How do I improve sperm count? The useful first step is to separate what you can see from what a semen test can measure. Food patterns, body weight, and overall health can matter, but semen thickness or a single drink cannot tell you your sperm count. A semen analysis can measure count, movement, shape, and volume, then give you and your clinician something specific to discuss.
What does sperm count actually mean?
Sperm count is the number of sperm in semen. It is only one part of fertility. Movement, called motility, and shape, called morphology, also matter. Semen can look thick or watery for many reasons, so appearance alone cannot tell you whether your count is high, low, or typical.
Our Semen Analysis Basics guide explains what the lab measures, how collection works, and why repeat testing may be part of the conversation.
Can weak sperm still lead to pregnancy?
Yes. A semen result is not a simple yes-or-no answer about whether pregnancy can happen. Count, movement, shape, timing, the other partner’s reproductive health, and many other factors can all be part of the picture. If pregnancy has not happened when expected, both people in the relationship can benefit from an evaluation rather than placing the whole question on one person.
For the person releasing eggs, testing may include hormone and ultrasound-based information. Ovarian Reserve Testing explains AMH, FSH, and antral follicle count in plain language.
What foods may support sperm health?
There is no single food that changes a sperm count overnight. Still, research gives a few practical places to start when you are planning a clinician conversation.
- Tomatoes and other red produce: Tomatoes are a main dietary source of lycopene. In a 12-week randomized, placebo-controlled study of 60 healthy volunteers, a lycopene formulation was linked with more fast-moving sperm and a higher proportion of normally shaped sperm. The report notes that larger studies, including studies in people with fertility problems, were still needed. Read the lycopene trial report.
- Zinc-containing foods: The NIH Office of Dietary Supplements lists oysters, meat, fish, poultry, seafood, beans, nuts, whole grains, eggs, dairy, and fortified cereals as zinc sources. Zinc is a nutrient your body uses to make DNA and proteins. See the NIH zinc guide for food sources and supplement safety details.
- A pattern you can keep up: In a randomized trial of 56 men with obesity, an 8-week low-calorie weight-loss program was associated with a 1.49-fold increase in sperm concentration and a 1.41-fold increase in sperm count. The gains remained at one year among participants who maintained their weight loss. Semen volume and movement did not change in that study. Read the weight-loss trial.
What drink can boost sperm?
A drink is not a shortcut for sperm count. The tomato research used a lycopene formulation, not tomato juice or another beverage, and it measured semen features after 12 weeks. If you are trying to make sense of a drink, powder, or supplement ad, bring the full label to your visit so a clinician can put it alongside your health history and semen results.
How fast can sperm count change?
Expecting a change in days can set you up for frustration. The studies here followed people for weeks or longer: 12 weeks in the lycopene trial and eight weeks before the first semen measurement in the weight-loss trial. A semen analysis gives you a starting point, while a repeat test can show whether a result holds up over time.
What affects sperm count most?
There is not one answer that fits every body. Weight can be relevant: the randomized trial above enrolled men with obesity and found higher concentration and count after diet-induced weight loss. Testosterone is also involved in sperm production. MedlinePlus explains that testosterone testing may be used with other tests when a clinician is looking into abnormal hormone levels or difficulty getting someone pregnant.
Long-term research also makes this a real public-health question. A 2023 systematic review and meta-regression of 223 studies found declines in sperm concentration and total sperm count across samples collected from 1973 to 2018. That finding does not identify the cause of one person’s result, which is why your own history and lab testing matter. Read the 2023 sperm-count review.
Does masturbation lower sperm count?
Masturbation does not answer the bigger question of your underlying sperm production. For a semen test, the collection instructions matter because timing before collection can affect the result. Follow the laboratory’s instructions, and ask how to prepare if anything is unclear. The result is more useful when collection details are considered with it.
Why is my semen watery or thick?
“Watery sperm” and “thick sperm” are common ways to describe semen appearance. They are not medical measures of sperm count. You can still get a partner pregnant when semen looks watery, and thick semen does not confirm a higher count. A semen analysis is the better next question because it separates semen volume from count, movement, and shape.
| What you notice or ask | What it can tell you | Useful next step |
|---|---|---|
| “My semen looks watery.” | Appearance alone cannot measure count or fertility. | Ask about a semen analysis. |
| “I want thicker semen.” | Thickness is not a target that confirms more sperm. | Focus on measurable results: volume, count, movement, and shape. |
| “I want to improve count fast.” | Research discussed here measured changes over weeks, not days. | Bring your timeline and health history to a clinician. |
| “Can we still become pregnant?” | Pregnancy depends on more than one semen measure. | Consider evaluation for both partners when appropriate. |
Before you order a supplement or follow an ad
- Ask for the full ingredient list and the amount of each ingredient.
- Ask whether the product is being sold for sperm count, erections, or both. These are different concerns.
- Bring every medicine and supplement you use. The NIH notes that zinc supplements can interact with some medicines, including certain antibiotics, penicillamine, and thiazide diuretics.
- Be especially careful with products sold as sexual enhancement. The FDA’s health-fraud database warns that many products marketed for sexual enhancement may contain dangerous hidden ingredients.

A clinician visit would help if you are trying to conceive, have a concerning semen result, or have questions about hormones; bring any semen-analysis report, your medicines and supplements, and a brief timeline of your concerns.
