黄帝曰∶妇人有彻老不生男女，何也？曰∶因多房事，损动脏腑；或天癸不通，子宫挟寒；
或男子事狂，阳弱精少，清寒不能射，又不既济而相接，此所以不生也。或有正生产，断六、七
年，数岁不生，何也？亦由女人有上数疾，劳损身体，以致经脉不调，虽有亦微弱，难以容纳阳
精也。且夫妇之道，交合以时，生子必壮，聪慧永寿。古人有图，择生男之月，而王隐君谓春取
甲乙日，夏丙丁、秋庚辛、冬壬癸，四季月后各十八日。取戊己为旺相日，及天月二德诸吉日，
论时，则取妇人经行适当三十时。诀
云∶三十时辰两日半，二十八、九君须算，落红满地是佳期，金水过时空霍乱。霍乱之时枉费工
，树头树底觅残红，但解花开能结子，何愁丹桂不成丛。此云妇人月经方止，金水初生时，子宫
正开，乃受精结胎之候，妙合太和之际，宜以人事副之，庶不失造化之理也。过此佳期，则子宫
闭而不受胎矣。然妇人经水耒时，有两日半净者，有三、五、七日净者，惟以败血去尽，新血初
生，但以洁白布帛拭之。如鲜红者，未尽也；浅淡者，太过也；看新血如金色者，正当时也，交
合无不成孕。更宜净后一、三、五日成男，双日成女，宜子时后，得遇天月二德及诸吉辰，不近
秽污，择净洁之处，则有福德善慧灵光托化，得子必神气清秀，聪慧胜人。又云∶男子施精向左
，女子屈左足，而左侧卧成男。胎成之后，不宜连续交合，最宜安静调养，乃保弥月而诞生福寿
之子嗣矣。或曰∶女子受孕，此常道也，何苦是之难乎？曰∶大矣哉！人之有生也，其阴阳造化
之妙乎。夫阴阳生生不息之德，其在于物，则本乎乾坤；其在于人，则根乎精血。是故虽有道体
之妙，而实遇修用之机。自其常而观之，则愚夫愚妇无不知也；自其变而言之，虽博综之士，亦
有所不能焉。是故体则阴阳精血，用则阴阳配合也。精血盈足；配合中时，此其常也，及其变也
，当忝所以变之理。达人君子，可不于有变之际而加意焉。子嗣之求，研究圣贤之蕴，以赞化育
之机者也。世之人知所以用，则螽斯兆于此矣。锡祚永之胤，终大地之功，岂小补云。俗有男子
精气未足，女子经脉未通，而成合HT 之体，男子有成劳怯，女子多成崩淋。虽不能如古人男子三
十，女子二十为父母者，必待男成冠纳室，女及笄于归，自成孕育，分娩无虞。蕃衍胤嗣，更何
病之有哉？
妇人不孕，不可概谓子宫虚寒冷闭，而通用温热之药。有体瘦而多气郁，全是内火煎熬，阴
血津液
枯涸，但宜滋阴养血，兼以清热乃效。若全用温热之药，则阴血愈亏，非惟无孕，变生他病，祸
不旋踵矣。脉法沉涩，气郁；洪数，内火；微迟，虚寒。微弱细涩，气血两虚，少年无孕，中年
绝产。六脉相停，滑而和乃成孕。

黄帝问道：妇女到了老年不再生育子女，这是为什么呢？回答说：因为房事过多，损伤了脏腑；或者天癸（指促进生殖机能成熟的物质）不通畅，子宫夹带寒气；或者男子纵欲过度，阳气虚弱、精液稀少，清冷的精气无法射出，又没有达到阴阳既济的状态就进行交接，这就是不能生育的原因。有的妇女刚生产完，断绝性生活六七年，多年不怀孕，这是为什么呢？也是由于妇女患有上述几种疾病，劳累损耗身体，导致经脉不调，即使有受孕机会也很微弱，难以容纳阳精。况且夫妇之道，交合要合乎时机，生下的孩子一定强壮、聪慧且长寿。古人有图说，选择生男孩的月份，而王隐君说春季选取甲乙日，夏季丙丁日，秋季庚辛日，冬季壬癸日，四季的最后十八天为土旺之日。选取戊己日为旺盛相宜的日子，以及天德、月德等吉日，论及时辰，则选取妇人月经行将结束后的适当三十个时辰。诀云：“三十时辰两日半，二十八、九君须算，落红满地是佳期，金水过时空霍乱。”霍乱之时枉费工夫，只能在树头树底寻找残红。只要懂得花开能结子，何必担心丹桂不成丛。这里说的是妇人月经刚刚停止，金水（指肾阴/经血初生）刚开始生长的时候，子宫正开放，乃是受精结胎的候机，妙合太和之际，应当以人事来顺应它，才不会违背造化的道理。过了这个佳期，子宫就会闭合而不受胎了。然而妇人在经水未净时，有两日半干净的，有三、五、七天干净的，只以败血去尽、新血初生为标准，用洁白的布帛擦拭。如果颜色鲜红，说明血未尽；颜色浅淡，说明时间过长；看新血如金色者，正是正当时候，交合没有不成孕的。更适宜在净后的一、三、五日同房生男孩，双日生女孩，宜在子时之后，遇到天月二德及诸吉辰，不接近秽污，选择洁净之处，则有福德善慧灵光托化，得子必定神气清秀，聪慧过人。又说：男子施精向左，女子屈左足，左侧卧位可生男孩。胎成之后，不宜连续交合，最宜安静调养，这样才能保全十月孕期，诞生福寿之子嗣。有人说：女子受孕，这是常道，为什么觉得这么难呢？回答说：大啊！人的生存，在于阴阳造化的奥妙吧。那阴阳生生不息的德行，对于万物来说，根本在于乾坤；对于人来说，根本在于精血。因此虽然有道的体悟之妙，但实际遇到修行的契机。从常规来看，愚夫愚妇没有不知道的；从变化来说，即使是博学通晓的人，也有做不到的地方。所以体用而言，就是阴阳精血，应用而言，就是阴阳配合。精血充盈充足，配合中于时机，这是常态；至于变化，应当探究变化的道理。通达的君子，难道不在变化之际加以留意吗？求取子嗣，是研究圣贤深蕴，以赞助造化之机运的事。世人知道如何运用，那么螽斯（比喻子孙众多）的征兆就在这里了。赐予长久的福泽给后代，完成大地养育万物的功绩，岂止是小补而已。世俗中有男子精气未足，女子经脉未通，就形成合卺（指结婚或性交）的身体，男子多形成虚劳怯弱之症，女子多形成崩漏淋证。虽然不能像古人所说男子三十岁、女子二十岁做父母那样早婚，但必须等到男子行冠礼娶妻，女子及笄出嫁，自然能孕育，分娩无虞。繁衍子嗣，还有什么病呢？
妇人不孕，不可一概说是子宫虚寒冷闭，而通用温热药物。有体质瘦弱且多气郁的，全是内火煎熬，阴血津液枯涸，只宜滋阴养血，兼以清热才有效。如果全用温热药物，则阴血更加亏损，不仅不能怀孕，还会变生其他疾病，祸患立刻到来。脉法：沉涩，主气郁；洪数，主内火；微迟，主虚寒。微弱细涩，主气血两虚，少年无孕，中年绝产。六脉相停，滑而和缓乃成孕。
主方（男服）：秋石（四两）、鹿角霜（四两）、人参、枸杞子（甘州产）、山茱萸肉、麦冬、天门冬、杜仲（姜炒至断丝）、生地黄、熟地黄（酒蒸。各二两）。以上研为末，老米粉作糊丸，如梧桐子大。每服五十丸，空腹白开水送下。一个月后，等候女子月经经过，金水正生时，男子空腹服车前子汤半盏，夜间交合即可得孕。随时再以前方参酌调制兼服。
主方（女服）：香附子（一斤，四制：春、秋三；夏二；冬七日；晒干为末，筛去头末，取中末半斤用）、当归（酒浸）、白术（土炒。各三两）、川芎、白芍药、熟地黄、生地黄、阿胶、丹皮、黄芩（炒）、益母草、柴胡、臭椿根白皮（各二两）。以上研末，醋糊丸如梧桐子大，每六十丸空腹淡醋汤送下，用干食压之。
Huangdi asked: Why do women cease to bear children when they grow old? The answer is: It is due to excessive sexual intercourse, which damages the Zang-Fu organs; or because Tian Gui (the substance promoting reproductive maturity) is blocked, and the uterus harbors cold; or because the man indulges in lust, resulting in weak Yang and scanty essence, where the clear and cold essence cannot be ejaculated, and union occurs without achieving the state of Ji Ji (balance of Yin and Yang), thus causing infertility. If a woman has just given birth and abstains from intercourse for six or seven years, remaining childless for several years, why is this? It is also due to the woman suffering from the aforementioned ailments, leading to physical exhaustion and disharmony of the meridians. Even if conception is possible, it is weak and difficult to retain the Yang essence. Moreover, marital union should follow proper timing; offspring born from such unions will be strong, intelligent, and long-lived. Ancient diagrams suggest selecting months for conceiving sons. Wang Yinjun stated that in Spring one should select Jia and Yi days, in Summer Bing and Ding days, in Autumn Geng and Xin days, and in Winter Ren and Gui days, with the last eighteen days of each season being Earth-waning days. One should select Wu and Ji days as prosperous and auspicious days, as well as Tian De (Heavenly Virtue) and Yue De (Monthly Virtue) days. Regarding hours, one should select the appropriate thirty Shi Chen (two-hour periods) after the woman's menstruation ends. The verse says: "Thirty Shi Chen make two and a half days, calculate twenty-eight or twenty-nine carefully. When red drops cover the ground, it is the best time; when Jin Shui (Metal and Water/Yin blood) passes, chaos ensues." Wasting effort during chaos is futile; one must look for residual redness under trees and bushes. As long as one understands that flowers blooming can bear fruit, why worry that cinnabar cassia will not form a grove? This refers to the time when the woman's menstruation has just stopped and Jin Shui (initial generation of kidney Yin/menstrual blood) begins to grow. At this moment, the uterus is open, which is the time for fertilization and conception, a moment of harmonious integration. Human actions should accord with this to avoid violating the principles of creation. After this optimal period, the uterus closes and cannot accept conception. However, before menstruation completely stops, some women are clean in two and a half days, others in three, five, or seven days. The standard is whether stale blood is gone and new blood has just begun. Wipe with white cloth. If bright red, blood is not finished; if pale, too much time has passed. If the new blood appears golden, it is the right time, and intercourse will surely lead to pregnancy. Furthermore, intercourse on the 1st, 3rd, or 5th day after cleaning may result in a boy, while even-numbered days may result in a girl. It is best to have intercourse after Zi hour (11 PM–1 AM), encountering Tian De and Yue De or other auspicious times, avoiding filth, and choosing a clean place. This invites blessings and wisdom, ensuring the child is spiritually refined and superior in intelligence. It is also said that if the man ejaculates towards the left, the woman bends her left foot and lies on her left side, a boy will be conceived. After conception, continuous intercourse should be avoided; quiet rest is best to ensure a full-term delivery of a blessed and long-lived child. Someone asks: Conception is a natural law for women; why is it considered so difficult? The answer is: Great indeed! Human life depends on the subtleties of Yin-Yang creation. The virtue of endless generation of Yin and Yang is rooted in Qian and Kun for all things, and in Essence and Blood for humans. Thus, although there is the wonder of Dao, practical application requires seizing the opportunity. From a common perspective, even ordinary people know this; from a variable perspective, even scholars may fail. Therefore, in terms of substance, it is Yin-Yang Essence and Blood; in terms of function, it is the combination of Yin and Yang. When Essence and Blood are abundant and timing is correct, this is the norm. Regarding variations, one must understand the principles of change. Wise gentlemen should pay attention during times of change. Seeking offspring involves studying the profound truths of sages to assist the mechanism of creation. Those who know how to apply this will see the signs of numerous descendants (Zhong Si). Bestowing eternal lineage completes the earth's nurturing work, far more than a small benefit. In俗 custom, men with insufficient essence and women with unregulated menstruation engage in union prematurely, leading to consumption and deficiency in men, and metrorrhagia and leukorrhea in women. Although one cannot marry as early as the ancients suggested (men at 30, women at 20), one must wait until men undergo the Capping ceremony and marry, and women reach their hairpin age and wed, to naturally conceive and deliver safely without fear. With flourishing offspring, what disease would there be?
Infertility in women should not be generally attributed to uterine deficiency-cold and closure, nor treated universally with warming herbs. Some women are thin and suffer from Qi stagnation, with internal fire scorching Yin blood and body fluids dry. For them, only nourishing Yin and blood, combined with clearing heat, is effective. If warming herbs are used exclusively, Yin blood will further deplete, leading not only to infertility but also to other diseases, with disaster following swiftly. Pulse diagnosis: Deep and choppy indicates Qi stagnation; Surging and rapid indicates internal fire; Fine and slow indicates deficiency-cold. Weak, fine, and choppy pulses indicate dual deficiency of Qi and Blood, causing infertility in youth and cessation of reproduction in middle age. Six pulses stopping, yet slippery and harmonious, indicates pregnancy.
