Unexplained infertility should really be referred to as “unexplained medically”. It is not a diagnosis, it is a failure to diagnose. If a semen analysis is satisfactory and the woman’s Day 3 and Day 21 bloods don’t show anything then the failure to conceive is often labelled “unexplained”. There are a whole range of other factors such as weight, exposures to toxins, emotional and nutritional status which are not considered by the medical profession which can be the underlying cause. By adopting a nutrition and lifestyle programme that specifically targets fertility health it is possible to succeed to conceive, usually within 3 months.
