Coffee, carrots, roast mutton, six major foods are the culprits of infertility.

1. Coffee researchers at the National Institute of Environmental Health Sciences in the United States studied 104 women who wanted to become pregnant and concluded that coffee had a direct effect on pregnancy. Among these women, those who drank more than one cup of coffee a day were only half as likely to become pregnant as those who did not drink the drink. As a result, they suggest that women should drink less coffee if they plan to get pregnant. It should be noted that coffee, carrots, sunflower seeds and other nutrients are essential to the human body, this article only limits the amount of food, while roast beef and mutton, wool cottonseed oil should be included in the scope of fasting.

2. Carrots are rich in carotene, a variety of vitamins and other nutrients beneficial to the human body. Gynaecologists at Rottgis Medical College in New Jersey have found that women who eat too many carrots eat large amounts of carotene that can cause amenorrhea and inhibit normal ovulation. Therefore, women who want to give birth should not eat more carrots.

3. The protein from sunflower seeds to sunflower seeds contains anti-testicular components, which can cause testicular atrophy and affect normal reproductive function, so young people of childbearing age should not eat too much.

4. Roast beef and mutton eating roast beef and mutton is a habit of residents in Inner Mongolia, Xinjiang and other places. It has been found that the children born to a small number of women who love roast mutton are mentally retarded, paralyzed or deformed. After investigation and modern medical research, these women and their deformed children are the victims of Toxoplasma gondii infection. People can often be infected when they come into contact with livestock and poultry infected with toxoplasmosis and eat the undercooked meat of these animals.

5, wool cottonseed oil long-term consumption of wool cottonseed oil, can make people suffer from sun disease, the symptoms are attack after sunburn, body weakness or less sweat skin burning, flushing, shortness of breath, dizziness, limb numbness, loss of appetite. A more serious effect is the damage to the reproductive system. The experimental study showed that after eating the diet containing cottonseed oil for about 4 months, the testis decreased significantly, the sperm cells significantly decreased or even disappeared, the uterus shrank, the endometrium and glands atrophied, the ovary atrophied slightly and the renal parenchyma cells showed slight edema. Adult men take gossypol, an extract of wool cottonseed oil, 60-70 mg a day for 40 days, killing all sperm in a short period of time and gradually disappearing from semen, while women can cause amenorrhea or uterine atrophy. Therefore, young people of childbearing age should not be eaten for a long time.

6. Alcohol scientific research has proved that the main component of alcohol is ethanol, which can increase the concentration of catecholamine in the body, vasospasm, testicular hypoplasia, or even testicular atrophy, and the spermatogenic function will change structurally. insufficient secretion of testosterone and other male hormones will lead to feminization such as thinning of voice and enlargement of breasts. Such people are prone to male infertility, and even if they give birth, the next generation is more likely to have deformities. Women can cause irregular menstruation, amenorrhea, egg production variation, no libido or stop ovulation and so on.
