When a couple faces challenges conceiving, the conversation too often centers on the female partner, but male factors contribute to roughly half of all infertility cases. Evaluating both partners from the start is not just thorough; it is essential. Male fertility testing is straightforward, typically non-invasive, and can deliver meaningful answers quickly.
At Aspire Fertility Houston, we take a team-based approach to every evaluation, assessing both partners in parallel so that nothing is missed and no time is lost. If you have questions about your reproductive health, proactive testing is one of the most valuable steps you can take.
What are the signs of male infertility, and when should I get tested?
Male infertility rarely announces itself. Unlike some health conditions, there are usually no outward symptoms, and sperm count, motility, and morphology cannot be assessed without a lab test. Most men only discover a potential issue when a couple has been trying to conceive without success.
A fertility evaluation is typically recommended after 12 months of regular, unprotected intercourse without pregnancy, or after 6 months if the female partner is over age 35. Earlier testing is warranted if you have a history of any of the following:
Testicular injury, torsion, or undescended testicles
Prior surgery in or around the pelvic or groin area
Infections including mumps, sexually transmitted infections, or epididymitis
Known genetic or chromosomal conditions
Prior cancer treatment involving chemotherapy or radiation
A history of varicocele or other structural concerns
Even if you are not actively trying to conceive, an evaluation can provide useful baseline information and peace of mind. Early knowledge creates more options.
Potential Causes of Male Infertility
Male infertility can result from problems with sperm production, sperm function, sperm transport, or underlying hormonal and genetic factors. In many cases, more than one contributing factor is present. Common causes include:
Varicocele: Enlarged veins in the scrotum that elevate testicular temperature and disrupt sperm production. Varicocele is the most common identifiable and correctable cause of male infertility.
Azoospermia: The complete absence of sperm in the ejaculate, which may be obstructive (a physical blockage) or non-obstructive (a production failure at the testicular level).
Low sperm count (oligospermia): Fewer sperm than normal in the ejaculate, reducing the statistical probability of fertilization.
Poor sperm motility or morphology: Sperm that move inefficiently or are abnormally shaped may be unable to reach or successfully penetrate an egg.
Hormonal imbalances: Low testosterone, elevated FSH, or disruptions in other key hormones can impair sperm production at the source.
Genetic or chromosomal conditions: Conditions such as Klinefelter syndrome or Y-chromosome microdeletions can affect sperm production at a genetic level.
Infections or structural blockages: Past infections or anatomical abnormalities, including congenital absence of the vas deferens, can block sperm delivery.
Lifestyle or environmental factors: Tobacco use, alcohol, anabolic steroids, heat exposure, and certain medications can negatively affect sperm quality over time.
Unexplained infertility: In some cases, no clear cause is identified through standard testing, and further specialized evaluation may be recommended.
What is a semen analysis and why does it matter?
A semen analysis is the cornerstone of male fertility evaluation, and almost always the first test ordered. It provides a comprehensive, objective snapshot of sperm health across four key parameters:
Sperm count (concentration): The number of sperm per milliliter of semen. A normal result is generally 16 million or more per milliliter per World Health Organization (WHO) reference values.
Motility: The percentage of sperm that are actively moving, and how effectively they move.
Morphology: The percentage of sperm with a normal, well-formed shape, which affects the sperm's ability to penetrate an egg.
Volume: The total amount of semen produced per ejaculate. Low volume can indicate a hormonal issue or a possible blockage of the seminal vesicles.
Results are evaluated against WHO reference standards, and your Aspire Houston physician will walk you through what your results mean – not just as numbers, but in the context of your full clinical picture.
Preparing for a semen analysis is simple. You will be asked to abstain from ejaculation for 2 to 5 days before sample collection to ensure an accurate result. Samples are collected in a private room at the clinic using a sterile collection kit, although sometimes home collection is allowed. The process is confidential, takes only a few minutes, and is a critical foundation for understanding your fertility. One abnormal result does not confirm infertility; your physician may recommend a repeat analysis, as results can vary across samples.
What other male fertility tests might be recommended?
If semen analysis reveals abnormal results, or if your clinical history suggests an underlying issue, your Aspire Houston physician will recommend one or more of the following additional evaluations:
Medical History and Physical Examination
Every male fertility workup at Aspire Houston begins with a thorough review of your medical and reproductive history. Your physician will ask about past illnesses, surgeries, medications, lifestyle habits, and family history of genetic conditions. A physical exam, including evaluation of the testes and surrounding structures, can identify issues such as a varicocele, epididymal obstruction, or other anatomical concerns that may not appear on lab tests alone. This foundational step shapes every subsequent decision in your evaluation.
Hormone Testing
Sperm production is regulated by a precise hormonal cascade, and disruptions at any point can impair fertility. Blood tests to measure testosterone, follicle-stimulating hormone (FSH), luteinizing hormone (LH), and prolactin help identify whether an endocrine factor is contributing to poor sperm production or function. Abnormal hormone levels can point to conditions such as hypogonadism or pituitary dysfunction, many of which respond well to targeted medical treatment. Hormone testing is often ordered in conjunction with or shortly after the initial semen analysis.
Genetic Testing
When semen analysis reveals azoospermia, severely low sperm counts, or when recurrent IVF failure raises questions, genetic testing may be recommended to look for chromosomal or gene-level contributors. Common evaluations include karyotyping to detect chromosomal abnormalities such as Klinefelter syndrome, Y-chromosome microdeletion analysis to identify deletions that impair sperm production, and CFTR gene testing for mutations associated with congenital absence of the vas deferens. Genetic results carry implications for treatment planning and for understanding conditions that may be heritable, making genetic counseling an important part of this process.
How much does male fertility testing cost?
The cost of male fertility testing at Aspire Houston depends on which evaluations are recommended based on your history and clinical findings. A semen analysis is typically the most affordable and most commonly covered diagnostic test. More specialized testing, such as hormone panels, sperm DNA fragmentation analysis, or genetic screening, may involve additional costs depending on your insurance plan.
Texas does not have a state-mandated fertility insurance law, so coverage for fertility testing varies significantly by employer and plan type. Many basic diagnostic tests may still be covered when ordered for a medical indication. We recommend checking with your insurance provider before your appointment to understand your benefits. Aspire Houston's financial team is also available to help you review your coverage and explore your options before you begin.
A semen analysis is the primary diagnostic test used to evaluate male fertility. It measures the concentration, motility, morphology, and volume of a semen sample, providing an objective picture of sperm health. Results are compared to World Health Organization reference values to determine whether a sperm factor may be contributing to difficulty conceiving. A single abnormal result does not confirm infertility. Sperm quality can fluctuate, and your Aspire Houston physician may recommend a repeat test before drawing any conclusions or recommending next steps.
To get the most accurate results, abstain from ejaculation for 2 to 5 days before your sample collection. In the days leading up to the test, avoid alcohol, recreational drugs, and excessive heat exposure (such as hot tubs or saunas). Let your physician know about any medications or supplements you are currently taking, as some can affect sperm parameters. Samples are collected in a private, comfortable setting at an Aspire Houston clinic. Following these guidelines helps ensure your sample reflects your baseline sperm health rather than temporary factors.
A low sperm count, clinically called oligospermia, means there are fewer sperm per milliliter of semen than the established reference threshold. While lower counts do reduce the probability of natural conception, they do not make pregnancy impossible. Many men with low sperm counts go on to father children, sometimes with assistance through IUI or IVF with ICSI. Your Aspire Houston physician will evaluate your full semen analysis results alongside your medical history to determine what the findings actually mean for your specific fertility picture and what options are available.
In many cases, yes. Treatment depends on the underlying cause. Varicoceles can often be surgically corrected, with many men seeing meaningful improvements in sperm parameters afterward. Hormonal imbalances may respond to medication. Lifestyle changes, such as quitting smoking, reducing alcohol, or eliminating anabolic steroids, can improve sperm quality over time. For men with azoospermia or very low counts, assisted reproductive technologies such as IVF with ICSI or sperm retrieval procedures may make conception possible. Your Aspire Houston physician will review all options based on your diagnosis.
Yes, though the decline in male fertility with age is more gradual than in women. Sperm quality, including motility and morphology, tends to decrease progressively after age 40 to 45. Older men may also show higher rates of sperm DNA fragmentation, which can affect fertilization rates and embryo quality. While men can father children into later decades, age-related changes in sperm are a real clinical consideration, particularly when the male partner is significantly older. Testing can clarify whether age-related sperm factors are relevant in your situation.
Abnormal sperm motility (asthenospermia) or morphology (teratospermia) can result from infections, varicoceles, hormonal imbalances, oxidative stress, elevated scrotal temperature, genetic factors, and lifestyle influences such as smoking or anabolic steroid use. In many cases, no single cause is identified. Your physician will evaluate these findings alongside your full semen analysis and medical history to determine whether further investigation or testing is needed. Oftentimes, certain lifestyle improvements can lead to meaningful changes in sperm quality.
Yes. Several medications are known to impair sperm production or function, including testosterone replacement therapy, anabolic steroids, certain antibiotics, chemotherapy agents, and some antidepressants or antihypertensives. Over-the-counter supplements can also influence sperm health in complex ways. It is important to disclose all medications and supplements to your Aspire Houston physician before testing so results can be accurately interpreted. In some cases, adjusting or discontinuing a medication under medical guidance may lead to improvements in sperm parameters over time.
No, many causes of male infertility are treatable or manageable. Varicoceles can be surgically repaired, hormonal conditions can often be addressed medically, and lifestyle changes can meaningfully improve sperm quality in men without a fixed anatomical cause. Even in cases of azoospermia, sperm retrieval procedures may allow conception through IVF. While some causes, such as certain genetic conditions or severe testicular failure, may not be fully reversible, assisted reproductive options are often still available. An accurate diagnosis is the essential first step toward understanding what is possible for you.
