The Relationship between Obesity and Infertility

British researchers surveyed 318 women undergoing artificial insemination, about half of whom were overweight or obese. Finally, after considering other factors such as age, medical history, and smoking, the researchers found that these women were twice as likely to have abortions as normal women.

According to Forbes, the latest data from the Centers for Disease Control and Prevention (CDCP) show that nearly four out of every ten adults in the United States can be classified as obese. Since the beginning of this century, the obesity rate of American adults has steadily increased, from 30.5% in 1999/2000 to 39.6% in 2015/16, a record high. Now, in the past three years, this data is still growing year by year, showing only an increasing form.

The relationship between obesity and infertility：

1. Obesity can lead to abnormal follicular development and ovulation

Obesity has a significant impact on women's menstruation. The accumulation of abdominal fat can lead to insulin resistance, endocrine disorders, abnormal ovulation, and pregnancy.

2. Vulnerability to gynecological diseases

Nowadays, polycystic ovary syndrome (PCOS) is a common disease in women due to endocrine and metabolic disorders. Most women with PCOS are obese. The typical clinical manifestations of PCOS are irregular menstruation, amenorrhea, and infertility.

Because obese women generally have more fat in their bodies, it can also lead to an increase in estrone content, and estrone is considered to be a pathogenic factor for endometritis. Inflammation in the uterus can easily lead to abortion. Therefore, patients can timely take Fuyan pills with anti-bacterial, anti-inflammatory, heat-clearing, and detoxifying effects to treat, in order to avoid adverse effects on the fetus.

3. Obesity affects implantation

Obesity reduces endometrial receptivity. The slow blood supply of uterine spiral artery affects the implantation of fertilized eggs. The more obese woman is, the worse implantation ability of fertilized eggs are.

4. Obesity Affects Oocyte Development

If a woman is too obese, the pancreas secretes insulin will increase, but too much insulin in the human body will affect fertility, especially in women. It can cause poor quality of eggs, ovarian dysfunction, and so on. The quality of eggs in test-tube babies has great quality requirements, so the poor quality of eggs affects the combination with sperm, thus affecting the quality of embryos.

So how to lose weight correctly before the test-tube baby is carried out to improve the success rate of pregnancy?

1. Improving diet

Keep a balanced diet with milk, fruits and vegetables, nuts, and skinned grains. Supplementation of trace elements such as iodine, vitamin D, folic acid, and B vitamins plays a vital role in improving pregnancy rate.

2. Adjusting Mentality

Psychological stress is also a significant cause of obesity. Overeating, irregular sleep, tension, and anxiety caused by mental stress may lead to further weight gain.

3. Making Weight Loss Plan

Through running, walking, cycling, and other aerobic fitness exercises, to achieve the goal of weight loss.

4. Lose weight with your partner together

If both husband and wife are obese, they need to lose weight together. Obesity affects not only egg quality but also male sperm. In order to produce the best embryos, couples need to lose weight together.

Overall, obesity has a negative impact on fertility and IVF. Therefore, if there is obesity in couples who want to get pregnant naturally or carry out IVF, weight loss is the key factor, and also has great benefits for their long-term health.
