Abstract
This chapter discusses the methods used for semen analysis. The analysis of semen gives limited but useful information about the hormonal condition of the individual. Many steps are involved between the endocrine prerequisites and the end product, and these steps may be disturbed by several conditions. Nevertheless, patients with a normal sperm density seldom have disorders of the hypothalamic–pituitary–gonadal axis and a simple semen analysis is often easier to accomplish than more sophisticated endocrine tests. Semen analysis is most often requested because of infertility. For the study of sperm count, motility, and morphology, the ejaculate may be produced at home and delivered to the laboratory within a few hours. For special studies, the patient may have to produce the sample at the laboratory. The sample should be protected against cooling below room temperature at least before the assessment of sperm motility. Patients living far away from the laboratory may deliver the sample to the nearby clinic, where motility and concentration is assessed and permanent preparations for the study of morphology and vitality can be made.
