CatSper calcium channels are vital in enabling the sperm swim and to penetrate the egg, achieving fertilisation. A defect in CatSper can render a man with normal semen parameters infertile.

'The CatSper test can guide clinicians toward more personalised, evidence-based treatment approaches, including ICSI.'
