Ben, if you don't mind, you might read my post #248.
In addition, I did some very minor google searches regarding the use of "ZEF" and found the following:

This post will examine the current personhood status of born individuals, and zygotes, blastocysts (pre-embryos), embryos, and fetuses (
ZEF, for short), both in the US law and under international human rights law and norms. It will then discuss what we would need to find in order to change that law. It will then conclude with a more thorough examination of why granting personhood status to zygotes, blastocysts (pre-embryos), embryos, and/or fetuses is impossible without eroding the rights of women.

Biological development
Development begins with fertilization, the process by which the male gamete, the sperm cell, and the female gamete, the egg, fuse to produce a zygote. In pregnancy the 3 stages are commonly referred as
Z.E.F.- meaning Zygote, Embryo, Fetus.

No person can legally force another to donate redundant organs or even blood to save their life. Why or how can someone expect a "zygote/embryo/fetus" or
"ZEF" or baby who is not a legal person to be able to do more ("take over the uterus of the woman") to a woman than any other human can do to another?

This is a GOOD ONE From a Pro-Life Site
Foetus Latin meaning "little one" was once recognized to refer to the baby in utero. With the advent of abortion law reform, the term unborn or pre-born baby came to be used by those opposed to abortion to give recognition of the humanity of the fetus, while abortion rights activists prefer to use terms such as zygote, embryo and fetus, pre-embryo, even
"ZEF," which have a certain dehumanizing effect.
On this site…no medical term is acceptable for pre-born!

Choice in Dying Fertilization and Personhood
Any concept of personhood which confers personhood on something not capable of exercising freedom is meaningless, and by conferring this character on zygotes or embryos or fetuses (
ZEF’s), which are not capable of exercising freedom, the freedom of the woman in whom ZEF’s are present is immediately to violate the rights of that woman to her freedom to choose.
