ehkäisyrenkaana

Ehkäisyrengas is a Finnish term referring to a vaginal ring, a type of hormonal contraceptive. It is a flexible ring made of plastic and silicone, approximately 5.4 centimeters in diameter, which is inserted into the vagina by the user. The ring releases hormones, estrogen and progestin, into the bloodstream at a steady rate. These hormones prevent pregnancy by inhibiting ovulation, thickening cervical mucus to prevent sperm from reaching the egg, and thinning the uterine lining.

The ehkäisyrengas is typically worn for three weeks, followed by a one-week break during which a withdrawal bleed occurs. A new ring is then inserted. It is a highly effective method of contraception when used correctly, with a failure rate of less than 1% per year. The hormones are absorbed through the vaginal lining, bypassing the digestive system, which can be advantageous for individuals who experience gastrointestinal issues or have difficulty with pills.

Like other hormonal contraceptives, ehkäisyrenkaat carry potential side effects, which can include nausea, headaches, breast tenderness, mood changes, and an increased risk of blood clots. It is important for individuals considering this method to discuss their medical history and any concerns with a healthcare provider to determine if it is a suitable option. The ehkäisyrengas does not protect against sexually transmitted infections.
