Human fertilization is the union of a human egg and sperm, occurring in the ampulla of the fallopian tube. The result of this union, leads to the production of a zygote cell, or fertilized egg, initiating prenatal development. Scientists discovered the dynamics of human fertilization in the nineteenth century.

Fertilization ( British English spelling: fertilisation) is when a male's sperm enters a female's ovum (or "egg"). Fertilization is also called conception. Biologists call a fertilized egg a zygote. A zygote grows into an embryo . Fertilization occurs in animals, including humans and birds, in plants, fungi, protists, in fact all eukaryotes.

- Internal fertilization is the union of an egg and sperm cell during sexual reproduction inside the female body. Internal fertilization, unlike its counterpart, external fertilization, brings more control to the female with reproduction. For internal fertilization to happen there needs to be a method for the male to introduce the sperm into the fema...

In vitro fertilisation (IVF) is a process of fertilisation where an egg is combined with sperm in vitro ("in glass"). The process involves monitoring and stimulating a woman's ovulatory process, removing an ovum or ova (egg or eggs) from her ovaries and letting sperm fertilise them in a culture medium in a laboratory. After the fertilised egg undergoes embryo culture for 2–6 days, …

Iron fertilization is the intentional introduction of iron to iron-poor areas of the ocean surface to stimulate phytoplankton production. This is intended to enhance biological productivity and/or accelerate carbon dioxide (CO 2) sequestration from the atmosphere. Iron is a trace element necessary for photosynthesis in plants.

Apr 28, 2017 · Fertilization Definition Fertilization is the process by which male and female gametes are fused together, initiating the development of a new organism. The male gamete or ’sperm’, and the female gamete, ’egg’ or ’ovum’ are specialized sex cells, which fuse together to begin the formation of a zygote during a process called sexual reproduction.
- https://en.wikipedia.org/wiki/Artificial_insemination
From Wikipedia, the free encyclopedia "IUI" redirects here. For other uses, see IUI (disambiguation). Artificial insemination ( AI) is the deliberate introduction of sperm into a female's cervix or uterine cavity for the purpose of achieving a pregnancy through in vivo fertilization by means other than sexual intercourse or in vitro fertilisation.
