Question

For normal fertility the sperms should have

• A. at least 30 per cent sperms must have normal shape and size and at least 30 per cent of them must show vigorous motility
• B. at least 60 per cent sperms must have normal shape and size and at least 40 per cent of them must show vigorous motility
• C. at least 20 per cent sperms must have normal shape and size and at least 30 per cent of them must show vigorous motility
• D. at least 10 per cent sperms must have normal shape and size and at least 20 per cent of them must show vigorous motility

Answer 1

The correct option is B at least 60 per cent sperms must have normal shape and size and at least 40 per cent of them must show vigorous motility

For normal fertility at least 60% sperms must have normal shape and size and 40% of them must show vigorous motility.

The most common test of a man’s fertility is a semen analysis. This measures many features of the sperm and semen (the fluid in which the sperm are contained). The most important of these are the number of sperm (sperm count), motility of the sperm (percentage of moving sperm), morphology of the sperm (percentage of normally shaped sperm), and the volume of fluid. Higher amounts of abnormally shaped sperm has been associated with infertility in some studies
