Question

How many sperm cells are present in an average (3ml) ejaculation?
a. 200 million
b. 300 million
c. 400 million
d. 500 million

Answer 1

Hint: Testes manufacture the sperm in the scrotum, where it enters the epididymis, which is supercoiled, structure, and here the sperm mature, whenever there is ejaculation happens, the sperm releases very forcefully.

Complete answer:
- Sperm is the male gamete, which is produced in the seminiferous tubules of the testes.
- This sperm enters the epididymis and matures there, so whenever the ejaculation occurs, the sperm combine with liquid released by the seminal vesicles and the prostate gland and all together combine and release through the urethra.
- Generally for the sperm, it takes an average of three months from the production to mature.
- The process of sperm production is called spermatogenesis.
- The average sperm production per second is 1500 approximately and per day millions of sperm are produced in the body.
- By the end of the sperm cycle it is over, and again 8 million are produced.
- Generally averagely per ejaculation 2 to 6 ml of fluid is released and it contains up to 6 to 450 millions of sperm.
- The amount of seminal fluid does not affect the quality and the quantity of the sperm, even though the range of ejaculation liquid is about 2 to 8 ml and the average is about 3 ml and it contains approximately 300 million.

Hence, The correct answer is option (B).

Note: Generally, having the 10 million of sperm per ml or per ejaculation is usually considered as low sperm count, up to 40 million it is to lower than the average count and if it is more than 300 million, then it is high count, irrespective of the count, the quality of the sperm is a matter for the proper fertilization.
