Obesity is emerging as a significant obstacle to the success of in-vitro fertilization (IVF) treatments in Malaysia, with both male and female obesity linked to reduced fertility outcomes. Fertility experts are increasingly concerned about the growing obesity epidemic, urging couples trying to conceive (TTC) to prioritize their health before pursuing fertility treatments.
Dr. Sharifah Najwa Syed Amin Husaini, a Consultant Obstetrician and Gynaecologist at Kensington Green Specialist Centre in Johor, underscores that obesity is no longer just a lifestyle issue, but a serious chronic disease with far-reaching health implications. “Obesity is an epidemic that not only impairs fertility but also increases the risk of heart disease, diabetes, and cancer,” Dr. Sharifah Najwa said, highlighting the broader public health challenge Malaysia faces as Southeast Asia’s most obese nation.
Obesity affects fertility by disrupting the body’s hormonal balance. In women, it leads to elevated levels of leptin—a hormone produced by fat cells—that interferes with the regulation of reproductive hormones. Dr. Sharifah Najwa explained that obesity in women is often linked to conditions like polycystic ovary syndrome (PCOS), a major contributor to fertility issues.
For couples undergoing IVF, the impact of obesity is even more pronounced. Dr. Sharifah Najwa points out that women with obesity often need higher doses of fertility drugs and may not respond effectively to ovarian stimulation. This can result in fewer eggs being harvested, and a reduced likelihood of successful embryo implantation. For men, obesity also poses fertility challenges, including diminished sperm motility and concentration, as well as potential DNA damage in sperm, all of which contribute to decreased fertility.
As IVF treatments can be expensive, Dr. Sharifah Najwa emphasizes that many couples in Malaysia may require multiple cycles to achieve a successful pregnancy. Given this, she advises couples to begin their fertility journey by adopting healthier lifestyles. She recommends starting with weight management through better diet and regular exercise before resorting to medical treatments like anti-obesity medications or bariatric surgery.
“Managing your weight is critical to improving your chances of conception,” said Dr. Sharifah Najwa. “A diet rich in protein and fiber, combined with consistent physical activity, can help couples achieve a healthier weight and enhance fertility outcomes before considering IVF.”
Beyond fertility concerns, obesity during pregnancy poses additional risks, including gestational diabetes, high blood pressure, and even miscarriage. These complications not only endanger the health of the mother but can also affect the outcome of future pregnancies. Children born to obese parents are more likely to develop chronic conditions such as heart disease in adulthood, compounding the long-term impact of obesity.
As Malaysia grapples with rising obesity rates, Dr. Sharifah Najwa stresses the importance of couples fully committing to their fertility journey, both in terms of physical health and mental preparation. By addressing the root cause of obesity, couples can improve their chances of successful IVF treatment and safeguard their overall health and well-being.
