Barrier Strategies of Contraception

The barrier solutions of birth regulate work by avoiding the sperm from achieving the egg. The concept of inserting something into the vagina to avoid being pregnant is not new. These units ended up named pessaries and they ended up utilised by the historical Egyptians.

Pessaries were talked about as early as 1850 B.C. in the Petri Papyrus. The components then was a mixture of crocodile dung and honey which was put in the vagina prior to intercourse.

“Apparently, this combination not only acted as a barrier to sperm, but experienced some wide spermicidal results. If a convenient crocodile was not available, elephant dung could be used,” mentioned Dr. Niels Lauersen, a diplomate of the American Board of Obstetrics and Gynecology and Steven Whitney in “It is really Your Physique: A Woman’s Guidebook to Gynecology.”

Various formulas of pessaries ended up utilised in the course of the globe. Elephant dung and honey was the chosen combina¬tion in India and Africa. In Persia during the 10th century, pessaries ended up manufactured of combined rock salt and an oily substance.

The most well-known pessary, even so, was invented by Walter Rendell, a London chemist who lived in the late 1800s. Looking at how numerous men and women endured from the stress of having much too numerous small children, Rendell developed a pessary that contains quinine which he dispersed freely to consumers at his pharmacy.

“The success of this new pessary exceeded his expecta¬tions. Requests ended up logged so speedily that the pessary was promoted commercially in 1886. By the turn of the century, the merchandise was a finest seller during the planet. In reality, till the 20th century, quinine was the only recognized spermicide which could be used with complete basic safety,” Lauersen and Whitney added.

With the reputation of pessaries, new formulas ended up developed applying significantly less irritating substances. Present-day barrier methods of contraception consist of the diaphragm, vaginal sponge, condom and cervical cap. These are frequently applied with each other with chemical obstacles these as creams, jellies, foams and suppositories. Let us take a look at them one particular by a person.

DIAPHRAGM AND CERVICAL CAP
The diaphragm is a molded rubber cap which blocks sperm as it covers the cervix and the back of the vagina. It should be inserted for each individual act of intercourse and remaining on for six to eight hours afterward.

A more compact variation of the diaphragm is the cervical cap which covers only the cervix but performs the exact way. Compared with the diaphragm, however, this system ought to be fitted by a medical professional. Women may well uncover it complicated to do the very same mainly because the cap ought to be inserted deep within just the vagina.

The initial real diaphragm was created by Aetius of Amida in the 6th century employing the fruit of the pomegranate tree. After getting rid of the seeds and pulp of that fruit, Aetius told gals to insert the hollow conclusion into the vagina before intercourse.

In 1883, Dr. Frederick Wilde, a German medical professional, described how a rubber cap could block sperm, but it was Dr. Wilhelm Mensinga, one more German, who popularized the technique. (Subsequent: Shortcomings of diaphragms.)
