In seminal fluid, the amount of spermatozoa is :

  • A.3 thousand spermatozoa per ml
  • B.50 billion spermatozoa per ounce
  • C.25 trillion spermatozoa per pint
  • D.100 million spermatozoa per ml

Answer: D

Seminal fluid contains about 100 million spermatozoa per ml.

A normal ejaculate of about 2 to 5 ml contains tens of millions of sperm per millilitre; the classic textbook figure is about 100 million per ml, and counts below about 15 million per ml are considered low.

3 thousand per ml is far too few, and the figures per ounce and per pint (50 billion and 25 trillion) are wildly too high when converted to millilitres.
