Endometriosis is a condition for which little is known about the causes and the reasons why it appears and develops. It seems that there is a type of women that are more prone to experience it due to genetic and immune reasons. It appears in these patients through a process of "retrograde menstruation" through the fallopian tubes and, subsequently, along into the abdomen.

The usual advice is to go and see a doctor if you have been trying for a baby for two years without success. However, bearing in mind that time is very important in terms of fertility, we recommend you see a doctor as soon as you suspect there may be a problem, this doesn't mean that you need to undergo an assisted reproduction technique immediately, it just means that any issues can probably be resolved with some medical treatment.
