（素问平人气象论 阴阳别论）
妇人手少阴脉动甚者，任子也。（素问平人气象论。手少阴，心脉也。脉要精微论曰∶上附上，左外以候心。故心脉
当诊于左寸。动甚者，流利滑动也。心生血，血旺乃能胎，妇人心脉动甚者，血旺而然，故当妊子。启玄子云∶手少阴
脉，谓掌后陷者中，当小指动而应手者也。盖指心经之脉，即神门穴也，其说甚善；然以余之验，左寸亦应。任，妊同，
孕也。）
阴搏阳别，谓之有子。（素问阴阳别论。阴，如前手少阴也，或兼足少阴而言亦可。盖心主血，肾主子宫，皆胎孕之
所主也。搏，搏击于手也。阳别者，言阴脉搏手，似乎阳邪，然其鼓动滑利，本非邪脉，盖以阴中见阳而别有和调之象，
是谓阴搏阳别也。腹中论曰∶何以知怀子之且生也？曰∶身有病而无邪脉也。亦此之义。王氏脉经曰∶尺中之脉，按之
不绝，法妊娠也。滑伯仁曰∶三部脉浮沉正等，无他病而不月者，妊也。愚按∶妊子有子之义，乃男子女子之通称。盖
本经以孕育为言，而于男女皆称子，非男曰子而女则否也，后世以此为男子者非。然本经未分男女，而男女之别将何如？
考之叔和脉经曰∶左疾为男，右疾为女。又曰∶左手沉实为男，右手浮大为女。又曰∶尺脉左偏大为男，右偏大为女。
又曰；得太阴脉为男，得太阳脉为女；太阴脉沉，太阳脉浮。自后凡言妊脉者，总不出此。及滑伯仁则曰∶左手尺脉洪
大为男，右手沉实为女。近代徐东皋曰∶男女之别，须审阴阳。右肺盛，阴状多，俱主弄瓦；左尺盛，阳状多，俱主弄
璋。备察诸义，固已详尽；然多彼此矛盾，难以凭据。若其不易之理，则在阴阳二字。以左右分阴阳，则左为阳右为阴；
以寸尺分阴阳，则寸为阳尺为阴；以脉体分阴阳，则鼓搏沉实为阳，虚弱浮涩为阴；诸阳实者为男，诸阴虚者为女，庶
为一定之论。然犹当察孕妇之强弱老少，及平日之偏左偏右，尺寸之素强素弱，斯足以尽其妙也。）
（出自《素问·平人气象论》和《阴阳别论》）
妇女手少阴心脉跳动明显滑利有力的，是怀孕的征象。（《素问·平人气象论》。手少阴脉，即心脉。《脉要精微论》说：在寸口脉的上部，左手外侧候心。所以心脉应当在左寸部诊察。所谓“动甚”，是指脉搏流利、滑动。心主生血，血液旺盛才能滋养胎元，妇女心脉跳动滑利有力，是因为血液旺盛所致，所以应当是怀孕了。启玄子说：手少阴脉，指的是手掌后横纹凹陷处，当小指侧搏动应手的地方。这指的是心经的经脉，也就是神门穴，这种说法很有道理；但根据我的临床经验，左寸部也应当有反应。“任”与“妊”同义，即怀孕的意思。）
尺部阴脉搏击有力，与阳脉有所区别，称为怀孕。（《素问·阴阳别论》。这里的“阴”，如前文所说的手少阴脉，或者兼指足少阴肾脉也可以。因为心主血，肾主子宫，都是主管胎孕的脏腑。“搏”，指脉搏搏击于手指之下。“阳别”，是说阴脉搏指有力，似乎像阳邪之脉，但其鼓动滑利，本来不是病邪之脉，而是因为阴中见阳，呈现出一种别有调和的景象，这就叫做“阴搏阳别”。《素问·腹中论》说：怎么知道女子将要分娩呢？回答说：身体虽有不适症状但没有邪脉。也是这个意思。王叔和的《脉经》说：尺部的脉搏，按之不绝，这是妊娠的法度。滑伯仁说：三部脉浮沉力度相当，没有其他疾病而月经停止的，就是怀孕。我认为：“妊子”即“有子”的意思，是男女通用的称呼。因为本经是以孕育为话题，所以对男女都称为“子”，并不是只有男子叫“子”而女子不叫，后世认为这是专指男子的说法是不对的。然而本经没有区分男女，那么如何区分男女呢？考察王叔和的《脉经》说：左手脉疾数为男，右手脉疾数为女。又说：左手脉沉实为男，右手脉浮大为女。又说：尺脉左侧偏大为男，右侧偏大为女。又说：得太阴脉为男，得太阳脉为女；太阴脉沉，太阳脉浮。此后凡是谈论妊娠脉象的，总不出这些范围。到了滑伯仁则说：左手尺脉洪大为男，右手沉实为女。近代徐东皋说：区分男女，必须审察阴阳。右肺脉盛，阴状多，都主生女（弄瓦）；左尺脉盛，阳状多，都主生男（弄璋）。详细考察各种说法，固然已经详尽；但是彼此矛盾，难以作为依据。如果其中有不易改变的道理，就在于“阴阳”二字。以左右分阴阳，则左为阳右为阴；以寸尺分阴阳，则寸为阳尺为阴；以脉体分阴阳，则鼓搏沉实为阳，虚弱浮涩为阴；诸阳实者为男，诸阴虚者为女，这才是确定的理论。然而还应当观察孕妇的强弱老少，以及平日脉象偏左还是偏右，尺寸脉原本强还是弱，这样才能穷尽其中的奥妙。）
(From *Suwen: Pingren Qixiang Lun* and *Yinyang Bie Lun*)
If the Hand-Shaoyin pulse in a woman is markedly vigorous and slippery, it indicates pregnancy. (*Suwen: Pingren Qixiang Lun*. The Hand-Shaoyin pulse refers to the Heart pulse. *Ma Yao Jing Wei Lun* states: "At the upper level of the cun position, the lateral side on the left corresponds to the Heart." Therefore, the Heart pulse should be palpated at the left Cun position. "Vigorous" (Dong Shen) refers to a smooth and slippery quality. The Heart governs blood generation; abundant blood is necessary to nourish the fetus. When a woman's Heart pulse is vigorous and slippery, it results from abundant blood, thus indicating pregnancy. Qixuanzi stated: "The Hand-Shaoyin pulse refers to the depression behind the palm, where pulsation is felt when pressing near the little finger." This refers to the Heart meridian, specifically the Shenmen acupoint (Shenmen), which is a sound interpretation; however, based on my clinical experience, the left Cun position should also respond. "Ren" is synonymous with "Ren" (pregnancy).)
When the Yin pulse beats vigorously and differs distinctly from the Yang pulse, it is called having a child. (*Suwen: Yinyang Bie Lun*. Here, "Yin" refers to the Hand-Shaoyin pulse mentioned earlier, or may also include the Foot-Shaoyin pulse. This is because the Heart governs blood, and the Kidney governs the uterus; both are organs primarily responsible for gestation. "Bo" means the pulse strikes against the fingers. "Yang Bie" implies that although the Yin pulse feels vigorous like a Yang pathogen, its beating is smooth and slippery, inherently not a pathological pulse. Instead, it shows a harmonious image where Yang appears within Yin, termed "Yin Bo Yang Bie". *Fuzhong Lun* asks: "How do we know a woman is about to give birth?" The answer is: "The body has symptoms but no pathogenic pulses." This conveys the same meaning. Wang Shuhe's *Mai Jing* states: "If the Chi pulse remains unceasing upon pressure, it is the method for diagnosing pregnancy." Hua Bolin stated: "If the pulses at all three positions (Cun, Guan, Chi) are equal in floating and sinking depth, there are no other diseases, yet menstruation has ceased, it is pregnancy." I observe that "Ren Zi" (pregnant child) shares the meaning of "You Zi" (having a child), serving as a general term for both men and women in this context. Since the classic text discusses conception, it uses "Zi" for both genders; it does not mean "Zi" applies only to males while excluding females. Later interpretations claiming this refers exclusively to males are incorrect. However, since the classic text does not distinguish between sexes, how can one differentiate? Examining Wang Shuhe's *Mai Jing*: "Rapid pulse on the left indicates a male; rapid pulse on the right indicates a female." It further states: "Deep and solid pulse on the left indicates a male; floating and large pulse on the right indicates a female." Also: "Chi pulse enlarged on the left indicates a male; enlarged on the right indicates a female." And: "Obtaining the Taiyin pulse indicates a male; obtaining the Taiyang pulse indicates a female; Taiyin pulse is deep, Taiyang pulse is floating." Subsequent discussions on pregnancy pulses generally adhere to these principles. Later, Hua Bolin stated: "Large and vigorous Chi pulse on the left indicates a male; deep and solid pulse on the right indicates a female." Xu Donggao of recent times stated: "To distinguish between male and female, one must examine Yin and Yang. If the Lung pulse on the right is strong, showing more Yin characteristics, it indicates a daughter (playing with tiles); if the left Chi pulse is strong, showing more Yang characteristics, it indicates a son (playing with jade)." While examining all these theories is thorough, they often contradict each other and are difficult to rely upon. If there is an immutable principle, it lies in the concept of Yin and Yang. Differentiating by left and right: Left is Yang, Right is Yin. Differentiating by Cun and Chi: Cun is Yang, Chi is Yin. Differentiating by pulse morphology: Vigorous, deep, and solid pulses are Yang; weak, floating, and choppy pulses are Yin. Generally, Yang-excess pulses indicate a male, and Yin-deficiency pulses indicate a female. This constitutes a fixed theory. Nevertheless, one must still observe the strength, age, and constitution of the pregnant woman, as well as whether her habitual pulse favors the left or right, and whether the Cun or Chi positions are naturally strong or weak, to fully grasp the subtleties.)
