Sperm and Ejaculate Microscopic Examination (with Sperm Count)
This test examines the microscopic structure, count, and motility of sperm cells in a semen sample, often used in fertility evaluations or after potential exposure to harmful substances.

What This Test Measures
A semen sample is analyzed under a microscope to evaluate several key aspects: the number of sperm cells present (sperm count), their movement (motility), shape (morphology), and overall concentration. Some labs may also check for signs of infection or abnormal cells.
Why It’s Done
This test is typically ordered when a person struggles to conceive, after exposure to toxins (e.g., chemicals, radiation), or as part of a general health evaluation. It helps determine whether sperm quality is a contributing factor to infertility or other concerns.
Sample Collection
You’ll provide a semen sample, usually collected in a sterile container at a clinic or lab. This may be done at home with instructions or during a visit. The sample is then processed and examined under a microscope.
Preparation and Results
No special preparation is needed, but avoiding ejaculation for 2–5 days before testing may improve accuracy. Results are qualitative (descriptive) and often include a report on sperm count, motility, and morphology rather than specific numeric ranges.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Low sperm count, poor motility, or abnormal morphology can indicate infertility, hormonal imbalances, or underlying health conditions (e.g., infections, genetic disorders). It may also help identify exposure to environmental toxins or chronic illnesses affecting reproductive health.
