Endometriosis is a disease caused by the presence of the endometrium (the layer that lines the uterus inside and where the embryo must nest), outside its normal location: in the ovaries, pelvis, etc.   The endometrium is responsible for menstrual bleeding (every 28 days, if it is not nested by an embryo, it is expelled with menstruation); but when it is out of its normal location, it produces small bleeds that give rise to the so-called “chocolate cysts” in the ovaries, as well as inflammatory phenomena (pain), when it is in the pelvis or other locations

A few days ago, we were talking about the ¨Low Reserve¨ (few eggs); Today we will talk about ¨Low Response¨, often confused, even in medical literature, with the previous one, but with a different origin and treatment. The ¨Low Response¨ is that situation in which, having sufficient quantity of ovules available in the ovaries, but these do not respond adequately to the treatment; the end result is what makes this situation similar to the “Low Reserve”: few eggs available.  

The amount of a woman’s eggs decreases from the moment of birth, over the years, until menopause is reached. It is estimated that women are born with approximately 2 million eggs. This figure decreases over time and when they reach adolescence, they have about 40,000 eggs. Eventually, only about 400 become ovulated, usually 1 for each menstrual cycle.
