Examen is a world leader in male fertility testing, based on its heritage of over 25 years in male reproductive health and fertility treatment research. We specialise in measuring sperm DNA fragmentation (known as sperm DNA damage) to help predict the likelihood of conception, miscarriage and the success of fertility treatment.

Sperm DNA damage is one of the most important factors causing male infertility. Examen has developed a range of sperm DNA diagnostics tests that empower men to take control of their own fertility.

The Exact range of tests is powered by Examen’s proprietary SpermComet® technology, proven to deliver an accurate assessment of sperm DNA damage for fertility diagnosis and information that can predict the outcome of IVF and ICSI fertility treatment.

Founded by an internationally acclaimed expert in male fertility; Professor Sheena Lewis, Examen’s Exact range of tests, powered by SpermComet®, are the go-to tests for sperm DNA damage in 80% of the UK’s leading fertility clinics.

“Over 70% of men with a normal semen analysis have sperm DNA damage, but often this isn’t discovered until after IVF has failed… For men looking for answers straightaway, our Exact tests can save the time, money and heartache associated with infertility.” Professor Sheena Lewis, CEO, Examen
