A woman's age significantly affects the condition of her oocytes, fertility, and the likelihood of becoming pregnant. With age, the quantity and quality of oocytes decline, which also increases the risk of miscarriages and chromosomal abnormalities.
In addition to age, many other factors affect female fertility.
The fertility of women begins to decline around the age of 30, and the decline accelerates after the age of 35.
Seek examinations:
Below is a description of examinations related to female fertility at the appointment and possibly thereafter. Further examinations are always tailored individually based on the findings.
The examinations proceed step by step:
The physical examination includes an assessment of the woman's general condition and gynecological organs, such as a speculum examination and palpation of the lesser pelvis.
Ultrasound scan provides additional information on the structure of the uterus, fallopian tubes and ovaries. It can be used to determine the number of antral follicles, which reflects the functional reserve of the ovaries.
You will receive instructions on how to perform an ovulation test and determine the length of the luteal phase.
Hormone tests are an essential part of fertility assessment. Tests often measure AMH (Anti-Müllerian Hormone), FSH (follicle-stimulating hormone), LH (luteinizing hormone), TSH (thyroid-stimulating hormone), progesterone, and prolactin. Other hormone tests are also performed as needed. These hormones affect ovulation and general reproductive health. If necessary, other basic blood tests are also taken.
The uterine cavity can be examined, if necessary, with fluid instillation added to an ultrasound scan, with a biopsy, or by hysteroscopy.
Based on the research results, an individual treatment plan is drawn up.
co-parenting
Co-parenting parenthood makes it possible to have a child in a situation where both parties wish for a child without a romantic relationship.
In vitro fertilisation (IVF)
Are you considering IVF treatment? Felicitas Mehiläinen offers comprehensive IVF treatments, expert support, and a clear treatment path.
The fertility examinations for women generally include an initial assessment, a clinical examination, blood tests to determine hormone levels and ovarian function (such as AMH, FSH, LH, TSH, prolactin), and an ultrasound scan to examine the uterus and ovaries. If necessary, other additional examinations, such as a fallopian tube patency test, are also performed. Regarding primary diseases, a written assessment performed in advance by the attending physician on the risks of pregnancy is an important addition to the overall situation assessment.
It is often possible to improve female fertility with various treatments and lifestyle changes. A treatment plan is always drawn up individually based on the examination results.
The AMH (Anti-Müllerian Hormone) value is a value measured by a blood test that indicates the ovarian reserve of egg cells, i.e., the current number of remaining early egg cells. It provides important information about a woman's fertility status and helps assess the peak of fertility.
The best time to seek infertility examinations is when pregnancy has not occurred after a year of trying. Women over 35 should seek examinations after just six months of trying, as female fertility decreases with age.
The fertility of women decreases most after the age of 35. After this, the probability of becoming pregnant decreases and the risk of miscarriage increases.
The fertility of women usually ends with menopause, when the function of the ovaries ceases and eggs are no longer released. This happens on average around the age of 50, but there is great variation.
Kuukautiset eivät aina merkitse sitä, että ovulaatio eli munasolun irtoaminen tapahtuu. Ilman ovulaatiota raskaus taas ei voi alkaa.Jos kuukautiskiertosi on lyhyt, esimerkiksi 23 päivää, voi olla, että ovulaatiota ei tapahdu. Näin voi olla myös, jos kierto on paljon yli 28 päivää. Vaikka ovulaatio tapahtuisikin, lyhyissä ja pitkissä kierroissa kohdun limakalvo ei aina pysy tarpeeksi hyvässä kunnossa alkion kiinnittymiseksi.
