SRD5A1 stands for Steroid 5-alpha-reductase type 1. Let's break it down into simpler parts.
Steroid: Our bodies produce many different chemicals called hormones, and steroids are one type of hormone. They help us grow and develop, and they affect many different parts of our body.
5-alpha-reductase: This is a special enzyme, which is like a tiny machine inside our body. Enzymes are like workers that help do specific tasks. 5-alpha-reductase helps to change one type of steroid hormone into another type.
Type 1: There are different versions of this enzyme in our body, and type 1 is just one of them. Think of it like there can be different models of cars, and type 1 is one particular model of the enzyme.
So, when we talk about SRD5A1, we are talking about a specific type of enzyme that helps to convert one type of hormone into another type.
