The word(s) "pairs" appears 20 time(s) in 19 verse(s) in Quran in Abdullah Yusuf Ali translation.

(11) And Allah did create you from dust; then from a sperm-drop; then He made you in pairs. And no female conceives, or lays down (her load), but with His knowledge. Nor is a man long-lived granted length of days, nor is a part cut off from his life, but is in a Decree (ordained). All this is easy to Allah.

(12) Glory to Allah, Who created in pairs all things that the earth produces, as well as their own (human) kind and (other) things of which they have no knowledge.

(13) He created you (all) from a single person: then created, of like nature, his mate; and he sent down for you eight head of cattle in pairs: He makes you, in the wombs of your mothers, in stages, one after another, in three veils of darkness. such is Allah, your Lord and Cherisher: to Him belongs (all) dominion. There is no god but He: then how are ye turned away (from your true Centre)?

(14) (He is) the Creator of the heavens and the earth: He has made for you pairs from among yourselves, and pairs among cattle: by this means does He multiply you: there is nothing whatever like unto Him, and He is the One that hears and sees (all things).

(15) That has created pairs in all things, and has made for you ships and cattle on which ye ride,

(16) And the earth- We have spread it out, and set thereon mountains standing firm, and produced therein every kind of beautiful growth (in pairs)-

(17) And of every thing We have created pairs: That ye may receive instruction.

(18) That He did create in pairs,- male and female,

(19) And (have We not) created you in pairs,
