Some Basic Biology (as regards Human Reproduction)-
The Gametes:
Spermatozoon- average male orgasm produces nearly 100MIL live wiggly tadpole shaped microscopic-sized sperm.
Sperm lucky enough to enter a vagina engage in a race to the Fallopian tube in a quest to fertilize Ova. Most of the sperm die in the process. Success creates a fertilized Ovum and a Zygote. In the course of roughly two weeks, the Zygote germinates by a process known as mitosis and becomes an Embryo for about eight weeks, then a fetus until birth as an infant. Time from conception until full term birth averages about 40 weeks.
Gender usually determined by sex chromosomes-
Woman: XX; from puberty to menopause, experience monthly menstrual periods, producing ova between each period.
Male: XY
Each sperm: either X or Y; the sperm generated by a male that fertilizes the Ova determines the sex of the infant. Of course, intersex anomalies sometimes occur.
Discussion often divides a full term pregnancy into three 3 month trimesters. I personally do not know a single person who advocates for the Right to Abort a healthy fetus during the last trimester.
Fetal development is how a fetus grows during pregnancy. It begins at conception and ends at birth. Many changes occur to the fetus and the pregnant person in this time.

Some Pro Life Advocates frequently resort to describing abortion as murder or homicide. IMO, the current Conservative Majority on the USSC poses an alarming Nationwide concern to personal freedom, health, welfare and pursuit of happiness.
