Causes of infertility
Here is a list of the most normal causes of infertility. However, among 10% of couples no couse can be found - neither with the man or the woman.
A cause that is and has had a big role in the media. Factually women's fertilty decrease with age and Danish women decide to have children at an older age than previously.
Lack of ovulation
Often times caused by hormonal and hereditary circumstances, obesity - or the opposite - for example in conjunction with elite sports.
Insulin production and sensitivity seems a noteworthy cause of certain patients' weight problems and thereby also ovulation.
Adhesion of the uterine tubes
When adhesion of the uterine tubes occur the sperm cell can not make its way to the egg cell. Adhesion of the uterine tubes can also make it harder for the tubes to catch the egg cell. Adhesion can occur after genital infection and after STDs such as chlamydia and gonorrhea.
Changes to the uterus
Uterine fibroids and polyps can prevent fertilized eggs from settling in the uterus.
Low sperm count
If there is not a sufficient number of sperm cells to swim to the egg cell the egg will not be fertilized. Hedetary circumstances, unhealthy lifestyle, environmental factors, certain diseases and use of muscle-enhancing drugs can lead to low sperm quality.
Poorly packed genome
Can be the cause of insemination and IVF failure. Abnormalities with the man or woman's chromosomes or issues with the quality of the egg are among the problems related to the genome. Recent research has contributed another factor that has proven to have a big impact on the succes of fertility treatment; poorly packed genome of the mans sperm cells. For among 20-25% of couples who recieve fertility treatment the man's sperm count will be low due to poorly packed genome.
Age, smoking, alcohol, coffee and over or underweight have significant impacts on fertility.
