It is a biological fact that in all women in their late 30s, approximately 60-70% of all oocytes are genetically modified in such a way that pregnancy, biochemical pregnancy (after a positive pregnancy test, the period is delayed) or miscarriage often does not occur. This explains why it sometimes takes many attempts before a pregnancy occurs and that some couples with a late desire for children remain childless. Meanwhile, it is also known that the age of the man plays a not inconsiderable role in fertility and with increasing age of the man the sperm quality decreases and the probability to father a sick child increases slightly.
Laboratory and ultrasound examinations can be used to estimate the number of follicles in the ovaries, but they do not tell us anything about the quality of the follicles. It is therefore very difficult to estimate how fertile an older woman is compared to her peers. The aging of the ovaries is individually different. The fact is, however, that fertility in women declines sharply from the age of 35 onwards and is usually stopped at 43. It is rare for a pregnancy to occur beyond this age limit, even if methods such as artificial insemination are used.
Based on these facts, it is advisable not to postpone family planning unnecessarily and to discuss the biological relationships with your partner. If pregnancy does not occur after one year, you should contact us for a clarification and if you are older than 35 years after only 6 months and if there are irregular menstrual cycles or other health problems.
