A conceptus (from Latin: concipere, to conceive) is an embryo and its appendages (adnexa), the associated membranes, placenta, and umbilical cord; the products of conception [1] or, more broadly, "the product of conception at any point between fertilization and birth."
Human fertilization is the union of an egg and sperm, occurring primarily in the ampulla of the fallopian tube. [1] The result of this union leads to the production of a fertilized egg called a zygote, initiating embryonic development.
However, some human developmental biology literature refers to the conceptus and such medical literature refers to the "products of conception" as the post-implantation embryo and its surrounding membranes. [34] The term "conception" is not usually used in scientific literature because of its variable definition and connotation.
The term "conception" refers variably to either fertilization or to formation of the conceptus after its implantation in the uterus, and this terminology is controversial. The zygote will develop into a male if the egg is fertilized by a sperm that carries a Y chromosome , or a female if the sperm carries an X chromosome . [ 5 ]
Biological and legal requirements [ edit ] In order for human reproduction to be achieved, an individual must have undergone puberty first, requiring ovulation in females and the spermarche in males to have occurred prior to engaging in sexual intercourse or achieving pregnancy through non-penetrative means.
Conception commonly refers to: Concept, an abstract idea or a mental symbol; Conception (biology), fertilization of the ovum; Conception may also refer to: Entertainment
Trump's executive order declares sex as "an individual's immutable biological classification as either male or female" and states that "gender identity" cannot be included in the definition of ...
In biological terms, the development of the human body entails growth from a one-celled zygote to an adult human being. Fertilization occurs when the sperm cell successfully enters and fuses with an egg cell (ovum). The genetic material of the sperm and egg then combine to form the single cell zygote and the germinal stage of development commences.
