When the doctor attaches GyneFix to the womb, a short stinging pain can be felt. The pain is very similar to receiving a needle injection. Within a few seconds the pain sensation should ease away.
If you are very sensitive to pain, your doctor can administer a local anesthetic.
Immediately after insertion a minimal amount of blood loss is normal.
Light menstrual cramps are possible 2 to 3 days after insertion.
Heavier periods in the first few months of use are possible. After a few periods it will steadily return to normal.
GyneFix is very suitable for woman who haven’t given birth yet. Due to the frameless and flexible design, GyneFix adapts to any womb.
Do not use tampons and menstrual cups in the first 2 months following insertion.
It is advised to not engage in strenuous physical activity within the first week of insertion. After that exercise and physical activity are completely safe.
Do not have sexual intercourse in the first 14 days following insertion.
GyneFix is fitted inside the womb and is not noticeable during intercourse. The end of the surgical thread, on which the copper tubes are attached, protrude 1 to 2 cm from the cervix. Usually the thread curls up around the cervix, so that it is not noticeable.
If your partner is feeling the thread, you can ask your doctor to tuck the thread in the womb or cut it shorter.
Have a follow-up visit 4 to 8 weeks after GyneFix has been fitted.
GyneFix is a hormone-free method of anticonception, this means the natural menstrual-cycle of the body is maintained.
With GyneFix you cannot choose to delay or skip your period. If you want to affect the timing of your menstruation, then it is possible to temporarily use a hormone-based contraceptive method (eg. the Pill) in combination with GyneFix.
GyneFix 200 consists of 4 copper tubes which are attached to a length of surgical thread. GyneFix 200 is suitable for woman with an hysterometry of less than 8 cm.
GyneFix 330 has 6 copper tubes instead of 4. This design is suitable for woman with an hysterometry of 8 cm or more.
Your doctor will advise you which GyneFix is best suited for you.
Because GyneFix does not affect the hormonal balance of the body, fertility immediately returns after removal.
Copper allergy is a very rare condition.
A healthy adult body contains about 50 to 80 milligrams of copper. Copper is used by the body to produce bone and binding tissue. Because copper occurs naturally in the body, allergies are very rare.
Some people might think they are allergic to copper, but in most cases they are actually allergic to certain impurities (eg. nickel) contained within the copper. GyneFix uses medical grade copper of the highest purity (99,997% pure).

Dr Dirk Wildemeersch, MD, PhD (1944-2018) completed his medical training at the University of Ghent, Belgium, and graduated in gynecology in 1976, in South Africa.
Dr. Wildemeersch is the developper of several innovative contraceptive systems, including GyneFix, Gyn-CS, ReLARC, Femilis Cu, Femilis LNG and Fibroplant.
For more than 40 years, he was a devoted gynaecologist to his patients and dedicated a substantial part of his time to the clinical development of new IUD concepts and implant systems, originally in collaboration with a group of gynecologists from the University of Ghent, Belgium, under the name IUD-group which later became the International Study Group on Intrauterine Drug Delivery. Under Dr. Wildemeersch’ supervision, a research organization, Contrel Research, was established to manage clinical research and to continue to develop and study innovative drug delivery technologies, aimed at finding improved methods for the prevention and treatment of gynecological disorders, improvements to birth control methods, with higher levels of safety, user acceptability, compliance and quality of life of women. His main topics of research were contraception, including long-acting reversible intrauterine contraception, and intrauterine drug delivery for the treatment of menorrhagia and other gynaecological conditions including postmenopausal treatment.
His work is acknowledged by leading research organizations such as the World Health Organization (Reproductive Health Research) in Geneva and by the Population Council in New York.
Following his untimely passing in 2018, his wife, Rina Wildemeersch, has vowed to continue his mission and research.
