“The oviduct or Fallopian tube is the anatomical region where every new life begins in mammalian species. After a long journey, the spermatozoa meet the oocyte in the specific site of the oviduct named ampulla, and fertilization takes place.”

The government’s own definition attests to the fact that life begins at fertilization. According to the National Institutes of Health, “fertilization” is the process of union of two gametes (i.e., ovum and sperm) “whereby the somatic chromosome number is restored and the development of a new individual is initiated.”

“Human life begins at fertilization, the process during which a male gamete or sperm (spermatozoo developmentn) unites with a female gamete or oocyte (ovum) to form a single cell called a zygote. This highly specialized, totipotent cell marked the beginning of each of us as a unique individual.” “A zygote is the beginning of a new human being (i.e., an embryo).”
