If you’re over 40 or are unable to get pregnant with your own eggs, donor eggs are often suggested as a way to help you and your partner have the baby of your dreams. This is an expensive and emotionally demanding journey but once you have made the decision, you want the very best chance of success.

What about your partner? What tests have you done to check his sperm quality?  It would be such a shame if  you overcame your egg problem but had an undetected sperm problem that still led to failure for you.

In fertility investigations, we often neglect the man and offer him only one test- a semen analysis. This simply looks at the number of sperm, how well they can swim and what they look like on the outside but those aren’t all that’s needed for a healthy baby. The most important part of a sperm is its DNA.  It’s the sperm DNA and the egg DNA that make an embryo. If the sperm DNA is damaged it is much less likely to lead to a pregnancy.   Even if a pregnancy occurs, there is a greater chance of miscarriage.

We have shown that 80% of men with a normal semen analysis find they have sperm DNA damage during more detailed fertility investigations. Having a sperm DNA test before you start your treatment with donor eggs will give you more choices. If the sperm DNA is highly damaged you can consider donor sperm or donor embryos as well.
