What are the signs of male infertility, and when should I get tested?
Most causes of male infertility do not cause noticeable symptoms. Many men feel completely healthy and may not realize there is a fertility issue until pregnancy does not occur after months of trying. Because male infertility is often silent, fertility testing plays an important role in identifying concerns early.
Fertility testing for men is typically recommended if pregnancy has not occurred after 12 months of unprotected intercourse, or after six months if the female partner is over age 35. Earlier evaluation may also be appropriate for men with a history of testicular injury, surgery, infection, cancer treatment, or known genetic conditions, even if they are not currently trying to conceive. Testing can provide valuable insight and help guide future family-building decisions.
Potential Causes of Male Infertility
Male fertility testing can help identify a range of factors that may affect sperm production, function, or delivery. Common causes and contributing factors include:
- Enlarged veins within the scrotum (varicocele)
- A complete absence of sperm in the semen, which may be caused by a blockage or a problem with sperm production (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 some cases, more than one factor may be involved, and fertility testing helps clarify how these issues impact reproductive health and treatment planning.
What is a semen analysis, and why does it matter?
A semen analysis is one of the most important and commonly used tests for evaluating male fertility. It is often the first step in understanding sperm health and identifying factors that may affect the ability to conceive. The test provides detailed information about how sperm are produced, how they move, and how well they may function.
During a semen analysis, the sample is evaluated for several key factors, including sperm count, motility (movement), morphology (shape), and semen volume. Results are interpreted together rather than in isolation, allowing fertility specialists to identify patterns that may point to hormonal, structural, genetic, or lifestyle-related concerns.
Sample collection is straightforward and private. Patients are typically asked to abstain from ejaculation for two to five days before providing a sample to ensure the most accurate results. Your care team will provide clear instructions and answer any questions in advance. At Reproductive Biology Associates, semen analysis is handled with discretion and care, and the results play a critical role in guiding next steps in fertility evaluation and treatment.
What other male fertility tests might be recommended?
Depending on semen analysis results and individual medical history, additional testing may be recommended to better understand the underlying causes of male infertility. These evaluations help identify hormonal, genetic, or physical factors that may affect sperm production or function and guide personalized treatment planning.
Medical History and Physical Examination
A detailed review of medical history and a physical examination help identify risk factors such as prior surgeries, infections, injuries, or anatomical concerns like varicoceles. This evaluation provides important context for interpreting test results and determining next steps.
Hormone Testing
Blood tests may be used to measure hormone levels that influence sperm production and reproductive function, including testosterone, follicle-stimulating hormone (FSH), luteinizing hormone (LH), and prolactin. Hormone testing can help uncover imbalances that contribute to infertility.
Genetic Testing
In certain cases, genetic testing may be recommended, particularly for men with very low sperm counts, azoospermia, or recurrent IVF failure. These tests can identify chromosomal abnormalities or Y-chromosome microdeletions that may impact fertility and treatment options.
