Uterine Irrigation Method in Infertility Patients Who Require PGD

The Histological and Genetic Investigation of Cells, Fluid and Tissue in the Uterine Cavity, Using the Uterine Irrigation Method, in Patients Who Suffer From Unexplained Infertility and Hereditary Genetic Disease, and Who Require PGD Scans.

The study will involve up to 30 pairs of male and female sexually intimate partners who are carriers for a genetic disease (e.g Sickle Cell Disease or Thalassemia) and at high risk of transmitting the gene. The female partner will be superovulated to mature multiple oocytes which can be fertilized, inseminated with her partner's sperm through intra-uterine insemination (IUI). Four to six days after IUI, the female partner will undergo a non-surgical uterine lavage procedure to recover preimplantation embryos.

The study is a prospective, single center, single-arm study to evaluate healthy cells which do not carry illnesses, by collecting and performing the histological and genetic analyses of blastocysts, endometrial tissue and cells, which have been formed in the uterus, without any burden of the morbidity and mortality caused by the oocyte collection process, and which thereby have not been subjected to any iatrogenic intervention, with uterine lavage. The study will involve up to 30 pairs of male and female sexually intimate partners who are carriers for a genetic disease (e.g Sickle Cell Disease or Thalassemia) and at high risk of transmitting the gene. The female partner will be superovulated to mature multiple oocytes which can be fertilized, inseminated with her partner's sperm through intra-uterine insemination (IUI). Four to six days after IUI, the female partner will undergo a non-surgical uterine lavage procedure to recover preimplantation embryos. Following lavage, a GnRH antagonist will be administered to cause lysis of multiple corpora lutea to mitigate risk of hyperstimulation from the use of fertility medication and reduce the risk of ectopic pregnancy should the lavage procedure not recover all preimplantation embryos. Recovered preimplantation embryos may be screened for aneuploidy and genetic disease, then cryopreserved for potential future use by the subjects and the Investigator separate from the purpose of this study. Each subject participates in the trial for up to 10-20 weeks.

Four to six days after IUI, the female partner will undergo a non-surgical uterine lavage procedure (Previvo Uterine Lavage System™, CA, U.S.A.) to recover preimplantation embryos.

The PI places the Lavage Catheter per instructions for use Use of a tenaculum or cervical stitch is required Use of saline to wash the cervix is required Use of abdominal ultrasound guidance with a full bladder is required The PI records if there was clinically significant fluid loss through the cervix.
