Female Factor

Motherhood at the age of 45?

The age of our patients is continuously increasing and we often hear the following question:

“Is it still possible to become pregnant over 40?

The answer is: “Yes, but maybe a different way than you imagined.” Assisted reproductive medicine in Spain is advanced and the laws are more flexible than in other countries. Women can undergo fertility treatments until the age of 50. In most cases, after 43, women will need donor eggs and many times they find it difficult to accept.


IVF Success rates with your own eggs

What do pregnancy success rates depend on? For the woman, the three most important factors are age, AMH and ovarian reserve. For the man, sperm quality and age.

When undergoing IVF with their own eggs, women under 35 years of age achieve pregnancy rates of 50-60% women between 35 and 40 years of age about 40%-50% and women between 40 and 43 years about 10%-15%. After 43 it is very difficult to become pregnant with your own eggs, the pregnancy rate is then below 10%.

Despite these sobering figures, many patients find it very difficult to give up hope of becoming a mother with their own eggs. It is often incomprehensible to patients that an athletic and healthy woman over the age of 43 can no longer become a mother. However, even if you are still feel young and are in good shape of your life, your eggs determine the quality not your well-being.

When is egg donation recommended?

Egg donation is recommended when it is clear that a woman cannot achieve pregnancy with her own eggs. This can be because of many reasons, but most frequently it is due to age. At fertility clinics, pregnancy can usually be attained with the patient’s own eggs up until 42 or 43, but after this age, pregnancy is rarely achieved. At ProcreaTec and in Spain in general, egg donation is performed up until 50. In contrast to egg quality, age usually does not affect the uterus so older women are still able to carry a pregnancy.


Egg donation success rates

The success rates of IVF treatments with donor eggs are therefore age-independent, because what is important is the age of the eggs. In the case of egg donation and single embryo transfer (SET: Single Embryo Transfer) at the blastocyst stage, the pregnancy rate is around 65%. If two embryos are transferred (DET: Double Embryo Transfer), the success rate is 65% to 80%. When transferring two embryos, however, it should be noted that the probability of a twin pregnancy is about 25% to 30%. A twin pregnancy is considered a high-risk pregnancy in every woman, especially in women over 40 years of age. This means that the risk is higher for both the woman and the child.
