I'm trying to get pregnant, but I've heard that it can be difficult. What are some of the most common reasons that couples have trouble conceiving?

Common reasons for difficulty conceiving include age, lifestyle habits, genetics, medical conditions, and environmental factors. Age is a key factor in fertility as women over 35 may experience decreased fertility or difficulties becoming pregnant. Lifestyle habits such as smoking, drinking alcohol, and not getting regular exercise can also affect fertility. Genetic factors like abnormal chromosomes or hormone imbalances can make conception more difficult. Medical conditions like polycystic ovarian syndrome (PCOS) and endometriosis can also cause issues with fertility. Environmental factors like air pollution, chemical exposure, and electromagnetic radiation can all interfere with reproductive health.
