Obesity can significantly affect fertility. Excess body fat disrupts hormone levels, which can interfere with ovulation in women and reduce sperm quality in men. In fact, even modest weight loss can improve fertility outcomes. Therefore, talk to your healthcare provider if you’re trying to conceive and struggling with weight.
Obesity is a growing concern worldwide and has a major impact on reproductive health. In women, excess fat tissue alters estrogen levels, often leading to no ovulation and irregular menstrual cycles. Additionally, conditions such as PCOS (polycystic ovary syndrome), which are often associated with obesity, further impair fertility.
On the other hand, in men, obesity is linked to lower testosterone levels and increased estrogen, both of which can negatively impact sperm count, motility, and morphology. Moreover, increased scrotal fat may also raise testicular temperature, reducing sperm production.
Fortunately, research shows that even a 5-10% weight loss can significantly improve fertility markers in both sexes. Thus, improved diet, physical activity, and behavioral changes are key first steps. For some, bariatric surgery may be considered.
If you’re planning a pregnancy and have concerns about weight, it’s important to consult with a fertility specialist or OB/GYN to develop a personalized approach.
