Natural Womanhood, an American corporation that promotes education focused on female fertility, quoted several research findings from the Education of Human Affectivity and Sexuality project of the Institute for Culture society (ICS) in an article on its blog, entitled "Women want to know: Does the Pill cause abortion?"

They specifically mention two articles that ICS researchers wrote. The first is an article published in the Journal of Clinical Nursing that is entitled, "Women's attitudes towards mechanisms of action of birth control methods: a cross-sectional study of five European countries." Authors of this article include: Cristina López del Burgo, Rafael Mikolajczyk, Alfonso Osorio de Rebellón, Tania Errasti and Jokin de Irala. The second article, published in the European Journal of Obstetrics & Gynecology and Reproductive Biology, is entitled, "Spanish women's attitudes towards post-fertilization effects of birth control methods." Authors of this article include: Cristina López del Burgo, Carmen M. López de Fez, Alfonso Osorio de Rebellón, José López Guzmán and Jokin de Irala.

The blog article, written by Gerard Migeon, the founder and CEO of Natural Womanhood, stresses that 8 out of 10 women do not know the abortifacient potential of some contraceptives and that 75% would like information on any possibility of this happening. In this regard, 3 of 10 women admit that they would not choose a contraceptive method that might sometimes cause an abortion. As Migeon claims, "While women's positions on the legal and moral question of abortion vary, most would agree that full disclosure of the risk of abortion is a basic right of women using contraceptive drugs."

44.8% of Spanish women would not use a method with post-fertilization effects

According to Migeon, hormonal contraceptives are mainly based on two mechanisms: preventing the fertilization of an egg (pre-fertilization effect) and preventing the implantation of an embryo through the modification of the uterine lining (post-fertilization effect).

In Migeon's own words, "The second mechanism is what we're concerned with here. If ovulation occurs and if the egg is fertilized by a sperm, which sometimes happens, especially with today's low-dose pills, the resulting embryo will travel to the uterus and attempt implantation. However, scientific literature shows that oral contraceptives, implants, the shot, the patch and IUDs make the lining of the uterus inhospitable to it.  It is also clearly stated in the labels of these contraceptive methods."

In the case of Spain, the article points out that only 7% of women are aware of birth control pills' possible post-fertilization effects, 80% would like to be informed about the effects any birth control might cause, and 44.8% would not use a method with post-fertilization effects.
