Question

If the sperm count of a human male is 200 million per ejaculate, then how many sperms should have at least normal shape, size and vigorous motility for normal fertility?
A.120 million
B.48 million
C.80 million
D.60 million

Answer 1

Hint: The sperm cells are the male gametes which are produced in the male testicles. Around 1000 sperm are produced every second. During ejaculation men release sperm mixed with seminal fluid which is called semen. 1ml of semen contains around 100 million sperms.

Complete answer:
Sperms are the male reproductive cells present in the ejaculate. Normal sperm count of a healthy male is around 48million to 200 million per ejaculate. In a normal ejaculation, around 4-6 ml of semen is released. Sperm count refers to an average number of sperms released in an ejaculate. Normal sperm count is around 150 million sperm produced in 1 ml of ejaculate.
Lower sperm count, abnormal shape or weak sperms is a test for male infertility. An ejaculate must have 60% of the normal moving and having normal shape and size. So in 200 million of ejaculates at least 120 million of sperms should have normal motility, shape and size.

Hence, the correct answer is option (A)

Note: Abnormal sperm count is caused due to various factors like lifestyle or medical conditions like blockage to the passage of sperms, several diseases, hormone imbalances, genetic factors etc. The problems can be cured by the help of hormonal therapy or removal of blockages. Chromosomal abnormalities can lead to permanent infertility.
