Liquid crystal thermography of the testicles in the diagnosis of infertility.

The use of liquid crystal thermography (LCT) of the testicles in diagnosis of infertility was investigated. Varicocele, the most common cause of male infertility, is easily detectable by LCT. The technique may be used as a control after surgical treatment. In the majority of patients with oligo-azoospermia, LCT corresponded to physical examination of the testicles. In patients with oligo-azoospermia and both testicles normal to palpation, LCT is useful method for determining the colder testicle for biopsy purposes.
