Delay of motherhood and its consequences

Did you know that the age at which women are mothers in Spain has reached the historical figure of 32 years and women only have 1.33 children? According to data from the Natural Population Movement of the National Institute of Statistics, only 8.8 children are born per thousand inhabitants, and in the first half of 2017, INE data collected a record of 187,703 births, a 6.3% less than in the same period of the previous year.

The employment situation, the economic uncertainty, the development of the professional career or the lack of a stable partner are the main factors that contribute to this delay of motherhood and, in turn, to the fact that the number of children per couple has also been seen decreased compared to previous periods.

The delay of motherhood also brings about the decrease in fertility, especially in the case of women, since it decreases after the age of 35. According to statistical data, from that age, the chances of pregnancy are reduced by half, and from the age of forty, they are reduced to 10%. This situation has caused an increase in the number of babies born through fertility and assisted reproduction treatments. In addition, techniques for the preservation of fertility are increasingly popular, which consist in preserving the ovules of the woman during her most fertile age for later use, thus preventing the effects of the passage of time.

Although the difficulty of having children increases after the age of 35, it also has its advantages, since the women who live this experience agree that the maturity acquired over the years is an added value when it comes to taking care of children.

If we find ourselves in this situation, it is convenient to bear in mind that assisted reproduction techniques or treatments are more convenient. For example, artificial insemination, which is one of the main fertility techniques, has a pregnancy rate in women aged 40 or older of 10.4% per cycle. In vitro fertilization, meanwhile, has a pregnancy rate with oocytes in women aged 35 to 39 years of 30.3% per cycle.

With the technique of oocyte donation, the pregnancy rate in women who are in the age range of 35 to 39 years is 50.7%. In the event that the technique chosen is embryo donation, it is advisable to know that the rate of pregnancy by defrosting in women ranging from 35 to 39 years is 38%. Finally, among the most commonly used techniques, vitrification by oocytes,

whose pregnancy rate by devitrification of own oocytes is 38.9%, should be emphasized.

All these data can be very helpful when making the decision to face a fertility treatment or assisted reproduction. Feeling confident and with the courage to face this new stage is key so that everything goes as expected.
