Sperm Test

Sperm testing is a quick, non-invasive way of estimating a man’s fertility potential. The test includes counting the concentration of sperm and evaluating their movement.

Ideally, a sperm sample should be assessed at a fertility clinic to ensure that qualified reproductive biologists or reproductive technologists do the sperm test properly.

There are important sperm parameters that influence the chances of natural conception and also guide the type of fertility treatment that can be done. The important basic factors are:

  1. Sperm Concentration
  2. Motility or Movement
  3. Morphology or Shape
Fertility clinics also assess whether there is any bacterial activity in the semen. In some cases there also could be an inflammation present in the glands, like the prostate. This can be a contributing factor in failing to conceive, since the inflammatory response has a negative effect on sperm quality. Fortunately this can be cleared up easily by the right antibiotics on prescription from the clinic.
There also are lifestyle factors that may influence sperm quality, but the most common factor is men who cycle more than four hours per day for six days a week. The extended time that the testicles are ‘trapped’ in the generated heat and Lycra pants reduces sperm production and quality.


Testosterone injections are a big culprit that affect sperm production significantly. They actually cause production to stop completely. Some men have testosterone supplementation for different reasons. such as libido, erectile dysfunction, muscle development and weight loss, but the effect on the sperm is the same. Fortunately the effect will wear off in three to four months after the last injection, and the sperm count then should be back to normal. Long-term use of testosterone will have more permanent effects on sperm production.

Sperm test results are available in two to three days. A test is a good start at assessing fertility potential.
