Semen analysis is the cornerstone of investigation for male infertility

Around one in four couples will see their gp about infertility problems. Large epidemiological studies show that failure or difficulty in conceiving a child is a surprisingly common, worldwide problem with between one in six and one in seven couples classed as sub-fertile. Sperm dysfunction is the most common cause of infertility and affects one in fifteen men. Studies using semen assessment as the criteria for sub-fertility show that up to one in five 18-year-olds are classed as sub-fertile. Recent reports suggest that the incidence of male infertility is increasing. [With links to the evidence base]
