Recent studies suggest that as many as one couple in six suffer from infertility.
In about half of all couples affected, their infertility is due in whole or in part to problems with the male partner. Either no sperm are produced, or those that are produced are not capable of fertilising an egg. Despite the tremendous advances in reproductive biology which have taken place over the past ten years, our understanding of the causes of male infertility, and therefore our ability to treat it remains very poor. This is a widely accepted and successful solution to these couples' problems. In addition, research is currently being done to help us try to understand the causes of male infertility and to develop effective methods of treatment.
