Tim S., a 40-year-old male, and his wife undergo fertility testing. The laboratory reports that the patient's semen contains a scanty amount of sperm. The physician documents this finding as

Oligospermia, which is commonly known as low sperm count. The sperm cells are less than 15 million sperm/ml (where the normal sperm count ranges from 15-200 million sperm/ml). This can be caused by medical conditions such as varicocele, infection, hormonal imbalance and so on.
