A first initial consultation for prescription of the infertility assessment,~a consultation 2 summarizing the examinations and delivery of prescriptions~a blood sample: basal hormonal assessment with AMH (Anti-Mullerian Hormone),~a urine sample to look for an infection with Chlamydia Trachomatis, which is one of the bacteria responsible for gynecological infections compromising ART.~an HPV (Human Papillomavirus) test on vaginal swab~a consultation 3 corresponding to the start of a treatment cycle for IVF with oocyte retrieval at the end of this treatment cycle.~A consultation lasting 4 to 4-6 weeks to take stock of the success or failure of the ART.~A pregnancy follow-up consultation if successful, for a pelvic ultrasound, then monthly pregnancy follow-up (one consultation per month).~As part of the usual ART monitoring, clinical and paraclinical data are collected using the MEDIFIRST software.~During the inclusion visit, questionnaire => will be completed over an additional time to the consultation if inclusion is desired, inclusion time provided by one of the doctors participating in the study.~For the FERTITHEQUE, will be collected:~clinical characteristics collected at each consultation as part of the usual follow-up.~biological characteristics measured as part of the usual follow-up.~During consultation 2, during a blood test carried out as part of your usual care, additional tubes will be taken (4 to 5 tubes of 10mL) to carry out the banking of DNA (support of genetic information), plasma (plasma library), serum (serotheque).~During consultation 2, a swab will also be taken from the vaginal microbiota.~During consultation 3, a conservation of the follicular fluid (puncture fluid) will be carried out.~During consultation 4, a plasma library will be performed again, whether there is pregnancy or not, as well as a new swab sample for the vaginal microbiota.~Then, as described above, patients are after inclusion as part of the usual IVF follow-up reviewed at 1 month for oocyte retrieval then at 2 months for the follow-up visit allowing observation of success or failure of the treatment cycle.~If pregnancy is achieved, patients are seen monthly as part of their usual follow-up until delivery.~If a pregnancy is not achieved, follow-up stops.~Whether or not a pregnancy is obtained, during the visit at 2 months (V4), a plasma library and a vaginal microbiota are again performed.
Creation of a patient library in Medically Assisted Procreation to allow the implementation of further research with the following objectives:~To identify new relevant biomarkers in patients who will carry a pregnancy to term~To better specify or identify new infertility risk factors~To identify new relevant biomarkers in patients with reduced ovarian reserve~Four consultations are planned with biological et clinical collection.
