A five year old girl asked the question that every parent dreads, “Mommy, how are babies made?” The mom did her best to explain, but the daughter still looked confused.

“But what about kittens?” she asked.“Well, it is exactly the same way.” I said.“Wow!” she said excitedly, “My Daddy

can do anything!”

5. FERTILIZATION / Conception• The end purpose for the

ova and the sperm• When the sperm

penetrates the surface of the ova and enters inside.

• The 23 chromosomes from each sex cell combine and begin to multiply to begin to form a new human being!!!

During MenstruationDays 1-5

Menstruation occurs and the lining of the uterus, with a small amount of blood, leaves the body. At this time, another egg is maturing in the ovary.

The Menstrual Cycle

After MenstruationDays 6-15

The lining of the uterus repairs itself and once again prepares for a fertilized egg. Around days 13-15 an egg is released from an ovary. This is called OVULATION

The Menstrual Cycle

Before MenstruationDays 16-28

If the egg is fertilized by the male sperm cell, it embeds itself in the wall of the uterus (endometrium lining). If the egg is not fertilized, the blood vessels in the wall of the uterus shrinks and breaks down. The menstruation cycle begins again.
