    The Study and Analysis of Sexual Cells (Gametes) in Human from the Perspective of Quran by Hamidreza Basiri, Maryam Gohari, Seyyed Mohammad Akrami

    Published 2016-11-01
    “…In this article, after examining the verses related to gametes, it was concluded that the term »maa«  refers to expressing absolute or specific features, the term »manie«  and its derivatives and the term »solaleh«  refer to gametes (sperm and ovule), but the term »notfeh« is absolutely related to gametes in some verses, and indicates the fertilized ovule (zygote) in other verses. The term »notfeh«with a special feature reveals zygote sperm as well as ovul, and accurate scientific points about gametes can be understood through the article.…”
