How ExSeed Measure Sperm


Semen volume refers to the total amount of fluid released during ejaculation. A typical volume is above 1.5ml. Hypospermia, which is characterized by semen volume below 1.5ml, can occur due to factors such as hormonal imbalances or blockages in the ducts.

Sperm concentration measures the number of sperm cells per milliliter of semen. A standard concentration is over 15 million sperm cells per milliliter. Oligospermia occurs when the concentration falls below 15 million sperm cells per milliliter, while azoospermia means there are no sperm cells present.

Sperm motility refers to the forward movement of sperm cells. Effective fertilization requires fast travel through the female reproductive system, which necessitates strong forward motion. Our algorithm measures forward motility, also known as progressive motility. Normal motility is considered to be over 32% of sperm cells moving forward; below this level is referred to as asthenozoospermia.
