Asthma linked to an increased time to pregnancy

Asthma has been associated with a prolonged time to pregnancy and a decreased birth rate in a new clinical observation study. The current study investigated 245 women with unexplained fertility problems aged between 23 and 45 years. They underwent asthma and allergy testing and questionnaires during their fertility treatment. 96 women in the study had either an existing doctor’s diagnosis of asthma or were diagnosed with asthma when they entered the study.
