Why recommend MONA LISA® IUDs?


According to the Society of Obstetricians and Gynaecologists of Canada, copper IUDs, like MONA LISA® IUDs, are 99.2% effective. During the first year of typical use*, there were 8 pregnancies per 1,000 women.

Long acting

Once inserted in the uterus, a MONA LISA® IUD provides effective birth control for 3, 5 or 10 years, depending on the patient’s choice.


MONA LISA® IUDs do not affect ovulation and, upon removal, women return to their normal fertility rates.


MONA LISA® IUDs provide effective birth control with none of the potential side effects associated with estrogen and/or progestin found in some forms of hormonal contraception (like the pill) or the synthetic hormone levonorgestrel (progestin) found in hormonal IUSs.


Clinical studies confirm the safety of copper IUDs. MONA LISA® IUDs also provide safe and effective birth control to breastfeeding mothers.

High quality

MONA LISA® IUDs have for decades been manufactured by the same specialty manufacturer in Europe that exclusively produces copper IUDs, and meets strict international standards for quality and sterility.


As there are no ongoing costs once inserted, a MONA LISA® IUD offers a budget-friendly long-term contraceptive solution. According to the Society of Obstetricians and Gynaecologists of Canada, copper IUDs like MONA LISA® IUDs have also been shown to prevent endometrial cancer. The data suggests that prolonged use of MONA LISA® IUDs have health benefits that contribute significantly towards lowering health care costs.

Emergency contraception

MONA LISA® IUDs offer effective, emergency contraception like a morning after pill such as plan B®. But unlike plan B®, which becomes less effective the longer the delay in taking it, MONA LISA® IUDs can be inserted up to 5 days after having unprotected sex.

*TYPICAL USE” of a birth control method refers to how effective the method is during actual use (including inconsistent and incorrect use). Relative efficacy of birth control can also be measured in “perfect use”, which refers to when the method is always used correctly and consistently, as directed.
