This book contains an estimate of some elements and vitamins in semen to men suffering from infertility of the type Asthenospermia, which is part of the requirements for obtaining a doctorate in sperm physiology from the Department of Life Sciences / Faculty of Science / University of Babylon. The book presents the division of infertility in men into several categories, including Asthenospermia, Normospermia, oligospermia, Azospermia and others, after relying on the World Health Organization in its fifth edition of 2010 in semen analysis and identification of those categories. The level of vitamins E (E, C) and the level of antioxidants, such as GSH, CAT, were measured. Levels of some minerals such as zinc, calcium, potassium, etc. were also estimated.
