STS 557 as an interceptive in rodents and baboons

Appreciation for Analysis of how Levonorgestrel Works and Reservations with the use of Meloxicam as Emergency Contraception

“…"Plan B, Barr Laboratories, Inc.," 779-781). Moreover, Russian researchers reported precisely this same " [i]nterceptive" efficacy in baboons (Oettel et al 1980). This is the third example of a Plan B postfertilization effect.…”

“…Thus, the phrase "emergency contraception" is actually a double (and expanding) lie. It is not a pregnancy that is being prevented, but the birth of a baby, by his or her elimination at the pre-implantation embryo stage with traditional strategies such as DES, Yuzpe or Plan B via interceptive abortions (Oettel et al 1980). Later, EC was expanded to include contragestive abortions via RU-486 or ella taken in the middle to even late embryonic period, or the insertion of an IUD on day 28 (or beyond).…”

“…The Russian baboon researchers were much more forthcoming (and scientifically precise) about the LNG mechanism of action. They noted, "Among primates the baboon is one of the best available species as a model for human implantation.…It has been demonstrated that post-coital levonorgestrel has a good interceptive effect in women" (Oettel et al 1980). 4 See note 3 above.…”

The Breast Cancer Epidemic: 10 Facts

“…The clinical pregnancy rate was reduced from 92% in the control group of baboons (11 of 12) to 10% (2 of 20) for those receiving LNG—an 89% reduction, which is exactly the FDA approved manufacturers reported efficacy rate for Plan B. These WHO funded researchers accurately described this action as an interceptive effect, which they defined as processes that “reliably interfere with some of the procedures preceding implantation” (see Oettel et al 1980). …”

Postcoital contraception

“…STS 557 exhibits an anti-implantation effect in baboons with a single dose of 0.4 mg administered 3-6 h after the onset of mating [71]. Two dose regimens have been in use in the German Democratic Republic.…”
