Sperm cells and an egg

What Role Does Sperm Play In The Success Of IVF?

This week Dr Simone Rofena, our medical consultant in Reproductive Medicine talks to us about male infertility and the role sperm plays in IVF.

50% of the reasons for a couple’s infertility is down to male infertility which is very important in the couple’s diagnostic. There are three parameters we assess when considering the capability of a sperm to fertilise an egg.

  1.     Sperm count

The sperm total account must be over 15 million to be considered normal.

  1.     Motility

Motility of the sperm is also important and we would be happy with 40% of sperm having progressive motility.

  1.     Morphology

When we analyse sperm, we look at the head, neck and tail. Morphology can affect any of these three parts, so for a sperm to be considered normal they must be normally shaped.


There are several things that can be done to contribute to improving sperm count, motility and morphology. For example:

  • Good Lifestyle
  • Good Nutrition
  • Supplements

Often when men get poor results on a seamen analysis they worry they might not be able to conceive a baby but try not to worry too much as it only takes one good sperm to create a pregnancy.
