男子以阳用事。从乎火而主动。动则诸阳生。女子以阴用事。从乎水而主静。静则众阴集。故
治男子。毋过温热以助其阳。治女子。无过寒凉以益其阴。古人黄柏知母之药。每用于男子。而干
姜艾叶之剂。慎施于妇人。男女阴阳自然之体。固有不得而同者。至于七情内伤。六淫外浸。发为
诸病。治热以寒。制寒以热。随证推移。安能执此。但男女嗣续稍迟。虽无疾病。当加调护。男子
阳动之体。惟虑合而易失。未获中其肯綮。女人阴静之质。多苦交而弗孕。不能遂其生成。由是培养
之术。若不可废。在男子则用思仙丹。收固真阴。以为持久之计。在女子则用启荣丸。鼓作微阳。以
为发育之基。窃观古今种子诸方。不偏于寒。即偏于热。务张其功以矜世。不析其理以示人。往往
服之反致求全之毁。故述二方。以为世之求嗣者助焉。
宜旺相吉日
春甲乙寅卯 夏丙丁巳午 秋庚辛申酉 冬壬癸亥子
忌弦望晦朔。大风大雨。虹霓雷电。云雾昏暝。日月薄蚀。三光之下。及春秋冬丙丁日。
本命乃劬劳之日。亦不可行也。上宜谨之慎之。
\r实阳能入虚阴之图\p04-a59a1.bmp\r
实阳能入虚阴。谓男子阳精充实。适值女人经后血海虚静。子宫正开。与之交合。是谓投虚。一
举而成胎矣。
经静一日交会者成男。二日者成女。三日成男。四日成女。五日成男。六日成女。取奇阳偶阴之义。
六日无用矣。大抵前三日。新血未盛。精胜其血。血开裹精。必成男胎。后三日。新血渐长。
血胜其精。精开裹血。多成女胎。交合得夜半后生气时。有子皆男而寿。
\r实阴不能受阳之图\p04-a59a2.bmp\r
实阴不能受阳。谓女人经尽六日之后。新血方盛。血海充满。若与交合。以实投实。多不成胎。
又有妇人素禀怯弱。虽经后旬日。血海未满。亦复成胎。然皆女子。亦血胜其精故也。
\r弱阴不能摄阳之图\p04-a59a3.bmp\r
弱阴不能摄阳。谓女人阴血衰弱。虽投真阳强盛之精。不能摄入子宫。是以交而不孕。孕而不育。
或因病后产后经后。将理失宜。劳动过节。亏损阴血所致。治宜调经养血。
\r微阳不能射阴之图\p04-a59a4.bmp\r
微阳不能射阴。谓男子阳精微薄。虽遇女人血海虚静之日。流而不射。多不成胎。盖因平时嗜欲
不节。施泄太多所致。法当补益精元。兼用工夫存养。无令妄动。候阳精充实。才授投虚之法。一举而成矣。
两尺脉洪大或数。小便常赤。未交易兴。既交易泄。或自遗梦遗。真精不固。治在补阴。
两尺脉微或迟。小便常清。阳事不举。勉力入房。未竟先痿。或所泄清冷微薄。治在补阳。
男子以阳气为主导。顺应火的特性而主运动。运动则诸阳之气生发。女子以阴气为主导。顺应水的特性而主安静。安静则众阴之气汇聚。因此，治疗男子，不要过度使用温热药物来助长其阳气；治疗女子，不要过度使用寒凉药物来增益其阴气。古人将黄柏、知母等药物常用于男子，而干姜、艾叶等方剂则谨慎地施用于妇人。男女阴阳自然的体质，本来就有不能等同对待的地方。至于七情（喜、怒、忧、思、悲、恐、惊）内伤，六淫（风、寒、暑、湿、燥、火）外侵，引发各种疾病，治疗热证用寒药，治疗寒证用热药，随着证候的变化而变化，怎么能拘泥于上述原则呢？只是男女生育稍迟，虽然没有疾病，也应当加以调养护理。男子是阳气主动的体质，只担心性交时容易泄精，未能达到受孕的关键要点；女子是阴气主静的体质，多苦恼性交后不能怀孕，无法完成生命的孕育过程。因此，培养身体的方法，不可废弃。对于男子，则使用思仙丹，收敛固摄真阴，作为持久的打算；对于女子，则使用启荣丸，鼓动微弱的阳气，作为发育的基础。我观察古今用于求子的各方，不是偏于寒性，就是偏于热性，务必夸大其功效以向世人夸耀，却不剖析其中的道理以告知众人。往往服用后反而招致追求完美却失败的毁谤。所以记述这两个方子，以此帮助世间求嗣的人。
适宜旺盛相合的吉日：
春季甲日、乙日、寅日、卯日；夏季丙日、丁日、巳日、午日；秋季庚日、辛日、申日、酉日；冬季壬日、癸日、亥日、子日。
忌讳弦月、望月、晦日、朔日。大风大雨、彩虹霓虹、雷电交加、云雾昏暗、日月食。以及在三光（日、月、星）之下，还有春秋冬三季的丙日、丁日。本命年也是劳碌之日，也不可行房事。上面这些情况都要谨慎小心。
实阳能入虚阴之图 [图片]
所谓“实阳能入虚阴”，是指男子阳精充实，正值女子月经后血海空虚安静，子宫正张开，与之交合，这叫做投于虚空之处，一举就能成胎。
月经干净后第一天交合者生男孩，第二天生女孩，第三天生男孩，第四天生女孩，第五天生男孩，第六天生女孩。这是取奇数为阳、偶数为阴的道理。第六天就不用了。大抵前三天，新血尚未旺盛，精气胜过血液，血液张开包裹精气，必定形成男胎。后三天，新血逐渐增长，血液胜过精气，精气张开包裹血液，多形成女胎。交合得到半夜以后生气的时候，有子皆男且长寿。
实阴不能受阳之图 [图片]
所谓“实阴不能受阳”，是指女子月经结束六天之后，新血正旺盛，血海充满，如果此时交合，是以实投实，多不能成胎。又有妇人素来禀赋怯弱，虽然月经后十天，血海未满，也能成胎，但都是生女孩，这也是因为血胜过精的缘故。
弱阴不能摄阳之图 [图片]
所谓“弱阴不能摄阳”，是指女子阴血衰弱，虽然投入真阳强盛的精气，也不能摄入子宫。因此性交而不怀孕，怀孕而不能养育胎儿。或者因病后、产后、经后，调理失当，劳动过度，亏损阴血所致。治疗宜调经养血。
微阳不能射阴之图 [图片]
所谓“微阳不能射阴”，是指男子阳精微薄，虽然遇到女子血海空虚安静的日子，流出不射精，多不能成胎。这是因为平时嗜欲不节制，施泄太多所致。方法应当补益精元，兼用功夫存养，不让妄动，等到阳精充实，才传授投于虚空的方法，一举就能成胎。
两尺脉洪大或数，小便常赤，未交合时已勃起，既交合即泄，或自遗、梦遗，真精不固，治疗在于补阴。
两尺脉微或迟，小便常清，阳事不举，勉强入房，未竟先痿，或所泄清冷微薄，治疗在于补阳。
Males are governed by Yang Qi. Following the nature of Fire, they are active in movement. Movement generates all Yang energies. Females are governed by Yin Qi. Following the nature of Water, they are tranquil in stillness. Stillness gathers all Yin energies. Therefore, when treating males, one should not excessively use warm and hot herbs to assist their Yang; when treating females, one should not excessively use cold and cool herbs to benefit their Yin. In ancient times, herbs such as Huangbai (Phellodendri Cortex) and Zhimu (Anemarrhenae Rhizoma) were often used for males, while formulas containing Ganjiang (Zingiberis Rhizoma) and Aiye (Artemisiae Argyi Folium) were applied cautiously to women. The natural constitutions of male and female Yin and Yang inherently differ and cannot be treated identically. However, regarding internal injuries from the Seven Emotions (Joy, Anger, Worry, Thought, Sorrow, Fear, Fright) and external invasions by the Six Excesses (Wind, Cold, Summer-heat, Dampness, Dryness, Fire) that manifest as various diseases, heat is treated with cold, and cold is treated with heat, shifting according to the syndrome. How can one rigidly adhere to these principles? Nevertheless, if conception is slightly delayed, even without disease, regulation and care should be added. Males, being Yang-active in constitution, worry about premature ejaculation during intercourse, failing to hit the critical point for conception. Females, being Yin-still in constitution, often suffer from infertility despite intercourse, unable to complete the process of generation. Thus, methods of nurturing the body cannot be abandoned. For males, Sixian Dan (Thought Immortal Pill) is used to consolidate and secure True Yin, planning for endurance. For females, Qirong Wan (Prosperity Initiating Pill) is used to stimulate slight Yang, laying the foundation for development. Observing ancient and modern formulas for seed-conception, none avoid bias towards either cold or heat; they strive to exaggerate their efficacy to boast before the world, without analyzing the principles to show others. Often, taking them leads to criticism for seeking perfection but failing. Therefore, I record these two formulas to assist those seeking offspring in the world.
Auspicious Days for Vigor:
Spring: Jia, Yi, Yin, Mao days; Summer: Bing, Ding, Si, Wu days; Autumn: Geng, Xin, Shen, You days; Winter: Ren, Gui, Hai, Zi days.
Taboo: First quarter moon, full moon, last day of lunar month, first day of lunar month. Strong winds, heavy rain, rainbows, thunderstorms, cloudy/foggy darkness, solar/lunar eclipses. Under the light of the Sun, Moon, and Stars. Also, Bing and Ding days in Spring, Autumn, and Winter. One's birth year is also a day of toil and labor, and intercourse should not occur. One must be cautious regarding the above.
[Image: Diagram of Solid Yang Entering Empty Yin]
"Solid Yang entering Empty Yin" refers to the situation where the male's Yang essence is substantial, coinciding with the female's post-menstrual state where the Blood Sea is empty and quiet, and the uterus is open. Intercourse at this time is termed "casting into emptiness," resulting in conception in one act.
Intercourse on the first day after menstruation ends results in a male child; on the second day, a female; third day, male; fourth day, female; fifth day, male; sixth day, female. This follows the principle of odd numbers being Yang and even numbers being Yin. The sixth day is useless. Generally, in the first three days, new blood is not yet abundant; essence surpasses blood, and blood opens to wrap essence, inevitably forming a male fetus. In the latter three days, new blood gradually grows; blood surpasses essence, and essence opens to wrap blood, mostly forming a female fetus. Intercourse occurring after midnight, during the time of generating Qi, results in sons who are male and long-lived.
[Image: Diagram of Solid Yin Unable to Receive Yang]
"Solid Yin unable to receive Yang" refers to the period six days after the end of menstruation, when new blood is vigorous and the Blood Sea is full. If intercourse occurs then, it is "solid meeting solid," and conception rarely happens. Additionally, some women have a naturally weak constitution; even ten days after menstruation, if the Blood Sea is not full, conception may still occur, but it will likely result in a daughter, again because blood surpasses essence.
[Image: Diagram of Weak Yin Unable to Grasp Yang]
"Weak Yin unable to grasp Yang" refers to the condition where the female's Yin blood is weak. Even if strong Yang essence is introduced, it cannot be grasped by the uterus. Thus, intercourse fails to produce pregnancy, or pregnancy fails to sustain fetal development. This is often caused by improper management after illness, postpartum, or post-menstruation, excessive labor, and depletion of Yin blood. Treatment should focus on regulating menstruation and nourishing blood.
[Image: Diagram of Slight Yang Unable to Shoot Yin]
"Slight Yang unable to shoot Yin" refers to the condition where the male's Yang essence is meager. Even if he encounters the female's post-menstrual empty and quiet state, the essence flows out without ejaculating, and conception rarely occurs. This is due to immoderate desires and excessive emission in daily life. The method is to tonify and benefit the Jing Yuan (Essence Origin), combine with mental cultivation practices to prevent reckless movement, wait until Yang essence is substantial, and then apply the method of "casting into emptiness" to achieve conception in one act.
If the Chi pulse (both wrists) is surging or rapid, urine is frequently red, erection occurs before intercourse, ejaculation occurs immediately upon intercourse, or there is spontaneous emission or nocturnal emission, indicating unstable True Essence, treatment lies in nourishing Yin.
If the Chi pulse is faint or slow, urine is frequently clear, erectile dysfunction occurs, forced intercourse leads to impotence before completion, or the emitted fluid is clear, cold, and meager, treatment lies in tonifying Yang.
