Small follicle ovulation is an abnormal ovulation pattern, which is often clinically manifested as ovulation occurs when the most dominant follicle is immature, and is classified as a type of ovulation disorder or follicular dysplasia syndrome. Chinese medicine believes that the spleen and stomach are "the source of qi and blood biochemistry, and the foundation of the day after tomorrow". The spleen and stomach take the function of transporting and transforming as the core, combining the innate essence from the two aspects of transporting and transforming water and grain, and transporting and transforming water and dampness, to provide the necessary subtle substances for the development of follicles and endometrium. The theory of the spleen and stomach is applied throughout the whole stage of the treatment of ovulatory infertility with small follicles, focusing on the influence of acquired factors on the function of the hypothalamus, regulating the spleen and stomach so that the whole body qi movement is normal, the function of the hypothalamic axis is normal, and the qi and blood of body fluids On this basis, focus on tonifying kidney qi, regulating yin and yang, so as to achieve balance, uterine storage and diarrhea, improve endometrial receptivity, regulate the entire internal environment of the body, and promote "shen qi-tiangui" -Chongren-uterus" reproductive axis (ie "hypothalamus-pituitary-ovarian axis") functions normally, improves the body's endocrine, promotes the development and maturation of follicles and helps to conceive, which has positive clinical significance.
