Couples newly entering their childbearing years should particularly heed this advice, practicing self-respect and restraint. Avoid excessive indulgence, as treating diseases after they develop can lead to significant complications—even lifelong infertility—resulting in profound regret. 1. Optimal Age for Childbearing The peak fertility window for both men and women is between 25 and 30 years old. At this stage, physiological maturity is achieved, energy levels are at their peak, and the body is best suited for pregnancy.Since a child's intelligence is largely inherited from the father, fathers over 30—when intellectual maturity peaks—are more likely to father intelligent children. Thus, the optimal male fertility window can extend to ages 30–40. However, as women age, ovarian function declines. They also face increased exposure to harmful substances like radiation, environmental pollutants, and toxins, raising the risk of genetic mutations. This heightens the likelihood of miscarriage and birth defects.2. Selecting a Suitable Partner (1) Prohibit marriage and childbearing between close relatives to reduce the incidence of genetic diseases. "Close relatives" generally refer to: - First-degree blood relatives: parents and children. - Second-degree blood relatives: grandparents and grandchildren, or siblings. - Third-degree blood relatives: uncles/aunts and nieces/nephews. - Fourth-degree blood relatives: cousins.(2) Conduct thorough premarital examinations to detect congenital reproductive abnormalities affecting fertility and eugenics, as well as conditions like ABO blood type incompatibility causing hemolysis. This allows both partners to prepare psychologically for treatment and, if necessary, consider assisted reproductive technologies like artificial insemination.3. Enhance physical fitness. Both partners must nourish their essence and blood to produce high-quality sperm and eggs, providing the raw materials for fertilization. A healthy mother with abundant qi and blood can sustain the fetus and prevent miscarriage. 4. Timing conception correctly. Increase sexual intercourse frequency within two days before and after ovulation during each menstrual cycle to boost conception chances.

Excessive frequency may decrease sperm count or impair sperm development, also affecting fertility. (2) Avoid intercourse after alcohol consumption. Alcohol adversely affects reproductive cells, diminishing fertilized egg quality.(3) Engaging in intercourse during menstruation, immediately after childbirth, or when residual blood from an abortion procedure has not fully cleared can lead to genital inflammation, endometriosis, and the development of anti-sperm antibodies—all contributing to infertility. Experts advise: Avoid intercourse three days before and after menstruation. After vaginal delivery, resume intercourse only after menstruation resumes or at least two months later; after cesarean section, wait three months. Abstain from sexual activity for one month following an abortion procedure.(4) Honeymoons are unfavorable for conception. Irregular routines, physical exhaustion, and frequent sexual activity during this period, coupled with inadequate hygiene conditions for genital organs, increase the risk of urinary tract and genital infections in women. Heavy smoking and alcohol consumption may impair sperm and fertilized egg quality. These adverse factors can stimulate and damage the embryo, leading to miscarriage, premature birth, or stillbirth.(5) Sexual activity should be strictly avoided during the first trimester (first three months) and late pregnancy, especially for those with a history of miscarriage, to prevent miscarriage or premature birth. 6. Regulating Emotional Well-being First, eliminate aversion, fear, or anxiety toward sexual activity. Only when both partners achieve harmonious qi and blood flow and maintain a joyful spirit can they possess the vitality to conceive the fruit of their love at the optimal time.Excessive mental tension, intense desire for a child, or overwork can all lead to "psychogenic infertility." Women are naturally more emotionally sensitive than men. If they fail to adopt a healthy, positive outlook on life and manage stress from work and living environments, accumulated worries may eventually manifest as illness. Commonly seen is liver qi stagnation, which disrupts the normal flow of qi and blood, interferes with endocrine regulation, and leads to menstrual irregularities or tumors. This can impair conception and even cause miscarriage.7. Dietary Adjustments (1) Excessive consumption of raw, cold, rich, or greasy foods during menstruation can damage the spleen and stomach, causing stagnation in the meridians and impaired blood flow, resulting in dysmenorrhea or metrorrhagia. Conversely, sour, spicy, pungent, or aromatic foods can boost yang energy while depleting yin, forcing blood to flow erratically and causing excessive menstrual bleeding. (2) Dieting for weight loss may lead to low levels of sex hormones, affecting ovulation and causing amenorrhea or infertility.(3) Tobacco and alcohol damage reproductive cells, with spirits posing greater harm. Avoid exposure for at least six months before attempting conception. (4) Exercise caution with certain foods and both Chinese and Western medications during early pregnancy (as previously noted).

Severe cervical inflammation in the patient or inadequate sterilization during the procedure may introduce bacteria into the uterine cavity, causing salpingitis and tubal blockage that impedes sperm-egg encounter and fertilization. Excessive suction or curettage can damage the cervical canal and endometrium, leading to cervical adhesions and narrowing that obstruct sperm entry into the uterine cavity or hinder embryo implantation and development.Repeated abortions damage the basal layer of the endometrium, preventing its regeneration and causing post-operative amenorrhea.Since the procedure is not performed under direct visualization, the doctor must rely on tactile sensation during manipulation. This increases the risk of complications such as incomplete evacuation, uterine hemorrhage, endometritis, uterine perforation, and endometriosis. Additionally, the abrupt drop in hormone levels post-procedure can disrupt the hypothalamic-pituitary-gonadal axis, leading to menstrual irregularities. All these factors may contribute to infertility or recurrent miscarriage.9. Actively treat underlying conditions such as chronic malnutrition, chronic poisoning, severe heart disease, diabetes; male erectile dysfunction or premature ejaculation; and female conditions like hypothyroidism, hyperthyroidism, or adrenal dysfunction. 10. Avoid exposure to radiation, toxins, or harmful environments during early pregnancy. 11. Correct sexual positions primarily address infertility caused by retroverted uterus.The chest-knee position is recommended: the woman rests her chest on a pillow, bends her knees, kneels on the mattress with legs apart, while the man also bends his knees and inserts his penis from behind between her legs. This positions the cervical opening to be immersed in the deposited semen, facilitating conception.
