The story of menstruation begins, as the motherly narrator informs us, with the pituitary gland - a gland at the base of the brain that sends hormones throughout the bloodstream that order growth. When a girl reaches an age somewhere between 11 and 17 - the average is 13 - the pituitary gland sends maturing orders to the ovaries, which in turn order the uterus to create a thickened lining, filled with watery fluids and blood. If an egg is fertilized it will remain within that thickened lining for nourishment. But if the egg is not fertilized, the body has no use for the extra nourishment, and it passes out of the body - which is the process called menstruation. The narrator proceeds to disprove taboos against bathing or exercise during menstruation. She advises that girls should keep a calendar that keeps track of the number days between periods. And she notes how good posture, healthy foods and positive attitudes can affect the menstruation cycle. Written by J. Spurlin
Here is one of those educational short films made to learn the unknown people out there about facts of life. This time the target audience is preteen girls, the fact of life is menstruation. This animated film, created by Walt Disney Pictures, apparently with some sponsoring from Kotex.
It starts with explaining how hormones make you grow and develop. With the help of animation and a female narrator it shows us how the body, especially the ovaries, uterus and vagina, work and why this all leads to menstruation. It is almost amazing, becoming the comic note here, how the subject of sex is avoided. Even the word is never mentioned although "furtilized" will pass once. I don't really know why I saw this, but since it is one of those rare short films that could give an impression of an innocent time, you might want to give it a try.
