Answer:
fewer in number.
Explanation:
A low sperm count also known as oligospermia can be defined as a medical condition which typically involves a man (adult male) having fewer than 15 million sperm per millilitre of semen.
Basically, low sperm count (oligospermia) is usually caused in men due to health and lifestyle factors such as smoking, alcohol or drug abuse, obesity, genetics, sexually transmitted infections (STIs), age etc.
Hence, smokers, alcohol abusers, overweight and obesity men are more likely to have sperm which are fewer in number i.e fewer than 15 million sperm per millilitre of semen.
Generally, a healthy or normal sperm motility ranges from over 20 million to 200 million sperm per millilitre of semen.
