Any woman can access IVF as long as her ovaries function normally. Because of this, we must speak of biological age rather than ‘chronological age’. From 40 years onward, the quantity and quality of eggs produced by the ovaries diminishes considerably. This situation is accentuated the closer the woman gets to menopause. Therefore, the maximum age would be when the ovaries cease to function, which in most women coincides with the onset of menopause.
In this treatment, we transfer one or two embryos to the woman’s uterus, and in exceptional cases, three. Therefore, the probabilities of a multiple pregnancy, although low, are higher than with a natural conception pregnancy.
The hormonal stimulation treatment lasts around 8 days. The complete IVF treatment, from the first day of the period, until the embryo transfer, including hormonal treatment, takes a maximum of two weeks.
Approximately 900€ for the complete treatment. This quantity can diminish or increase slightly depending on the duration of the hormonal treatment. In some regions, the administration pays the cost of the medication.
The number of eggs obtained depends on the response of the ovaries. In women with low response, we obtain fewer than five eggs; in women with a normal response, between 5 and 15, and in hyper-responsive women, we obtain more than 15 eggs. When it comes to the number of embryos, it is ideal to obtain at least four with the sufficient quality for us to transfer two fresh, and if necessary, another two frozen in the future.
Two avoid a large scale multiple pregnancy. Also the law only allows a maximum of three embryos to be transferred. At our centre, we advise to transfer only one or two embryos and only in exceptional cases do we transfer three embryos.
They are frozen. Having frozen embryos allows us, if the pregnancy is not obtained with the fresh embryos, to carry out a second embryo transfer, a new chance at pregnancy without having to go through all the steps of another In vitro Fertilization. If pregnancy is obtained, the remaining embryos are kept frozen until the couple decides what to do with them.
If a couple does not use their frozen embryos, they must go to the centre to decide what is done with the embryos according to the Assisted Reproduction Law in force.
Not with the transfer alone. However, if we do not have frozen embryos, the chances of obtaining pregnancy are limited to the transfer which is carried out with fresh embryos. But the more frozen embryos we have, the more cryotransfers can be carried out, which considerably increases the chance of getting pregnant
