What are the signs of male infertility, and when should I get tested?
Many males with infertility do not experience any noticeable symptoms. It is common to feel healthy, maintain normal sexual function, and still have an underlying issue affecting sperm health. As a result, fertility concerns are often not identified until pregnancy takes longer than expected.
In general, fertility testing is recommended when pregnancy has not occurred after one year of regular, unprotected intercourse. If a female partner is over the age of 35, evaluation is typically recommended after six months.
Earlier testing may also be appropriate for men with certain medical histories or risk factors, including:
- Prior testicular injury or surgery
- History of infections affecting the reproductive tract
- Known genetic or chromosomal conditions
Some males also pursue fertility testing proactively before trying to conceive, particularly if they are planning for the future or considering sperm freezing.
Potential Causes of Male Infertility
Male infertility can stem from complications that affect sperm production, quality, or delivery. Common conditions and factors that can impact sperm health include:
- Varicocele
- Azoospermia (obstructive or non-obstructive)
- Low sperm count (oligospermia)
- Poor sperm motility or morphology
- Hormonal imbalances (e.g., low testosterone)
- Genetic or chromosomal conditions
- Infections or structural blockages
- Lifestyle or environmental factors
- Unexplained infertility
In certain cases, more than one issue can be present at once.
What is a semen analysis, and why does it matter?
A semen analysis is a non-invasive test that is often the starting point of a male fertility evaluation. The analysis provides detailed information about reproductive health, allowing specialists to determine how likely sperm are to reach and fertilize an egg. The test examines several key aspects of sperm, including:
- sperm count (how many sperm are present in the sample)
- motility (how effectively sperm are able to swim)
- morphology (the size and shape of sperm)
- semen volume (the total amount of fluid produced during ejaculation)
These parameters are then measured against reference ranges established by the World Health Organization (WHO) to assess whether sperm health falls within normal limits.
To prepare, patients are asked to abstain from ejaculation for two to five days before providing a sample. The collection process is private, and your care team will walk you through everything well in advance so there are no surprises.
While the idea of semen testing can feel uncomfortable for some patients, the process itself is relatively quick and straightforward. The semen analysis is an essential step in the evaluation process, offering valuable insight that helps guide the rest of the fertility workup and treatment plan.
What other male fertility tests might be recommended?
Depending on what the semen analysis reveals, your provider may recommend additional evaluations. These tests help build a clearer, more complete understanding of what may be affecting fertility.
Medical History and Physical Examination
Before any lab work, your provider will conduct a thorough review of your medical history to gain additional context that may help inform your evaluation plan. During this discussion, your provider may ask about prior surgeries, medications, chronic health conditions, injuries, infections, and lifestyle habits.
After reviewing your medical history, your provider will also conduct a physical examination to check for any anatomical concerns that may be impacting your fertility, such as varicoceles.
Hormone Testing
Hormones play a central role in sperm health and overall reproductive function. If semen analysis findings suggest an underlying hormonal issue, your provider may recommend bloodwork that assesses levels of testosterone, follicle-stimulating hormone (FSH), luteinizing hormone (LH), and prolactin.
Genetic Testing
Genetic testing may be recommended for men with very low sperm counts, azoospermia (absence of sperm in the semen), or a history of recurrent IVF failure. These tests can identify chromosomal abnormalities, such as Y-chromosome microdeletions.
