Low sperm count

why does ivf fail


Oligospermia, or a low sperm count, is diagnosed when less than 15 million sperm are seen per millilitre of sperm. If very few sperm are seen in the ejaculate, a diagnosis of severe oligospermia, or cryptozoospermia, may be given.


What is oligospermia?

According to the World Health Organization (WHO), there needs to be over 15 million sperm per millilitre of semen for a ‘normal’ sperm count. Oligospermia may decrease the chance of natural conception, but in many cases, it doesn’t completely rule out the possibility.

It’s important to remember that the number of sperm in the ejaculate is just one of several considerations which determine male fertility. In many cases, the quality and quantity of sperm can be improved with the support of a team of male fertility specialists.

What causes oligospermia

Oligospermia has many potential causes including:

  • Varicocele
  • Ejaculatory problems
  • Infection
  • Medications
  • Hormonal imbalance
  • Heat exposure
  • Stress
  • Lifestyle factors
  • Recreational drugs
  • Genetic conditions
  • Other medical conditions
