Sperm DNA Fragmentation (SCD) Test – Advanced Fertility Assessment for Men

Description

Why You Need This Test

The Sperm DNA Fragmentation (SCD) Test is a critical diagnostic tool for men experiencing unexplained infertility, recurrent miscarriages, or failed IVF/ICSI cycles . Unlike a standard semen analysis, which evaluates sperm count, motility, and morphology, the SCD test goes deeper—assessing the integrity of the sperm’s DNA .

High levels of DNA fragmentation can significantly reduce:

• The chances of natural conception
• Success rates in assisted reproductive technologies (ART)
• Embryo quality and implantation potential

This test is especially recommended for men with:

• Unexplained infertility
• History of recurrent pregnancy loss
• Previous failed IVF or ICSI attempts
• Advanced paternal age (over 40)
• Exposure to toxins, smoking, or heat (e.g., saunas, laptops)
• Varicocele or genital infections

By identifying DNA damage early, this test helps guide treatment decisions such as lifestyle changes, surgical correction, or advanced fertility interventions.

Symptoms That Indicate This Test

While sperm DNA fragmentation often has no physical symptoms , consider this test if you or your partner are facing:

• Inability to conceive after 12 months of unprotected intercourse
• Recurrent miscarriages (two or more)
• Poor embryo development during IVF
• Low sperm motility or abnormal morphology
• Lifestyle or environmental risk factors (smoking, obesity, radiation, chemotherapy)
• Varicocele diagnosis

Even with normal semen analysis results, high DNA fragmentation can be a hidden cause of infertility.

Natural Production & Causes of Fragmentation

Sperm DNA is naturally packaged and protected during spermatogenesis (sperm production). However, DNA damage can occur due to :

• Oxidative stress (from infections, smoking, pollution)
• Abnormal sperm maturation
• Heat exposure (tight clothing, prolonged sitting)
• Varicocele (enlarged veins in the scrotum)
• Advanced age
• Chronic illnesses or hormonal imbalances

The SCD (Sperm Chromatin Dispersion) test detects breaks in sperm DNA by analyzing how the chromatin disperses under controlled conditions—providing a clear percentage of fragmented sperm.

What Happens If Untreated

Ignoring high sperm DNA fragmentation can lead to:

• Prolonged infertility
• Increased risk of miscarriage
• Failed fertility treatments
• Need for more invasive and costly ART procedures

Early detection allows for timely interventions such as:

• Antioxidant therapy
• Lifestyle modifications
• Varicocele repair
• Use of testicular sperm in IVF (which may have lower fragmentation)

Treating the root cause improves fertility outcomes and reduces emotional and financial strain.

How to Prepare for the Test

To ensure accurate results:

• Abstain from ejaculation for 3–5 days (not less than 2 or more than 7 days)
• Avoid alcohol, smoking, and recreational drugs for at least 48 hours
• Stop antioxidant supplements if advised by your doctor (may affect results)
• Avoid saunas, hot tubs, or prolonged sitting before the test
• Stay well-hydrated

Semen is collected via masturbation into a sterile container at the lab—no home collection.
