Probiotics can boost sperm function

Probiotics have been all over the news recently and many of my patients ask me about them in our visit. Probiotics are live bacteria and yeasts that may be beneficial to our health, especially our gut health. We are learning that our gut health can impact our overall health including health conditions like diabetes and autoimmune conditions. Emerging studies are demonstrating that what we eat can alters our gut health can impact our natural fertility.


A recent study provided the probiotic, Lactobacillus rhamnosus, to obese mice and found that the mice lost weight and had improved sperm function. This could mean that adding more probiotics to your diet, could help you boost your naturally fertility and help you lose weight, too.
I’m cautiously optimistic with this study. Improving obesity and sperm function in mice is not the same as improving sperm function in humans so more studies are needed to prove that this actually works. In the meantime, consider adding probiotics and pre-biotics to your diet. You will probably feel better, but it may help you get pregnant sooner, too.

The hard work is worth it

Changing your habits is HARD– it’s hard to change what you eat, to make time for regular exercise, and to prioritize your well-being. But it’s absolutely worth it!

So many patients with infertility tell me they feel powerless and hopeless.  I want to empower you to believe that there are some things that you can do to boost your fertility. And it starts with taking care of yourself.

Your weight is very important for your health and your fertility. So important that we have discussed it here, here, here, and even here. It’s a recurring topic on the blog because it’s important and it is, unlikely your age, something that you can change.

A study was recently published that the hard work that is needed to lose weight is worth it. Women who consumed fewer calories and started exercising were much more likely to lose weight, ovulate on their own, and get pregnant compared to people who didn’t make these changes.  A combination of fewer calories by reducing fat and refined carbohydrate intake, and increased aerobic exercise is the cornerstone of healthy weight loss.


What you can do

  • Do something, ANYTHING for exercise 30 minutes, 5 days a week.
    • Consider using a fitness tracker or pedometer like FitBit
    • Schedule your workouts when nothing will interrupt your session. Make your fitness a priority.
  • Take a closer look at your diet and what you can cut out easily. Consider an app like MyFitnessPal.
    • Start by eliminating refined carbohydrates found in juices, sodas, and sweets
  • Don’t get discouraged. Any step is a step in the right direction.
  • Talk to your doctor for more information about local support groups and fitness programs in your area.

Dads- pay attention too!

In my fertility clinic, much of the discussion about pre-conception counseling, or what should be done to prepare for a healthy pregnancy, focuses on the female. We discuss a woman’s diet, vitamins, immunization status, supplements, exercise habits and more. New research is suggesting that dad needs to be involved in this health optimization before starting a family.

Epigenetics is a new hot term in science. We all have DNA, which is a roadmap of genes that encode the proteins that are expressed that make our bodies work. To describe it simply, epigenetics is the field that ensures that these genes are expressed at the right time, the right place, and the right amount. My research over the past three years has focused on epigenetics.

I am passionate about learning how our environment impacts our fertility. Epigenetics is an emerging link  to learning about your environment and how it may impact your genetic health: most toxins in our environment are not strong enough to cause DNA damage and mutations, but are able to impact gene expression, and ultimately the health of an individual, by altering epigenetic profiles. Exposure to endocrine disrupting chemicals in our environment, like those commonly found in plastics, induce epigenetic changes in sperm. Worse yet, these changes can be transmitted to future generations.

Recent studies suggest that epigenetic changes may be the key mechanism by which paternal factors such as age and weight contribute to health outcomes in their kids. For example, dads who smoke have children that are more likely to be overweight. Similarly, dads that are obese are more likely to have obese children as a result of epigenetic changes.

Dads- don’t lose hope. There are early indications that some paternal lifestyle-associated effects on sperm can be reverse through exercise, diet, and/or surgical weight loss. In my practice, I like to focus on the couple becoming the healthiest they can be before conceiving. Because ultimately, our goal is similar: we don’t just want to help you get pregnant, we want to help you be a healthy and happy family for generations to come.

Are Low-Calorie Sweeteners Making You Fat?

There is a global obesity epidemic. More than one BILLION adults are projected to be obese by 2025. Obesity is a major risk factor for the development of medical conditions such as diabetes and cardiovascular disease, as well as numerous types of cancers. Obesity, in either male or female partners, is associated with a decrease in the ability to become pregnant. Obese women are not only at an increased risk of having trouble conceiving, they are also at risk of: needing medications to conceive, being less responsive to fertility treatments, losing pregnancies to miscarriage, having children with birth defects, as well as having complications during pregnancy such as high blood pressure and diabetes.


Many people use artificial sweeteners or “diet” drinks as a substitute for whole ingredients with the hope of cutting calories. A recent study suggests that this may be a bad idea. This group followed people for 10+ years and found that people that used low-calorie sweeteners had a higher body mass index (BMI), larger waist circumference, and were more likely to be obese. This paper suggests that using low-calorie sweeteners may not be effective means of weight control, and might even lead to harm.


When I review studies like this, I think it’s important to note that these studies are NOT designed to prove that artificial sweeteners CAUSE obesity; rather, they show an ASSOCIATION at a population level. For me, as a physician and mom, this association is reason enough to be cautious about the use of artificial sweeteners. For others, especially die-hard Diet Coke drinkers, they might want more proof before changing their diet habits.


There is no easy solution for weight loss; diet drinks probably aren’t going to help. If you are overweight or obese, don’t lose hope. Even a modest weight loss (10-15% body weight) can enhance your natural fertility. It will take hard work through diet and lifestyle changes. Avoid sugary snacks and drinks in general. Consider using natural sweeteners like stevia (Dr. Greene’s favorite!) or honey (my favorite!) instead of artificial ingredients. Your selection in which sweetener you use, is likely going to depend on what is most important to you including considerations like why you are using a sweetener, why you are looking for artificial sweeteners (cutting calories), and taste. Please be an informed consumer and make sure that you know why you are making the choices that you make. Taking care of yourselves will help prepare you for a healthy pregnancy and prepare you to be healthy parents.



The Newly Discovered Fat Hormones*

*The following is an excerpt from my book PERFECT HORMONE BALANCE FOR FERTILITY[u1] . If you’re working to lose weight or wondering if/how this may improve your chance for conception then read on…

Fat cells are not passive calorie warehouses, but rather mini endocrine factories that produce at least 20 different hormones, collectively called adipokines. These hormones direct your metabolism and help your brain keep track of your energy stores to control appetite and budget how your body uses this energy. Adipokines also help your brain determine if you have enough fat stores to sustain pregnancy. Your brain also takes into account how effectively you can share your energy with your baby—if you’re insulin-resistant, your body doesn’t channel energy to the fetus as effectively. As you modify your diet, fat cells adjust their adipokine secretions to bring them more into balance, improving your fertility profile. Here are some of the key adipokines and how they affect your weight.

  • Leptin tracks how many calories you have stored as fat—the more fat you have, the more leptin in your blood. When leptin levels are high, your brain suppresses your appetite and revs your metabolism to help you burn calories. But when leptin is chronically elevated, at it is in obesity, your brain tunes out the appetite-suppressing effect. Low leptin, on the other hand, signals low fat stores—a red flag that your brain should halt ovulation.
  • Adiponectin helps your body use fat as fuel. As you gain weight, though, you produce less adiponectin, and low levels are associated with fertility problems. As you lose weight, fat cells release more adiponectin, increasing your chance of conception.
  • Resistin is released by fat cells, resisting insulin’s ability to help store glucose. If you’re overweight, resistin rises, leading to insulin resistance and reduced fertility.

The Obesity Dilemma

Over the last 25 years, infertility rates have risen in proportion to the rise in obesity in men and women in their reproductive years.  One analysis determined that at least 10 percent of today’s fertilty problems are related to overeating. The good news for obese people is that losing 10 percent of your body weight will improve your chance of conception (if you’re overweight, not obese, you’ll see the benefits after losing only 5 percent of your body weight). So create short-term goals on your path to hormone balance and don’t focus on attaining your ideal body weight.
