Over a 7-year period 43 patients who underwent sex-chromatin and cytogenetic studies in the investigation of a disorder related to reproductive function were found to have abnormalities of the sex or autosomal chromosomes that could not have been detected by routine buccal smear. Therefore, testing for sex chromatin is of no value to the clinician, because full chromosome analysis must be performed irrespective of the findings from the buccal smear. However, the sex-chromatin test is an aid to the cytogeneticist in interpreting the chromosome analysis. In addition to those with amenorrhea and oligospermia or aspermia, persons with hypospadius and those to be treated with fertility drugs should undergo cytogenetic studies.
