Oligosiderite is a rare mineral that is a type of iron oxide-hydroxide. It is a brown or yellow-brown mineral that is often found in iron ore deposits. The name "oligosiderite" comes from the Greek words "oligos," meaning "little," and "sideros," meaning "iron," as the mineral contains only a small amount of iron. It is typically formed through the slow oxidation of iron-rich rocks and is often found in association with other iron oxides and silicates.
Oligozoospermia is a medical term that refers to a condition where a man's semen contains a low concentration of motile sperm, defined as fewer than 15 million sperm per milliliter, and fewer than 32% of the sperm are normally moving.
