Causes of unwanted childlessness

Causes of unwanted childlessness

What can make it fail?

Unwanted childlessness always affects both partners. The search for the causes must therefore always be carried out by both partners. The reasons for unwanted childlessness are manifold and are evenly distributed between men and women. In some cases both partners have causes of infertility, while in other cases there are no recognisable causes at all for the absence of pregnancy.
In addition to organic, immunological and biological causes, psychological aspects also play a role. Environmental pollution, stress, being overweight, unhealthy diet, excessive consumption of alcohol, coffee, drugs and smoking can also affect fertility.

Causes of unwanted childlessness in women

Dysfunction of the ovaries

Functional disorders of the ovaries are usually caused by hormones. Hormonal dysfunctions can lead to irregularities in the cycle, disturbances in egg maturation, lack of ovulation and insufficient formation of the corpus luteum. The hormonal imbalance can be caused by any form of stress, inflammation, injury, tumour, being underweight or overweight, rapid extremes in weight changes, severe physical stress, congenital dysfunction of hormonal glands, medication, environmental pollutants and stimulants. Malformations of the ovaries can also be hereditary.

Fallopian tube infertility

Damage to the fallopian tubes can occur in many variations and is usually caused by inflammation. Inflammations can lead to the closure of the fallopian tube ends (fringe funnel) and to adhesions of the fallopian tubes. However, ectopic pregnancies and adhesions after surgery can also impair the function of the fallopian tubes. In addition, malformations of the fallopian tubes can already occur during embryonic development or be hereditary. Damage to the fallopian tubes means that the egg collection mechanism and egg transport to the uterine cavity are disturbed or completely impossible.


Endometriosis is the colonisation of the outer lining of the uterus. It is presumably caused by uterine mucosa residues that are carried backwards through the fallopian tubes into the free abdominal cavity during menstruation. Endometriosis lesions are often found in the peritoneum, but also in the ovaries, fallopian tubes, intestines and bladder. Endometriosis can be treated with medication or surgery.

Polycystic Ovarian Syndrome (PCO)

The PCO syndrome is caused by hormonal disorders that begin at puberty. The degree of severity can vary greatly and ranges from a disturbed corpus luteum function to the complete absence of periodontal bleeding. Women with PCO syndrome produce more male hormones in the ovaries and/or adrenal cortex. As a result, enlarged ovaries are formed, which carry many small follicles, and egg cell development is disturbed.

Causes of unwanted childlessness in men

Testicular dysfunction

The most common disorder in men is limited formation of normal sperm cells that move well forward. Normally, one millilitre of semen should contain at least 20 million sperm cells, of which about one-third should be of normal shape. In order to ensure that a sufficient number of spermatozoa can travel the arduous path through the vagina, cervix, cavity and fallopian tubes up to the egg, at least half of the spermatozoa should be able to move forward. If the sperm values are below these normal values, a man's fertility is restricted. Testicular dysfunction may be inherited or caused by injury or accident. Varicose veins (varicocele) are also very common. Anomalies in the early childhood (testicular hypertension) that are not detected and corrected in time often lead to uncorrectable damage to the testicles. Sperm maturation disorders can also be the late consequence of a mumps infection in childhood. Febrile or infectious diseases can also temporarily restrict testicular sperm production. Excessive consumption of alcohol and nicotine as well as stress and environmental pollution are further factors that can have a negative influence on sperm cell formation.

Disturbed sperm cell-oocyte interaction

Irrespective of sperm density, functional disturbances can also hamper or block the penetration of the sperm into the egg and thus cause infertility.

Transport disorders of the vas deferens

In some men, a sufficient number of sperm cells are formed, but there are still few or no cells in their sperm, as these are obstructed by a blockade of the sperm duct. The causes of this may be a sticking of the vas deferens or epididymis ducts, which is the result of inflammation. However, closed or underdeveloped vas deferens can also be inherited. Injuries and operations (e.g. after inguinal hernia) can also result in a disruption of semen transport.

Very good doctor

We were in treatment from February 2018 to March 2019 with Dr. Döhmen and his team. We found ourselves in very good hands there. The whole team is super friendly. [...] If Dr. Döhmen wasn't there, his replacement Dr. Bender took over, this doctor is also great. So we can only recommend. Result: 35th SSW with twins.

Very good doctor and great practice team!

After several consultations in various fertility centres, we felt that we were in very good hands with Dr. Döhmen. At no time did you feel like you were one of many. This has always disturbed us in the other centres. We spent a total of 7 months with him in treatment and got to know Dr. Bender during this time - just as recommendable. Our wish came true - many thanks to the whole practice team. We will recommend you to others.

Very competent and sensitive doctor

We were treated by Dr. Döhmen for about a year. We felt very well taken care of during the whole time. The entire staff is always friendly and they are all super super sweet there! Unfortunately, the 3 ICSIs were not successful, but this definitely had nothing to do with the treatment method, but was due to my egg yield. It was a very emotional time and the whole team was very hard working and sensitive. Thanks for that!

Highly recommended

A good practice works best in a great team, where doctors and employees work hand in hand. We felt very well looked after and in good hands. Without your professional skills and your necessary empathy, our wish might have remained a wish. We would like to thank you and your entire team for supporting us in fulfilling our dream.

Successful fertility treatment

We were treated by Dr. Döhmen from August 2017 to August 2018. He's very straightforward, matter-of-fact and doesn't revolve around anything. You know immediately where you are and what the possibilities are. We personally welcomed the honest and direct way all professional and medical information was understandable. Team also always very dear and endeavoured. [...] We are now in the 32nd SSW and thus in the final spurt and would go again and again to Dr. Döhmen in the practice.

Satisfied all round

On the recommendation of friends we turned to the practice and were treated by Dr. Döhmen. We had an ICSI and we had immediate success with the first attempt. Our healthy daughter was born in December 2018. We felt well taken care of during the treatment and were very satisfied all around.

Great time

We have been made aware of this practice by my gynaecologist. During the six months of treatment we felt comfortable and understood our problem. We never felt like we were alone. All doctors and assistants were very happy about our pregnancy. Thanks for a great time!

Very professional and empathic practice team and excellent physician

I am a doctor and have been recommended the practice by a colleague. It was our third ICSI attempt after unsuccessful attempts outside. The support by Dr. Döhmen was excellent from the very first day, very professional and all our questions were answered. The support by Dr. Döhmen in the treatment cycle but also by the entire team was great and very positive so that we were also very positive. The puncture and embryo transfer were very relaxed and professional. I was doing very well the whole time, all questions were answered. We actually got the wonderful news to be pregnant with twins and I am now in the 13th SSW. I can wholeheartedly recommend the Döhmen/Schalkalk practice and wish all couples who wish to have children every success.

Very competent and friendly team

We were in treatment for almost a year. The second cryo seems to have worked. The team was at all times very busy and always nice and friendly. Competence cannot be questioned. The successes speak for themselves. I would recommend this clinic to everyone and would be happy to come back if I wish to have more children.

Successfully released from practice. Thanks to God, Dr. Döhmen and the great team, I have been a mother for a year now. After six years of unsuccessful desire to have children, this practice and this doctor were my very last hope. I can't say enough thank you, Dr. Döhmen, and see you next time.
