Code Description

ICD-10 N46.1 is a billable code used to indicate a diagnosis of oligospermia.

Key Diagnostic Point:

Oligospermia is defined as a condition in which a male has a lower than normal sperm count in his semen. Specifically, it is characterized by fewer than 15 million sperm per milliliter of semen. This condition can significantly impact male fertility, as sperm count is a critical factor in the ability to conceive. Oligospermia can arise from various causes, including hormonal imbalances, genetic factors, infections, and environmental influences such as exposure to toxins or heat. It is often associated with other male reproductive disorders, including hydrocele, orchitis, and penile disorders. The diagnosis of oligospermia typically involves a semen analysis, which assesses sperm concentration, motility, and morphology. Treatment options may vary depending on the underlying cause and can include lifestyle modifications, hormonal therapy, or assisted reproductive technologies. Understanding the complexities of oligospermia is essential for effective andrological management and addressing male infertility.

Frequently Asked Questions

What is the difference between oligospermia and azoospermia?

Oligospermia refers to a low sperm count (fewer than 15 million sperm/mL), while azoospermia indicates a complete absence of sperm in the semen.
