It is a fact. More and more women are aiming to become mothers in their 40s, or even later. According to INE data, the number of women in our country who have their first child after the age of 40 has doubled in the last 20 years. Social, cultural and economic changes are behind this decision. Sometimes, delaying motherhood is motivated by the need to have a good job and economic stability. Other times, it is because the right partner is slow to arrive or does not arrive at all. Or it may also happen that the woman wants to become a mother again at 40 with her new partner.
Whatever your reason for wanting to become a mother at 40 or older, it is important to know what your real reproductive options are, taking into account the advantages, risks and assisted reproduction techniques that can undoubtedly help you achieve your dream of becoming a mother at an older age.
The best biological age to become a mother
From a biological point of view, a woman’s fertile years begin in adolescence approximately one year after having regular periods. This optimal stage of fertility is maintained until approximately 27 years of age, at which time it begins to decline gradually. It is after the age of 35 when the ovarian reserve decreases significantly and problems in achieving pregnancy may begin. When a woman reaches the age of 40, the chances of a natural pregnancy are reduced to 5% and, after the age of 45, the chances of achieving a pregnancy with a woman’s own eggs are really minimal. But in addition to reduced fertility, the risk of miscarriage and genetic abnormalities increases.
Fertility preservation
For those women who wish to postpone childbearing (out of their own desire or for medical needs), fertility preservation by freezing eggs at a fertile stage is a very suitable option. This technique allows women to decide when is the best time to start a family, using their frozen eggs for in vitro fertilisation (IVF) treatments in the future, even when they are over 40 years old. At the Tambre Clinic, we offer the most advanced techniques for oocyte cryopreservation, ensuring the best possible quality for future fertility treatments.
Reproductive options after the age of 40
Due to the natural aging of the ovaries, a woman 40 years of age or older is most likely to have a low ovarian reserve. This means that the number of eggs available to achieve pregnancy is decreasing. But, to make matters worse, the quantity of eggs is reduced, and so is their quality. This is why, after this age, genetic mutations and aneuploidies (such as Down syndrome) multiply, which can lead to miscarriage or the birth of a baby with health problems.
In order to avoid all these problems and to be able to have a healthy child at the age of 40, nowadays we have different assisted reproduction techniques:
IVF with PGD
The combination of In Vitro Fertilisation (IVF) with Preimplantation Genetic Diagnosis (PGD or PGT) is the most highly recommended option for women over 40 who wish to become mothers. Through ovarian stimulation, we are able to increase the chances of pregnancy and, thanks to PGD, which is performed before the embryo is transferred to the uterus, we can select genetically healthy embryos. This improves implantation rates, decreases the risk of miscarriage, and offers a better chance of delivering a healthy baby.
Ovodonation
If the woman’s ovarian reserve is already very low and she cannot obtain enough quality eggs for IVF, one of the options is to resort to oocyte donation.
IVF with oocyte donation is the most effective assisted reproduction technique. This procedure involves the use of eggs from a young donor (18 to 35 years old), who has previously undergone various medical examinations to ensure that she is healthy.
At Tambre we have an exclusive egg donor program that allows us to find the ideal donor for each patient. For this reason, in addition to the serologies, Tambre also performs an additional study on the donor that includes: genetic analysis with karyotype, cystic fibrosis, beta-thalassemia and Fragile X, as well as a psychological evaluation.
The selection of the donor
The selection of the donor is also based on the physical characteristics (race, skin colour, eye and hair colour, complexion, size, etc.) of the woman receiving the eggs, so that the offspring will have a physical resemblance.
Finally, the chosen eggs are fertilised with sperm from the couple or from an anonymous donor. The resulting embryos are transferred into the uterus, increasing pregnancy success rates and reducing the risks of genetic abnormalities.
Genetic compatibility test
Genetic Matching is a test that helps us to know the genetic compatibility between the members of the couple, or between the egg donor and the male, or between the egg donor and the sperm donor.
This test allows us to study certain recessive genetic diseases linked to the X chromosome, and to check the probability of transmitting them to the embryo.
If in the test we discover that both parents have the same genetic mutation, and that it is possible that the baby will be born with a disease, we can perform a preimplantation genetic test of the embryos in order to transfer only the one that has inherited a single copy, or better yet none, of the defective gene. Another option would be to use a compatible donor (egg or sperm).
Embryo adoption
Another option to become a mother at 40 is to choose embryo adoption. This assisted reproduction procedure is faster and simpler than the rest. It consists of transferring an embryo to the woman. This embryo is donated by another woman or couple that has previously undergone IVF, and no longer wishes to have more children.
For the selection of embryo donors at Tambre we also follow very rigorous criteria to ensure that the donors are free of diseases and that they are compatible with the blood group and Rh of the recipient woman.
Advantages and risks of becoming a mother after age 40
Being a mother in your 40s has several advantages. Women at this stage tend to have greater maturity and emotional stability, as well as a better financial and work situation. Pregnancy is generally highly desirable, which reduces the incidence of postpartum depression.
However, pregnancy at this age carries certain risks that must be considered:
- Increased probability of miscarriage (greater than 30%)
- Risk of ectopic pregnancy.
- Hypertension and gestational diabetes.
- Preeclampsia and thromboembolism.
- Thyroid problems.
- Preterm delivery and higher cesarean section rate.
Because of these risks, pregnancies in women over 40 years of age are considered high risk and require more frequent gynaecological controls.
