《玉房秘诀》云∶冲和子曰∶夫极情逞欲，必有损伤之病，斯乃交验之着明者也。既以
斯病，亦以斯愈，解酲以酒，足为喻也。
又云∶采女曰∶男之盛衰，何以为候？彭祖曰∶伤盛得气则玉茎当热，阳精浓而凝也。
其衰有五∶一曰精泄而出，则气伤也；二曰精清而少，此肉伤也；三曰精变而臭，此筋伤也；
四曰精出不射，此骨伤也；五曰阴衰不起，此本伤也。凡此众伤，皆由不徐交接，而猝暴施
泻之所致也。治之法，但御而不施，不过百日，气力必致百倍。
又云∶交接开目，相见形体，夜燃火视图书，即病目瞑清盲。治之法，夜闭目而交，愈。
交接取敌人着腹上者，从下举腰应之，则苦腰痛，少腹里急，两脚物背曲。治之法，覆体正
身，徐戏，愈。
交接侧斯，旁向敌手，举敌尻，病胁痛。治之法，正卧徐戏，愈。交接低头延颈则病头
重项强。治之，法，以头置敌人额上，不低之愈。
交接侵饱，谓夜半饭气未消而以戏，即病疮，胸气满，胁下如拔，胸中若裂，不欲饮食，
心下结塞，时呕吐青黄，胃气实，结脉，若衄吐血，若胁下坚痛，面生恶疮。治之法，过夜
半向晨交，愈。
交接侵酒，谓醉而交接，戏用力深极，即病黄胆，黑瘅，胁下痛，有气接，接动手下髀
里，若囊盛水彻脐上，肩膊，甚者胸背痛，咳唾血，上气。治之法，勿复乘酒热向晨交接，
戏徐缓体，愈。
当溺不溺以交接，则病淋，少腹气急，小便难，茎中疼痛，常欲手撮持。须臾，乃欲出。
治之法，先小便，还卧自定，半饭饮久顷，乃徐交接，愈。
当大便不大便而交接，即病痔。大便难，至清，移日月，下脓血，孔旁生疮如蜂穴状，
圊上倾倚，便不时出，疼痛，痈肿，卧不得息，以道。治之法，用鸡鸣际，先起更衣，还卧
自定，徐相戏弄，完体缓意，令滑泽而退。病愈神良。并愈妇病。
交接过度，汗如珠子，屈伸转侧，风生被里，精虚气竭，风邪入体，则病缓弱为跛蹇，
手不上头，治之法，爱养精神，服地黄煎。
又云∶巫子都曰∶令人目明之道，临动欲施时，仰头闭气，大呼， 目，左右视，缩腹

《玉房秘诀》记载：冲和子说：放纵情欲，必定导致身体损伤的疾病，这是非常明显的验证。既然这种病是由纵欲引起的，也可以用节制欲望的方法来治愈，就像用酒来解酒醉一样，足可作为比喻。
又记载：采女问：男性的盛衰，以什么作为征兆？彭祖说：当精力旺盛且得气时，阴茎应当发热，阳精浓稠而凝结。其衰退有五种表现：一是精气泄出，这是气受损；二是精液清稀量少，这是肌肉受损；三是精液变色且有臭味，这是筋受损；四是精液射出无力，这是骨受损；五是阴器痿软不起，这是根本受损。所有这些损伤，都是由于交接时不从容舒缓，而是突然猛烈施泻所致。治疗的方法，只要控制性交而不射精，不超过一百天，气力必然恢复到百倍。
又记载：性交时睁眼，看见对方的形体，夜间点灯看书图，会导致眼睛昏花、视力模糊甚至失明。治疗的方法是，夜间闭目交合，即可痊愈。
性交时采取让女方压在身上的姿势，从下方挺腰迎合，会导致腰痛、小腹部拘急紧绷、两腿弯曲难以伸直。治疗的方法是，仰卧端正身体，缓慢嬉戏，即可痊愈。
性交时侧身，偏向对手的手部，抬起对方的臀部，会导致胁肋疼痛。治疗的方法是，平卧缓慢嬉戏，即可痊愈。性交时低头伸颈，会导致头重项强。治疗方法是，将头放在对方额头上，保持头部不低垂，即可痊愈。
性交时饱食后进行，指半夜饭气未消就进行嬉戏，会导致生疮、胸部胀满、胁下如被拔扯感、胸中似撕裂感、不想饮食、心下痞结堵塞、时常呕吐青黄色液体、胃气实盛、脉象结滞，如果伴有鼻衄或吐血，或者胁下坚硬疼痛、面部生恶疮。治疗的方法是，等到过了半夜接近清晨时再进行交合，即可痊愈。
性交时饮酒后进行，指醉酒状态下交合，嬉戏用力过深极尽，会导致黄疸、黑疸、胁下疼痛、气机阻滞，按压手下髀部内部，感觉像囊袋盛水直到脐上，肩部膊部不适，严重的出现胸背痛、咳嗽唾血、气逆上冲。治疗的方法是，不要再趁着酒热在清晨交合，嬉戏时要缓慢舒展身体，即可痊愈。
有尿意却不排尿而进行交合，会导致淋证、少腹气急、小便困难、尿道疼痛、经常想要用手捏持。片刻后，才想排出。治疗的方法是，先排空小便，然后躺下自我安定，吃完一顿饭的时间后，再缓慢交合，即可痊愈。
有大便意或不排便而进行交合，会导致痔疮。大便困难，甚至排出清水，经过一段时间后，排出脓血，肛门旁生出如蜂巢孔状的疮疡，如厕时倾斜倚靠，大便不时流出，疼痛，痈肿，卧床无法呼吸顺畅，通过肠道传导异常。治疗的方法是，在鸡鸣时分，先起床更衣，然后躺下自我安定，缓慢相互嬉戏玩弄，保全身体，缓和心意，使体液滑润而后退出。病情痊愈，神效良佳。并能同时治愈女性的疾病。
性交过度，汗出如珠，屈伸转侧间，被子里生出风邪，精气虚竭，风邪侵入体内，会导致肢体缓弱成为跛行，手不能举过头顶。治疗的方法是，爱惜保养精神，服用地黄煎。
又记载：巫子都说：使人眼睛明亮的道理，在即将动作施泻时，仰头憋气，大声呼喊，注视双目，左右环视，收缩腹部返还精气，使其进入百脉之中。
使人耳朵不聋的方法，在即将施泻时，大口咽气，咬紧牙齿憋气，使耳中有萧萧声，再次收缩腹部，使气流分布至坚固之处，即使到老也不会耳聋。
调理五脏、消化食物、治疗各种疾病的道理，在施泻前张开腹部，用意念纳入气息，收缩后方防止精散而回归百脉，采用“九浅一深”的手法，到达琴弦、麦齿之间（指阴道深处），正气恢复，邪气散去。使人腰背不痛的方法，背靠墙壁伸展腰部，不要过分低头或仰头，保持腰背平直，事后常令津液流动，可以补虚、养体、治病，想要射精时不要射精，让精气回流，在流动中产生温热。
又记载：阴阳之道，精液为珍贵之物，如果能爱惜它，性命就可以保全。凡是施泻之后，应当摄取女方的气来补益自己，所谓“建九”，就是内息九次。所谓“厌一”，是用左手按住阴下部位，返还精液复归津液。所谓“取气”，就是九浅一深。用口对着对方的口气呼气，用口吸气，微微引导二无（此处疑为衍文或特定术语，暂译作气息）吞咽下去，用意念将气引向下腹。到达腹部是为了助长阴力，如此反复三次，再变浅，实行九浅一深。九九八十一，阳数圆满了。阴茎竖起时插入，软弱时退出，这叫做弱入强出。阴阳的和合，在于琴弦、麦齿之间，阳气困于昆石之下，阴气困于麦齿之间，浅则得气，远则气散。到达谷实（更深部位），会伤肝，见风流泪，小便有余沥。到达臭鼠（更深处），会伤肠肺，咳嗽气逆，腰背痛。到达昆石（最深部位），会伤脾，腹部胀满腥臭，时常腹泻，大腿疼痛，百病生于昆石，所以在交接合欢时不希望达到太深的地方。
黄帝问：触犯这些禁忌，治疗方剂怎么办？子都说：应当用女性来治疗。其法让女方正仰卧，使两腿分开九寸，男方前往从之，先饮用王浆（一种滋补饮品），久久等待精气充盈如鸿泉，然后缓慢纳入阴茎，用手控制节奏，才能刚好到达琴弦、麦齿之间。
女方淫动心烦，常常自行坚持，不要施泻。度过三十个呼吸的时间使其坚强，然后缓慢纳入，令其到达昆石。当极其洪大时，洪大则退出，正常呼吸时虚弱，再纳入，常令弱入强出，不超过十天，坚如铁，热如火，百战不殆。
The *Yufang Mijue* (Secrets of the Jade Chamber) records: Chonghezi said: Indulging in desires inevitably leads to diseases of damage; this is a manifest verification. Since this illness arises from such indulgence, it can also be cured by restraining it, just as wine is used to cure drunkenness, which serves as a sufficient analogy.
It further records: Cai Nu asked: How can one discern the decline or vigor of men? Peng Zu replied: When vigor is abundant and Qi is acquired, the jade stem (penis) should feel hot, and the yang essence will be thick and coagulated. There are five signs of decline: First, if essence leaks out, Qi is damaged; Second, if essence is clear and scanty, flesh (muscles) is damaged; Third, if essence changes color and smells foul, sinews are damaged; Fourth, if essence ejaculates without force, bones are damaged; Fifth, if the yin organ fails to rise, the root (kidney/essence) is damaged. All these damages result from intercourse that is not leisurely but sudden and violent ejaculation. The treatment method is to engage in sexual activity without ejaculating; within a hundred days, strength and Qi will certainly return to a hundredfold.
It further records: During intercourse, keeping eyes open and seeing the partner's body, or reading books/images by candlelight at night, leads to dim vision and blindness. The treatment is to close the eyes during nocturnal intercourse, which leads to recovery.
Adopting a position where the partner lies on top, thrusting the waist from below to meet them, causes lower back pain, urgency and tension in the lower abdomen, and curvature of the legs. The treatment is to lie supine with the body straight and engage in slow play, leading to recovery.
Turning sideways during intercourse, facing the partner's hand, and lifting the partner's buttocks causes flank pain. The treatment is to lie flat and engage in slow play, leading to recovery. Bending the head and extending the neck during intercourse causes heavy head and stiff neck. The treatment is to place the head on the partner's forehead, keeping the head upright, leading to recovery.
Engaging in intercourse when full, specifically playing before midnight when food has not digested, leads to sores, chest fullness, a pulling sensation under the flanks, a tearing sensation in the chest, loss of appetite, epigastric blockage, occasional vomiting of green-yellow fluid, excess stomach Qi, knotted pulse, nasal bleeding or hematemesis, hardness and pain under the flanks, and malignant sores on the face. The treatment is to wait until past midnight towards dawn to engage in intercourse, leading to recovery.
Engaging in intercourse while intoxicated, exerting deep and extreme effort, leads to jaundice, black jaundice, flank pain, qi stagnation, tenderness upon pressing the lower thigh area, a sensation like a water-filled sac reaching above the navel, shoulder discomfort, severe cases involving chest and back pain, coughing up blood, and rising qi. The treatment is to avoid intercourse while drunk or hot, especially in the morning; engage in slow and relaxed physical play, leading to recovery.
Having the urge to urinate but not doing so before intercourse leads to strangury (lin syndrome), urgency in the lower abdomen, difficult urination, pain in the urethra, and a constant desire to grasp the penis. After a moment, there is an urge to void. The treatment is to urinate first, then lie down and calm oneself; after the time it takes to eat a meal, engage in slow intercourse, leading to recovery.
Having the urge to defecate or being constipated while engaging in intercourse leads to hemorrhoids. Difficulty in defecation, passing clear fluid, progressing over days to passing pus and blood, sores around the anus resembling bee hives, leaning on the toilet, involuntary stool passage, pain, abscesses, inability to breathe comfortably while lying down, and abnormal bowel transmission. The treatment is to rise at cockcrow, change clothes, lie down and calm oneself, engage in slow mutual play, preserve the body, relax the mind, ensure lubrication, and withdraw. The disease heals with divine efficacy. It also cures women's diseases.
Excessive intercourse, sweating like pearls, generating wind inside the quilt during movement, depletion of essence and Qi, and invasion of wind pathogens lead to weakness and limping, with hands unable to reach the head. The treatment is to cherish and nourish the spirit, and take Dihuang Jian (Rehmannia Decoction).
Wu Zidu said: To keep eyes bright, when about to move and ejaculate, tilt the head back, hold breath, shout loudly, look left and right, contract the abdomen to return essence and Qi into the hundred vessels.
To prevent deafness, when about to ejaculate, swallow air deeply, clench teeth and hold breath, causing a buzzing sound in the ears, contract the abdomen again to distribute Qi firmly; one will not go deaf even in old age.
To regulate the five zang organs, digest food, and treat various diseases, when about to act, expand the abdomen, use intention to draw in Qi, contract the rear to prevent essence scattering and return it to the hundred vessels. Use the technique of "nine shallow, one deep," reaching between the strings and wheat teeth (deep vaginal areas), restoring righteous Qi and dispersing pathogenic Qi. To prevent back pain, stretch the waist against a wall, do not bow or arch excessively, keep the waist and back level, allow fluids to flow afterwards; this tonifies deficiency, nourishes the body, treats disease. Do not ejaculate when the urge arises; let Qi flow back, generating heat within the flow.
Furthermore, the way of Yin and Yang values essence as precious. If cherished, life can be preserved. After ejaculation, one should absorb the female's Qi for self-nourishment. "Jian Jiu" refers to internal respiration nine times. "Ya Yi" means pressing below the yin with the left hand to return essence and restore fluids. "Qu Qi" (acquiring Qi) refers to the "nine shallow, one deep" technique. Breathe out through the mouth towards the partner's breath, inhale through the mouth, gently guide the Qi down and swallow, using intention to direct Qi to the abdomen. This aids Yin power. Repeat three times, then become shallow, practicing nine shallow, one deep. Nine times nine equals eighty-one, completing the Yang number. Insert when erect, withdraw when soft; this is weak entry and strong exit. The harmony of Yin and Yang lies between the strings and wheat teeth. Yang is confined below Kunshi, Yin is confined between wheat teeth. Shallow access gains Qi; distant access scatters Qi. Reaching Gushi (deep point) damages the Liver, causing tearing in wind, residual urine. Reaching Choushu (deeper point) damages intestines and Lungs, causing cough, rebellious Qi, back pain. Reaching Kunshi (deepest point) damages the Spleen, causing abdominal fullness, foul odor, frequent diarrhea, thigh pain. Hundred diseases arise from Kunshi; thus, one should not aim too deep during intercourse.
The Yellow Emperor asked: What if these prohibitions are violated? How to treat? Zidu said: Treat with the female. Let the woman lie supine with legs spread nine inches apart. The man approaches, first drinks Wangjiang (royal milk/nourishing drink), waits until essence flows like a spring, then slowly inserts the jade stem, controlling with hand rhythm, aiming precisely for the area between strings and wheat teeth.
If the partner is restless and irritable, maintain control and do not ejaculate. After thirty breaths, when firm, slowly insert to Kunshi. When extremely full and large, withdraw; when normal and weak, re-insert. Maintain weak entry and strong exit. Within ten days, firm as iron, hot as fire, invincible in battle.
