A couple is presented suffering from primary sterility for 20 years and who were selected for an IVF test, since conservative methods failed to induce a pregnancy. The ejaculate of two semen samples revealed exclusively round-headed spermatozoa in each sample. Contrary to this diagnosis, however, asthenoteratozoospermia had been diagnosed in previous investigations and the patient had been treated with tamoxifene. However, no therapy exists for the phenomenon of round-headed spermatozoa, because this defect is genetic of origin and correlates with irreversible infertility.
