EDITOR—Giwercman et al evaluated the need for screening for carcinoma in situ of the testis in oligozoospermic men from infertile couples.1 They concluded that these men do not have an increased risk of carcinoma in situ, therefore implying that screening is not justified.
Their study fails to provide the information required to form a proper judgment on the potential benefits of screening. Although no cases of carcinoma in situ of the testis were detected among the 207 men studied, the confidence intervals reported are compatible with a prevalence of almost 18 in every 1000 men and a relative risk 4.6 times that in the general population. This represents a significantly increased risk. To put this in context, the detection rate for breast cancer in the first wave of the NHS breast screening …
