Unexplained Infertility Among Asthmatic and Atopic Patients
Recruitment status was: Recruiting
Unexplained infertility is defined as the lack of thec ability to become pregnant during the first year, although the periods of the woman, the semen from the man and the laparoscopic findings are normal. In Denmark do roughly every fifth to seven couple in the fertile age have problems becoming pregnant for a various kind of reasons, of these are 10-15 % unexplained infertile.
Many factors are pointed out as imported. In particularly lifestyle factors such as the diet, smocking, obesity, lack of physic activity and alcohol. The causal connection is yet to be found, but it is assumed that there is a link between infertility and endocrine, neurological and immunological factors.
Asthma and allergy are some of the most common diseases among young people in western world .The development of these diseases are caused by both hereditary factors, and factors that also seem to be important in infertility.
It is clinically observed that many unexplained infertile patients simultaneously suffer from asthma and allergy. Furthermore this group of patients seems harder to treat in terms of becoming pregnant during fertility treatment then healthy not asthmatic and non allergic persons.
There is limited available data about this subject and the data that is already collected does not show a clear tendency.
Hypothesis: Atopic asthma is characterized by a systemic inflammation and can therefore be the reason for infertility among this group of patients.
The aim of this study is to examine whether female asthmatics and allergic are less fertile then healthy females- whether there is there a link between asthma and infertility. Furthermore if an optimal asthma treatment during fertility treatment reduces time to pregnancy.
