Sperm Meets Egg: Week 1 To 3 Of Pregnancy

 

The due date is calculated from the first day of your last menstrual period. Conception occurs about two weeks after this day. This is only when you are considered pregnant.

Hormonal surge is controlled by the brain which causes one of the ovaries to produce an egg. If both ovaries produce an egg, you may have non-identical twins. Long finger-like projections swipe the egg into the fallopian tube.

The egg travels down the fallopian tube pushed by tiny hairs and awaits the arrival of the sperm. About a teaspoon of semen enters the vagina containing roughly 300 million sperms. Less than 100,000 sperms pass the cervix to begin their 6-inch journey to the egg.

A long wig like tail propels the sperm towards the waiting egg. Most sperms lose their way. Only 200 sperms successfully reach the egg. Fertilization then occurs when one sperm penetrates the egg combining their genetic material.

The sperm and the egg each contain 23 chromosomes holding all the information that determines your child's sex and contribute to the child's makeup including physical appearance, intelligence and personality. Whether it is a boy or a girl you do not know yet.

Within 24 hours of fertilization, the egg now called the zygote divides into two cells. The number of cells doubles about every 12 hours as the zygote continues its tract into the uterus. During this stage, if the cell separates into two different groups instead of remaining attached, you will be blessed with identical twins.

About 3 days after fertilization, the zygote has become a ball of about 32 cells resembling a miniature raspberry. A few days later, it reaches the uterus as a ball of about 500 cells surrounding a fluid-filled cavity.

On day 7, the ball of cells bores into the uterine wall in a process known as implantation. Many women have implantation bleeding at this time which occurs after 21 days before a pregnancy test could even test positive. The cells on the outside of the ball create the yolk sack and the placenta which nourishes the baby.

By 38 weeks, the fertilized egg has grown into an infant with more than 2 trillion cells.

   P POWER The Art of Leadership 5 minute read The true commander is the saviour, the messiah, the Good Samaritan. For what perfectly amounts to brotherly love and contentedness of mankind? Three elements; liberty, stateliness and prosperity. If you hand down this trifecta to your men, their fondness toward you will persevere. TABLE OF CONTENTS HIDE Clarity and Calculation Foresight and Unity Liberty, Stateliness and Prosperity Lust, Restraint and Chance The Economy of Language Clarity and Calculation You can be certain that men in great quantities can be overpowering. However, when their bravery is dismantled by a hero, anxiety makes them dizzy. And the larger the quantities, the more violent the trepidation. It can loom to such an intensity that no commander can pacify it with incentive or drive. No superior can kindle that initial belief by withdrawal. The more he attempts to reinstate their animation, the more uneasy the warriors in turn feel. Nonetheless, even within the bounds of
