What are the harms of obesity to reproduction?
1 The impact of obesity on pregnancy itself: Obesity can easily cause endocrine disorders, affect ovulation, and thus affect pregnancy.
60% to 80% of patients with polycystic ovary syndrome (PCOS) are overweight or obese, especially the accumulation of abdominal fat. Insulin sensitivity decreases, secretion decreases, and is associated with obesity. Obese PCOS patients need to lose weight first when they are pregnant. A 7% weight loss can increase insulin sensitivity by 57%. A 5% weight loss can change or reduce menstrual disorders, hirsutism, acne and other symptoms and alleviate psychological stress; reducing the weight to a normal range can improve insulin resistance, increase natural ovulation rate and improve Response to ovulation-inducing treatment improves live birth rates in PCOS patients; maintaining normal weight can prevent the long-term development of adverse consequences of PCOS, such as metabolic syndrome such as diabetes, hypertension, hyperlipidemia, and cardiovascular disease.
2 The impact of obesity on the IVF cycle:
In patients during the IVF cycle, as the weight As the index (BMI) increases, the embryo implantation rate, clinical pregnancy rate, and live birth rate of in vitro fertilization-embryo transfer (IVF-ET) are significantly reduced, while the miscarriage rate is significantly increased. Therefore, clinicians generally recommend that BMI>27kg/m² patients first control their weight before entering cycle treatment.
Affected by excess subcutaneous fat, obese patients may have difficulty in vaginal ultrasound examination during the IVF cycle, and the follicles are not clearly displayed; the ovaries are located far away from the vaginal ultrasound probe, making the egg retrieval operation more difficult; and it is difficult to expose the cervix. , increasing the difficulty of embryo transfer surgery.

The impact of obesity on pregnancy and delivery:
Obesity increases complications during pregnancy, such as gestational diabetes, gestational hypertension, preeclampsia, etc., and also increases cesarean section , fetal distress, neonatal asphyxia, macrosomia, and the incidence of postpartum hemorrhage. Obese women are prone to prolonged labor and even dystocia during delivery. Even if they choose cesarean section, the incision is not easy to heal, and the chances of fat liquefaction and incision infection after suturing are increased.
4 The impact of obesity on the next generation:
Latest published research in the United States: Children with non-obese parents Children whose mothers are obese are 1.67 times more likely to fail the fine motor test, children whose fathers are obese are 1.75 times more likely to fail the social ability test, and children whose parents are both obese (BMI ≥35) also fail the problem-solving ability test. A 10-year follow-up study by the University of Pittsburgh found that the mother\’s pre-pregnancy MBI is negatively correlated with the child\’s IQ and the child\’s executive ability.
5 Impact of male obesity on fertility:
Obesity can affect male sex hormones, reduce sperm count, increase oxidative sperm DNA damage and change the epigenetic status of sperm. Changes in sperm function caused by obesity can also affect embryonic development, increase fetal miscarriage rates and reduce birth survival rates.
How to judge whether your weight is overweight?
1 Body mass index (BMI):
BMI=weight (kg)/height (m)².
2 Waist-to-hip ratio:
The waist-to-hip ratio is the ratio of waist circumference to hip circumference, which reflects the human abdomen An important indicator of obesity. A value >0.9 for men and >0.85 for women indicates central obesity.
3 Body fat rate:
Body fat rate is the percentage of body fat in body weight.
The calculation formula is: body fat percentage = body fat (kg)/body weight (kg)×100%
How to obtain diagnosis and treatment for weight management?
1 Female clinic, male clinic:
Clinic doctors determine whether the cause of infertility and the cause of IVF failure are related to obesity Related, provide guidance on reasonable and healthy weight management methods.
2 Nutritional clinic:
Nutritional doctors visit the reproductive center clinic all day every Friday to provide guidance on reasonable diet for pregnancy.
30th floor clinic service desk:
Perform \”Body Composition Analysis\” examination and analyze body fat percentage (currently this project is free for patients in our center)
Control your weight and take action! A healthy self is the prerequisite for having a healthy and smart baby!
