Pregnancy after 40 – facts you need to know
Crossing the age of forty does not rule out the chance of getting pregnant and giving birth to a healthy child. Nonetheless, late pregnancies—those after 40—require more effort to maintain and bring to a happy conclusion, namely childbirth. It is worth remembering that the period of a woman's maximum fertility occurs between her 20th and 25th year of life. Meanwhile, for women in their thirties, the chances of pregnancy are already smaller, amounting to approximately 15–20%, and after the age of 35, female fertility declines even further. All women over 30 need to know that the length of the luteal phase of the cycle may shorten and so-called anovulatory cycles, during which fertilization cannot occur, happen more frequently. Progressive processes in the aging body also negatively affect ovarian tissues.
When talking about the ability to conceive, we refer to specific age ranges. We indicate when the most appropriate time for effective fertilization and giving birth to a child occurs. Meanwhile, the issue of ovarian reserve also arises. What does this term mean, and what exactly does it inform us about? Let us start by explaining that every woman is born with a specific pool of gametes capable of fertilization, meaning the body does not produce new reproductive cells, but stores a fixed number of them from the moment of birth. Ovarian reserve thus gradually decreases with age, and female fertility declines until menopause, which ends a woman's reproductive period. Additionally, what must be kept in mind is that reproductive cells age along with the woman's body, so their quality also weakens. In connection with this, we now understand why female fertility is the greatest obstacle to achieving pregnancy after the age of 40.
– It is true that with each passing year, it becomes harder for a woman over 40 to get pregnant. The body ages, and along with it, the reproductive cells. Motherhood, however, is not ruled out. Although it requires more effort and commitment from both the women and the medical staff, by utilizing modern medicine and the knowledge we are constantly gaining, we can achieve pregnancy. On the other hand, the fertility of each woman is a very individual matter, as it depends on lifestyle, physical activity, daily diet, or the use of stimulants. Apart from cases where a woman cannot conceive due to biological reasons, it is worth not postponing parenthood explains Magdalena Ziętara, MD, Ph.D, obstetrician-gynecologist and fertility treatment specialist from the Bocian Clinic in Łódź.
Pregnancy after 40 and childbirth
Around the topic of late motherhood, a statement often appears regarding the necessity of performing a C-section, because the woman's body is no longer strong and capable enough for natural childbirth. However, this will not prove necessary in every case, as everything depends on the course of the pregnancy and the woman's health status. A C-section is performed only when medical indications arise.
The hardships of pregnancy, childbirth, and caring for a newborn offspring are a demanding time for every mother. After the age of 40, a woman's body finds it harder to endure physical burdens, usually associated with poorer overall physical condition or pre-existing chronic diseases. However, this is not a rule, as every pregnancy is a completely different case.
Pregnancy after 40 and child development
Every pregnant woman is always concerned about the proper development of the fetus. She takes care of herself, uses the help of professionals, and finds emotional support among family and loved ones during this special and demanding time for the expectant mother. However, it must be taken into account that with a woman's age, the probability of developmental or genetic defects in the fetus increases, e.g., Down syndrome – trisomy 21. Women over 40, being under the special care of specialists, are referred for specialized, highly thorough examinations that enable the detection of possible fetal abnormalities.
Pregnancy after 40 – risks and challenges
If a woman, for various reasons, conceives much later, she must be aware that there is a group of risks and certain challenges for both her body and the child. In addition to declining fertility, after the age of 40, the risk of complications increases, and childbirth may be:
- longer and more difficult,
- the baby will be born early – premature birth,
- a miscarriage will occur.
The risk of disorders and diseases of the female reproductive system also increases, such as:
- uterine fibroids,
- endometrial polyps,
- uterine cancers.
Additionally, conditions such as the following may occur:
- gestational diabetes,
- high blood pressure,
- other perinatal complications.
A woman's age can be a factor influencing the occurrence of congenital defects in the child, including Down syndrome.
Preparing for pregnancy after 40
Pregnancy after forty, being considered high-risk, prompts the expectant mother to continuously take care of herself and prepare well for it. In what scope? This can be done through:
- maintaining a balanced, wholesome diet,
- reducing or avoiding stress,
- eliminating stimulants: cigarettes, alcohol, or caffeine,
- ensuring sleep hygiene,
- using supplementation supporting fertility in consultation with a doctor (including folic acid, vitamin B6, Omega-3 fatty acids, zinc, magnesium, iron),
- mental state – maintaining a positive attitude.
Pregnancy after 40 – what tests?
Taking into account that conceiving and maintaining a pregnancy after 40 is more difficult, a woman undergoes more detailed examinations that will allow her to achieve the desired pregnancy, maintain it, and give birth to a healthy child. Among the tests worth performing are:
- Pap smear,
- breast and reproductive organ ultrasound,
- complete blood count (CBC),
- blood sugar levels,
- urinalysis,
- blood pressure measurement,
- assessment of ovarian reserve – AMH (anti-Müllerian hormone).
In addition, to obtain complete information about the patient's health status, the doctor must know how efficiently her endocrine system functions. Therefore, during the visit, the specialist explains and orders which hormones to test before pregnancy.
During pregnancy, the pregnant woman will also require a series of examinations. It should be remembered that she has the right to undergo non-invasive prenatal screening for the most common developmental defects and genetic abnormalities. Diagnostics includes genetic and mid-trimester (anatomy) ultrasound scans, as well as biochemical tests (PAPP-A test – aimed at evaluating the level of PAPP-A protein in the mother's blood).
Diagnosis and treatment of infertility after 40
Natural aging processes occur in a woman's body that cannot be stopped. After the age of 40, achieving pregnancy is more difficult, and in some cases, the chances may be negligible. Fortunately, in the medical market, there are certified facilities where a woman can receive expert help and fulfill her dream of having a child. A fertility clinic such as the Bocian Clinic provides basic and advanced diagnostics as well as state-of-the-art treatment methods. The specialists working there are highly qualified medical staff who help achieve pregnancy and fulfill parental dreams. – When pharmacological therapies or other medical procedures prove insufficient, it becomes necessary to use assisted reproductive technologies – such as insemination or in vitro fertilization (IVF). Additionally, in the case of IVF, preimplantation genetic testing (PGT) can also be used to examine embryos for genetic diseases. On the other hand, in a situation where a woman no longer has her own egg cells capable of fertilization, she can also consider using anonymous oocyte donation adds Magdalena Ziętara, MD, PhD, obstetrician-gynecologist and fertility treatment specialist from the Bocian Clinic in Łódź.
In vitro with a donor egg
The IVF procedure using a donor egg cell allows women to fulfill their plans of motherhood and offers a chance to give birth to a healthy child. At the Bocian Clinic, we have our own egg and embryo bank. Thanks to this, we can quickly check the availability of donor oocytes with an appropriate phenotype and accurately determine the waiting time for IVF. The entire qualification process of donors takes place directly at the clinic and is conducted by our specialists.
Becoming a mother after forty
For most women, motherhood is a desired stage of life. However, as it turns out, not every couple can achieve pregnancy right away, or they postpone decisions about parenthood for later. Because the pool of oocytes depletes with each passing year and female fertility declines, procreative chances after the age of 40 decrease. However, modern medicine offers many effective methods of fertility support and treatment, including the IVF procedure, which will help a woman become a mother.
