Sperm fertilizing ovum.
And Baby Makes Three: Urologists Make Vast Inroads in Treating Infertility

Previously infertile men are becoming biological fathers today because of the innovative thinking of urologists, whose influence is apparent in the many aspects of the diagnosis and treatment of infertility. Some of the key discoveries in this arena include the importance of semen quality in achieving conception and the role of varicoceles (varicose veins of the testis) in causing infertility. Advances have been made in the use of testicular biopsies, ultrasound and laboratory assays in evaluating fertility problems, and urologists have played a part in the emergence of endoscopy, microsurgery and fertilization techniques in treating fertility problems in men.

Name an area and you can see just how far this specialty has come since Dutch microscopist Antonie van Leeuwenhoek first viewed and described spermatozoa in 1677 and since others observed the sperm-ovum fertilization link two centuries later.
