Sperm count refers to the number of sperm present in a man's semen during ejaculation. It is an important factor in male fertility, as a higher sperm count increases the chances of successful conception. A normal sperm count typically ranges from 15 million to over 200 million sperm per milliliter of semen. Factors that can affect sperm count include lifestyle choices, environmental influences, and health conditions. For instance, excessive alcohol consumption, smoking, and exposure to toxins can lower sperm count. Regular check-ups with a healthcare provider can help monitor and address any fertility concerns related to sperm count.
