'Natural Womanhood', a U.S. corporation focused on the Education on female fertility, quotation in a article on its blog, graduate 'Women want to know: does the Pill cause abortion?', several investigations of the project Education of human affectivity and sexuality'. of the Institute for Culture and Society (ICS).

Specifically, it mentions two articles by ICS researchers. The first is Women's attitudes towards mechanisms of action of birth control methods: a cross-sectional study of five European countriessigned by Cristina López del Burgo, Rafael Mikolajczyk, Alfonso Osorio de Rebellón, Tania Errasti and Jokin de Irala, and published in the Journal of Clinical Nursing. The second, Spanish women's attitudes towards post-fertilization effects of birth control methodsis signed by Cristina López del Burgo, Carmen M. López de Fez, Alfonso Osorio de Rebellón, José López Guzmán and Jokin de Irala, and published in European Journal of Obstetrics & Gynecology and Reproductive Biology.

The article, written by Gerard Migeon, founder and CEO of 'Natural Womanhood', highlights that 8 out of 10 women are unaware of the abortifacient potential of some contraceptives and that 75% would like to receive information about any possibility of this occurring. In that sense, 3 out of 10 recognize that they would not choose a contraceptive method that could, on occasion, cause an abortion. "While women hold different positions on the legal and moral issues of abortion, most agree that disclosure of the risk of abortion is a basic right of all women using contraceptive drugs," she says.

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

According to the expert, hormonal contraceptives are mainly based on two mechanisms: prevention of the fertilization of an egg (pre-fertilization effect) and prevention of embryo implantation by modifying the lining of the uterus (post-fertilization effect).

"The second mechanism is the one that concerns us here: if ovulation takes place and an egg is fertilized by a sperm, which sometimes happens, the resulting embryo will travel to the uterus and try to implant. However, the scientific literature sample that oral contraceptives, implants, injections, patches and IUDs render the lining of the uterus inhospitable. This is clearly stated in the package inserts of these contraceptive methods," notes Gerard Migeon.

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