Sperm Function and Motility Profile (Quantitative Analysis)
This test evaluates key characteristics of sperm, including motility (movement) and viability, to assess reproductive health and potential fertility.

What This Test Measures
Sperm motility and morphology are critical for successful fertilization. This test typically includes measurements of sperm count, movement patterns (e.g., progressive vs. non-progressive motility), and structural integrity. Some labs may also assess sperm DNA fragmentation or other functional markers depending on the protocol.
Why It’s Ordered
Doctors may recommend this test if you’re struggling to conceive, experiencing recurrent miscarriages, or if you have known conditions affecting sperm production or function. It can also be part of a broader evaluation for male infertility.
Sample Collection and Preparation
Sperm is collected via semen analysis, often after sexual stimulation or masturbation. The sample is examined under a microscope to assess movement, shape, and overall health. Some tests may require fresh or stored semen, depending on the method used.
What to Expect Before the Test
Avoid ejaculation for 2–5 days before testing to ensure a representative sample. Wear loose clothing and avoid tight underwear to prevent overheating, as this can impact sperm quality.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions
Low sperm motility or abnormal morphology can indicate underlying issues like hormonal imbalances, genetic factors, or exposure to toxins. Highly fragmented DNA may suggest oxidative stress or other cellular damage, which could affect fertility outcomes.
What does a low sperm motility or count mean?
Can diet or lifestyle changes improve sperm quality?
