What is a hormonal IUD?
The hormonal IUD is placed in a woman's uterus. It's a small, highly flexible piece of plastic resembling the letter T, containing a dose ofsynthetic hormones which are released over a period of 5 years, with a contraceptive efficacy of almost 99.9%. The hormones released are progestins similar to those found in certain pills. This contraceptive will therefore have an impact on the production of the uterine mucous membrane and on uterine secretions, to prevent pregnancy through the implantation of an embryo. Levonorgestrel makes the uterine mucosa very thin. This makes implantation impossible. The IUD and periods are linked by their impact on uterine tissue.
This method of contraception is inserted by a healthcare professional. The IUD is inserted using a speculum. Insertion is generally painless. The IUD is removed by a healthcare professional, using a thread.
The hormonal IUD is an internal contraceptive, like the copper IUD, the diaphragm and the female condom.
Is there a difference between IUD models?

What are the effects of the hormonal IUD on periods ?
This contraceptive method has a direct impact on the various menstrual phases. In fact, by releasing hormones, it has an impact on the creation of the endometrium, which lines the cervix and thickens over the course of the month to accommodate a pregnancy. Like the contraceptive pill, it will potentially have an impact on bleeding at periods. While the copper IUD will increase the volume of menstrual periods, the hormonal IUD will considerably reduce them.
Little or no periods
When a hormonal IUD is inserted, women tend to experience the following periods symptoms:
- Amenorrhea, absence of menstruation
- Very light menstrual flow
- Blood loss outside the menstrual period, also known as spotting
The reason is that this contraceptive does not preventovulation, but acts on thethickness of the uterine mucosa, making it very thin. This prevents an embryo from taking hold. As the uterine tissue is thinner, there is less blood loss at periods , as there is less tissue to evacuate.
Bleeding after fitting
