Treatment of male infertility.
Male factor infertility is a general term that describes a situation in which the inability to conceive is associated with an alteration identified in the male partner. This dysfunction may be associated with low sperm concentration (oligozoospermia), poor sperm motility (asthenozoospermia) or abnormal sperm morphology (teratozoospermia); however, generally, a disturbance of all these variables, oligoasthenoteratozoospermia, is mostly frequent in male subfertility. For many andrological disorders, it is not possible to find a reasonable cause and various uncontrolled treatments have been applied to infertile men, often just on an empirical basis. More recently, after the explosive development of modern assisted reproduction techniques (ARTs), feasible with a single spermatozoon [intracytoplasmic sperm injection (ICSI)], the treatment of male infertility has received new meaning and andrologists are no longer expected to achieve a quantitative increase in sperm number but are instead asked to improve the fertility potential of the single sperm cell in order to achieve better results in both in vitro fertilization and ICSI. Additional prospective studies are needed to better understand the possible role of therapy in ART candidate patients.

Sperm tail agenesis in a case of consanguinity.
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.
