"You want me to do what? Where?"
That's the reaction you'll get from most guys when you talk about getting a semen analysis. It's like you're asking them to get a root canal done.
But for most women, we'd take that test in an instant — orgasming for a fertility test? SIGN ME UP! I'll take a pass on the blood draws, poking, prodding, imaging, dye injections, and all the rest.
But all joking aside, the semen analysis is actually one of the more useful tools in evaluating a couple's fertility. If you and your partner are having difficulty conceiving, it should be one of the first things you investigate — regardless of the fertility status of the female partner.
A number of tests may be performed during a semen analysis, but here are the five most important factors:
KEY INSIGHT
Male factor infertility contributes to roughly half of all conception difficulties — yet the semen analysis is often the last test couples think to pursue. It's simple, painless, and one of the highest-value first steps you can take.
Volume
Volume refers to the total amount of semen (the fluid that surrounds and protects the actual sperm) present in the sample. Semen volumes below 1.5 mL may mean there is a genital tract obstruction or other issue that will require further treatment.
Concentration
This is the number of sperm per milliliter. There should be at least 15 million sperm per mL. Lower concentrations may still be used for in vitro fertilization or intrauterine insemination, but will make conceiving naturally much more difficult.
15M+
Sperm per milliliter is the minimum concentration considered in the normal range — below this, natural conception becomes significantly more difficult
Count
The count is the total number of sperm in the entire sample. Ideally, it will be over 40 million. That sounds like a lot of sperm, but only a few per million will actually make it up to the egg for fertilization. Furthermore, it's not just the number of sperm that matter, it's how well they work that really makes the difference.
Motility
Motility is an assessment of how well sperm moves. Sperm is graded and categorized as either progressively motile, non-progressively motile, or immotile. At least 40 percent of sperm should be motile — that means that your boys are able to swim effectively and should be able to make the long trip to egg fertilization.

Morphology
Morphology measures how well the sperm are built and is measured as the percent of normal sperm. Criteria include length, width, ratio of length to width, area of the acrosome (the cap-like organelle at the head of sperm), and defects of the head, neck, and tail of the sperm. Morphology is very important and is actually more predictive of fertility than some of the other factors measured. If less than 4% of your sperm are normal, that's considered problematic for conception.
📊 WHAT THE RESEARCH SAYS
According to WHO reference values, normal sperm morphology is defined as ≥4% using strict Kruger criteria. Studies consistently show that morphology is among the strongest predictors of natural conception rates — even when count and motility appear normal.
what you can do
A semen analysis is simple, painless, fast, and relatively inexpensive. And you don't have to worry about getting gun shy at the doctor's office. Most of the time, you can collect your sample in the comfort of your own home.
"Fertility can change, either for better or for worse. If your results aren't great, you can make a plan to improve them, or work with what you have. At least you'll know."
A lot of guys are worried that their results may be less than stellar, but the good news is that fertility can change over time.
That's right, fertility can change, either for better or for worse. If your results aren't great, you can make a plan to improve them, or work with what you have. At least you'll know.
As GI Joe always said, "knowing is half the battle," and getting your semen analysis done is an important step on the path to conception. There's nothing wrong with knowing how healthy your sperm is. In fact, a semen analysis may help you pinpoint the cause of fertility issues you and your partner are experiencing.

Frequently Asked Questions
What are the key parameters measured in a semen analysis?
A standard semen analysis evaluates five main factors: volume (total semen amount, normal is ≥1.5 mL), concentration (sperm per mL, normal is ≥15 million), total count (ideally over 40 million), motility (at least 40% of sperm should be moving), and morphology (at least 4% of sperm should have a normal shape). Each factor tells a different part of the story about male fertility.
Can semen analysis results improve over time?
Yes. Because sperm take approximately 74 days to fully develop, lifestyle changes — including diet, supplementation, reduced heat exposure, and stress management — can meaningfully improve semen parameters within a few months. A poor result today is not a permanent verdict.
Can I do a semen analysis at home?
For collection, yes — most labs allow you to collect your sample at home and bring it in within a short window of time. There are also at-home testing kits available that measure basic parameters like concentration and motility, though a full clinical semen analysis provides more detailed and reliable data.
How does the Conceivable system actually work?
Conceivable combines three things: personalized supplement packs built from your quiz results and health data, an AI care team of 7 specialists (led by Kai, your fertility coordinator) who adjust your protocol as your body changes, and the Halo Ring for continuous biometric tracking. The system is built on 240,000+ clinical data points and 20 years of practice. It starts at $15/month.
How do I know which supplements I actually need?
Take the free 2-minute Conceivable quiz. It analyzes your cycle patterns, energy, stress, digestion, and health history to identify the specific nutrients your body needs — not a generic prenatal, but a protocol built for exactly where you are right now.
Do I need the Halo Ring to use Conceivable?
No. The Halo Ring is optional and adds continuous tracking of BBT, HRV, sleep, and blood glucose — which Kai uses to fine-tune your protocol in real time. But the personalized supplement packs and AI care team work without it. The ring is a one-time $250 purchase with no subscription required.
