According to every resource I can find: medline, medical-dictionary, Tabers, PDR, Merck, my AH A&P text and my PM A&P text, my Endo text, and just “fun with Google,” as I’ve been saying all along, progestins are hormones that act like progesterone, and progesterone is a progestin. The term “progesterone” is used to describe the naturally occuring hormone produced by the corpus luteum, OR any variety of synthetic progestationals–synonymous with progestins etc. Yes, I was wrong about MPA, but that was due to garbled (IMO) text in the Merck. However, MPA IS the active component of Depo-provera. To my understanding, it’s not contraceptive when ingested because of low bioavailability, ihibiting high enough serum levels etc…(for longer technical explanation describing primary and secondary metabolites, but I think I got the gist) but is extremely effective parenterally.
ALSO: I’ve looked up the directions for over 20 combo and progesterone-only OCs, and the only instructions I find are for 1st Sunday (no more than 6 days after the first day) or 1st day starts. Some have both instructions, some specify it must be started on the first day, but NONE have any “quickstart” or “whenever start” instructions indicated for regulation of cycle or contraception. Some DO have dosing differentiation when used for other therapies, but they are being used to stop abnormal uterine bleeding, and in high, frequent doses etc. I didn’t Google for that info, if there’s newer OCs out there that have such instructions, they’re not in my PDR. 58th ed…(2004) so a little outdated, but not that far back…not 14 years!
And regardless of the wording used in various books, if “the pill” is started when it should be, then it should arrest endometrium preparation at mid-proliferation, allowing it to repair, but not become ideal for implantation, and because of this, certain intergins do not form in the same abundance, theoretically making it more difficult for an embryo to implant. HOWEVER, apparently they do at a rate of up to 8% depending on the hormonal method used, progesterone-only being the least effective. So nothing is thinning out anything. The endometrium never GETS thick when one is properly using hormone BC.
Since abortifacient means: induces abortion, I don’t see how the secondary side-effect, of a medication that is essential whenever estrogens are taken therapeutically–the failure of the endometrium to properly prepare for embrionic implantation. It’s not CAUSING an embryo to expell. It’s not destroying an embryo. It’s merely keeping the endometrium thinner (which by the way is one of the biggest reasons it HELPS). I mean, THAT is the desired effect (for the most part) in treating women who are experiencing long, painful, heavy menses. And, for those who mentioned “other” hormone therapies…like what? Estrogens and progesterones that don’t come in a OC package? Even the ones that aren’t considered contraceptive are contraindicated during pregnancy, or in women who are trying, or could become pregnant.
Also: Fish are so biologically asimilar to humans well…that study just sounds silly to me. Besides, there’s no lack of warnings and contraindications etc. put out by the manufacturers of hormonal BCs. Trust me, I just read through 20-something descriptions. I don’t think methadone has that many warnings!
And with that, apparently HE decides who’s going to conceive a child regardless of what she does to prohibit conception.
