Rehash:
Might I quote from Margaret Sanger herself?
Woman and the New Race, 1920, Chapter X. "Contraceptives or Abortion?":
To understand the more clearly the difference between birth control by contraceptives and family limitation through abortion it is necessary to know something of the processes of conception. Knowledge of these processes will also enable us to comprehend more thoroughly the dangers to which woman is exposed by our antiquated laws, and how much better it would be for her to employ such preventive measures as would keep her out of the hands of the abortionist, into which the laws now drive her.
In every womans ovaries are imbedded millions of ovules or eggs. They are in every female at birth, and as the girl develops into womanhood, these ovules develop also. At a certain age, varying slightly with the individual, the ripest ovule leaves the nest or ovary and comes down one of the tubes connecting with the womb and passes out of the body. When this takes place, it is said that the girl is at the age of puberty. When it reaches the womb the ovule is ready for the process of conceptionthat is, fertilization by the male sperm.
At the time the ovule is ripening, the womb is preparing to receive it. This preparation consists of a reinforced blood supply brought to its lining. If fertilization takes place, the fertilized ovule or ovum will cling to the lining of the womb and there gather its nourishment. If fertilization does not take place, the ovum passes out of the body and the uterus throws off its surplus blood supply. This is called the menstrual period. It occurs about once a month or every twenty-eight days.
In the male organs there are glands called testes. They secrete a fluid called the semen. In the semen is the life-giving principle called the sperm.
When intercourse takes place, if no preventive is employed, the semen is deposited in the womans vagina. The ovule is not in the vagina, but is in the womb, farther up, or perhaps in the tube on its way to the womb. As steel is attracted to the magnet, the sperm of the male starts on its way to seek the ovum. Several of these sperm cells start, but only one enters the ovum and is absorbed into it. This process is called fertilization, conception or impregnation.
If no children are desired, the meeting of the male sperm and the ovum must be prevented. When scientific means are employed to prevent this meeting, one is said to practice birth control. The means used is known as a contraceptive.
If, however, a contraceptive is not used and the sperm meets the ovule and development begins, any attempt at removing it or stopping its further growth is called abortion.
