OBJECTIVE: To report a case of 100% teratozoospermia in a patient whose family history presented a high degree of consanguinity. DESIGN: Case report. SETTING: University-based andrology clinic. PATIENT(S): A 27-year-old man undergoing infertility evaluation. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Serum hormone analysis, standard (World Health Organization) semen quality evaluation, sperm ultrastructure, lymphocytic karyotype, and polymerase chain reaction screening for Y chromosome microdeletions in peripheral blood. RESULT(S): One hundred percent teratozoospermia characterized by shape alterations of the heads and tail agenesis on standard morphology evaluation, which was confirmed using electron microscopy. CONCLUSION(S): A case of familial infertility in a consanguineous patient characterized by morphological abnormalities of spermatozoa such as tail agenesis, chromatin subcondensation, and residual cytoplasmic droplets.
