《诸病源候论》中说：脉象左手沉实为男，右手浮大为女；左右手都沉实，生两个男孩。左右手都浮大，生两个女孩。又说：让孕妇向南走，然后突然叫她的名字，身体向左回转的是男孩，向右回转的是女孩。又说：如果丈夫的左乳房有硬结是男孩，右乳房有硬结是女孩。

又说：占测怀孕男女的方法：
传说：将传送（神煞名）加在丈夫的本命上，看是否出现在妻子的游年上，得到阳神为男孩，得到阴神为女孩。
一种说法是：天罡、天后加在母亲年龄对应的地支上，或者酉临阳辰，或者功曹临阳；或者天干有气，或者时辰与日干比和，或者阳神临日者，必定是男孩；或者功曹临阴辰，支上有气，都是女孩。
一种说法是：得到青龙、太裳，生的孩子多为男孩。或者得到天后、太阳（属阴），生的孩子多为女孩。
一种说法是：经常用传送加在妇人本命上，年在阳神下为男孩；年在阴神下为女孩。
一种说法是：微明加在四孟（寅申巳亥）为男孩，神后加在四仲（子午卯酉）为女孩。
一种说法是：母亲的行年临四孟为男孩，临四仲四季（子午卯酉及辰戌丑未中的季位，此处指代特定方位或地支组合，原文“四仲季”可能指代非孟之位）为女孩。
一种说法是：腾蛇、朱雀、青龙、勾陈、玄武、白虎，加在日辰上都是男孩。六合、天官（空亡）、大阴、天后、大裳，加在日辰上都是女孩。
一种说法是：直接应用，神在阳位像父亲，在阴位像母亲。或者处于旺相状态，容貌美丽；处于囚休状态，容貌丑陋。

又说：想要知道计算男女的方法，先排下丈夫的年龄，其次排下妻子的年龄，再排下胎月，正月怀孕则排算十二月，总共取十二个月的算数总和。然后减去天一，又减去地二，又减人去三，又减去四时四，又减去五行五，又减去六律六，又减去七星七，又减去八风八，又减去九章九，余数为单数即为男孩，余数为双数即为女孩，万无一失。
The *Bingyuan Lun* (Treatise on the Origins and Manifestations of Diseases) states: A pulse that is deep and solid (Chen Shi) on the left hand indicates a male fetus, while a pulse that is floating and large (Fu Da) on the right hand indicates a female fetus; if both hands present with deep and solid pulses, twins boys will be born. If both hands present with floating and large pulses, twin girls will be born. It further states: Have the pregnant woman walk south, then suddenly call her name; if she turns to the left, it is a boy, and if she turns to the right, it is a girl. It also states: If the husband has a nodule in his left breast, it is a boy; if he has a nodule in his right breast, it is a girl.
The *Qianjin Fang* (Prescriptions Worth a Thousand Gold) states: A floating and large pulse at the Chi position (Cun-Kou pulse location corresponding to the Kidneys/Bladder/Lower Jiao) on the left hand indicates a male fetus, while a deep and fine pulse at the Chi position on the right hand indicates a female fetus.
The *Chan Jing* (Obstetrics Classic) states: The method of determining fetal gender through pulse diagnosis:
For a pregnant woman, at three months gestation, the Chi pulse becomes rapid (Shu). A predominantly large pulse at the left Chi position indicates a male fetus, a predominantly large pulse at the right Chi position indicates a female fetus, and large pulses at both Chi positions indicate two fetuses.
It further states: Regarding the pregnancy pulse, a rapid pulse on the left indicates a male fetus, a rapid pulse on the right indicates a female fetus, and large pulses on both sides indicate two fetuses.
It further states: The method for divining fetal gender:
Legend says: Place Chuan Song (a Shen Sha or divine spirit in Chinese astrology) onto the husband's natal year branch, and observe if it appears on the wife's You Nian (wandering year). Obtaining a Yang Shen indicates a male fetus, and obtaining a Yin Shen indicates a female fetus.
One theory states: If Tian Gang and Tian Hou are placed on the mother's age branch, or if You lands on a Yang Chen (Yang Earthly Branch), or if Gong Cao lands on Yang; or if the Heavenly Stem has Qi (vital energy), or if the Time matches the Day Stem, or if a Yang Shen lands on the Day, it will certainly be a male fetus; if Gong Cao lands on a Yin Chen and there is Qi on the Earthly Branch, it will be a female fetus.
One theory states: Obtaining Qing Long (Azure Dragon) and Tai Shang leads to mostly male children. Obtaining Tian Hou and Tai Yang (Yin) leads to mostly female children.
One theory states: Consistently place Chuan Song onto the woman's natal year branch; if the Wandering Year is under a Yang Shen, it is a male fetus; if under a Yin Shen, it is a female fetus.
One theory states: Wei Ming placed on Si Meng (the four beginning branches: Yin, Shen, Si, Hai) indicates a male fetus; Shen Hou placed on Si Zhong (the four central branches: Zi, Wu, Mao, You) indicates a female fetus.
One theory states: If the mother's Wandering Year lands on Si Meng, it is a male fetus; if it lands on Si Zhong or Ji (ending branches), it is a female fetus.
One theory states: Teng She, Zhu Que, Qing Long, Gou Chen, Xuan Wu, and Bai Hu, when added to the Day and Hour, all indicate male fetuses. Liu He, Tian Guan (Kong Wang/Void), Da Yin, Tian Hou, and Da Shang, when added to the Day and Hour, all indicate female fetuses.
One theory states: Direct application: If the Shen is in a Yang position, it resembles the father; if in a Yin position, it resembles the mother. If prosperous (Wang/Xiang), the child will be beautiful; if imprisoned or resting (Qiu/Xiu), the child will be ugly.
It further states: The method of determining fetal gender based on the mother's age:
At age 13, establishing Shen produces a male; at age 14, establishing Wei produces a female; at age 15, establishing Wu produces a female; at age 16, establishing Si produces a male; at age 17, establishing Chen produces a male; [age 18] establishing Hai produces a male; at age 23, establishing Xu produces a male; at age 24, establishing You produces a male; at age 25, establishing Shen produces a male; at age 26, establishing Wei produces a female; at age 27, establishing Wu produces a male; at age 28, establishing Si produces a male; at age 29, establishing Chen produces a male; at age 30, establishing Mao produces a female; at age 31, establishing Yin produces a male; at age 32, establishing Chou produces a male; at age 33, establishing Zi produces a female; at age 34, establishing Hai produces a male; at age 35, establishing Xu produces a male; at age 36, establishing You produces a male; at age 37, establishing Shen produces a male; at age 38, establishing Wei produces a female; at age 39, establishing Wu produces a female; at age 40, establishing Si produces a male; at age 41, establishing Chen produces a female; at age 42, establishing Mao produces a female; at age 43, establishing Yin produces a male; at age 44, establishing Chou produces a male; at age 45, establishing Zi produces a female; at age 46, establishing Hai produces a male; at age 47, establishing Xu produces a male; at age 48, establishing You produces a female; at age 49, establishing Shen produces a male; at age 50, establishing Wei produces a male.
It further states: To calculate the gender using arithmetic: First, write down the husband's age, then the wife's age, and then the month of conception. For a conception in the first lunar month, count as twelve months. Sum these numbers. Then subtract Tian Yi (1), Di Er (2), Ren San (3), Si Shi (4), Wu Xing (5), Liu Lv (6), Qi Xing (7), Ba Feng (8), and Jiu Zhang (9). If the remainder is odd, it is a male; if even, it is a female. This method is infallible.
