Does being too overweight affect pregnancy for couples

Both spouses with excessive weight may indeed affect the probability of pregnancy, mainly due to factors such as hormonal imbalances, ovulation disorders, and decreased sperm quality. Obesity may interfere with women's normal ovulation function, while reducing male sperm motility and increasing the risk of pregnancy complications. Female obesity can easily lead to endocrine disorders, and abnormal levels of estrogen in the body may inhibit follicular development, resulting in irregular menstruation or anovulation. Excess adipose tissue will secrete more leptin, interfering with the function of the hypothalamic pituitary ovarian axis. Polycystic ovary syndrome is more common in obese women, characterized by hyperandrogenism and insulin resistance, which directly affect fertility. Male obesity is associated with a decrease in testosterone levels, while an increase in scrotal temperature and oxidative stress response can lead to damage to sperm DNA, resulting in a significant decrease in semen parameters such as concentration and vitality. Some mildly overweight couples may still conceive naturally, but potential risks need to be monitored. The degree of obesity is positively correlated with fertility decline, and when the body mass index exceeds a certain range, the success rate of assisted reproductive technology will also decrease. Some individuals with special physical conditions may be less sensitive to the effects of obesity, but this is a rare occurrence. Obesity may also induce complications such as pregnancy diabetes, pre eclampsia, and increase the probability of miscarriage and premature delivery. Couples preparing for pregnancy should improve their fertility conditions through scientific weight loss, and it is recommended to adopt a balanced diet and moderate exercise under professional guidance. Reduce refined carbohydrates intake, increase high-quality protein and dietary fiber, and combine aerobic exercise with strength training every week. Regularly monitor basal body temperature and ovulation test strips, and males can undergo routine semen examination. If natural pregnancy preparation is unsuccessful for more than one year, it is necessary to seek timely evaluation from a reproductive medicine center. Controlling weight within a reasonable range before pregnancy can help improve the success rate of conception and ensure the health of both mother and baby.
