With rising fertility challenges among couples, semen analysis has become one of the most essential tests in evaluating male fertility.
It helps doctors detect any abnormalities in sperm quality or quantity, which can directly impact the chances of conception.In this comprehensive guide from Dalili Medical, we explain when a semen analysis is needed, what the results mean, and how to properly prepare for the test.
A semen analysis is a laboratory test used to evaluate the physical, chemical, and biological properties of semen—produced by the testicles and containing sperm.
This test is typically performed to assess:
Sperm count (total number of sperm)
Motility (movement)
Morphology (shape)
Volume and concentration of semen
Presence of abnormal cells or infection
A semen analysis is commonly recommended in the following situations:
Infertility evaluation, especially after 12 months of unprotected intercourse without conception
Assessment before assisted reproductive techniques like IVF or ICSI
After infections or trauma to the reproductive tract
Post-varicocele surgery
In cases of erectile dysfunction or low libido, to rule out organic causes
To evaluate the success of vasectomy or prostate surgery
To get accurate results, follow these guidelines:
Abstain from ejaculation for 2–5 days before the test
Avoid alcohol and drugs several days prior
Avoid excessive heat, such as saunas or tight clothing
It’s best to collect the sample at the lab, but home collection is allowed if the sample is brought in within 30–60 minutes and kept at body temperature
The semen sample is collected by masturbation into a sterile container
The sample is analyzed immediately under a microscope
It is evaluated according to WHO criteria to measure all important parameters
Parameter | Normal Range |
---|---|
Volume | ≥ 1.4 mL |
Total sperm count | ≥ 39 million |
Concentration | ≥ 16 million/mL |
Total motility | ≥ 42% |
Progressive motility | ≥ 30% |
Normal morphology | ≥ 4% |
pH | 7.2 – 8.0 |
Viscosity | Normal or low |
Below-normal sperm count, possibly due to infections, varicocele, hormonal imbalance, or environmental factors.
Could indicate blockage in reproductive tract or testicular failure in producing sperm.
Reduced movement makes it harder for sperm to reach the egg.
High percentage of misshapen sperm can reduce fertilization capability.
Often a sign of infection or inflammation in the prostate or reproductive tract.
Yes. It’s recommended to repeat the test 2–3 times over a two-month period, since sperm production naturally cycles every ~74 days.
Test | Purpose |
---|---|
Hormonal panel (FSH, LH, Testosterone, Prolactin) | To assess testicular and endocrine function |
Scrotal Doppler ultrasound | To detect varicocele |
Karyotyping/genetic testing | For unexplained infertility |
Semen culture | To detect bacterial or fungal infections |
Sperm DNA fragmentation | To assess DNA quality within sperm |
Yes, 2–5 days of abstinence is ideal for accuracy.
Yes, to some extent. Staying relaxed helps.
Not always. The overall percentage of normal forms is what matters most.
Semen analysis is a simple yet crucial test for evaluating male fertility.
Minor abnormalities in sperm count or motility don’t necessarily mean infertility—they may be temporary or treatable.
If you’re experiencing delayed conception, consult a reproductive health specialist and consider a semen analysis as your first step.
