IVF risks

Like any medical treatment, infertility treatment has its pitfalls and risks. Fortunately due to the advances whichthere have been made particularly in the treatment of infertility over the last 20 years, the complications of this therapy are minimal.

Hyperstimulation (Ovarian hyperstimulation Syndorome – OHSS)
In connection with hormones, there’s a risk of hyperstimulation (excessive stimulation) of the ovary – Ovarian hyperstimulation Syndrome – OHSS. The main characteristics of OHSS are painful ovarian enlargement, accumulation of fluid in the abdomen (sometimes in the chest), nausea, vomiting, dehydration and the risk of thrombosis (potentially very serious).

OHSS mostly occurs in the last week of the cycle in which the retrieval of eggs is done, or even a few days after the embryos are transferred back into the uterus. Everything would be simultaneously affected by a succeeding pregnancy, so if there is a serious risk of OHSS, we recommend freezing all your embryos for a transfer and the postponement of the time when it comes to calm the situation of the ovaries.

Our medicine knows effective methods by which symptoms and difficulties can effectively reduce and monitor up to their abandonment (infusion, aspiration of fluid from the abdominal cavity …). This care can provide you with our facility that has experience with this treatment.

Cancer illnesses 

Long-term cancer risk for IVF cycle is still unknown, but in general it seems to be minimal. It is believed that estrogen sensitive tissues such as breast, uterus, cervix and ovaries may be influenced by long-term IVF treatment.

However, studies in women undergoing hormonal therapy, it has not been showing. Infertility may be linked to cancer due to the fact that pregnancy should have protective effects against certain types of cancers, particularly ovarian cancer.

Hormones may accelerate the growth of existing cancer cells in some tissues. Therefore we recommend that before embarking on IVF treatment, breast examination, medical gynecological examination and cervical smear cytologic (oncologic). In addition, you should be sure that you are immune to rubeolle (rubella), and is also reasonable to start taking vitamins, such as folic acid.

Complications during egg collection
In rare cases, complications may occur during the collection of eggs – bleeding, infection risk, the risk of rupture of the follicle, the risk of injury to structures in the pelvis or abdomen.

Pregnancy after IVF

Congenital malformations after IVF
Pregnancy after IVF does not increase the incidence of malformations in fetuses as compared to the general population.

Multiple pregnancies after IVF
For assisted reproduction it is common the formation of multiple pregnancy (more common than in the case of natural pregnancy). But the twins are attached considerable risks for both the mother and the embryo.

Precisely for this reason, in Sanatorium Helios, maximum 1 embryo is transferred, but this does not mean that the IVF is excluded occurrence of identical twins. In some rare cases, with two embryos there were obtained even triplets.
After IVF is about 2% risk of ectopic pregnancy compared with 1% risk in the general population. The risk increases in women with partially damaged fallopian tubes (e.g. after inflammation).
