Did you know that one-in-eight couples in the United States has trouble getting pregnant or sustaining a pregnancy and one third of all infertility cases are solely related to male reproductive issues?

When it comes to fertility, I often see women blaming their own bodies before they look into the health of their partner’s sperm. It doesn’t matter if your partner is an Olympic athlete or if he drives a really fast car; sperm health, much like egg health, is something we simply cannot decipher without running some diagnostic tests first.

"You and your partner do have control over many different lifestyle and nutrition-related habits that can impact your fertility status."

Where to Begin?

To begin, ask your doctor for a sperm analysis to take a peek at the overall health of your partner’s swimmers. When performing a sperm analysis, we’re looking at three key things:

  1. The Number of Sperm: how many sperm actually exist in your partner’s semen?
  2. The Size and Shape of those Sperm: (aka morphology) this is key in order to penetrate an egg successfully.
  3. The Ability of Sperm to Move Correctly: (aka motility) sperm moving backwards simply won’t make it during the journey to join the egg.

When taking all of the factors above into consideration, research suggests up to 90% of male infertility issues result from abnormal sperm count (see #1 above).

There are other factors to take into consideration as well, such as pH, liquefaction, and volume, but as outlined above, healthy count, morphology, and motility are crucial.

Nutrients Vital To Sperm Health

If you or your partner suspect there may be some male factor involved in your inability to get pregnant, don’t panic!

There are plenty of easy-to-implement steps your partner can take in order to optimize his sperm health. New sperm are created and matured about every 64 days, so if you and your partner are thinking about having a baby, ideally you should plan on working on his sperm health a little over two months before trying to conceive.

Take a look at the guide below to ensure your partner’s sperm are Michael Phelps quality swimmers.



How it Helps: Reduces damage to cell membranes, DNA damage, and inflammation to improve overall sperm function.

Nutritional Sources: Cabbage, broccoli, oysters, lentils, avocados, and oranges.

To Supplement: Take 200mg daily.


How it Helps: Low zinc status or deficiency has been linked to low testosterone levels and poor sperm quality.

Nutritional Sources: Lamb, oysters, pumpkin seeds, chickpeas, mushrooms, kefir, yogurt, and beef.

To Supplement: Take 200mg daily.

Vitamin C

How it Helps: Integral for sperm motility. What good is having a billion swimmers if none of them can move in the right direction?!

Nutritional Sources: Chili peppers, kale, lemons, kiwis, persimmons, strawberries, oranges, and papaya.

To Supplement: Take 1000mg daily.

Vitamin B12

How it Helps: Plays an important role in sperm production and development. It also prevents DNA damage inside sperm cells.

Nutritional Sources: Foods high in vitamin B12: liver, sardines, clams, beef, tuna, nutritional yeast, dairy, salmon, and eggs.

To Supplement: Take 25mg daily.

Omega-3 Fatty Acids

How it Helps: A deficiency of DHA, a type of omega-3 fatty acid, may lower sperm count and motility as well as contribute to increased abnormal sperm shape.

Nutritional Sources: Mackerel, salmon, cod liver oil, herring, anchovies, sardines, and omega-3-enriched eggs.

To Supplement: Take 1000mg daily (make sure you’re getting at least 500mg of EPA and 500mg of DHA).

Other Important Factors

In addition to a nutrient-dense diet, it’s important to address the following factors below when it comes to boosting sperm health:

1. Smoking & Alcohol Consumption

Cigarettes and alcohol have been linked to decreased sperm production and increased sperm abnormalities.

Make sure your partner isn’t smoking cigarettes or drinking alcohol excessively. Five drinks a week are fine, but any more than that and he’s going to want to cut back.

Hello, mocktail hour!

2. Caffeine Consumption

Caffeine may lead to a lower sperm count.

Limit caffeine to less than 200mg a day (equal to about 1 cup of coffee).

If it’s too hard to go cold turkey, have him switch to black tea or half-caff first.

3. High Temperature

Keep the family jewels cool.

Sperm production occurs at a very specific temperature and overheating testicles can impede sperm production, so this means saunas and hot tubs more than twice a week for 15 minutes are out.

If putting a laptop on his lap is common practice, have him switch to using a desk with the laptop or separating the computer from his nether region in a different way.

Additionally, loose-fitting clothing and boxers instead of briefs or boxer briefs may help testicles stay at a cooler temperature.

Moving Forward

Infertility can sometimes feel out of our control and bring with it a unique combination of heartache and frustration.

I want you to know that you and your partner do have control over many different lifestyle and nutrition-related habits that can impact your fertility status.

Use this guide moving forward to make more informed decisions when it comes to trying to conceive with your partner.
