Traditional Chinese Medicine treats the menstrual cycle as four distinct phases, each with its own yin-yang balance and its own fertility role. Chinese medical writing has worked with this four-phase model since at least 1237, when Chen Ziming compiled the first systematic Chinese gynecology text, 妇人大全良方 Fùrén Dàquán Liángfāng, the Complete Effective Prescriptions for Diseases of Women.
The Chinese fertility calendar in TCM terms is this phase map, not the boy-or-girl prediction chart. The chart that predicts a baby’s sex is a separate folk tool, covered in our Chinese pregnancy calendar guide. This page explains the four cycle phases, the acupuncture points TCM clinicians use at each phase, the foods Chinese medicine recommends and avoids, what modern research says about acupuncture and IVF outcomes, and provides a phase mapper that takes a last-period date and cycle length and returns the current TCM phase with its associated guidance.
The TCM Four-Phase Menstrual Cycle
TCM gynecology divides every 28-day cycle into four functional phases. Each phase represents a shift in the balance of yin and yang and in the dominant organ system. The reference texts are 黄帝内经 Huángdì Nèijīng, the Yellow Emperor’s Inner Classic compiled around 200 BCE, for the foundational theory, and 妇人大全良方 Fùrén Dàquán Liángfāng for the gynecological elaboration. Modern TCM clinics still use the same framework, mapped onto Western cycle days.
Menstrual phase, 经期 jīngqī, days 1 to 5. Qi and Blood move outward as the endometrium sheds. The TCM goal is full, unobstructed shedding: retained lining is read as Blood stasis 血瘀 xuèyū, a pattern that disrupts the next cycle. Practitioners avoid strong tonic herbs in this phase, since the body is in a discharging mode. Acupuncture, when used, targets free-flow points such as SP6 三阴交.
Follicular phase, 卵泡期 luǎnpāoqī, days 6 to 13. Yin grows. Blood and essence are replenished, the endometrium rebuilds, and a dominant follicle matures. In Western terms, FSH rises and the egg ripens. The TCM aim is to nourish both the lining, which is Blood, and the egg, which is Kidney essence 肾精 shènjīng. Yin-tonifying herbs and blood-building foods belong to this phase.
Ovulation phase, 排卵期 páiluǎnqī, around day 14. Yin reaches its peak and converts to Yang. The switch needs free flow of Qi. Cervical mucus turns stretchy and abundant, basal body temperature shifts upward by about 0.3 to 0.5 degrees Celsius the morning after release, and Western clinicians track the LH surge with urine tests. TCM treatment in this phase moves Qi and supports the Yin-to-Yang transition rather than tonifying.
Luteal phase, 黄体期 huángtǐqī, days 15 to 28. Yang phase. The corpus luteum produces progesterone, the womb warms, and the body either prepares for implantation or begins the next menstrual reset. TCM treatment in this phase tonifies Kidney Yang and warms the womb. Blood-moving herbs are stopped immediately if conception is suspected, because moving Blood at that point is read as a miscarriage risk in classical texts.
Acupuncture Points Traditionally Used to Support Fertility
TCM gynecology consistently names five acupoints across classical and modern sources for menstrual regulation and fertility support. Locations are given in cun, a TCM unit of measurement scaled to the patient’s body where one cun equals the width of the thumb at the knuckle.
- SP6 三阴交 Sānyīnjiāo, Three Yin Crossing. Three cun above the tip of the inner ankle bone, along the posterior border of the tibia. The convergence point of the Spleen, Liver, and Kidney meridians, hence the name. Used for menstrual irregularity, painful periods, and supporting follicular development. Avoided during pregnancy because it can stimulate uterine contraction.
- CV4 关元 Guānyuán, Gate of Origin. Three cun below the navel on the midline. Tonifies Yuan Qi 原气 yuánqì, the original Qi inherited from the parents, and warms Kidney Yang. The classical point for low libido, cold womb, and fatigue-pattern infertility.
- CV3 中极 Zhōngjí, Middle Pole. Four cun below the navel on the midline, one cun below CV4. The front-mu collecting point of the Bladder channel and a regional point for uterine function. Common in modern acupuncture-IVF protocols for endometrial preparation.
- EX-CA1 子宫 Zǐgōng, Uterus Point. Three cun lateral to CV3, four cun below the navel and three cun to each side. A non-meridian “extra” point dedicated to uterine function in both menstrual and obstetric contexts. Used bilaterally.
- KI3 太溪 Tàixī, Great Ravine. In the depression between the tip of the inner ankle bone and the Achilles tendon. The Kidney source point. Used for Kidney-yin deficiency patterns including reduced ovarian reserve and short luteal phase per modern TCM gynecology.
Self-massage at home with steady thumb pressure for one to two minutes per point is the lay equivalent of clinical acupuncture. Heat applied to CV4 with a moxa stick or warm compress is a common at-home addition during the luteal phase.
Phase-by-Phase Dietary Recommendations from TCM
TCM nutrition for fertility follows one rule above all others: the womb is warm or it is not receptive. Cold and raw foods, 生冷食物 shēnglěng shíwù, are the main category restricted across the entire cycle in classical gynecology. Iced drinks, raw salads, sashimi, watermelon, and ice cream all fall under this category. Modern practitioners often recommend cutting them out for three to six months before active conception attempts.
Menstrual phase foods. Warming, mildly Blood-moving foods: ginger 姜 jiāng tea, brown sugar with red dates 红枣 hóngzǎo, and small portions of lamb soup 羊肉汤 yángròutāng in cold climates. Cold drinks are restricted. Iron-rich foods support Blood replacement: liver, spinach, beef, and black sesame 黑芝麻 hēizhīma.
Follicular phase foods. Yin and Blood building: black beans 黑豆 hēidòu prepared as soup or congee, walnuts 核桃 hétáo, goji berries 枸杞 gǒuqǐ in steeped water or porridge, eggs, and oily fish. Black bean soup is a traditional follicular-phase recipe in southern Chinese kitchens.
Ovulation phase foods. Qi-moving, light foods: spring onion, chives, fresh greens cooked rather than raw, and small amounts of vinegar to support Liver-Qi flow. Heavy tonics are paused.
Luteal phase foods. Warming, Yang-tonifying foods: cinnamon 桂皮 guìpí, walnuts, chestnuts, lamb, chicken broth simmered with ginger and goji. Cold foods are most strictly avoided in this phase because the womb is in its warming mode.
What Modern Research Says About Acupuncture and Fertility Outcomes
Acupuncture for fertility has been studied in randomized trials for over two decades. A 2019 systematic review and meta-analysis published in BMC Complementary Medicine and Therapies by Xie and colleagues pooled 27 trials with 6,116 participants undergoing in vitro fertilization. The pooled clinical pregnancy rate in acupuncture groups was significantly higher than controls, with a relative risk of 1.21 and a 95 percent confidence interval of 1.07 to 1.38. The pooled live birth rate did not reach significance across all studies.
The same review found a stronger effect in a specific subgroup: women who had failed at least one previous IVF cycle. In that group the relative risk for clinical pregnancy reached 1.60 and for live birth 1.42. The authors framed the findings as suggestive of benefit in repeat-IVF cases while noting that the underlying trials varied widely in acupuncture protocol, timing, and methodology.
The honest reading: acupuncture is supported by moderate-quality evidence for IVF patients with a history of failed cycles. For women conceiving without IVF, the evidence base is thinner and consists mostly of smaller observational studies. TCM herbal medicine in pregnancy is held to a stricter standard, because many herbs that move Blood are contraindicated once implantation has occurred.

Chinese Fertility Herbs at a Glance
TCM herbal fertility support runs on combinations, not single ingredients. The classical formulas are phase-specific and pattern-specific: a follicular-phase Yin-and-Blood building formula like 四物汤 Sìwùtāng (Four Substances Decoction) differs from a luteal-phase Yang-tonifying formula like 右归丸 Yòuguīwán (Restoring the Right Kidney Pill).
Common single herbs in fertility formulas include 当归 dāngguī (Angelica sinensis) for Blood, 熟地黄 shúdìhuáng (prepared Rehmannia root) for Yin and essence, 黄芪 huángqí (Astragalus) for Qi, and 菟丝子 tùsīzǐ (Cuscuta seed) for Kidney essence. Most are dosed in formula combinations rather than alone, with adjustments for the patient’s specific pattern.
For the full herb-by-herb breakdown including dosage ranges, classical formulas, contraindications, and which herbs to stop once pregnancy is suspected, see our companion article on Chinese fertility herbs. Herbal medicine should be supervised by a licensed Chinese medicine practitioner because several common fertility herbs interact with anticoagulants, hormonal medications, and pregnancy itself.
Where the Chinese Fertility Calendar Fits With Other Calendars
Chinese fertility planning uses three distinct calendar tools that often get confused in English-language sources. The TCM cycle calendar described on this page tracks the four monthly phases for conception timing and treatment selection. The Chinese pregnancy calendar is the gender-prediction chart based on lunar age and lunar conception month, a folk tool with accuracy near 50 percent in peer-reviewed studies. The Chinese conception calendar covers cultural and astrological timing of conception, including auspicious dates from the Chinese lunar calendar and zodiac considerations from the twelve Chinese zodiac signs.
A couple using TCM fertility support typically combines all three in practice: the cycle calendar for daily food and acupuncture choices, the lunar calendar for cultural date selection, and the zodiac as context for the birth year their child will fall into.
Frequently Asked Questions
How accurate is TCM cycle-phase tracking compared with ovulation kits?
TCM phase tracking and Western ovulation tracking measure different things and complement each other. LH ovulation kits detect the urinary luteinizing hormone surge 24 to 36 hours before ovulation, with high accuracy on the timing question. TCM phase tracking categorizes the cycle by yin-yang balance to guide diet, herbs, and acupuncture choices. Most modern TCM clinics use both: kits or basal body temperature for ovulation confirmation, phase theory for treatment selection.
Can I do TCM fertility acupuncture during IVF stimulation?
Most acupuncture trials reviewed in the 2019 meta-analysis administered treatment around embryo transfer, with some protocols also covering the stimulation phase. Coordination with the IVF clinic is the standard practice, since acupuncture and certain herbs can interact with controlled ovarian stimulation. Many fertility centers in major cities now have an in-house or partnered acupuncturist for this reason.
Are there cycle-phase foods I should avoid year-round?
Iced drinks, raw cold foods, and excessively spicy or greasy foods are restricted across all phases in classical TCM gynecology. The reasoning differs from Western nutritional advice: the restriction is based on the food’s thermal nature in TCM, not its caloric or macro content. Watermelon and cucumber, for example, are nutritionally neutral in Western terms but classed as Cold in TCM and limited during the luteal and menstrual phases.
How long should TCM fertility treatment continue before assessing results?
Three full menstrual cycles is the minimum assessment window in classical practice, since one full follicular development takes about 100 days. Six months is the more common protocol for couples without diagnosed infertility. Older Chinese medical texts including 妇人大全良方 describe extended courses of three to nine months for treating subfertility patterns.
Is the four-phase cycle model used outside China?
Yes. The phase model has been adopted by Korean, Japanese, and Vietnamese traditional medicine traditions, with regional variations in herb selection and acupoint preferences. Korean Saam acupuncture, for example, uses a different point-selection logic but applies it to the same four-phase cycle framework. Western integrative medicine clinics increasingly use the same phase model when treating fertility with combined modalities.
