Water makes up more than 55 percent of our bodies, more than 70 percent of our hearts and brains, and over 80 percent of our lungs and blood. It even occupies 31 percent of our bones!
Water is essential to us in a myriad of ways, from the body at large to the most minute aspects of our health. The health implications of drinking enough water are immense—especially when it comes to fertility.
KEY INSIGHT
When a woman is chronically dehydrated, the reproductive system is usually the first system in the body to shut down — because it is not directly vital to survival. Hydration isn't a nice-to-have for fertility; it's foundational.
Five reasons why water is absolutely essential to reproductive health:
1. Water Improves Egg Health and the Reproductive System
Water allows nutrients to be absorbed properly by our bodies and organs, including the ovaries. Healthy eggs make for healthy conception and healthy babies—the best reason of all to drink up.
2. Water is Essential to Fertile Cervical Mucus
Cervical mucus is a fluid secreted by the cervix and is an incredibly important aspect of fertility. It's made of 90 percent water. Drinking plenty of water thins out and increases the production of cervical mucus, increasing fertility and aiding sperm on its journey toward your egg.
90%
Cervical mucus is 90% water — making adequate daily hydration one of the most direct ways to support sperm mobility and conception.
3. Water Assists Hormone Transport
Many fertility issues are related to hormonal imbalance in our bodies. In fact, more than 30 percent of infertility cases in women worldwide are caused by hormonal issues, including thyroid imbalance, pituitary dysfunction, insulin resistance, and more.
Hormones travel throughout the body—for instance from your brain to your ovaries—through the blood. And guess what blood is mostly comprised of? Water, of course. By drinking adequate water, we can support the transportation of hormones throughout our bodies, boosting fertility.
📊 WHAT THE RESEARCH SAYS
More than 30% of infertility cases in women worldwide are caused by hormonal issues — including thyroid imbalance, pituitary dysfunction, and insulin resistance. Because hormones travel through the bloodstream (which is largely water), chronic dehydration can directly disrupt the hormonal signals your reproductive system depends on.

4. Water Rids the Body of Harmful Toxins
If we're not supporting our body's natural ability to rid itself of dangerous toxins, they start to build up and cause health issues—infertility included.
The kidneys and liver rely heavily on water to function properly. The kidneys rid the body of toxins through the creation of urine—and urine is dependent on adequate water. Drinking enough water also allows the liver to rid your body of more toxins, helping it do its job faster and with greater ease.
"When a woman is chronically dehydrated, the reproductive system is usually the first system in the body to shut down, as it is not directly vital to survival."
5. Water is Essential to the Production of Breast Milk
Proper hydration is very important when it comes to breast feeding. Breast milk is 90 percent water and a common cause of low milk production is inadequate water consumption. Getting in the habit of drinking plenty of water throughout the day now will set the stage for healthy breast milk production after birth since you'll already be used to having your water bottle by your side.
When a woman is chronically dehydrated, the reproductive system is usually the first system in the body to shut down, as it is not directly vital to survival. That's why it's time to pay close attention to your water intake—especially if you're trying to conceive.
⚠️ IMPORTANT
Aim for at least eight glasses of water per day — and more if you're exercising, breastfeeding, or in a warm climate. Not all hydration is equal: sugary drinks, excessive caffeine, and alcohol can actively work against your fertility goals by stressing the liver, disrupting hormones, and depleting key nutrients.
Be sure to drink eight glasses of water—or more—every single day. After just a few days of increasing your water intake, you're sure to feel more focused, balanced, and healthy. Plus, you'll be improving your cervical mucus quality, assisting hormonal transport, detoxifying your body, and boosting your overall reproductive health. Let's raise our water bottles to that!

Frequently Asked Questions
How much water should I drink when trying to conceive?
At a minimum, aim for eight 8-ounce glasses (about 2 liters) of water per day. If you're exercising, in a warm climate, or actively trying to conceive, you may need more. Signs of good hydration include pale yellow urine and consistent energy throughout the day.
Can dehydration really affect my fertility?
Yes. Chronic dehydration can impair cervical mucus production, disrupt hormone transport through the blood, and compromise the liver and kidneys' ability to clear toxins — all of which have a direct impact on reproductive health. The reproductive system is often the first to shut down under physiological stress, including dehydration.
Does the type of water I drink matter?
Filtered water is generally preferable to tap water when trying to conceive, as it reduces exposure to chlorine, heavy metals, and other potential endocrine disruptors. Avoid excessive consumption of sparkling water with added flavors, which may contain additives that aren't fertility-friendly.
