Exercise and how it affects pregnancy rates

We all know that staying physically active is beneficial to our overall health and wellbeing. But did you know that the right amount of exercise can also improve your chances of conceiving? Here’s why.

Firstly, regular exercise is known to help optimise the reproductive system. It does this by stimulating the endocrine glands, which releases hormones that help your eggs to grow. Secondly, exercise can enhance your metabolism and circulation, which in turn optimises your egg production.

Thirdly, exercise can help you manage or achieve an ideal body weight. Since being overweight or obese can impair fertility in both men and women, weight management is widely known and used to prevent and treat infertility. And lastly, regular workouts also help to relieve stress, which in itself can inhibit fertility.

While regular moderate exercise can have positive effects on fertility and conception, the opposite is true for vigorous exercise.  According to a 2009 study in Human Reproduction, and a Harvard study of elite athletes, vigorous exercise is linked to reduced fertility and pregnancy rates. Therefore, when it comes to exercise and fertility, it is possible to have too much of a good thing.

While there are no guidelines for women to follow when it comes to workout intensity for fertility, there is a way to strike a balance. Studies have shown that women who exercised moderately for at least 30 minutes a day can reduce their risk of infertility due to ovulation disorders. Evidence also suggests that moderate regular exercise can positively influence assisted reproductive technology (ART) outcomes. But what is the right amount of exercise?

If you’re already at your ideal weight, it is safe to stick to your regular routine, but keep it to half an hour maximum per day. Studies had shown that vigorous aerobic exercise of more than 4 hours per week reduces the chance of pregnancy in women going through IVF. If your cycle is still irregular and you haven’t conceived after a few months, you might want to cut back on the intensity of your workouts. However, if you’re underweight, focus on gaining weight and increasing your body fat to the recommended amount of over 12%. If you exercise regularly, cut back on the frequency and opt for a less vigorous routine.

Meanwhile, if you’re overweight, work on cutting down on your calories with healthy eating. You can also increase your exercise routine gradually to achieve your ideal weight. Lastly, if you’re undergoing fertility treatments, it is best to avoid high-impact exercises, as they can be detrimental to your ovaries, which have been enlarged by fertility drugs.

Still have doubts on where to begin? Before you step up your exercise routine, start by speaking to your doctor. If you’ve been having trouble conceiving, your doctor will need to assess your condition first. This includes your age, cycles, ovulatory status, the condition of your uterus and tubes, as well as your partner’s sperm. Once certain conditions have been identified or ruled out, your doctor will be able to advise you on whether the underlying cause may be too little or too much exercise.
