Results, reported to European IVF Monitoring (EIM) 

Year: 2019

Success Rates Explained

Success rates represent an average result (i.e. the experience of the program for groups of patients). While such statistics do not necessarily reflect what your experience will be, they are a means of evaluating a program’s success.

We submit our annual IVF treatment results to the European Society of Human Reproduction and Embyology (ESHRE). Unfortunately, the process of reporting involves an inherent two to three year lag from the time of reporting to actual publication. 

According to WHO-ICMART definition, INITIATED cycle is a cycle in which the woman receives specific medication for ovarian stimulation or in which cycle monitoring is carried out with the intention to treat, irrespective of whether or not follicular aspiration is attempted in an ovarian stimulation cycle or whether egg(s) or embryo(s) are thawed or transferred in a Frozen Embryo Transfer (FET) cycle.

Number of treatments, pregnancies and deliveries

1. In case of mixed IVF and ICSI cycles (IVF/ICSI), reported as ICSI

b Excluding PGD and ED (Egg donation)

c PGD and PGS. For initiated cycles & aspirations, included both irrespective of whether or not an embryo transfer was performed.

d In egg donation, initiated cycles and aspirations refer to the donor, whereas transfers, pregnancies and deliveries to the recipient. Fresh cycles relate to completely fresh material, FER relates to fresh oocytes but with frozen embryo replacement and FOR relates to frozen oocytes 

e NA

1. Those for fertility preservation or social freezing excluded.

g The WHO/ICMART definition of clinical pregnancy used: A pregnancy diagnosed by ultrasonographic visualization of one or more gestational sacs or definitive clinical signs of pregnancy. For the purpose of MAR/ART registries, in addition to intrauterine pregnancy it includes clinically documented ectopic pregnancy.

1. Deliveries include those resulting in a live birth and/or stillbirth, and start at 22 weeks of gestational age.

Results by women’s age and ART technique

Number of cycles (aspiration for IVF or ICSI, thawing for FER and transfers for ED) in specific age groups in relation to treatment. 

* In case of mixed IVF and ICSI cycles (IVF/ICSI), reported as ICSI

• In ED, age refers to recipient, not to donor, and all ED cycles have to be included (fresh transfers, FER and FOR)

Complications to treatments and foetal reductions

Complications with hospitalization

OHSS definition:

Grade 3

• Abdominal distension and discomfort (grade 1)
• plus nausea, vomiting and/or diarrhoea, ovaries 5-12cm
• plus ultrasonic evidence of ascites (grade 3)

Grade 4 : Grade 3 + clinical evidence of ascites and/or hydrothorax or dyspnoea 

Grade 5 : All above plus haemoconcentration, coagulation abnormalities, diminished renal perfusion 

Results by number of transferred embryos

   a / All IVF, ICSI and IVF/ICSI fresh cycles

b / All FER cycles (coming from IVF, ICSI and IVF/ICSI with own oocytes)
