Understanding Semen Analysis: What It Measures and What Abnormal Results Mean

Dr. Lee Caperton • July 21, 2025

When a couple faces challenges in conceiving, one of the first steps in fertility evaluation is often a semen analysis. Male factor infertility contributes to approximately 40-50% of infertility cases. At Caperton Fertility Institute, with locations in Albuquerque, NM and El Paso, TX, we rely on this essential diagnostic tool to assess male reproductive health and guide personalized fertility treatments.

What Is a Semen Analysis?

A semen analysis evaluates the health and viability of a man's sperm. This non-invasive test measures multiple parameters that are crucial for successful conception:

Volume

The amount of ejaculate, with a typical normal range between 1.5 to 5 milliliters.

Sperm Concentration

The number of sperm per milliliter of semen. A normal sperm count is 15 million/mL or higher.

Motility

The percentage of sperm that are actively moving. A minimum of 40% motility is generally considered normal.

Morphology

The size and shape of sperm, assessed using strict criteria. A morphology score of 4% or more normal-shaped sperm is acceptable.

pH Level

Measures the acidity or alkalinity of semen, with a normal range from 7.2 to 8.0.

White Blood Cells

Elevated levels may signal infection or inflammation in the reproductive tract.

Liquefaction Time

Refers to how long it takes semen to liquefy after ejaculation. Normal liquefaction occurs within 20 to 30 minutes.

What Do Abnormal Semen Analysis Results Mean?

An abnormal result doesn’t automatically mean infertility. Semen quality can vary over time, so further testing is often needed to understand the full picture. Depending on the results, your provider may recommend:

Repeat Semen Analysis: To confirm initial findings.

Hormonal Testing: Evaluates hormone levels like testosterone, FSH, LH, and prolactin.

Genetic Testing: For severely low sperm counts or azoospermia, this can reveal chromosomal abnormalities or Y chromosome deletions.

Scrotal Ultrasound: Detects physical issues such as varicoceles or obstructions.

Referral to a Urologist: For evaluation and management of urological or endocrine disorders.

At Caperton Fertility Institute, we take a holistic and individualized approach to male infertility. Based on your specific diagnosis, treatment options may include:

Lifestyle changes to improve sperm health

Medical therapies to balance hormones or treat infections

Each year, National Infertility Awareness Week (April 19–25) shines a light on a journey that millions of individuals and couples experience—often quietly. At Caperton Fertility Institute, this week is more than awareness. It’s about recognition, support, and hope . Because behind every diagnosis is a person, a family, and a story that deserves to be heard. Understanding the Reality of Infertility Infertility affects 1 in 6 people worldwide , yet it’s still widely misunderstood. For many, the journey includes: Months or years of trying to conceive Emotional highs and lows Feelings of isolation or frustration Navigating complex medical decisions And while it’s common, it can still feel incredibly lonely.

Every year on April 10th, National Siblings Day gives us a moment to celebrate the lifelong bonds between brothers and sisters—the built-in best friends, the protectors, the role models. At Caperton Fertility Institute, this day holds an even deeper meaning. For many of our patients, the journey to welcoming a second child—the moment a little one becomes a big sibling—is filled with hope, resilience, and sometimes unexpected challenges. The Path to a Second Child Isn’t Always Simple Many families are surprised to learn that conceiving a second child isn’t always easier than the first. In fact, secondary infertility —the inability to conceive or carry a pregnancy after previously having a child—is more common than people realize. If you’re in Albuquerque or El Paso and struggling to grow your family, you’re not alone. At Caperton Fertility Institute, we work with many patients who are navigating this exact journey—parents who dreamed of expanding their family but find themselves needing support along the way. What Is Secondary Infertility? Secondary infertility can happen for many reasons, including: Changes in egg or sperm quality Age-related fertility decline Hormonal imbalances Complications from a previous pregnancy Underlying medical conditions No matter the cause, it can feel confusing and emotional—especially when you’ve already experienced pregnancy before. How Fertility Care Can Help You Grow Your Family If you’re hoping to give your child a sibling, there are several treatment options available depending on your unique situation. At our fertility clinics in Albuquerque, New Mexico, and El Paso, Texas , we offer: Ovulation support and monitoring Intrauterine insemination (IUI) In vitro fertilization (IVF) Donor egg or sperm options, if needed Our team creates personalized treatment plans designed to support your goals—whether you’re just starting to explore options or ready to take the next step. More Than a Diagnosis—It’s Your Family Story Secondary infertility isn’t just a medical condition—it’s an emotional journey. It can come with feelings of: Frustration Guilt Isolation You may hear things like, “At least you already have one child,” but your desire to grow your family is just as valid. At Caperton Fertility Institute, we see the full picture. We understand that every family story matters, and we’re here to support you with compassion and expertise.  Celebrating Siblings—and the Journeys That Create Them On National Siblings Day, we celebrate more than just the bond between siblings—we celebrate the journeys that made those relationships possible. From first-time parents to those returning for baby number two (or more), every path to parenthood is unique. Whether your family was built naturally, through IVF, with the help of a donor, or via surrogacy—your story is worth honoring.
