Question

How many sperm cells are present in an average $\left(3mL\right)$ ejaculation?

• A. 200 million
• B. 300 million
• C. 400 million
• D. 500 million

Answer 1

The correct option is B 300 million

Around 1000 sperm cells are produced every second, which means that an adult man produces millions of sperm cells every day. The sperm cell, which is the male gamete is produced in the male testicles in thin tubes, which lead to the epididymis. The sperm cells are stored here, while they mature. The epididymis leads to the spermatic cord, which on ejaculation sends sperm mixed in with fluid from the seminal vesicles and prostate gland through to the urethra, from which the semen is released. It takes about 3 months to produce a sperm cell, from the early stage to full maturity. Normally, an amount of 2-6 ml of seminal fluid is ejaculated, typically containing 60-450 million sperm cells. The amount of seminal fluid does not necessarily provide any indication of the quality of the sperm cells and may vary from 2 to 8 ml and still be regarded as normal. The average volume of ejaculate is around 3 ml.
