BackgroundDelayed childbearing in European countries has resulted in an increase in the number of women having children later in life. Thus more women face the problem of age-related infertility and cannot achieve their desired number of children. Childbearing postponement is one of the main reasons for the increasing use of assisted reproductive technology (ART) and conversely, the latter may be one of the factors contributing to the rise in female childbearing age. The research goal of our article is to evaluate the demographic importance of ART increased use and to examine its impact on both the fertility rate and birth timing.MethodsComparative analysis based on demographic and ART data collected by the European IVF-monitoring (EIM) Consortium for the European Society of Human Reproduction and Embryology (ESHRE).ResultsMost countries with a higher total fertility rate (TFR) also registered a higher number of treatment cycles per 1 million women of reproductive age. Despite the positive relationship between the postponement rate and the demand for ART among women aged 35 and older, the highest share of children born after ART was not found in countries characterized by a “delayed” fertility schedule. Instead, the highest proportion of ART births was found in countries with fertility schedules concentrated on women aged between 25 and 34. Accordingly, the effective use of ART can be expected in populations with a less advanced postponement rate.ConclusionsART can have a demographic relevancy when women take advantage of it earlier rather than later in life. Furthermore it is suggested that the use of ART at a younger age increases women’s chance of achieving their reproductive goals and reduces the risk of age-related infertility and failed ART. Based on a demographic approach, reproductive health policy may become an integral part of policies supporting early childbearing: it may keep women from delaying too long having children and increase the chance of diagnosing potential reproductive health problems requiring a timely ART application.

In 2012, the Czech Republic established the women's age limit for access to assisted reproduction techniques at age 49 years. In this paper, the acceptability of this age limit from the children's perspective in the Czech Republic is assessed. Although the necessity of balancing the interests of parents and children is acknowledged, little research has taken children's interests into account. We have attempted to map out 'children's interests', asking older children and adolescents (aged 11-25 years) how old they would prefer their parents to be: Czech respondents would prefer to have younger parents. This finding is consistent with the optimal biological childbearing age rather than with the current postponement to a later age. So far, assisted reproduction techniques have been largely regarded as a medical treatment justifying the current women's age limit of 49 years. Had the children's perspective been taken into account, this age limit might have been lower than 49 years. We propose that reproductive health policy should adequately reflect multiple perspectives as an integral part of a multi-layered support system of a society.
