|
|
The notion that life starts at conception runs counter to federal law — as well as the medical community's consensus — which recognizes pregnancy as beginning with the implantation of a fertilized egg in the uterus.
|
|
Rather, it did so because certain forms of birth control, including Plan B, also known as the "morning after pill," could be considered an abortifacient because it prevents implantation of an already fertilized egg.

|
|
Mike Moon proposed a bill called the Right to Due Process Act that would change current state legislation to state that the "life of each human being begins at fertilization," extending the constitutional rights of a person to a fertilized egg.
|
|
And, depending on the wording, this kind of draconian legislation could even make certain kinds of birth control illegal — like IUDs, because they prevent implantation of a fertilized egg (which, remember, by someone's definition is a person deserving of civil rights).
|
|
In the past, religious groups have argued that life begins at conception, so they don't want to cover IUDs and emergency contraception like Plan B since those birth-control methods can prevent a fertilized egg from implanting in the uterus.
|
|
Fallopian tube removal is a common treatment for ectopic pregnanciesSince a fertilized egg is unable to develop outside of the uterus, it has to be removed along with any damaged tissue to prevent damage to the person&aposs reproductive system.
|
|
This position would not only criminalize abortions in the case of rape and incest but would prohibit the use of contraceptive methods that are understood to prevent the uterine implantation of a fertilized egg like the intrauterine device and the morning-after pill.
|
|
The method, known as endometrial scratching, involves taking a flexible tube that lets gynecologists collect tissue samples in the uterus and using it to create a small scratch in the lining of the uterus a month or so before a fertilized egg is transferred.
|

|
|
Once you&aposve conceived, the body begins to produce hCG as soon as a fertilized egg implants into the uterine wall, and it typically takes another 8 to 14 days before the hCG levels rise enough to be detected by an at-home pregnancy test.
|
|
In those rare cases when the sperm has already met its egg by the time a copper IUD is inserted, some researchers think a copper IUD may instead prevent implantation by making the uterine lining less hospitable to a fertilized egg, Mario Ascoli, PhD, tells Vox.
|
|
According to Planned Parenthood, some women may prefer the abortion pill because it's more private and many feel that it's "less invasive" than the alternative, a medical procedure in which the cervix is dilated and the endometrial tissue as well as the fertilized egg is aspirated.
|
|
We have guides on miscarriage, stillbirth (far less common and incredibly heartbreaking), ectopic pregnancy (when a fertilized egg lands somewhere other than the uterus, also rare), sudden infant death syndrome (SIDS) and a beautiful essay from Amber Scorah about having a child after losing a child.

|
|
Both Americans United for Life and Susan B. Anthony List believe that copper IUDs and emergency contraception cause abortions, which medical experts say is not the case; they can prevent ovulation, prevent fertilization, and, in some cases, the copper IUD can prevent a fertilized egg from implanting in the uterine lining.
|
|
The argument that only a woman's body is at stake doesn't work: from conception, a pregnancy involves at least distinct bodies — that of the fertilized egg which contains a distinct and new blend of DNA (from mother and father), all that is needed to become a baby, and that of the mother.
|
|
Details: The Illinois bill, or Reproductive Health Act, states that a "fertilized egg, embryo or fetus does not have independent rights" and repeals Illinois's 1975 abortion law, thereby eliminating criminal penalties for physicians who perform abortions and other restrictions on facilities where abortions are performed and provisions for waiting periods or spousal consent.
|
|
Correction 1/3/18: This post has been corrected to show that emergency contraception does not prevent implantation of a fertilized egg, it prevents fertilization of the egg, either by delaying or preventing the release of an egg from the ovaries or making it more difficult for sperm to reach an egg.
|
|
Conception requires four events to unfold perfectly: An ovary must release an egg; a sperm must reach and fertilize that egg; the fertilized egg must then travel through a woman's fallopian tube and into her uterus; and finally, it must remain in the uterus, anchored in place, as it grows into a healthy fetus.
|
|
And since about half of miscarriages happen shortly after a fertilized egg is implanted, and occur at roughly the same time a woman would expect her period, many women could be having a miscarriage and not even know it — and thus, technically be violating the law if they didn't cremate or bury the resulting tissue.
|
|
There, a fertilized egg was pierced with a glass needle and injected with the necessary ingredients for overriding the random chance of inheritance: the molecular "scissors" used in Crispr engineering, a guiding molecule that tells it where to cut, and a promoter to activate the scissors in the right tissues (see "How to Kill Off a Species, Nicely").
|
|
Ishee plans to use the gene-editing technique CRISPR to correct the single errant nucleotide that causes the condition, reversing the mutation to turn a T in the genetic code back into the correct G. Then he'll use a technique called sperm-mediated gene transfer, which will allow him to transfer his engineered Dalmation DNA to a female Dalmation, resulting, he hopes, in a fertilized egg that'll produce hyperuricemia-free pups.
