Pregnancy tests - a magic wand that can be good news or upset. These tests detect the presence of urinary hCG (human chorionic gonadotropin), which explicitly indicates the presence of pregnancy. Pregnancy tests have become widely available in 1978, although the first such test was accurate in 80% and was placed for 2 hours.
Before the invention of this wonderful device, the most reliable test was just to wait and see. But the people and then wanted to know as soon as possible about a possible pregnancy
How do they determine pregnancy prior to 1978?
1. Ancient Egyptian pregnancy test. Wheat and barley
One of the first, if not the first pregnancy test was a test of Ancient Egypt. In 1350 BC woman urinated on the seeds of wheat and barley for several days, and if germinate wheat is considered that to be born a girl, and if it's a boy barley. If nothing has evolved, the pregnancy was not. The most interesting thing in this test was the fact that it really works. In 1963, the laboratory experiment showed that in 70 percent of cases, the urine of pregnant women can lead to germination of seeds, while the urine of non-pregnant women and men have no effect on the seeds. The ancient Egyptians were really acting is a pregnancy test with an accuracy of 70%, at least.
2. Drevnegrechisky pregnancy test. Onion
While the ancient Egyptians had urinated on the seeds, the ancient Greeks, it seems, is less understood in anatomy. Known records of Hippocrates, it became known that the Greeks used the bulb to determine pregnancy. Woman inserts her vagina bulb. They must be there all night. . If breathing woman the next morning was the smell of onions, it was thought the Greeks, was not pregnant. The idea of the Greeks, if the woman is not pregnant, the uterus is then opened and the smell of onions penetrated above the body.
In the modern world was comical incident when a young man, after drinking, put the bulb into the vagina of his sleeping girlfriend. In the morning she woke up with pain and went to the hospital, she thought, that he had cancer of the uterus, but the doctors it "cheered" ;)
3. Drevneegipestky pregnancy test number 2. Beer
Another ancient Egyptian papyrus tells of beer pregnancy test. Woman wrapped in a large piece of cloth soaked with beer. So it was left for a few hours. If the girl from the gut-wrenching smell, she was pregnant. This assumption is related to the toxicity in the early stages of pregnancy.
4. Medieval pregnancy test. Key
The collection of medical knowledge, written in the late 15th century, there is an unusual way of determining pregnancy. In order to understand whether she is pregnant, it is necessary to ask her to pee in a container. After the throw there rusty key. If after 2-3 days the rust came off with the key, then the girl is pregnant.
5. European pregnancy test. "I wrote a clairvoyant"
In 16th century Europe were popular so-called "Pee clairvoyants." These so-called experts said that they could determine whether or not a woman is pregnant by the color and characteristics of her urine. Some of them mixed urine with wine and watched. But you know, it was more like a guessing on urine.
6. Kvropeysky pregnancy test number 2. "Look into my eyes"
A doctor of the sixteenth century, Jacques Guillemeu, argued that a woman's eyes can be determined whether she is pregnant. Jacques, the author of a large and popular treatise on ophthalmology, said that in the second month of pregnancy, the pregnant woman's eyes change. For pregnant women characterized deep-set eyes with small pupils, drooping eyelids and swollen veins around the eyes. Of course, this level of divination, but during pregnancy sight of a pregnant woman can really suffer.
7. French pregnancy test. Color
Early in pregnancy, about six to eight weeks, the cervix, vagina and labia can have a bluish or purplish-red color, because the blood flow to that area. It is based on that in 1836 a French doctor. This later became known as the "sign of Chadwick," after James Chadwick, began to popularize his theory. But obviously, this is not a clear indication of pregnancy
8. French pregnancy test number 2. Rabbit
In addition to the observations of the female sexual organs, Chadwick invented the "rabbit test", which was used until the 20th century. This method is based on the use of human urine in rabbits. Even then, the composition of the urine of animals, people learned to determine pregnancy, especially the success enjoyed rabbits.
This method is based on the introduction of a small number of women in animal urine. The animal died in any case, but if the girl was pregnant, after injection into the body changes as a rabbit started at conception. But death was imminent.
9. American pregnancy test. Frog
The principle of the test and what is the pregnancy that rabbit test, but this test is better because the frog survived. In the late 1940s, scientists discovered that when the urine of pregnant women was introduced into a living toad or frog, unfortunate amphibians began to produce eggs and made it within 24 hours.
But these animal experiments stopped with the advent in 1978 of modern pregnancy tests that women use to this day.
