Answer :

Please mark my answer as the brainleist.

Single ejaculation of semen has 20,000,000 to 40,000,000 sperms. But only one or two sperms go to the oviduct fertilise the egg to form zygote .

It forms embryo that forms an individual. It is the sperm in the semen that are of importance , and there fore semen quality involves both sperm quantity and quality.
