Infertility, which affected 48.5 million couples worldwide in 2010 alone, has many causes; some causes result from issues related to the endometrium. Unfortunately, no cure exists for medical conditions resulting in the destruction of the endometrium, or for non-functional uterus. Thus, safe and effective therapies are needed to treat these diseases and to establish fertility in affected women. These novel techniques refer to the use and application of regenerative/paracrine factors to regenerate the endometrium in patients with Asherman's Syndrome (AS) and Endometrial Atrophy (EA).These new therapies based on the injection of the identified regenerative/paracrine factors and the platelet-rich plasma (PRP) from whole blood in an immunodeficient mouse model with AS/EA, evaluating their contribution and/or effect in the endometrial repair by functional proofs.
