The importance of immediate contraception

Within 3 weeks after the birth, a non-breastfeeding woman can be fertile again, without having had her first menstruation. The ideal time to evaluate the patient’s future contraceptive needs and to discuss the individual benefits and risks is close to birth since it may be one of the few opportunities when she is in contact with medical services and acutely aware of the importance of contraception in future family planning.

GYN-CS®: Immediate Post-placental contraception

Verhütung nach Plazentageburt

More than 30 years ago, an article titled “Immediate postplacental IUD insertion: The expulsion problem” was published. The authors had extensive experience with the use of IUDs (both vaginal and caesarean), having used more than 2600 IUDs between 1974 and 1983 [1].

They concluded that “IPPI insertion,” postplacental contraception, meets the basic requirements of any contraceptive method: easy insertion, safety, and high efficacy. But most of all, it enables contraceptive decisions at a time when the patient’s consciousness is highest. IUD insertion immediately after birth does not increase the risk of infection or uterine perforation, has no effect on uterine involution and/or resumption of menstrual activity, and has no negative impact on lactation. So far, however, there has been a major problem with postplacental-related contraception: a much poorer retention of the IUD [2].

High rates of expulsion and displacement with post-placental IUDs

Low expulsion rates of GYN-CS®

Numerous studies in recent years confirm the problem of post-placental contraception: rates of expulsion of up to 40% or more (excluding the rates of dislocation). [3] A comparative WHO study had to be terminated prematurely because “the given expulsion index was exceeded after only six months”; after one year, the rates of expulsion were 41%, 44% and 35% for different IUDs. [4] The clinical and societal benefits of post-placental contraception are clear, but current methods are considered by many to be unacceptable for general use. High rates of expulsion can also affect the economics of the method. [5]

The innovative GYN-CS® is developed as a solution for the high expulsion and displacement rates associated with traditional IPPI. The GYN-CS® inserter is specially designed and certified for post-placental use after a caesarean birth. GYN-CS® takes into account timing, uterine compatibility, and several other clinical complexities.

A major benefit of this technique is the complete visualization and immediate access of the physician to the uterus during caesarean section. The method consists of the precise placement and fixation of a tiny anchoring knot in the fundus of the uterus immediately after the birth.

My name is Hazal Kutlucan, MD. I started inserting GYN-CS in 2018 and since then I have had a lot of experiences with the insertion and feedback of patients. Contraception is extremely important to prevent unintended pregnancies and early contraception following caesarean delivery is a great opportunity for women’s health. GYN-CS is an innovative contraceptive technology which requires a short learning curve for physicians and immediately provides reversible, highly effective contraception following caesarean delivery. Minimizing the incidence of undesirable, short interval pregnancies is possible with maximized use of the system.
