The researchers wanted to see if a special formula could help improve sperm movement in rats with weak sperm. They made the rats have weak sperm by giving them a plant extract. Then, they checked the sperm's speed and how well it moved using a computer. They found that the formula made the sperm move faster and better in the medium amount. This worked as well as another known treatment and was better than low or high amounts of the formula. The formula didn't change the way the sperm moved but made more sperm and helped them move better. So, this special formula can help increase sperm numbers and improve their movement in rats with weak sperm.
