Infertility
View through CrossRef
The assessment of men with fertility problems is described in this chapter. The main causes of male infertility are testicular insufficiency due to congenital and acquired causes, obstructions of the male genital tract, genetic and endocrine abnormalities, urogenital infections, and varicoceles. Lifestyle can also have a negative influence on semen quality: smoking, obesity, drugs, and anabolic steroids influence sperm parameters and may reduce natural conception. Some chronic diseases also have a negative influence on fertility. History taking and physical examination should focus on prevalent causes of male infertility. Many decisions on diagnosis and treatment of male infertility are based on a semen analysis. It is therefore essential that the investigation is performed according to the recommendations of the world health organization manual for semen analysis.
