大生要旨云∶天地之道，只贵和平，太热则阳亢，太寒则阴凝。阴凝肃杀，人果知
之。阳亢消烁，人都不察。常见世之艰于子嗣者，构觅传方，希图种子。其方大抵兴阳
壮热之品居多，甚至锻炼金石，及制取毒秽悍劣诸物，劫尽其阴，以为培阳。益以房帏
重耗，渐至髓消肉减，神昏气夺，毛瘁色枯，尚不知为药所误，可胜道哉！
陈成卿曰∶养生家言男淫损人，尤倍于女。盖男为阳，两阳相亢，必竭其精，精竭
则寒，寒则不能生育，故求嗣者当首戒男淫。且谷道为幽冷秽浊之地，屡屡犯之，气偏为
戾。纵阳未衰而有子，非生而不育，即长亦为败家之子。知以后嗣为重者，可不畏乎？况
溺于此者，或痿废，或失明，未老先衰，不一而足，是以有子者亦当深戒也。人能痛自
改悔，誓不再蹈前非，外资药力，内养生机，久久坚持，阳和渐复，不特宁馨有庆，且康
寿可期矣。
褚尚书求男论云∶建平孝王妃姬，皆丽无子。择民家未笄女子入御，又无子。问曰∶
求男有道乎？澄对曰∶合男女必当其年，男虽十六而精通，必三十而娶，女虽十四而天
癸至，必二十而嫁，皆欲阴阳完实，然后交而孕，孕而育，育而子。坚壮强寿，今未笄
之女，天癸始至，已近男色，阴气早泄，未完而伤，未实而动，是以交而不孕，孕而不
育，育而子脆不寿，此王之所以无子也。然妇人有所产皆女者，有所产皆男者，大王诚
能访求多男妇人至宫府，有男之道也。王曰∶善。未再期，生六男。夫老阳遇少阴，老阴
遇少阳，亦有子之道也。
《大生要旨》说：天地的规律，最可贵的是平和，过于炎热则阳气亢盛，过于寒冷则阴气凝滞。阴气凝滞带来肃杀之气，人们如果知道这一点（就会避免）。但阳气亢盛会消耗津液，人们却都不察觉。常见世间难以生育的人，四处寻找传下来的药方，希望求得子嗣。这些药方大多含有兴阳壮热的药物，甚至炼制金石，以及制作有毒、污秽、猛烈劣质的各种物品，强行耗尽阴精，以此来培补阳气。再加上房事过度耗损，逐渐导致骨髓枯竭、肌肉消瘦、神志昏沉、元气夺失、毛发憔悴、面色枯槁，还不知道这是被药物所误害，这哪里说得完呢！
陈成卿说：养生家认为男子纵欲损害身体，尤其比女子严重。因为男子属阳，两阳相亢，必然竭尽精气，精气竭尽则产生寒象，有寒象就不能生育，所以求子的人应当首先戒除男子纵欲。而且肛门是幽冷污秽之地，屡屡触犯它，气机就会偏颇成为邪戾之气。即使阳气未衰而有子嗣，也不是生下来不能养育，就是长大后也是败家的儿子。知道以后代繁衍重要的人，能不畏惧吗？况且沉溺于此的人，有的阳痿废用，有的失明，未老先衰，情况不一而足，所以已有子嗣的人也应当深深戒除。人如果能痛切地自我悔改，发誓不再重蹈覆辙，外在借助药力，内在调养生机，长久坚持，阳气和平之气逐渐恢复，不仅会有健康可爱的孩子值得庆贺，而且健康长寿也可以期待了。
褚尚书《求男论》说：建平孝王的妃嫔姬妾，都美丽却没有子嗣。挑选民间未行笄礼的女子入宫侍奉，又没有子嗣。问说：求取男丁有道吗？澄回答说：男女结合必须适龄，男子虽然十六岁精通精液，但必须三十岁才娶妻；女子虽然十四岁天癸（月经）初至，但必须二十岁才出嫁。这都是想要阴阳气血完备充实，然后交合而受孕，受孕而孕育，孕育而生子。这样生下的孩子才会坚固强壮、寿命长久。现在那些未行笄礼的少女，天癸刚刚到来，就已经接近男子，阴气过早泄露，身体未完备而受伤，未充实而妄动，所以是交合而不能受孕，受孕而不能养育，养育而生下的孩子脆弱不长寿，这就是王没有子嗣的原因。然而妇人有所产皆女的情况，有所产皆男的情况，大王如果能访求多生男孩的妇人到宫府中，这是得男的方法。王说：好。不到一年，生了六个男孩。老阳遇到少阴，老阴遇到少阳，也是有子嗣的方法啊。
*Da Sheng Yao Zhi* (Essentials for Great Birth) states: The way of Heaven and Earth values peace and harmony above all. Excessive heat leads to hyperactive Yang, while excessive cold leads to coagulated Yin. Coagulated Yin brings about a withering and killing energy; if people were aware of this, they would avoid it. However, hyperactive Yang consumes and melts away the body's fluids, yet people rarely notice this. It is common to see those who struggle with infertility seeking out transmitted prescriptions in hopes of conceiving. These prescriptions mostly consist of herbs that stimulate Yang and increase heat, even involving refined minerals and metals, or prepared toxic, filthy, fierce, and inferior substances, forcibly exhausting Yin essence to cultivate Yang. Coupled with heavy depletion from sexual intercourse, this gradually leads to exhaustion of marrow, loss of muscle mass, mental confusion, loss of Qi, brittle hair, and withered complexion. Yet, they remain unaware that they have been misled by these medicines—how can such cases be fully recounted!
Chen Chengqing said: Health preservation experts state that male licentiousness damages the body more than twice as much as female licentiousness. This is because males belong to Yang; when two Yangs interact excessively, essence must be exhausted. When essence is exhausted, cold arises; with cold, fertility is impossible. Therefore, those seeking offspring should first戒 (abstain from) male licentiousness. Moreover, the anus is a dark, cold, and filthy place. Repeatedly violating it causes Qi to become deviant and malignant. Even if Yang is not yet depleted and offspring are produced, they may either fail to survive after birth or grow up to be ruinous sons. Those who value the continuation of their lineage should certainly fear this. Furthermore, those indulging in this practice may suffer from impotence and disability, blindness, or premature aging, among other issues. Thus, even those who already have children should deeply abstain from it. If a person can sincerely repent, vow never to repeat past mistakes, rely externally on medicinal power, and internally nurture vital energy, persisting over time, the harmonious Yang will gradually recover. Not only will there be healthy and auspicious children to celebrate, but health and longevity can also be expected.
In Chu Shangshu's *Lun Qiu Nan* (Discourse on Seeking Male Offspring): The concubines of Princess Xiao of Jianping were all beautiful but childless. He selected young women from the populace who had not yet undergone the capping ceremony (Ji Li) to serve in the palace, yet still no children were born. He asked: "Is there a method to seek male offspring?" Cheng replied: "The union of man and woman must occur at the appropriate age. Although a man may emit semen at sixteen, he should not marry until thirty; although a woman's Tian Gui (menstruation) may begin at fourteen, she should not marry until twenty. This ensures that both Yin and Yang are complete and solid before intercourse, leading to conception, gestation, and childbirth. The resulting child will be robust and long-lived. Now, girls who have not yet undergone the Ji Li ceremony have just begun their Tian Gui; if they approach men prematurely, their Yin Qi leaks too early. Their bodies are incomplete and thus injured, and their essence is not yet full but moves recklessly. Consequently, intercourse fails to result in pregnancy, pregnancy fails to result in viable offspring, or offspring are weak and short-lived. This is why the Prince had no children. However, some women give birth only to daughters, while others give birth only to sons. If Your Highness could indeed find women in the palace who have borne many sons, that would be the way to obtain male offspring." The Prince said: "Excellent." Within less than a year, six boys were born. The meeting of Old Yang with Young Yin, or Old Yin with Young Yang, is also a way to have offspring.
