Male fertility and infertility

Male factor infertility accounts for 30-50% of infertility cases. Over the past two decades, there have been several papers published describing declining numbers and quality of sperms. An increasing incidence of urogenital abnormalities in the new born and rising incidences of testicular cancer from many different countries have stimulated public interest and concern about male infertility. In this review different aetiological factors in male infertility are considered with an attempt to provide an up-to-date account on the investigations and management of male infertility.
