Medical science suggests that weight gain can disturb reproductive hormones, affecting ovulation in women and sperm quality in men. If you are planning for conception, weight gain could be a significant roadblock to fertility. Now, the question arises- What’s the real link between winter weight gain and fertility? Let’s discuss how weight gain may affect fertility and ways to maintain optimal body weight.
How Does Weight Gain Affect Fertility?
Weight gain affects reproductive hormones in both men and women, which reduces the chances of a successful pregnancy. Here’s how weight gain affects fertility.- Disturbed Hormonal Balance: Winter is a season of festive celebrations, which leads to excessive consumption of sweets and causes weight gain. When there’s excess body fat, it increases estrogen in the body, affecting ovulation in women and testosterone production in men. When these hormones become imbalanced, conception becomes harder. Even a 5-10% increase in body weight can affect fertility in both men and women.
- Reduced Sperm Health: Excessive body fat in men may increase scrotal temperature and oxidative stress, which are harmful to overall sperm health. Furthermore, excessive body fat converts testosterone into estrogen, which ultimately leads to lower sperm count, motility (movement), and morphology (shape). If you don’t maintain an optimal body weight, it affects fertility and reduces your chances of a successful conception.
- Increased Risk of PCOS & Insulin Resistance: Weight gain in women may worsen insulin resistance, which increases insulin and androgen (male hormone) and causes polycystic ovary syndrome (PCOS). It’s a common disorder in women which disrupts ovulation, causes irregular periods, and reduces egg quality. Maintaining an optimal body weight is crucial for balancing your insulin and hormone levels and boosting your fertility.
- Increased Risk of Miscarriage & Unsuccessful Implantation: Higher body fat can trigger inflammation, thereby altering the uterine lining and making it difficult for the embryo to attach securely. It leads to miscarriage or failed implantation in IVF cycles. Furthermore, obesity in women can increase the risk of medical complications, including hypertension, gestational diabetes, and preeclampsia.
Tips to Manage Weight & Boost Fertility
Winter tempts us to indulge in sweets and rich festive foods, which can lead to weight gain and affect fertility. Here’s how you can maintain an optimal body weight.Stick to a Nutrition-Rich Diet
Replacing your regular meals with a nutrition-rich diet is crucial to reducing excess fat and maintaining a healthy body weight. Consuming roasted nuts, warm soups, oats, sweet potatoes, and seasonal fruits and vegetables helps boost immunity and support reproductive hormones. These winter superfoods are rich in antioxidants, vitamin C, zinc, and fibre, which keep you full, reduce your calorie intake, and help you lose weight healthily.Tip: Consult your nutritionist before adding these seasonal fruits and vegetables to your diet to avoid digestion-related issues.
Get Adequate Sunlight Exposure
Shorter days and longer nights in winter mean reduced sunlight exposure, leading to lower Vitamin D production. Vitamin D deficiency can lead to low testosterone, hormonal imbalances, irregular ovulation, and mood fluctuations. Furthermore, spend at least 20-30 minutes in early morning sunlight to maximise Vitamin D absorption. If your sunlight exposure is limited, consult your doctor about vitamin D3 supplements.Exercise is a Must
If you want to maintain an optimal body weight and boost fertility, regular movement is key. Performing exercises like running, walking, stretching, or light strength training helps regulate insulin, balance reproductive hormones, and keep your metabolism active, which means less fat deposit. Even 30 minutes of daily activity is enough to keep you in shape and boost your fertility hormones.Note: Consult your doctor before starting any physical activity to rule out any underlying medical conditions.
Prioritise Quality Sleep
Sleep plays a crucial role in regulating your reproductive hormones and maintaining fertility. Inadequate sleep disrupts hormones like leptin and ghrelin, which regulate your hunger and appetite, leading to overeating and weight gain. Get at least 7-8 hours of sound night's sleep to balance your hormones, especially testosterone in men and progesterone and estrogen in women.Tip: Avoid screens before bedtime and maintain a regular sleep-wake routine to manage your sleep schedule.
Winter is a perfect season for festive celebrations and enjoying rich foods. But it can also lead to unexpected weight gain and affect your fertility. By following these recommended tips, you can maintain a healthy weight, boost your fertility, and increase your chances of conceiving naturally.
