basis; if Liver Blood is deficient, Hun has no attachment; if Lung Qi is deficient, Po has no return; if the Spleen and Kidneys are deficient, Yi and Zhi detach from the body, causing dreams of ghosts at night. What is seen is merely one's own Hun and Po. Is there truly a ghost interacting? Xue Lizhai attributed this to damage from the Seven Emotions and insufficient Heart Blood failing to protect the Shen, which truly grasps the fundamental principle of the condition.
[Introduction to Procreation]
The great virtue of Heaven and Earth is "Life". The Qi of generation flows everywhere; why should it cease only for me? Human lineage connects to ancient times and extends endlessly. Is this not important? Ancestors' commands have lasted thousands of generations; if they end with me, how can filial sons not pray to Heaven and Earth and blame themselves? Mr. Liaofan said: "Love" is the root of life; restraining it cuts off the root. *Su Wen* states: "Those who follow the Dao can resist aging and preserve their form, living to hundreds of years and still having children." Thus, there are no sages without offspring. Who does not take kindness and love for the Dao as the root, and act upon it? Then auspicious signs will appear endlessly.
Women unable to conceive may have four causes: irregular menstruation, insufficient Blood, disease, or untimely intercourse. Regulate menstruation and tonify Blood, remove disease and restrain desires, ensure no disease and timely intercourse, and pregnancy will occur. However, two other conditions exist: Obese women with strong constitution who indulge in alcohol and food cannot conceive, called "abdominal fat overflowing, blocking the uterus"; treat with damp-drying and phlegm-resolving herbs like Banxia (Pinellia Rhizome), Chenpi (Tangerine Peel), Cangzhu (Atractylodes Rhizome), Chuanxiong (Sichuan Lovage Rhizome), Xiangfu (Cyperus Rhizome), or Daotan Tang (Phlegm-Dredging Decoction). Thin, irritable women with irregular menstruation cannot conceive, called "dry uterus lacking Blood", unable to capture sperm; treat with cooling Blood and descending Fire, such as Si Wu Tang plus Huangqin (Scutellaria Root) and Xiangfu, or Liuwei Dihuang Wan (Six-Ingredient Pill with Rehmannia).
Men and women must be of appropriate age. Although men's Jing flows at 16, marriage should be at 30; although women's Tian Gui arrives at 14, marriage should be at 20. Only when Yin and Yang are complete and solid should intercourse occur to conceive, nurture, and produce robust, long-lived children. Young girls whose Tian Gui has just arrived but engage in sexual activity suffer premature leakage of Yin Qi, injury before maturity, and movement before solidity, leading to infertility, miscarriage, or weak offspring.
Heaven and Earth are large forms; Yin and Yang are large Qi. Form and Qi support each other. Male and female essence interaction generates all things. Regarding the numbers seven and eight: seven is Shaoyang (Lesser Yang), eight is Shaoyin (Lesser Yin). They interact and flow. Women's Tian Gui arrives at 2x7 (14); men's Jing flows at 2x8 (16). This is the beginning of Yin-Yang union. The *I Ching* says: "Heaven and Earth interact, all things become pure; male and female essence unite, all things are born." Heaven and Earth's way requires Yin-Yang harmony for generation; husband and wife's way requires Yin-Yang harmony for birth. If father's Jing and mother's Blood are insufficient, pregnancy is impossible. Therefore, seeking conception requires checking if the woman's menstruation is regulated. "Jing" means constancy: arriving on time, stopping on time. Irregularities include early/late arrival, twice a month, every other month, amenorrhea, frequent bleeding, pain before/after flow, black/purple/light colors, leukorrhea, etc. These indicate Blood-Qi disharmony and require symptom-based regulation.
Men's diseases must also be known: Kidney deficiency with seminal emission, cold/clear semen, erectile dysfunction (strong externally due to Liver Fire, non-ejaculation due to weak True Yang), night sweats/dream emission, turbid/dysuric urine, back fatigue, Yin deficiency from lust, labor heat, deficiency cold, Yang deficiency with weak Qi, or Yin lack with depleted Jing. These require symptom-based tonification. If the woman's channels are regulated and the man's Jing is sufficient, Yin-Yang harmonizes, Blood-Qi balances, diseases do not arise, and conception leads to longevity.
After harmonizing Yin-Yang, follow specific methods: "In twenty days, two and a half days are key, calculate days 28-29. Red discharge indicates the good period; after Jin-Shui passes, confusion ensues. Wasted effort then; search trees for remaining red. If you understand flowers bear fruit, why worry about osmanthus not clustering?" This refers to the time after menstruation ends, when Jin-Shui (Water/Metal phase) begins, the uterus is open and empty, ready to receive essence. This is the optimal time for conception. After this, the uterus closes.
Timing affects gender: Intercourse 1-3 days after menstruation, new Blood is not full, Jing overcomes Blood, resulting in a male (Qian Dao creates male). Days 4-6, Blood grows, Blood overcomes Jing, resulting in a female (Kun Dao creates female). If Yin Blood arrives first and Yang Jing follows, Blood wraps Jing, Jing enters as bone, Yang inside Yin outside, forming Kan Trigram (Yang dominant, male). If Yang Jing enters first and Yin Blood follows, Jing wraps Blood, Blood enters as root, Yin inside Yang outside, forming Li Trigram (Yin dominant, female). Heaven and Earth interact for prosperity; Yin-Yang harmony for birth. Those biased toward Yang Qi become male; those biased toward Yin Qi become female. To broaden lineage, seek this method. Deviation leads to miscarriage, difficult birth, or sick children.
Men with thick build and deep/small pulse, young but unstable Yang, have insufficient Yuan Qi; use Renshen Gao (Ginseng Paste) or add Baizhu (Atractylodes Macrocephala Rhizome). Middle-aged men with weak Yang, increasing obesity, many concubines but no children, have abundant stomach fat but internal Qi weakness; use Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) with Lujiao (Deer Antler Glue), Gouqi (Goji Berry), Zhifuzi (Prepared Aconite Root), Suoyang (Cynomorium Herb), and Congrong (Cistanche Stem). Supplement Minister Fire, reduce rich/greasy foods to clear turbidity and secure Jing. Spleen-Stomach disharmony with poor appetite/fatigue worsening after sex indicates weak Middle Qi; use Buzhong Yiqi Tang. Black/thin individuals with wiry/rapid pulse, heat, dry intestines, unable to conceive, have insufficient Yin Water; even if pregnant, fetus may die; use Liuwei Dihuang Wan plus Zhimu (Anemarrhena Rhizome), Huangbai (Phellodendron Bark), Danggui (Angelica Sinensis Root), and Gouqi, ensuring Yin-Yang balance, not necessarily using hot herbs.
Older adults without children are often blamed on Kidneys. Kidney governs Jing; abundant Jing leads to pregnancy. But Kidney governs Minister Fire, Heart governs Lord Fire. One Lord, one Minister, formed by Heaven. If Lord Fire is calm, Minister Fire obeys, Jing-Blood generates. Heart stores Shen, Shen attaches to Blood, Blood fears Fire. Heart desire moves Fire, boiling Blood, depleting Shen, preventing descent to Kidney. Kidney Water becomes cold, Jing leaks. Heart Fire moves, Minister Fire follows, disturbing the Heavenly Lord (Heart). Heart and Kidney depend on each other. The wealthy often lack heirs because wealth breeds lust (damaging Jing) and status breeds mental labor (damaging Shen). Jing leaks due to Fire pressure; Heart Fire rises due to lack of Water control. After age 30, Jing-Qi declines. Sensory interactions consume Shen-Qi. Unrestrained desires damage Jing/Shen. Preserving Harmony and expanding lineage requires moderation.
Conception involves Jing-Blood but relies on a spark of Pre-Heaven Qi arising from desire. High doctors treat infertility by focusing on Male Jing and Female Blood, supplementing Kidney for men, regulating menstruation for women, considering Qi tonification/movement, examining pulses, and treating based on excess/deficiency. Pulses should not be too large/rapid (Heat), too small/slow (Cold), too forceful/excess (Deficient Righteous Qi with pathogenic Fire), or too weak/deficient (Blood-Qi deficiency). Women with excess Qi/deficient Blood, temperature imbalance, and irregular menses require pulse diagnosis and flexible treatment. Couples' pulses should be peaceful and strong, intercourse timed, medication used wisely.
Seed-conceiving principles: 1. Select Land (Mother's Blood). 2. Nourish Seed (Father's Jing). 3. Ride Time (Moment of Essence-Blood interaction). 4. Enter Emptiness (Initial stage of discarding old/generating new). Youthful fathers have weak children due to high desire/thin Jing; elderly fathers have strong children due to low desire/thick Jing. Excessive desire leads to infertile offspring because post-conception unrestraint drains Mother's Yin, stealing nourishing Qi. Winter precedes Spring; Heaven's way requires storage for generation. Winter closure allows Spring development. Ignoring storage, exhausting Jing through lust, then blaming Cold Blood/Cold Jing and using hot/dry herbs consumes True Yin, preventing conception. Infertility stems from both sexes: excessive sexual activity, thin/cold semen, endless worrying. Heart governs Shen; thought scatters Shen, injuring Lord Fire. Kidney governs Wisdom; labor confuses Wisdom, injuring Kidney. Upper/Lower non-interaction, Water/Fire non-communion prevents fertility.
Five Zang each store Jing; peace among Zang sends essence to Kidney. Kidney is Water Organ, gathering point. "Hundred pulses arrive together" theory exists; *Neijing* states "Five Zang abundant then able to discharge." Yuan Liaofan: Gather Jing by: 1. Few desires, 2. Moderate labor, 3. Rest anger, 4. Quit alcohol, 5. Careful diet. Kidney is Jing mansion; intercourse disturbs Kidney, moving Jing-Blood. Even if not ejaculated, Jing leaves palace; inability to maintain erection shows true Jing leaking. Hence, few desires. Jing forms from Blood; daily activities damaging Blood (eye strain, ear strain, mental labor) consume Jing. Moderation preserves Blood and accumulates Jing. Hence, moderate labor. Kidney stores; Liver disperses. Both have Minister Fire, connected to Heart (Lord Fire). Anger injures Liver, moving Minister Fire, causing dispersion/storage failure, leaking Jing even without intercourse. Hence, rest anger. Alcohol moves Blood; face/hands redden. In weakened persons, months of abstinence thicken Jing; one night of drunkenness thins it. Hence, quit alcohol. *Classic*: "Insufficient Jing, tonify with taste." Rich tastes don't generate fluids; bland tastes tonify Jing. All things have true taste; strong flavors lose it. Light cooking preserves harmonious Qi benefiting Stomach-Intestines. *Hongfan*: "Grains make sweet." Grains have correct taste; bland grain diet nourishes Jing best. Rice porridge concentrate is grain essence; eating it generates Jing. Hence, careful diet.
All things have a "Yinyun" (misty/vital) time for generation. Cats/dogs show this before pregnancy. Women have one Yinyun day per menstrual cycle, within one shichen (2 hours): steaming heat, dizziness, unbearable urge for intercourse. This is the precise timing. Reversing it makes Elixir; following it makes Fetus. Men/Women both have Jing; where is Blood? Chu Shi, Dongyuan, Danxi confused Jing/Blood. Women's uterus connects to Kidney and Pericardium (Yin organs). Deficiency allows Wind-Cold to attack uterus, stopping pregnancy. Warm herbs are needed to dispel Wind-Cold and aid transformation, using acrid-warm agents guiding to Lower Jiao, Kidney, Pericardium, warming uterus, combined with Blood-Qi tonics. Without tonification, acrid-warm herbs increase dryness-heat, hindering transformation. For Blood Sea deficiency-cold, warm herbs are used. But pregnancy requires Yang Jing applied and Yin Blood capturing it. If True Yin is insufficient, Yin deficiency leads to Fire hyperactivity, Yang excess leads to internal heat and Blood depletion, preventing capture. Pure acrid-warm herbs are unsuitable. *Maijue*: "Abundant Blood easy to conceive; Abundant Qi hard to conceive." Pulse diagnosis is essential. Father young/Mother old -> weak daughter; Mother strong/Father weak -> weak son. Ancient sayings, but variations exist. Initially Yang seed is correct, but nurturing requires Yin dominance.
Case: 34-year-old woman, dreamed of ghost intercourse, saw spirit halls/underworld/boats/bridges for 15 years, no pregnancy. Yang Fire excess above, Yin Water excess below.
