Factors that can affect female fertility.

Unfulfilled fertility is a problem that affects many couples. In about one third of cases, the causes are to be found in the woman. Some of the most common causes of unfulfilled pregnancy in women are explained in more detail below.

Hormonal disorders

Hormonal disorders can cause ovulation not to occur or to be disturbed. A disturbance in thyroid function or hormone balance can be the cause. Polycystic ovarian syndrome (PCOS) can also be a hormonal cause of infertility.

Tubal and uterine problems

Adhesions or inflammation of the fallopian tubes can prevent an egg from reaching the uterus. A narrowed or blocked uterus can also be the cause. Endometriosis, in which the lining of the uterus grows outside the uterus, can also be a reason for infertility.


A woman's fertility decreases with age. From the age of 35, the probability of pregnancy decreases significantly. From the age of 40, it is more difficult to get pregnant naturally.

Unhealthy lifestyle habits

Smoking, alcohol and drug use, as well as an unhealthy diet and obesity, can affect fertility and make pregnancy more difficult.

Autoimmune diseases: Autoimmune diseases such as lupus or rheumatism can also lead to infertility.

Genetic factors

In rare cases, genetic factors may play a role. A hereditary predisposition to disorders of egg maturation or hormone production can make it harder to get pregnant.

To determine the exact cause of infertility in women, a comprehensive medical examination is necessary. A thorough medical history, blood tests, and ultrasound examinations of the uterus and ovaries can help determine the cause. Depending on the diagnosis, further treatment options can then be discussed to fulfill the fertility.

Overall, it is important to emphasize that every woman is different and that there is no blanket answer to the question of why a pregnancy does not occur. Professional medical consultation and individualized care are therefore essential to determine the cause of the unfulfilled desire to have a child and to find a suitable treatment.
