The male partner’s role in infertility has, historically, been undervalued and underdiagnosed for cultural and social reasons. However, we are now seeing progress in the analysis of men and a growing interest amongst patients in their fertility issue.

Modern-day urology means that spermatozoa can be obtained for use in assisted reproduction techniques using different means. Over the last 10 years, we have improved the chances of achieving good results whilst reducing the invasive nature of the process and improving the quality of samples obtained in cases in which this was not previously possible. Men who have undergone a vasectomy, cases in which the sperm duct is obstructed or patients with cystic fibrosis are common examples in which adequate spermatozoa may be obtained through a simple testicular puncture under local anaesthetic.
