Final answer:
Transcervical Sterilization (Essure) is a surgical procedure for female sterilization that involves placing a metal coil into the fallopian tubes to block conception. It is not a form of emergency contraception, reversible contraceptive, or hormonal method. Essure is no longer available in the United States as of December 2018.
Step-by-step explanation:
Transcervical Sterilization, commonly referred to as Essure, is a form of female sterilization. This is definitely not an emergency contraception, not a long-acting reversible contraceptive (LARC), nor a hormonal contraceptive method. Instead, it is a surgical procedure that falls under contraception and is designed to permanently prevent pregnancy. The procedure involves placing a small metal coil into the fallopian tubes via the cervix. Over time, tissue grows around the coils, effectively blocking the fallopian tubes and thereby preventing sperm from reaching an egg for fertilization.
This method of sterilization was an alternative to the more invasive tubal ligation, where the fallopian tubes are cut or tied. However, it's important to note that Essure is no longer available for implantation in the United States as of December 31, 2018, following reports of serious adverse events.
