Male infertility (N46)
Clinical Information
Aspermia - A condition characterized by the complete absence of SEMEN. This disorder should be differentiated from AZOOSPERMIA, absence of sperm in the semen.
Asthenozoospermia - A condition in which the percentage of motile sperm is abnormally low.
Azoospermia - A condition of having no sperm present in the ejaculate (SEMEN).
Oligospermia - A condition of suboptimal concentration of SPERMATOZOA in the ejaculated SEMEN to ensure successful FERTILIZATION of an OVUM. In humans, oligospermia is defined as a sperm count below 20 million per milliliter semen.
Semen - The thick, yellowish-white, viscid fluid secretion of male reproductive organs discharged upon ejaculation. In addition to reproductive organ secretions, it contains SPERMATOZOA and their nutrient plasma.
Teratozoospermia - Conditions in which sperm show abnormal morphology.
