Lara Dimitrijevic and Andreana Dibben tell us that the ‘morning-after pill’ is not about abortion (Interview, The Sunday Times of Malta, June 19). They are wrong.

What is an abortion? It is the killing of a human being in his or her mother’s womb.

I will try to explain what happens in the womb in layman’s terms. In human fertilisation, two cells, an ovum (female gamete) and a sperm cell (male gamete), combine to form a single cell called a zygote.

This one cell, following rapid cell division, develops into the blastocyst, which comprises 200 to 300 cells. The blastocyst will attach itself to the lining of the uterus. The blastocyst forms the embryo. In IVF, the embryo is considered to be a human being.

Now, doctors tell us that sometimes the ‘morning-after pill’ does not allow the blastocyst to attach itself to the lining of the uterus. If this happens, it is flushed out of the body and the embryo, that is, the human baby, will die. This is called an abortion. Therefore, the ‘morning-after pill’ is about abortion after all.
