What Is Low Sperm Count (Oligospermia)?

Low sperm count, also called oligospermia, means the semen has fewer sperm than average.

  • The World Health Organization (WHO) treats a count below 15 million sperm per millilitre as low.
  • “Semen” is the fluid released during ejaculation. It carries the sperm.
  • Doctors group low sperm count into levels, explained below.

What Are the Types of Low Sperm Count?

  • Mild oligospermia: around 10 to 15 million per millilitre.
  • Moderate oligospermia: around 5 to 10 million per millilitre.
  • Severe oligospermia: around 1 to 5 million per millilitre.
  • Cryptospermia: zero or only rare sperm in the sample.

What Is Cryptospermia?
