Male infertility (N46)
ICD-10 code N46 is used to classify and document male infertility, covering a range of conditions that impair male reproductive ability. These codes precisely identify different causes and types of infertility, including azoospermia (absence of sperm) and oligospermia (low sperm count), each with specific subcategories.
The ICD-10 code for male infertility includes detailed classifications such as N46.0 for azoospermia and N46.1 for oligospermia. Within these, distinctions are made between organic causes, extratesticular causes like infections or obstructions, drug-induced conditions, and systemic diseases. For example, N46.01 covers organic azoospermia, also known by terms like anorchid azoospermia or primary spermatogenic failure, while N46.022 refers specifically to azoospermia due to infection. Other codes, such as N46.8, capture various other male infertility causes like congenital or acquired disorders, including cases involving antisperm antibodies or abnormal sperm morphology. The unspecified category N46.9 helps coders mark infertility when a definitive diagnosis isn’t established, encompassing synonyms like unexplained infertility, male sterility, and fertility problems caused by systemic or environmental factors. This coding framework assists healthcare providers and coders in precisely documenting male infertility causes to support accurate diagnosis, treatment, and research.

Instructional Notations
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
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.
