Cell Free DNA Quantification in Patients With Endometriosis Followed Witd Medical Assistance to Procreation

Study Overview
=================
Brief Summary
-----------------
Endometriosis is a common benign disease in premenopausal women and causes chronic pelvic pain and infertility. This infertility may be due to pelvic adhesions and surgery but also because of poor oocyte quality. It is known that endometriosis is associated with an increase oxidative stress, wich induce chronic inflammation, deleterious effect for DNA, proteins and can caused cellular death. ROS markers found in follicular fluid or in serum are significatively higher in endometriosis women. The investigators want to dose a marker of apoptosis in infertile women and see if it's significatively higher in serum and in follicular fluid of patients with endometriosis compared to others infertility causes and if it's correlated to oocyte quality and IVF results. Real time PCR will be used to dose cell free DNA in serum and follicular fluid of patients undergoing IVF treatment (endometriosis and infertility due to tubal factor, male infertility or idiopathic cause). Then the investigators will compare cell free DNA rate with oocyte and embryo quality and with pregnancy outcomes in the different group.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: patients with endometriosis<br> | Biological: blood sample<br>* 10ml of blood will be sampled from patients before undergoing IVF treatment, the cell free DNA will be extracted and then quantified by a real time PCR. Another 10ml sample will be drawn the day of oocyte puncture for a new quantification of cell free DNA in plasma and cell free DNA will also be dose in follicular fluid of patients<br>|
| Active Comparator: others infertility causes<br> | Biological: blood sample<br>* 10ml of blood will be sampled from patients before undergoing IVF treatment, the cell free DNA will be extracted and then quantified by a real time PCR. Another 10ml sample will be drawn the day of oocyte puncture for a new quantification of cell free DNA in plasma and cell free DNA will also be dose in follicular fluid of patients<br>|
