Patient's question:
A single sperm can live for 3-5 days, but I feel my wife is obviously not happy. How many sperm can a man produce in his lifetime?Doctor's answer:
The characteristics of semen are that the volume of semen per ejaculation is 3-6 milliliters, with 0.2-400 million sperm per milliliter. Frequent ejaculation can lead to a decrease in semen volume, especially sperm count. The quality and quantity of sperm are essential conditions for fertilization. If the sperm count in semen is less than 20 million per milliliter, the chances of fertilization significantly decrease. If it is less than 4 million, fertilization is not advisable, making this latter value an indicator of male infertility. If a certain drug can reduce the sperm count to this level, it can be considered to have anti-fertility effects. Additionally, at least 60% or more of the sperm in the semen must have normal morphology and motility to achieve fertilization.
