(Redirected from Pessaries)
Pessary[edit | edit source]
Introduction[edit | edit source]
A pessary is a contraceptive device designed to be inserted into the vagina to prevent pregnancy. It is a flexible, dome-shaped cup made of rubber or plastic that works by covering the cervix to block sperm from entering the uterus. Pessaries have been used for centuries as a method of contraception and have evolved in design and materials over time.
History[edit | edit source]
The use of pessaries as a form of contraception dates back to ancient times, with references to similar devices found in ancient Greek and Egyptian texts. Initially, various materials such as crocodile dung, honey, and cotton were used. The modern rubber or silicone pessaries were developed in the 19th and 20th centuries, providing a safer and more effective means of contraception.
Types and Materials[edit | edit source]
There are several types of contraceptive pessaries, including:
- Diaphragm pessaries: A shallow, dome-shaped device made of silicone or latex.
- Cervical cap pessaries: Smaller than diaphragms and designed to fit snugly over the cervix.
The choice between types depends on individual preference, fit, and comfort. Modern pessaries are typically made from silicone or latex, materials chosen for their flexibility, durability, and safety.
Mechanism of Action[edit | edit source]
Pessaries act as a physical barrier preventing sperm from entering the uterus. For increased effectiveness, they are often used in conjunction with spermicidal agents that immobilize or kill sperm on contact.
Usage and Effectiveness[edit | edit source]
To be effective, a pessary must be correctly inserted into the vagina before intercourse and left in place for at least 6-8 hours after. When used correctly and consistently, pessaries can be an effective form of contraception. However, their effectiveness is generally lower than that of hormonal methods of contraception.
